Residential solar power

A residential solar power system is a device that can cost thousands of dollars to install. Although these systems promise to save money over the long run, it could be more (or less) than a decade before a person sees a return on the investment.

There are three main types of residential solar power systems:
• Real-time solar power – These residential solar power systems work only when the sun is shining. They collect UV rays from the Sun, but don’t do much with it after it is collected. This is a good source of energy during the day when the sun is shining, but once the sun goes down, this energy source is no longer useful.
• Battery – This is a financially sound residential solar power purchase, but initial costs may make the buyer think otherwise. These are useful systems because the energy collected does not need to be utilized immediately and is moved into a battery. This creates a reserve of energy throughout the night, even when the sun is not shining.
• Grid – Some people use a tie-in to the local power grid to “sell” their excess residential solar power. You can actually watch your meter turn backwards in as the energy is taken from your home cells and transferred to the local power grid.
