Frequently Asked Questions
Answers to popular questions about photovoltaics
How long does it take to install a photovoltaic system?
The installation of a typical photovoltaic system for a single-family house usually takes 1-2 days. The entire process from signing the contract to commissioning the system can take from 2 to 8 weeks, depending on the waiting time for grid connection by the energy supplier.
Does a photovoltaic installation require maintenance?
Photovoltaic installations are practically maintenance-free. However, it is recommended to clean the panels periodically (1-2 times a year) and check the system's performance. Most manufacturers offer online monitoring, which allows you to track the installation's efficiency in real time.
What is the lifespan of photovoltaic panels?
High-quality photovoltaic panels have a lifespan of 25-30 years. Manufacturers usually guarantee that after 25 years, the panels will still achieve at least 80% of their initial efficiency. Inverters have a shorter lifespan, about 10-15 years.
