Standard solar panels cost around 65 to 75 cents per watt.
Having a solar setup this size pretty much removes the need for a generator though you might still want to have one on hand for emergencies.
The second technology is concentrating solar power or csp.
How much energy does a solar panel produce.
For the sake of example if you are getting 5 hours of direct sunlight per day in a sunny state like california you can calculate your solar panel output this way.
The tax break reduces the.
Thus the output for each solar panel in your array would.
Assuming we get 5 hours of direct sunlight we know a 100 watt solar panel will produce 30 amp hours per day.
Solar installers consider the following factors to calculate the number of panels needed.

Solar companies can typically get a single solar panel at a price of 0 75 per watt.
That panel is rated at 100 watts at peak efficiency meaning on a 78 degree cloudless day at solar noon on the equator during the equinox.
A system like this will cost around 4 700 5 700 total.
This includes all installation components.
A 100 watt solar panel produces approximately 6 amps per hour in direct summer sun without clouds.
For our experiment 5 hours of direct sunlight without clouds x 6 amps generated per hour 30 amp hours per day that the solar panels are generating to.
