This solar power calculator will, given the Watt rating of a solar panel, your location and your grid cost of electricity produce a table indicating the solar powered energy you can expect to generate in Winter and Summer, along with the yearly average and equivalent cost of supplying the same electricity from the grid (or if your government operates a 'gross' feed-in tariff, put that in amount to see how much you get paid). You can use this information to calculate the expected rate of return and the number of solar panels you need for a given power load.
Remember, the values calculated here for solar power production should be taken as a rough guide, it does not take into account other effects (like cloud cover, transmissions losses, building and tree shading, etc). It should be considered a best case figure.
Reset & do another solar power calculation.

Hello,
I am writing a research paper to estimate the PV array power output.
Can you provide me the specs of a few of your panels and an equation to calculate the power output.
I am located in Cupertino, California.
Thanks & Regards

Can you calculate the capacity of solar panel needed to charge 12v 200Amp/h battery in 6hrs. I have 125 Watt solar panel so can it be charge my battery fully?
Thanks,
Martin

we are from India w'd like to have a 40kv solar pv system with 20 kv actual load and + 20kv to charge battery (will be used when power is not there during nights and cloudy wheather)ie 6-8 hrs solar charge and 16-18hrs battery supply.Kindly request help in assessing no of panels polysilicon 200w peak or 140w thin film modules and battery capacity to be provided.
