The ideal roof for solar electricity faces south with an angle of 30°. Thin-film modules, however, enable east/west-facing roofs or roofs with a slight angle to be used to achieve good yield. What is important is that the planner combines all available technology into an optimum overall solution. A prerequisite is a visit to the site. Phoenix Solar partners offer this service free of charge.
A solar electricity system can generally be mounted by an expert within a week. Minor electrical work has to be done in the house. In most cases, the existing cable channels can be used to lay the solar cable from the roof to the inverters and the house connection.
Your roof will be given a second skin. A few roof tiles will be lifted slightly only during assembly in order to screw the system onto the roof beams. Afterwards the tiles will again cover the area securely where the assembly was fixed. In future, your roof will be protected by the solar modules from the impact of the weather. It will heat up less in summer, and the tiles will have a longer life.
