Here's a basic description of how light from the sun is transformed into electricity we can use in our homes, and how it interacts with your utility-supplied power in a grid-tie system.
Solar panels collect the sun's energy and convert it into direct current (DC) electricity. The number of panels you need is determined by your electricity needs.
An inverter converts the electricity from DC to alternating current (AC) for use in your home.
A bi-directional electric meter displays net power usage. When the solar system generates more electricity than you use, your meter will spin backwards. When it generates some electricity, but less than you are using, it spins forward, but more slowly.
You now produce your own electricity to be used throughout the home. Since there are no moving parts, your solar system is silent and virtually maintenance-free. You can track your system's production conveniently from inside your home with a wireless display.
All excess electricity generated is, in effect, stored in the utility grid for your future use.
Renewable Future Energy Resources is committed to providing services to residential housing and commercial applications to reduce carbon footprint while reducing grid power consumption therefore decreasing the need for grid power.
