SCHOTT SOLAR PV RUNNING COSTS

In general, PV solar power installations need no - or very little - servicing since they contain no rotating parts, bearings or other high-maintenance components.

The solar modules are installed on the roof in such a way that as much energy as possible can be generated. Most slanted roofs which point south are suitable for the installation of solar systems. A roof inclination of between 15° and 50° is optimal. Structures on the roof such as chimneys and skylights must in all cases be considered during the planning of the system.

If the angle of inclination of solar power installations is more than 20° to the horizontal, the modules are automatically cleaned by the rain. In other words, the modules are self-cleaning. However, if there are a lot of trees nearby and leaves accumulate on the modules, these need to be removed as quickly as possible. Leaves shading individual cells can considerably reduce the yield of the whole installation.
