How to Build a Solar Panel
Learning how to build a solar panel is not as difficult as you might imagine. But, is it worth it ? I would say it is if you want to save money on power and want to become more eco friendly and support the environment. There are a few manuals on this subject area, but the most helpful I have found about how to build a solar panel is the earth for energy guide.
Did you know that solar panel installation by professionals can set you back $20,000 or more ! Well, how would you like to build one for around $100 each !
Is it Easy ?
Yes, it is – learning how to build a solar panel is not hard to do with the detailed instruction manual with pictures and all the info you will ever need. Plus they give you a video series as well, to fully reinforce how to do everything.
Earth 4 Energy found 43 people (male and female) who were interested in solar but knew nothing about making panels, and they gave them our guide and came back in a month to see what they have built.
All 43 of the “solar newbies” were able to create a well polished solar panel that generated enough electricity to run some household appliances!
Anybody can do this. Male, female and from any age group. This is a great opportunity to save money and go green at the same time.
Is the package expensive ? No, not at all, although my guess is that the price may go up in the future when they figure this out. Save money, support the environment. I think you will be pleasantly surprised with what you find here, like I was..
How to Build a Solar Panel | Background Information
The sun is one of the most abundant, if not the greatest, source of energy that people can harness and tap into. Learning how to build solar power for home, business, or commercial purposes is a major step in utilizing a power supply that experts predict will be going strong for approximately four billion years from the present.
Photovoltaics is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of cells containing a photovoltaic material (e.g. monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride).
There is an important factor to consider if you are interested in knowing how to build a solar panel. This factor is location. Determining your location is important in order for you to decide where the solar panels should be placed or not placed. For people who reside in the northern hemisphere, their solar panels should be constructed facing the south.
This placement is for the panels to capture as much sunlight as possible during the day. For people who reside in the southern hemisphere, on the other hand, their solar panels should be constructed facing the north. This placement ensures that the panels catch the maximum quantity of sunlight every day.
It is common for people who want to learn how to build their own solar panel to get intimidated, but this need not be the case. As long as you are equipped with basic skills in carpentry and a good sense of direction, then there should be no problem. As with any activity, it is important to make a list of the tools and equipment needed before you begin. Here is a list of the tools and equipment needed in building a solar panel:
How to Build a Solar Panel – Tools needed :
-Soldering iron gun
-Rosin flux pen
How to Build a Solar Panel – Equipment required :
-UV-ray protective varnish
How to Build a Solar Panel | Solar Cells
When buying solar cells, it is helpful to bear in mind that eighty cells normally produce one hundred watts of electrical power. The solar cells need to be tested individually, and for this purpose, the voltmeter comes in handy. Make a record of each solar cell and the amount of voltage it produces.
Next, make an estimate of the amount of power needed from each solar panel that will be constructed. Areas that do not receive a sufficient quantity of direct sunlight need more solar cells than their well-lit counterparts. Determine these qualitative measurements. Then take a piece of plywood and mold the dimensions of the plywood according to the number of solar cells that are expected to be on the solar panel. Make sure the plywood is large enough.
It is common to see rectangular-shaped solar panels that are mounted in homes. However, if you are not up to the idea of having a rectangular solar panel, then you do not have to conform to that shape. One advantage of learning how to build a solar panel is that you get the privilege to shape the panel according to how you see it fit.
Using the paintbrush, coat the freshly cut plywood with the UV-ray protective varnish. To save time, begin working on the solar cells. Start by applying flux to the bus strips found on the solar cells. Use the rosin flux pen to accomplish this. This process is to make sure the tab ribbons and solar cells adhere completely when soldered together, and this also ensures the wiring is correctly connected. The solar cells are then connected to each other.
After all the solar cells needed for the panel have been connected, fasten them snugly to the panel of plywood. Use as little silicon as possible. Then make two holes by drilling in the plywood and insert the two hanging wires from the solar cells into them. Once this is done, seal off the gaps with silicon.
The solar cells must be covered with Plexiglas, so a frame for the panel is needed. Attach the frame to the panel to the plywood using silicon and wood screws to ensure that the construction is waterproof. Then drill holes into the Plexiglas, then attach it to the frame by using silicon and screws. Note that the drilling needs to be done first to prevent the Plexiglas from cracking.
Check every inch of the solar panel for holes and gaps that could permit moisture to seep in, and seal every hole with silicon. However, since there is still a tendency for moisture to gather in the interior of the solar panel, it is helpful to drill a tiny hole at the bottom. Make sure the hole is placed far from the wires.
See, learning how to build a solar panel isn’t so hard after all!
