How can people get solar energy?
Yahhh, people can get solar energy by solar panels. But the fee of solar panels is very expensive. They are from $12,141 to $45,296 depend on : system size, average cost per watt and roof space required. Photovoltaic modules use light energy (photons) from the Sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most modules are rigid, but semi-flexible ones based on thin-film cells are also available. The cells must be connected electrically in series, one to another.
A PV junction box is attached to the back of the solar panel and it is its output interface.Externally, most of photovoltaic modules use MC4 connectors type to facilitate easy weatherproof connections to the rest of the system. Also, USB power interface can be used.
