So the question is this: If we need light at night, how do we gather light during the day, store it and then set it free at night. Same goes with heat. Ok, light. One could store light directly via lumenescent materials. Heat, one could store it by heating stones and trapping the heat then realising it slowly at night. The point that I am making is that we are trying to solve the wrong problem; the problem is not how to store electricity; the problem is how to store appropriate energy and release it over time.
There is a system that uses PV cells to electrolyze hydrogen from water.
In a twenty four hour period with a given amount of daylight (not necessarily sunlight) the system creates enough hydrogen to drive a turbine that will supply all the electricity a household would need.

Problem is that the PV cells will cover the roof of the average house (pricey)
