An inverter converts the direct current (DC) generated by the solar panels into alternating current (AC) that can be used in the household or the power grid. Without an inverter, most electrical appliances could not be operated as they rely on alternating current.

A PV system consists of solar modules that convert sunlight into electrical energy. This energy is generated as direct current and converted into alternating current by an inverter, which can be used in the household or in the power grid.

Solar systems reduce electricity costs, increase energy independence and contribute to environmental protection by using renewable energy sources. They can also increase the value of a property and receive state subsidies in some regions.

Solar modules generally have a service life of 25 to 30 years and require minimal maintenance. However, regular cleaning and inspections by specialists can improve the efficiency and longevity of the modules.

Yes, it is possible to fully power a home with solar energy, depending on the size of the solar system and the household’s energy consumption. In some cases, it may make sense to install an energy storage system to store surplus energy and use it when needed.

Surplus energy can be stored in a battery storage system or fed into the electricity grid. Many countries offer feed-in tariffs where homeowners are paid for the electricity fed into the grid.

There are three main types of inverters: string inverters, micro inverters and hybrid inverters. String inverters are the most commonly used and the most cost-effective. Micro-inverters are more suitable for complex roof structures and partial shading. Hybrid inverters can be combined with battery storage systems. The choice of the right inverter depends on the specific installation and requirements.

The performance of a PV system can be affected by weather conditions such as cloud cover, rain and snow. Although solar systems are most efficient in direct sunlight, they can also generate energy in diffuse light. Extreme weather conditions such as hail can damage the modules, but high-quality solar modules are often resistant to such conditions.

Yes, solar systems can be customized for apartment buildings and commercial buildings. The scalability of the systems makes it possible to use larger roof areas and higher energy requirements efficiently.
