What our client Posterlounge says about us
In 2023, our landlord had the roof of his company building equipped with a PV system by MdE – Mitteldeutsche Energie KG. An e-charging station was also installed. This allows us to use solar power and we are thrilled with the electricity cost savings.

FAQ
The electricity production of a 10 kWp photovoltaic system per day depends on several factors, including location, season, weather conditions, and module orientation. In Germany, a 10 kWp system generates an average of 9,000 to 11,000 kWh per year, which corresponds to approximately 25 to 30 kWh per day on an annual average.
We are currently planning several open-field systems in Saxony-Anhalt with a total size of approx. 37 MW.
Yes, a photovoltaic system (PV system) is worthwhile in most cases – for both private individuals and businesses. The profitability depends on factors such as acquisition costs, subsidies, electricity price development, and self-consumption rate.
A photovoltaic system is not optimal for every company or investor, especially if self-consumption is low, roof conditions are poor, or the useful life is unclear.
However: In many cases, there are solutions such as leasing, tenancy, or alternative financing models that enable profitable implementation even under difficult conditions.
Basic rule: 1 kWp PV output generates approx. 3–5 kWh per day in Germany. For 10 kWh per day, approx. 2–3 kWp would therefore be necessary.
Recommended system output for a wallbox:
| Driving Performance | Required Solar Power (kWh/day) | PV Output (kWp) |
|---|---|---|
| 30 km/day | approx. 6 kWh | 2 kWp |
| 50 km/day | approx. 10 kWh | 3 kWp |
| 100 km/day | approx. 20 kWh | 5–6 kWp |
With a storage system, surplus solar power can be stored and charged at night. Without a storage system, charging during the day when the sun is shining is ideal.
The combination of photovoltaic system (PV) and battery storage can be economically viable for businesses – but not in every case. Decisive factors are electricity consumption, load profiles, electricity prices, and feed-in options.
Yes – renewable energies are currently one of the best investment opportunities. Due to rising electricity prices, climate targets, and political subsidies, they offer high return opportunities, long-term security, and sustainable benefits.
Yes, in many areas there are already legal requirements for renewable energies – and they are becoming increasingly strict. It is becoming increasingly difficult for companies and property owners to use fossil fuels. Medium-sized & large companies must regularly review and, if necessary, implement energy efficiency measures..
