Here is a way that a residential house could effectively store solar energy during the five hours of good sunshine, to last for the full twenty-four hours. Use a hydraulic elevator system lifting a very heavy weight, where the energy is stored by the gravity of the weight. When the sun goes down,or when more power is needed during the five hours of good sunshine, the very heavy weight movement is reversed and the hydraulics is used to generate power.

In order to have a tv-set (~100W) working for a hour, you would need a 36 tons weight (which I guess is a very heavy weight, about the weight of a boeing 737) to be moved down by gravity of one metre. Now think about a washing machine cycle, which takes 10 times the energy of the example above…Unfortunatly there are few ways to store electricity, and these ways are repumping water in order to fill an artificial lake made by a dam, generating hydrogen or use a lot of batteries.
