The prices of electricity have been increasing drastically and you can simply compare your last electrical bill with that of 5 years ago. Instead of searching for a new source of energy, let's think about reducing our electrical bills. A lot of times this possibility isn't taken into consideration, but wouldn't you be happy if you can save over 80% of your actual bill for all the next electrical bills?

All you need to do is to learn how to build a solar panel to produce your own electrical energy through solar panels. These solar panels take and keep the energy from the sun and turn it into usable electrical energy that we can use every day in our ordinary lives. Generally, the majority of people that know about solar panels think that they won't benefit from its use as they just work in sunny areas. That isn’t the case. In fact, the new generation of solar panels can produce a lot of electrical energy even on rainy weathers.

Building your own home solar power systems is very easy: first they need to be installed (most of the time, on the roof of homes) and then they take the energy from the rays of sunshine and convert it from solar energy to electrical energy.

Solar panels must be kept away from shading, as shaded cells draw energy for themselves from other cells.

Things you need to know:

1. Solar panels using monocrystalline cells have high conversion efficiency, and take up less space, but lack shade protection.

2. Solar panels using polycrystalline cells have even higher conversion efficiency, take up even less space, but still lack shade protection.

3. Solar panels using amorphous silicon cells have lower conversion efficiency, and take up more space, but do have shade protection. This can be specially important on a sailboat.

Once you have determined the size and number of solar panels needed, you will be better able to determine where they will be placed. The best places depend on the roof’s length and size of the panels. Take your time and think it through.

The simple answer to how to build a solar panel is none other than the sun. Select locations that will get maximum sunlight without shaded spots.

In placing solar panels, take into consideration the use of extra bars/braces to secure the panels. You obviously want them to remain stable.
