Say NO to oversizing PV systems due to winter production declines

In winter, a photovoltaic power plant produces only about 20-25% of the electricity it produces in summer. However, oversizing photovoltaic systems just because of winter is definitely not optimal. You will not increase your winter production by that much, but in summer you will have to deal with huge surpluses. A large power plant will also be significantly more expensive due to the higher number of panels and the need for a more powerful inverter.

Shading of photovoltaic panels reduces the performance of photovoltaics. What can be done about it?

A chimney, a neighbor's tree, or even a building across the street. Shading of a single photovoltaic panel is enough to significantly reduce the performance of the entire system. Long-term shading of panels not only affects performance but can also cause panel degradation. The installation company should take this into account when designing a photovoltaic system. If shading cannot be avoided, there are solutions in the form of bypass diodes or power optimizers that help mitigate the effects.

Hybrid photovoltaic power plants

An important part of the answer to the challenge of integration will be to combine generation and storage on the same site. In the near future, the combination of freestanding solar installations and storage systems will be the new norm - a trend we are already seeing in the German residential storage market.

Five reasons to say NO to DIY photovoltaics

You can find dozens of DIY photovoltaic guides on the internet. How to buy panels, attach them to the roof, connect the inverter, and get the system up and running without the help of a professional company. At first glance, it looks tempting and simple. But on closer inspection, you will find that it is not a good idea at all.
