Solar System Expansion - Is it possible?

The article is about how to expand solar systems, with a focus on inverters, solar panels and optimisers. Solar systems ideally cover average consumption, but consumption may increase after the system has been installed, for example due to the use of air conditioning or an electric car.

If such changes are anticipated when designing the system, it may be worth installing a larger inverter to allow for easy expansion later, or even installing a larger system from the outset. However, it is important to note that it is not worth installing too large a system, as the electricity supplier will buy the electricity they buy at a low price.

The article stresses that when expanding a solar PV system, a number of technical aspects need to be taken into account to ensure that the system works properly. The advice of experts is recommended for the expansion.

It highlights three main aspects of expansion: the inverter, the free roof space and the type of solar panels.

The inverter plays an important role in the expansion and to ensure that the inverter can handle the added power. Inverters are usually oversized, but the phase number of the inverter must also be taken into account.

Optimisers are also important, as they help to ensure that the performance of solar panels is not reduced if one of them is exposed to shading or dirt.

The compatibility of solar panels is also highlighted and it is recommended that the technical characteristics are similar, even if different brands of solar panels are used for the expansion. For old systems, it is important to involve optimisers and specialists in the design of the expansion.

Finally, the article mentions the development of solar cells, in particular the renaissance of monocrystalline solar cells, which are more efficient and cheaper to produce than earlier types. However, there are some technical difficulties in combining different types of solar cells.

The article encourages readers to contact experts if they want to upgrade their solar system to make the best decision for the efficiency and yield of their system.
