There are several factors to consider when installing a solar system. One of the most important considerations is the orientation of the solar panels. In order to maximize energy production, solar panels should be installed facing south in the Northern Hemisphere and facing north in the Southern Hemisphere. Additionally, shading should be avoided as much as possible, as even a small amount of shading can significantly reduce the efficiency of a solar system.

Another consideration when installing a solar system is the size of the system. The size of the solar system will depend on several factors, including the amount of electricity that is needed, the orientation and location of the solar panels, and the amount of available sunlight. Finally, it is important to work with a qualified and experienced installer who can help to ensure that the solar system is installed correctly and meets all local and national regulations.
