New Method Allows Anyone To Use Solar Panels At Home
Building solar panels is a fun project that teaches you fundamentals of solar technology and how the suns (photons) energy, is converted to (Electrons) electrical energy. While the price of solar cells range between $20 to $40 per 100 watts, it’s no wonder why countless enthusiast choose to build their own solar panels.
Apart from the obvious benefits of solar power, cheaper solar means more people can use it, which is great news for the environment and bad news for the power company. Building solar panels though, is not for everybody as it can be a technical process and often prone to solar cells being broken in the process.
DIY Home Energy, is the best guide for anyone that wants to build their own solar panels, with the chances of making least mistakes. It’s a little overhyped, but yet it’s a great guide - especially for beginners!
DIY Home Energy
When it comes to building your own panels, DIY Home Energy, makes everything so simple, that anybody that can use a soldering iron, can easily and cheaply build their own solar energy system, making their own electricity and powering their home appliances for free.
DIY Home Energy (or “Do It Yourself” Home Energy) is the step-by-step, easy to follow system that allows you to:
By following DIY Home Energy’s detailed step by step videos you can build your own super cheap solar panels very easily, that generates exactly the asme power as expensive commercial ones. Optionally, you will also be guided on making your own wind turbine and additionally, you will learn how to combine those, into your own energy system, which can then power your home appliances. You can build your solar energy system, as big as you want and even power your entire home, effectively being able to go off grid!
But If by any chance you happen to get stuck at any stage of your project, then there’s no need to worry at all, as there is around the clock technical support for any questions and help if needed - the resources are just fantastic.
This is the best innovation for anyone looking to save money or even getting off the power grid, but most importantly, going green has never been so easy!
How are solar panels made?
Solar panels are made from both passive and composite materials, A 12 volt solar panel is made of 35 solar cells, while a 24 volt panel is made of between 70 (connected in series), which are standard for both 12 and 24 volt panels. Each solar cell generates .5 volt (or half a volt) and the power (watts) is determined by the surface area of that cell.
Solar cells are very fragile and can break very easily during the building of solar panels, which is why it’s so important on the type of soldering iron used to weld the wires to the cells and as well as the temperature of the iron - which should be 360˚ Celsius or more - also important is the jig used to evenly (space) line up the cells, before welding (soldering) them together in series.
The wires that is used to connect the cell is tabbing wire, while the wires used to connect to the tabbing wire is bus wire - Bus wire is about 2 1/2 times the width of tab wire.
2 short lengths of tabbing wire is welded to the positive electrodes of the solar cell. This is repeated for 35 to 70 cells, depending on the panel voltage being built. For a 12 volt solar panel, 5 groups of 7 cells each are welded in series and then later, the 5 groups is welded in series with bus wire. Each group is connected as follows: the positive tabs from one cell, is welded to the negative electrode of the next cell. This is repeated for 7 cells.
5 groups (A, B,C,D and E) of those is made.
When the 7 cells (group A) are connected, 2 tab wires is welded to the end of the last cell, which is the negative electrode. This is repeated for group A, through to group E.
Finally, bus wire is welded to connect the groups in series. The tab wire from the positive to the negative are your terminals. With a volt meter, the total voltage should display 19 - 20 volts in peak sunlight.
The final stages involves permanently sealing the solar cell array, in a laminate similar to the ones used on car windscreens, which is namely, EVA.
A backing and tempered glass is used for the final stages. The backing has 2 small holes for which the terminals are passed through and then finally the terminals are welded to solid terminals, which is then inclosed inside a junction box. A blocking diode is soldered to the positive terminal before the final connection. The blocking diode prevents reverse charge of the solar panel.
The cost of building a solar panel can range from just a few bucks, to a little under $100.00, depending on the hardware used to seal the cells.
Good luck and happy DIYing solar energy!
