So how do you get any power when the Sun's not shining? In a word: batteries. Some of the pure sine wave inverter electricity that is generated on sunny days is stored in batteries. This is where you will get electricity to use at night or on cloudy days.
But, the biggest problem for most homeowners is that the cost of a professionally installed solar panel system could cost tens of thousands of dollars. That's a lot of money to pay for solar energy for your home, unless the homeowner takes it upon themselves to build their own solar power system. The technology is there and you can get the items you need at hardware stores and over the internet. In addition, there are many guides that will show you how to do it for a fraction of the cost of a professional installation. There really are no more excuses not to go solar.
Development of solar dc to ac inverter shingles and photovoltaic cells was a major accomplishment in harnessing solar energy. But this was just the beginning as further research will no doubt bring about even smaller and more energy efficient solar panel systems in the years ahead.
