Pool Solar Lights

Randall Said:

what will be the best energy power for a complete house if i want to be energy independent from the electric?

We Answered:

an inverter changes power from one voltage to another......like the 12 volts in a battery charged by a solar panel to 110 volt for use in a house.

IT is not a power source.

Figure out how much power you need........I run a 75 unit condo complex in the sunny, trade winds Caribbean. We would need about 9,000 kWh a unit a year to go "off the grid".

So figure your house you are talking about would need more, because I assume you have to heat it in winter and cool it in summer. Call it 10,000kWh.

A wind generator that puts out 2,000 kWh a year costs about $7,000. Thats in 14 mph winds. In 10 mph, 24/7 it puts out barley 500.

A bank of panels which would average out to 1000 kWh a year ..(10 hours of light a day over the year ) batteries to store the energy, that old inverter, wires and all that runs about 7 dollars a Watt, or $7,000.

To get my complex off the grid is about 25,000-35,000 EACH apartment.
