The 6th video of the Green DIY Energy “Build your own solar panel for less than $100” is the last video in the series. In this video, the host Bryan Clark will show you the final testing of a Do It Yourself (DIY) solar panel.
The finished homemade solar panel as per the instructional video is a 36 Photovoltaic (PV) cells that is capable of generating 75 watts of electricity.
All of the cells are wired in series therefore it is producing about 18 volts nominal. An 18V solar panel is capable of charging a 12 volt deep cycle battery.
When you are doing the final testing on the solar panel, make sure the sun is out and there are not too many clouds in the sky. Any shadow casts on the solar cells will affect its power output.
Using The Multi-meter
To do your testing, you have to bring out your multi-meter. Set the dial to measure voltage. Touch the testing rods on the positive and negative run wires coming out from the back other solar module. The reading should show around 18V.
When you’ve done that, reset the dial to check for the current. The amperage from the cells should be around 2.5 – 3 amps.
Utilizing Power From Solar Panel
When you are creating electricity from a solar panel, the output will be in Direct Current (DC).
Since most of our home electrical appliances such as computer, television, refrigerator, microwave oven etc run on Alternate Current (AC), you will need to connect the output from the batter to a power inverter. The power inverter will change the DC into AC.
Finally, you can use the power from the inverter coming out of a standard 120V plug.
Scaling Up The Solar System
Now that you know how to make a solar panel for under $100, you can start to scale up the project. All you have to do is repeat the process and start work on the second solar panel.
If you have electrical appliances running on higher voltage, you have to connect multiple solar panels in series to up the voltage.
If you want to charge a battery quicker, you can actually wire the solar panel in parallel to increase the amps. If you double the amps, you literally can reduce the battery charging time by half.
If you want to know more on how to make a solar panel under $100, make sure to check out the Green DIY Energy program. Apart from the High Definition (HD) instructional videos, it comes also with a good selection of e-books on DIY solar module and homemade wind generator.
