Homemade solar panels are very easy to make and use, because then materials required to make them are so easily available with the DIY guides. The amount of insolation we receive in a day can meet the energy requirements of a 100 earths! If this weren’t true then why would Japan plan to put the largest solar panel array in space?! They call it the Space Solar Power System; the largest source of clean and inexhaustible energy. This ambitious project will be in space by 2030; the array, 5 times more efficient than any on the earth, will collect the solar energy and beam it down to the earth via laser beams and microwaves.

Each solar cell can produce a certain wattage of electricity, when you buy your solar cells check their wattage. To make your own homemade solar panels calculate your energy requirements and then choose the number of cells such that their wattage should total to your requirement. The other things on your list to find or buy are and inverter, wires to interconnect the solar panels, plywood, wood, glass or plexiglass, rechargeable batteries and tools.

Let us begin making our homemade solar panels. You begin by placing your solar cells on a board of ply wood. Check where the two wires are most stretched out, and make a hole in the plywood with a drill. Now pass the two wires to the other side; do this with all the solar cells you have placed on the board. It would help to firmly fix the solar cells in their place with silicon if you don’t have it, Araldite should do too. This prevents strain on the wires and prevents them from shaking, touching each other or breaking due to brittleness. Now when you have all the cells fixed and the wires at the back of the panel, connect them all in a series of parallel series. Fix these wires on the back of the solar cell’s panel; this will make them firmer and fixed in their place. At the end of all this you should have an unconnected wire at the beginning and at the end of the series or parallel arrangement of the solar cells.

Now either you could place another plywood board at the back to cover all these interconnected wires, Or make a frame such that the front or the faces of the solar panels are exposed to sunlight and covered with the plexiglass. The back of the frame could also be covered with a panel carrying the cells, fixed midway between the two covering panels comprising the frame. The later is a better idea as you have to weather proof your solar cells, you do not want rain to get inside your panels! Also, make a hole at the backside bottom of the back panel. This will offer ventilation and remove residual moisture. Now connect the two wires at the beginning and end of the panel you created to the rechargeable battery. Your battery will be charged in approximately 8 hours. Completing your homemade solar panels, attaching the inverter is to convert the DC current to AC which keeps your appliances running safely.

   

If you are considering availing to the benefits of solar power then get a solar panel kit. The benefit being that you can learn to make it and save up to $10,000 or more in setup costs. As you know, to make it you can make more for your use and even take orders from others to make systems for them. Also, as you know to make them, you can fix them and keep them in high state of maintenance.

It will be a service to the earth and humanity as this is a non-polluting, inexhaustible source of energy. You can buy readymade solar energy systems in the market but they cost higher than the ones made at home. Solar panels need to be installed when you buy a solar panel kit; it comes with all the instructions. The biggest benefit of these panels is that they are cheaper compared to the commercial systems.

You can buy them online here and in the retail market; the whole setup may cost you $250. A solar panel kit comes with all the necessary components like the soldering iron, flux, solder, tabbing solar cells and step-by-step instructions of how to make the panel and use it. These panels are so simple that they can be used for classroom projects or for use at home. They can be built in custom sizes built to meet your needs perfectly.

One can build up to 1.5 kW panel arrays which can be easily be assembled by a child! The main part of the solar panel kit is the photovoltaic cells: these trap the solar radiation in the panel and convert it into electrical energy, facilitated by the photoelectric effect in the silicon chips embedded in the cell. The photovoltaic effect simplified is conversion of light (photos) into volts (electricity) at the atomic level. All the light absorbed gets converted into electricity. Therefore, you could enhance your system by reflecting light back onto the solar cells to enhance the rat of electricity generation.

The other components may be glass, plywood, plexiglass, wires, solders, a power inverter, switches, mounting devices, fuses, grounding system and a complete guide on how to use these components to build your solar panel. You can set up this panel in the backyard or on the roof where it receives full and maximum sunlight. The best part about a solar panel kit is that it begins to generate electricity as soon as it is set up. Attach rechargeable batteries allow them to charge for 8 hours you will have a ready source of electrical energy.

As the electrical energy is generated in DC you need to convert it into AC, this is done using an inverter. Your appliances can now be run safely. Once set up your faithful solar energy will last you a good quarter of a century, imagine the amount of money you would have saved by then. You begin to save 80% of your electric bill multiply the amount with the number of months in the 25 years, huge savings aren’t they?

Did that sound complicated?

Solar Charge Controller
The sun’s solar energy can be harnessed. The solar power cells store the solar energy as direct current in them. This direct current can be easily converted to alternating current with the aid of a special inverter called grid tie inverter. The photovoltaic cells and the grid tie inverter belong to the solar power unit of your home.

The grid tie inverter is an appliance which is specially designed to meet the needs of solar current. Another such specially designed electrical appliance is the solar charge controller.

The solar charge controller is also an essential part of the solar power unit. The primary function of a controller is to regulate charge flow in accordance to the conditions of the flow. For instance a 12 volts household utility controller will condition the charge flow to a maximum of 170 watts only and not more than that. The controllers are equipped to suspend the circuit and control the current flow in case of an excess current flow.

The two prime technologies applied by the controllers are the Pulse Wave Modulation (PWM) technology and the Maximum Power Point Tracking (MPPT) technology. A PWM controller slowly pulses down the current flow in case of an emergency. This slow pulsing enables the solar power unit to maintain a optimal flow of current, even when there is too much excess charge flow in the circuit.

The MPPT controller has a unique operating principle. It is operated by using audio frequencies of very high range (20-80KHz). A MPPT controller works by comparing the voltage output from the solar panels with that of the battery voltage. So when there is a huge gap in these two values, for example on a cloudy day, the controller helps boost up the electricity production. The grid tie inverter systems are often equipped with an in-built MPPT solar charge controller. Another advantage of the MPPT over the PWM is that, MPPT has much less wiring requirement than a PWM.
The disadvantage of MPPT is that, their working can be disrupted in the presence of a high frequency noise source. Even, the high frequency wavelengths of a radio transmitter can disrupt the working of the controller.

Another important function of a charge controller in a solar power unit is to control reverse current flow in the circuit. This happen mainly during the night when the photovoltaic cells cease to work. Apart from this charge controllers also perform additional duties of short circuit protection and lightning protection.

A household solar charge controller typically weighs between 159 to 160 gms.(0.35 lb) approximately.

Solar roof shingles are used to do the roofing of the house. They look like the conventional shingles made out of asphalt. Solar shingles have solid solar panels the size of regular shingles. They come in strip and semi-rigid designs which contain several silicon solar cells. The latest designs have the more efficient film solar cells which make the solar shingles even more flexible. The solar shingles are an award winning design which made the roofs of commercial and residential buildings become electricity generators while protecting the inhabitants from the elements.

The solar roof shingles are designed to blend in with the conventional shingles in the context of texture and surface. They are 219.71 cm long and 30.48 cm broad and can be nailed into place on the roof over 130 pound felt sheeting. There are 12 inches long electrical wires which extend from the underside and go through the felt into the interior roof connections.

After the solar shingles are place the heat of the sun seals them in place, known as the weather resistant seal. The size of the array can be varied according to the energy requirement. These shingles can produce 30% of a home’s energy requirements. These are useful in remote areas which are not connected to the electricity grid, therefore they are known as stand-alone. These are a good backup to compensate for blackouts and they can also be connected to the electric grid that excess electricity can be diverted to the grid for others to us. These solar roof shingles come with a 20 year warranty and they are hail resistant. In full sunlight they produce 120 watts of DC electricity. An array can be anywhere from 8 to 40 shingles and generate anywhere from 480 to 4000 watt of electricity in full sunshine. This would total to a good 580 kWh/month.

They can withstand winds up to 125 miles per hour. An inverter is a necessity as the electricity is made in DC and has to be converted into AC for the appliances to use. A battery bank of 40kWh is a good as a back up to store the power to compensate in the event of a blackout thereby allowing an uninterrupted power supply. It can be recharged everyday as the sun shines and its potential energy gets stored. The solar roof shingles can be fixed on the roof unlike the solar panels which have to be places on a rack on the roof or backyard, they are aesthetically pleasing too. It is a logical to pick the solar shingles over the regular ones and solar panels as they give a two in one benefit of roofing and clean energy. These PV shingles are purple or dark blue in color made of polycrystalline single solar cells, they are fitted with a P-N junction diode which converts light into electricity. The solar roof shingles come are a viable option as they not only provide us with free energy. Their cost is met within the first 2-3 years of installation and it is pollution free source of unlimited energy for the next 25to 30 years.

Solar power electricity is the electricity from sun. The sun is an abundant source of light energy or ‘photo’ energy on earth. This photo energy gets converted to electrical energy in certain chemical compounds. These chemicals (mostly oxides), possess a certain physical characteristic that makes this phenomenon possible. This distinct physical property is known by the name of semi conduction and the electricity thus produced is known as ‘photo’ electricity. It is also otherwise called solar power electricity.

The special devices employed for this purpose are called photo electric cells. Semiconducting compounds like crystalline silicate, amorphous silicate and gallium arsenate are used in the manufacture of modules of photoelectric cells. Amorphous silicate or A-Si is considered more effective than its crystalline counterpart and is mostly used in the commercial photo voltaic modules. The Arsenate photo voltaic cells are different from their silica counterparts. Instead of semi conduction, the arsenate cells use a process called molecular beam epitaxy to manufacture direct current. Solar power electricity has found extensive application in widespread fields like fuelling of rockets, plant research, military applications and daily household utilities.

Besides the commercial panels, solar cells can be made in home by using a simple copper plate. The semi conducting property of red cuprous oxide of copper is utilized for the purpose. Copper actually has two oxides. One is the non-photoelectric black cupric oxide. And, the other one is the aforesaid cuprous one.

A single solar power cell typically consists of a translucent cover glass and a semiconducting material inside it. The sides of the glass are often coated with a non reflective paint. The two surfaces of the semiconductor are the two polarities of the cell. The cells are so arranged that they receive maximum exposure to sunlight. Whatever the technology of the solar cells are, be it molecular beam epitaxy or semi conduction, the basic idea behind is always the material’s reaction to photons. And, what is a photon? A photon is the name given to the sub atomic, electromagnetically charged unit of light. Light is actually considered as travelling in bundles of photons.

Many such solar cells can be connected in a series combination to produce a required amount of electricity. The solar power electricity is produced without the burning of any sort of fossil fuel and can be used for all practical purposes.

The direct current thus produced in the cells can be changed to alternating current by a special inverter called grid tie inverter. This direct current is fed directly into the utility grid . an interesting thing to know that the consumer is sometimes entitled to receive a compensation from the utility grid authority for feeding extra electricity in public utility grids. This unique service related to solar power electricity is known as ‘back metering’.

Build solar panels at home in these simple steps. Every day the cost of living goes higher not only by prices of things but by what it is costing our environment in the form of the green house gases power generation causes, and the carbon foot print all of us leave behind. How about using a free source of energy, gifted to us by nature? A source we have been foolishly ignoring!

Build solar panels in your own backyard, just follow these instructions take time this weekend and build the best thing you ever built for your home! You will require a few 16 volt solar panels, a small rechargeable 12 volt acid or lead deep-cell battery meant for continuous use. A battery box; this offers protection to your kids and safeguards the battery.

You will need a DC meter which should match the DC voltage and also the voltage of your battery. The other things you will require are an Inverter and a drill. Build solar panels and connect them to the power sources around your house this will make you independent of the grid generated energy.

You will require AC power to run your appliances therefore you need the inverter. Use the drill to fix the meter and DC input at the top of the battery box. Now use some insulated wire to connect this meter with the battery.

Now connect a wire to the negative input then connect the DC inlet, the solar panel and the battery. You are set and ready to convert solar energy into electrical energy. Now close the lid and place the entire assembly into the sun.

Leave it in the sun for around 8 hours of direct sunlight; you are ready to use solar generated electricity! The benefit of solar panels is that they can be placed anywhere on the roof outside and even on tree tops! Build solar panels for your home as these are more energy efficient than other power sources, as you save up to 80% on your monthly electricity bill. If you manage to totally eliminate your power bill, in some states and countries the power companies PAY YOU for any extra energy you generate and send their way!

You can run all the appliances you want and not feel guilty about the huge stress you are putting on the national electricity grid. Build solar panels and you will save a lot of money if you have a lot of appliances in your home or business like laptops and computers in your small yet flourishing travel agency business or an electronic goods shop. Today hydrothermal projects, nuclear power plants, and hydroelectric power stations generate electricity for all our purposes.

But they are harming the environment as hydrothermal projects heat the water using coal, which when burnt produces ash as residue and gives off heat, carbon dioxide, carbon monoxide and sulphur dioxide into the atmosphere. Carbon dioxide and sulphur dioxide mix with the water vapour in the air and form what is known as Acid Rain. This Acid Rain causes damage to our building and other structures leaching color out of them, making them weak and brittle.

It is also affecting the pH of our lakes and water bodies causing extinction of sensitive species. The carbon dioxide also causes global warming leading to rise in temperatures around the globe. This rise in temperatures is weakening the glaciers by melting unevenly, presenting a safety hazard and even raising the sea levels which will soon submerge the coastal cities of the world.

You may have been discouraged by the information about the cost of solar energy floating around on the Internet and other sources. Let’s have a closer look at these figures to help you decide if it is too costly, and how you can save BIG. You will be convinced that you should get off the grid and install your own electricity producing system. This will free you of the rate of inflation and the rate at which the power company keeps increasing the bill by almost 6% every year (when incomes are NOT increasing by this rate!). By installing the solar electric system you will no longer pay these companies.

Total your previous electric bill and check the cost of solar energy kit for your home. You will be thrilled to see that it is cheaper indeed! You help save the environment (big one!), you save money (important!!!) and it is a very liberating experience to being good to the earth. Advanced technology has helped reduce the cost of solar energy by 7 times. The major reason being the basic law of economics, as the demand increases the cost of production decreases.

As more and more people join this revolution; the cost of solar energy falls. For example, more that 80% of Spain’s energy requirements are met by solar energy. As the market grows, the cost of this clean energy declines further. Realizing the benefits of this energy the government has introduced benefits and incentives. The concept of Net-metering has been introduced, where you get paid to divert the excess electricity to the national grid for others in the community to use. That’s right; the electric power suppliers will begin to PAY YOU once you start living off the grid!

You will have an added passive source of income which works for you silently without much effort from your side besides just keeping the system well maintained; otherwise the components use have a life of 25 years and more with a onetime investment. The cost of solar energy depends on the size of your house, the usage of electricity, the kind of solar energy generator used, the amount of insolation you receive and the government funding to pay you for the energy you generate. A photovoltaic system will cost anywhere from 8000-10,000 USD for a 1kilowatt system which works out to 8-10$ per watt. A hot water system will cost around 2000-4000 USD.  Consider you are living in a 3 bedroom house and you consume 3 kilowatts of energy, to make such a system it will cost you $24,000 to 30,000 without rebates.

BUT YOU CAN SAVE THOUSANDS OF DOLLARS BY BUILDING YOUR OWN SOLAR AND WIND GENERATORS FOR A FEW HUNDRED DOLLARS! CLICK HERE FOR THE STEP-BY-STEP GUIDE NOW!!!!!

Let us consider an example from the state of California, generating a bill of $75 per month. And if you need a 3 kilowatt system the cost of installation will be 24,000. Less government rebate = $7000. Less tax credit = $1,163. The entire cost of installation falls to $15837 only! With Net metering you can save even more. For a 3 kW system = 3000 watt x $2.80 per watt rebate = $8,400. With a 7.5% of system cost after rebate 24,000 – $ 8,400 x 7.5% = 1,163. Basically add 0.5 to the size of your system for each additional 25 dollars on your bill and 4500 USD for the incentive cost. These figures are meant to give you an estimate of your benefits which will outweigh the cost of solar energy generation.

Homemade solar cells require the following materials.  A copper sheet, a clear Plexiglass sheet, a thin wood strip, emery cloth, some copper wire, some duct tape, table salt, a metal guillotine, a band saw and an electric hotplate. To begin with cut out a 6×6 inch square of copper sheet with the help of your metal guillotine, otherwise a tin snip should work.

Now wash the copper sheet and your hands of all the grease and other contaminants well, and dry both well. Take a piece of emery cloth and polish both sides of the copper plate off the oxide and other tarnish until the bright and clean copper shines through. Then to make your homemade solar cells, place this copper plate on the electric hob and turn it up to the maximum power.

Well, didn’t we just remove all the oxide off the plate and now we are heating it to make more oxide? Yes, we will heat it to make cuprous oxide, which is a black color oxide of copper formed when it is heated at a high temperature. Now that you have placed the copper sheet on top of the hob you will see that various patina begin to appear on the plate like oranges, purples which glide and change shapes like live things on the copper plate.

Enjoy this show for a while and also if you are doing this in a lab then get some nitric acid and remove the cupric oxide layer by washing or swabbing with it. After half an hour to 45 minutes you will see a black crusty layer beginning to form on the copper plate: a precursor to your homemade solar cells! You will see a few more color changes underneath and it will continue to heat.

This black layer will have thickened further, now it is time to switch off the hob. Let it cool for half an hour. As the copper plate cools it shrinks, and the cuprous oxide layer crackles and begins to separate from the plate.

Knock the side of this plate on a hard surface and you will see the crackled cuprous oxide fall to the surface. Now put this plate under running water and rub gently with your finger, let whatever washes off flow away and let what remains on the plate be there as the plate beneath has become thinner and fragile. Beneath this layer of black cuprous oxide is a reddish orange layer of copper which is photosensitive.

This is what works as an electrode for your homemade solar cells. The wooden strip is used to make a spacer; using duct tape is best as it is made of plastic which is a bad conductor of electricity. The other electrode should not touch our oxidized copper plate and allow the sunlight to fall on it.

The thick copper wire serves as the second electrode, but if you like you can even use the remaining piece of the copper plate too. The electrolyte used is salt water which conducts electricity from one electrode to the other. Cover this arrangement with a plexiglass lid and connect the wires of the electrodes into a voltmeter and place in the sun. You will see the voltmeter needle jump to 20 to 40 volts as your homemade solar cells come alive!

Wondering how to build a solar panel? Here are the instructions to make one and you will require (very) basic carpentry skills, a few tools and some supplies. These can be easily found at the local hardware store or online. The Tools and supplies required will be: a saw for cutting, plywood, a soldering-iron gun, a paint brush, a resin flux pen, a wire cutter, a screwdriver, a caulking gun, a volt meter, a plexi-glass cutter and a drill.

Note: This article is just a basic guide. For a complete and more detailed set of instructions, visit:

The other parts required are plywood sheets, Plexiglass, some tin wire, some solder, some silicone caulk, a jar of UV-ray protective varnish and solar cells. This is how to build a solar panel, as 80 solar cells will produce around 100 watts of electricity.  Check the voltage of each of these cells and enlist the individual solar cell’s voltage. This will help you to decide how many cells to use, if you want to charge 20 volts battery you will require 40 solar cells which produce 0.5 volts each.

This calculation is to determine a place which receives adequate amounts of sunlight, but if it is a cloudy or a shady place you will need more cells. Cut the plywood to the dimensions of the panel size you want, which means align the number of solar cells you want in your panel, mark the area and then cut it. The panel can be any shape as the cells can be cut into the desired shape. Next, paint on the UV protection varnish and set aside to dry.

Further in the instructions on how to build a solar panel, apply the rosin flux to the back side or the bus strips of the solar cells. This is done to ensure that the tab ribbons solder well to your solar cells, ensuring correct wiring. Then connect the solar cells to each other through the two wires attached; you could make a parallel or a series connection. After this has been done fix these solar panels to the plywood sheet you have just cut and painted.

The two wires, one at the beginning of the solar cells series you just made and the other at the end need to be passed to the back of the panel board through a hole drilled in the plywood board. Now fix these wires in the holes with silicon so that the wires don’t move. Then make a frame for the panel with the see-through plexi-glass and fit it on top of the solar panel you just made and secure it well by screwing and applying silicon. Make sure that your frame is water proof by using silicon, wood screws and plywood if necessary.

Lastly in this (hopefully!) helpful how to build a solar panel guide, seal all the sides of the panel with silicon as you do not want moisture to get in there – after all, it is electrical work! To further ensure that no moisture gathers inside the panel, sand it and drill a hole at its bottom well away from all the wirings. This will allow an outlet to the accumulated moisture and keep the rain out of the panel too.

Maybe you are staying in an RV or a boat? Maybe, you are worried that the summer cooling expenditure is getting more every year? Perhaps you simply want to be prepared for a power cut? Why not build your own solar panels and get rid of all the problems in a nature friendly, clean energy way? That’s a real good decision, sure. Just make sure that you have done your homework properly.

Build your own solar panel from cuprous oxide instead of silicon as it displays photoelectric effect, which cause light to flow through the material when exposed to sunlight. The materials you will require are a half a square foot of copper metal sheet, two alligator clips, a micrometer to read 10-50 microamperes, even LCD multi-meters will do. You need an electric stove with a coil of 1100 watts also called a hotplate. Get a large 2 liter bottle of clear plastic and cut the top, 2 table spoons of table salt and tap water, some sand paper and metal shears to cut your copper sheet. Cut the copper sheet to the size of the burner of the hotplate, and then wash your hands and the metal sheet of all the grease if any.

To Build your own solar panel, polish the copper sheet to clear it of any oxides and sulphides and expose the pure shining metal underneath with the sand paper, you could also use the wire-mesh drill to speed up the process. Now place this polished sheet on the hotplate and set to the highest setting. You will see hues of orange; red and purple begin to appear on the plate as the oxidation patterns; the copper plate gets hotter and these colors oxidize into a black coat of cupric oxide. Continue heating the plate gets hotter and the black coat thickens and there is a layer of red, orange, pink and purple underneath. These colors disappear and the hotplate is glowing red now. Leave this setting for half an hour and allow the black coat to thicken.

Now turn off the burner, leave the copper plate on the burner and let it cool slowly. It is necessary to let the copper plate cool slowly as this causes the black layer of cuprous oxide to flake away slowly as the copper metal cools slowly it shrinks. As the copper plate cools the flakes pop off while the plate cools, it takes about 20 minutes for the plate to cool down completely. Now take the plate to the tap and place it under running water, and scrub the plate lightly and the flakes will come off in bits.  Do not scrub hard or flex the plate as this will damage the red cuprous oxide needed build your own solar panel.

Now take the other half of the copper plate to build your own solar panel. Now bend both the cupper plates and fit them into the plastic bottle, they should not touch each other. The upper surface of the plate you heated should face outwards from inside the bottle, this is the cleanest surface. No attach one alligator clip to each of the plates. The other lead from the unheated but clean copper plate is linked to the positive terminal of the micrometer.

The lead from the cuprous oxide plate is linked to the negative terminal. Now mix the two tablespoons of salt hot tap water, until completely dissolved. Pour this water into the jar taking care that the alligator pins do not get wet, also fill the container leaving an inch at the top. You were assembling this device in the shade therefore the needle of the micrometer displays zero. Move it into sunlight, you will see the needle leap to about 30 micro amperes.
