Let s say you could achieve an overall solar array conversion efficiency of 20 and you want to generate 1 2kw of power to run a space heater.
Run space heater off solar panel.
So the total sun power hitting your photocells times 20 is the amount of electrical power your photocells will generate which needs to be 1 2kw.
Over the course of a sunny day this system can heat a room at zero cost.
It s a question that comes up often for those looking into smaller scale solar installations.
Or a third option would be to convert a traditional electric space heater to solar by plugging it into a portable solar panel.

1500 watts is beyond the capability range of a 100w and 200w solar panel however it will work with a 300w panel.
And it is really great that you re thinking of using solar.
