Off Grid System
An off grid system is just that, off grid. It is not hooked up to the electric utility system. There are no power lines running to the house.
Off grid systems require a battery system for back up power and to supply electricity at night. During the day when the sun is shining onto the photovolatic array the excess energy is stored in the batteries. This surplus energy is then converted into electricity and released into the system by the batteries.
A generator is also a common component for the off grid solar power system. If the sun is not shining for several days then the generator can charge the batteries instead of using the sun's power.
Solar power is a long term, renewable energy source. It frees you from dependence on a utility company, frees you from dependence on foreign governments, and frees you from having to write a check every month for electricity. Residential solar power is the wave of the future.

What is Residential Solar Power
Residential solar power is the term given to the electricity that a home owner produces by harnessing the power of the sun.
Grid tied residential solar power is a house that is still tied the electric utility network. You can just think of the electric company as a big back up battery array. When the sun is shining your electric meter will be spinning backwards, net metering. When it is dark or overcast for long stretches of time or you need more electricity than you can produce your meter will spin forward and you will be buying electricity from the utility company.
Each utility company administers it net metering system differently so check with your company for their policies.
