how make my house on solar electricity

Don't even consider it. It's a con.

It's not a con, it's just not worth it. If you have no source of electricity,
no availability of fuel for a generator, or are very rich and don't mind
spending a lot of money with no return on your investment, it's an option.

Wind and water power are much cheaper, but you need to have a source of
almost constant wind or water.

Solar electricity is expensive not only because it requires very expensive
equipment to generate the electricity, it requires a large investment in
batteries to store it. The batteries must be protected from heat and cold,
have relatively short lives, etc.

You also need the Sun which is not easy to get.

The farther north (or south) of the equator you are, the shorter the days
are in the winter, which means less charging time and longer battery drain.
You also loose power on cloudy days, solar heaters don't work well when it
rains, and so on. The collectors need to be cleaned often, a small amount
of dust reduces efficency dramaticaly.

The Sun travels across the sky from east to west at the equator. This means
that fixed arrays only get exposed for a relatively short time. The farther
away from the equator, the path becomes south-east to south-west (or
if you are below the equator, north-east to north-west), but unless you
are very near a pole, it's still a wide transit. Self positioning
solar cell arrays are available, but they are far more expensive,
far more complex and far more prone to damage.

Solar heating is far cheaper and easier than electricity.
