PV Gap

Willie Said:

electricty is not available at my form house, How i can generate with solar energy (4 lights, 1 fan, 1 tv)?

We Answered:

4 CFL bulbs at 14 watts each is 56 watts.
My stand up fan only uses 70 watts on high.
My large 36 inch TV only uses 88 watts at max.

Total 162 watts

Lets run them all at the same time for say 6 hours a day. So we need 972 watts per day.

If you get 4 hours of peak sun you would need 243 watts in solar panels and to allow for loses you should get 300 watts.

Now you need batteries to last a day or two. A 100 AH deep cycle battery holds 1200 watts in power and to keep it above 50% discharge you would need two.

The inverter just has to be able to handle the total power usage of 162 watts so a 300 watt inverter would do.

300 watts divided by 12 volts is 25 amps so you need a charge controller that can handle 25 amps


3 each 100 watt solar modules. About anywhere on the net.
1 each 300 watt inverter Walmart or auto parts house.
1 each 30 amp charge controller Xantrex C-35.
2 each trojan t-105 6 volt deep cycle batteries 225 AH.
A couple of breakers from lowes or home depot and you are in business.

Here is a how too page to help you out.

what are examples of solar/light energy 10 points first anwser?

We Answered:

Wind power arises from thermal gradients in our atmosphere from solar heating and hence is solar power.

Wave power are from waves generated by winds blowing across the surface of water and as the winds are from thermal gradients, it too is solar power.

Hydro power arises from the evaporation of water and the subsequent precipitation of the water at a higher elevation and it's flow back to the sea therefore it's solar power.

Biomass are the chemically stored energy collected by photosynthesis from the sun.

Fossil fuels are from the accumulation of biomass over millions of years in geologic formation and hence are also solar power.

Only tidal, geothermal and nuclear are not from the sun. Tidal being from the kinetic energy of the Earth's rotation and the moon's orbit, geothermal is from the heat left over from the formation of the Earth and nuclear being from the decay of unstable elements formed during the death of a star from which our solar system was formed.
