How much does it cost to put up solar panels for a school?

Question

the school's roof is 240 meters.

Answer 1

Solar panels typically cost between $7 and $10 per watt.   And you usuallly get about  125 to 150 watts per square meter.

So assuming that we could use 80% of your schools roof, it would produce roughly 30kW (at peak performance) and would cost about a quarter of a million dollars, US.  Assuming that you get 4 peak hours of sun per day (which is roughly average for the US) and your electricity cost 12 cents a kWh, you'll save about $5,200 per year.  

These numbers are very very rough, but they should give you a place to start.  Hope this helps.

Answer 2

dont know. I know it would cost 10k to put them on our house..But in the long run it does save money..

Answer 3

Probably upwards of about $50,000-80,000 installed.

Answer 4

The same as for anything else: about $10 per watt of installed capacity.  Since a solar panel can produce AT MOST two kWh per year per watt of installed capacity, which is worth about 25 cents, it makes economic sense to install them only if a huge subsidy is available -- which doesn't make them any more sensible -- it just spreads the pain out over a larger base.
