Think about converting your water heater to solar energy. A water heater can represent upwards of thirty-five percent of a single home's energy use. While these costs may be lower upfront than the full power ones, solar water heaters can save you money sooner.
I will show you how to make a Sun filter. Very cheap to make it.
Carefully consider the types of solar panels you plan on having installed. Long ago, if you didn't have enough roof space, you'd need very expensive high efficiency mono-crystalline panels. There are now more advanced polycrystalline panels and even thin film panels. If you've got enough roof space, you might wish to look at the size of the panels in relation to their output capacity to avoid having insufficient panels that you need more of later.
