Solar energy is the energy produced by the sun's rays. Solar panels convert sunlight into electricity through a process called the photovoltaic effect. When photons from the sun's rays hit the solar panel, they knock electrons in the panel's silicon atoms loose, which creates an electrical current that can be harnessed and used as electricity.

The amount of area required for solar panels depends on several factors, including the size of the solar panel system, the type of solar panels, and the efficiency of the panels.
On average, a residential solar panel system that generates 5 kilowatts of power would require about 300 to 400 square feet of space, but this can vary depending on the specific circumstances of each installation.
It's important to note that the amount of energy you want to generate and your energy usage will also play a role in determining the size of your solar panel system, which will in turn affect the amount of space required for installation.

A. Net metering is a billing system that credits solar panel owners for the excess electricity they generate and send back to the grid. If your solar panel system produces more electricity than you use, the excess energy is sent back to the grid, and you receive a credit on your electricity bill for the excess energy.

Eirsun’s Solar panels generally have product warranty of 10years and power warrant of 25years subject to proper maintenance and care.
For specific model warranty please refer to its datasheet.
