solar panel to run AC in the summer?

We Answered:

I use two window A/C units and I have a 1600 SQ home. It may not be as hot here as it is at your place but works great for me.

You can run a 5000 BTU A/C unit that you buy at Freds department stores on about 800 watts of solar modules. A 5000 BTU A/C uses about 6 amps at 120 volts running hard. 120 volts times 6 amps = 720 Watts. So you might want to say 850 watts in panels for heat losses.

So about $10,000 to $15,000 depending on where you are and who you are dealing with.

If i buy a 5kw solar panel and i use 370gw how many solar panels do i need?

We Answered:

watts and kW and MW and GW are units of power, not energy.

A 5 kW panel will produce 5 kW as long as it has bright sunlight, there is no time limit.

case is important in technical terms. Is 370gw actually 370 GW, Giga watts? That is more power than the entire US develops.

watts per year is meaningless, watts are already are per time. 1 watt is 1 joule per second. Or 1 watt-hour per hour. Joules or watt-hours or kW-hours are units of energy, whereas watts or kW or MW or GW are units of power.


edit:
If you mean 370 MW-hrs (not the same as 370 MW)

370 MW-hr in a year is
370 MW-hr / 365*24 = 42 kW continuous power for that year. So if the sun is shining continuously, which it is not, you will need 42/5 or 9 panels.

If you can count on 8 hours of sun per day, then you need 26 panels.

What Is Solar panel & Where Can I Buy It?

We Answered:

It's a pane of glass/silicon/other things that converts solar energy into electrical energy. You can buy a low power kit at harbor freight, but you'll still need a 12V battery (Car batteries work well) and some sort of inverter.
