How does a solar powered home stay powered when its raining?

i know its a stupid question, but explain please

Because the solar power charges up a battery that can last for a very long period of time, so at night time, when its raining or during solar eclipses you still have power

    A grid-tied home will just have solar assist, so will run off the grid like any other house, same as it does at night.

    An off-grid home will have batteries. For periods of prolonged darkness, they will typically go to a gas-powered generator.

    I’ve found http://renewenergysources.blogspot.com/ is a great blog with some links to ways to use solar energy in your home.

    I have solar direct powered fan for my seat in my hall. It is working well from 7.30 AM.to 5 P.M on all days. To get higher efficiency I am not storing the energy in battery.But even if it is raining if the clouds are not affecting the radiation of sun lights it works well.The alternative method is storing the solar energy in battery cells and use it when it is cloudy.

    the home solar power system have two type:
    grie-tied solar power system or called on-grid system,
    and stand-alone solar power system.

    the on-grid system produce electricity when there is sunshine, and feed the extra electricity to the national grid, when there is no sunshine at night or raining, the house could get electricity from the national grid, so on-grid solar power system always have to meters, one is for selling electricity and the other one is for buying electricity.

    for the stand-alone solar power system, the electricity produced by solar panel will charge into a battery system, because the voltage and current from the solar panel is unstable according the sun irradiation, so we need to charge into battery. But still, the electricity from battery is in DC, so we need a dc to ac inverter to produce AC 110V or 220V for our home appliance.

    So the batteries will be charged in the sunny day, and could use in the night and raining days.
