Do you guys consider Solar energy as free?
It seems that people who have off grid solar power, can use as much electricity as they want during the day, easily running 10kW loads.
Every second house has solar panels in many areas.
I want to say it is free energy, because the energy is coming from the environment, just like a heat pump which gives 4kW of heat for 1kW of input.
But the night time is a problem, so how can we implement the thinking of the heat pump or free cooling to utilize solar panels at night? There must be a opposite of sun light which can be utilized.
A different type of electricity which cannot be measured by the meters. Just think like a Joe Cell which needs only its negative pole connected to work..
