Solar modules for the balcony at home

So far, the construction of solar systems has been accompanied by a certain social imbalance. Because these could only be installed if there was enough space available. Landowners and homeowners in particular benefited from this. Tenants, on the other hand, had to pay the EEG surcharge, but could not generate solar power themselves. At least the latter has changed in the meantime. Because numerous companies have developed small solar modules for their own four walls. An example of this is the Leipzig company Priwatt. This sells modules with a size of 1.70 meters and a width of one meter. They are also so light that they can easily be attached to balcony grilles. Then the system only needs to be connected to the socket via an inverter. The solar power is then used initially in one’s own apartment. It is only fed into the public grid when there is no longer any need there.

The installation pays for itself after a few years

Above all, personal use is financially lucrative. Because in this way the annual electricity bill can be reduced significantly. A module with an output of 600 watts costs 850 euros to purchase. As a rule, ten to fifteen percent of your own consumption can then be covered by this. This corresponds roughly to an annual saving of 175 euros. In purely mathematical terms, the installation was worth it after just four and a half years. Electricity prices have also risen sharply in recent years. If this trend continues, the balance for the solar system on your own balcony would be even better. Especially since the modules were designed for a period of 25 years. Priwatt also advertises that it will take over the bureaucracy that arises. On request, the company can register the new system with the local energy supplier and the Federal Network Agency. The customer doesn’t have to do much more than hope for regular sunshine.

In theory, millions of additional modules could be installed

However, the Leipzig company is only one supplier among many on the market. In addition to the traditional energy providers, numerous startups are also entering the market. So far, however, the number of systems actually installed is still comparatively small. This could change in the future. The consumer advice center estimates that theoretically around one million solar systems could be installed in rental apartments in North Rhine-Westphalia alone. In some cases, the public sector supports the acquisition with three-digit amounts. The funding usually goes hand in hand with additional paperwork. Should tenants actually decide to install a solar system in the future, this should massively increase the number of modules installed in Germany. There are currently more than two million systems in this country that cover around ten percent of electricity consumption. Obviously, the potential has not yet been exhausted.
