What is the lifetime of a photovoltaic installation?
The lifetime of a photovoltaic installation is at least 25-30 years in Poland. It depends mainly on the prevailing weather conditions, the location of the PV Installation and the quality of the components used. High-quality mounting structures, photovoltaic modules and inverters extend the life of photovoltaics. The most important thing to consider when selecting photovoltaic panels is their parameters, especially those related to the efficiency of the solar panels. The parameter that largely determines the lifetime of a photovoltaic system is the Linear Efficiency Guarantee. This parameter can be found on the technical data sheet of photovoltaic panels and indicates the rate of annual degradation of modules in a perspective of 25 or 30 years most often.
How long does it take to install photovoltaics?
Photovoltaic installation usually takes 1-2 days. The time from start to completion depends on the efficiency and experience of the installation team. A large impact on extending the installation time is often also due to unfavorable weather conditions. Larger photovoltaic installations are governed by slightly different laws. Photovoltaics are installed in several design stages, and very often there are additional requirements related to obtaining building permits or environmental approvals. The installation of large PV projects can take from several to even more than a dozen months.
Is a photovoltaic installation safe?
Yes, a photovoltaic installation designed and made by an installation company with many years of experience and using panels, inverters and high-quality solar electrical equipment and cables is a very safe electrical equipment. The danger of electrocution or the risk of fire occurs most often as a result of mistakes in the design or errors of the installation team. Fire safety regulations. regarding photovoltaics, amended on August 19, 2020, have increased restrictions, so that the risk of faulty installation is now lower. According to the new regulations, any installation with a power of more than 6.5 kWp requires that the project be agreed with a fire safety expert and the authorities of the State Fire Service be notified.
