Question

Can you store solar energy to use at night or on a cloudy day?

Answer 1

yes connect a lead rechargable battery to the circuit

or in the modern form, an electrical UPS or invertor

Answer 2

Solar electricity is already a DC current and can be stored directly in a battery.  

Alternately a guy recently set up his house to use excess solar power to electrolyze water and store the hydrogen, which is put through a hydrogen fuel cell to generate power when the sun isn't shining.

Solar heat can be stored in any sufficient mass and released when needed.  Usually water is very good for this purpose, but any large mass will work.

If you think about it the earth itself is a large thermal storage device it collects heat all day and releases it at night which is why it is usually cooler in the evenings and morning.

Answer 3

There is new technology that allows you store it, however, companies like Texaco have bought those patents and controlling shares in those companies and are preventing them from being available to the consumer.  No this is not rumor, this is fact. Check the source below.
