Electricity?

Question

is there cost effective way to store up the electricity or energy generated by a solar cell in the day and use it at night? can you explain it thanks

Answer 1

The best way is to use rechargeable batteries -- essentially automobile batteries.

There are whole solar power systems that you can buy that have the solar cells, the batteries (a minimum of 10, but usually at least 24), and e control/electronics box called an inverter that automatically charges the batteries during the day, and switches over to use the batteries at night.

Alternatively, some people have suggested, or even experimented with using large spinning flywheels to store the energy. The flywheels would build up speed during the day and the energy could be taken from them at night (slowing them down).

Answer 2

If you are in a location where you can connect to the grid, find out if your local utility offers net metering.

When you have solar output, it slows your meter down or even runs it backwards. When your house draws more than the solar system generates, you draw from the utility like you normally would.

This allows you to use the utility for your battery! This also allows you to start small and add on to your system as you have funds.

Answer 3

Or you can use a pump to pull up water into a elavated tank. and then turbine it back down wnen needed. This method can be cheapest in terms of $/watts.
