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

Question

company...for example if i have a house with heated pool and

others like fridge , tv, and lots of lights... what would be the best alternative (WINDMILL or INVERTER or SOLAR PANEL) or a combination of all.

Answer 1

Considering how expensive alternative energy systems are, you may want to consider first looking at energy efficiency means and then sizing a solar and/or wind system for your home.

For every $1 you spend on energy efficiency, you will save $4-$5 on alternative energy. Adding things like radiant barriers, better insulation, sealing your home, energy star windows and energy appliances, etc..

Then look into solar and wind if you are in an area that gets enough wind for it to be feasible.

Answer 2

I too suggest to go for combination.

like solar+general electricity

besides have an inverter which is always on the safer side.

Answer 3

i would guess a combination would be best.  the government gives tax breaks and grants for shifting to solar power.

Answer 4

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.
