It can be very expensive and takes a long time to see returns. More and more are building their own to keep costs very low.
about 7% od Americans use solar power
It's much easier to use oil and it costs less. When using solar energy. it cost millions to just build it when oil/fossil fuel is easy to mine and use.
10,000 homes in the U.S.A. use Solar power for heating and for some electrical appliances. It cost almost 10,000 a year for one solar panel.
yes, they have a reserve of petrol as a back up but they do not use much as they are solar powered. their main power comes from the solar panels.
There is no general easy answer to how many panels are needed for your exact home. This depends on how much power you use, how much rainfall you receive in your location, and other factors. A solar panel can create 70 milliwatts of power per square inch, so completely changing an average home's power usage to solar would require a solar panel that measures about 285 square feet, or about 26 square meters. This would cost around $16000. Without decreasing your lifestyle's dependency on electricity, powering your home exclusively through solar power is difficult.
Solar Power is an inexhaustible alternative energy source. Because the sun will never run out, we can use solar power for power. And even though solar panels cost a lot, the sun's power is free! However, at night or during long periods of bad weather, we will need another energy source to rely on.
The amount of sunlight available, weather conditions, and the efficiency of solar technology can limit the use of solar energy. Additionally, cost of installation and energy storage can also be limiting factors in widespread adoption of solar power.

alot because there is alot electiricty in the wind power machine but i dont know how much it cost by heart
Some governments use solar energy to power offices. Communication and military satellites are powered by solar cells.
Solar power is generated by an unlimited source of energy called the sun.
