People use solar energy because it is a renewable and sustainable source of power that is environmentally friendly, reduces reliance on fossil fuels, and can help lower electricity bills in the long run. Additionally, using solar energy can contribute to reducing carbon emissions and fighting climate change.
Unused solar power in a grid-tied system can either be exported back to the grid or stored in batteries for later use. In off-grid systems, excess solar power is stored in batteries for use when the sun is not shining. Additionally, some solar power can be wasted if it cannot be stored or exported.
Some disadvantages of using solar power include its intermittent nature (dependent on sunlight), high upfront costs for installation, and the need for large space for solar panels. Additionally, energy storage solutions are required for consistent power supply when sunlight is not available.
The modern development of solar power can be traced back to the 19th century with the discovery of the photovoltaic effect in 1839 by Edmond Becquerel. However, practical applications of solar power for generating electricity began in the mid-20th century with the development of the first silicon solar cell in 1954 by Bell Labs.

A very small number of people just use solar power. They have solar panels that transform sunlight into electricity and store this in batteries for home use. Most other people who use solar power also use power from fossil fuels. They have solar panels but are also connected to the electricity grid, so they also use mainsteam electricity, which is mostly generated by burning fossil fuel.
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.
It's alot but it's true 200,00
Yes they can. Lots of people use solar power in their homes for all sorts of things, like heating their homes for example.
66,987,417,86 people use solar energy
At night you don't have power for anything
Solar energy is used by many to power appliances and machines in homes and businesses. It is also used for heating and cooling purposes.
