PV Gap

Zachary Said:

I have a mini solar power system setup. Do you think it will work out well?

We Answered:

rig it up to a multi metre and see how fast it charges to full load.

take note on this; assuming if u have a 1000 amp hour ......it is recomended to draw only 10% which is......... 100 amps, if its a 800 amp hour batt.....its 80 amps.....but don t exceed 10% as it shortens battery life
once drawn it has to be replaced asap.

you have not given your batt size....

good book or website on to completely set up a solar power system for a house or an RV or any solar system?

How muchwill it cost to put up a solar power system enough to sustain a 150sqm house?

We Answered:

As the other person told you it all depends on how much electricity you use not how large the house is. I have a cabin which I have a solar system on which is very small and home made--up and running for under $750. BUT--it powers very little, just my computer, fan, lights and water pump.

If you want a "full power house" with everything a 'usual house' has then you won't have enough space on your roof to power everything.

Best bet, figure out what you need and how much electricity it uses then you can go from there. Until you have a budget on how many KWh you need there is no way to get the $$$'s.

How much cost savings could be expected using a solar power system that creates 2100 watts during the sun day?

We Answered:

When someone has a 2100-watt inverter installed, that usually means they're running 1800 watts or so through it, in real life. We can project power generation based on all kinds of assumptions about the panels and your location, but that's unnecessary. The Sunny Boy should have a log on its display of the total power produced. You can just look at that, and see the total number of kWh's produced over the last 2 years, or however long it was actually installed. Then, you can multiply that my the cost of electricity in your area.

Also, ask the homeowner (seller?) how much they think they save per year. It will be nuanced by how much power they use, and whether their electric rates are tiered or not. For example, if they use a lot of electricity, they might be paying a lot, maybe 30 or 50 cents a kWh, for those last few kWh's. If the Sunny Boy is displacing those, then it's saving an awful lot of money.

Lester Said:

How much would it cost to set up a solar power system for my house-I need 11 KWH of energy total for my house.?

We Answered:

Based on the lowest current panel prices of $7 a watt, you would be looking at an initial cost of about $77,000. That initial cost will rise after about ten years as the photovoltaic panels decrease their electricity output by about 10% every ten years.

Seriously, if you want to go green, consider a mixture of both wind and sun. You'll save a massive amount of money by doing so. And consider solar for heating your water, as this is a very effective way to save money.

Here is a link for building your own solar water panels:
