Mini solar systems: saving electricity made easy
Large photovoltaic systems on the roof? That doesn't have to be the case! Mini solar systems offer a cost-effective and simple way to generate your own electricity. Simply plug it into the socket and the solar energy generated is fed directly into the household grid. This saves costs, protects the environment and pays for itself after just a few years.
Simple structure, great effect
In contrast to complex roof installations, mini solar systems can be used flexibly:
- Attachment to Balcony, façade or in the garden
- No complicated mains installation - simply connect via plug
- Easy to set up thanks to the supplied instructions
Important to know: Mini solar systems initially generate direct current. An integrated Inverter converts this into alternating current and adapts the voltage and frequency to your household grid. If you are unsure, you should have the installation checked by a specialist.
Cost-effective and quickly amortised
Investing in a mini solar system pays off: from as little as 400 Euro the compact panels are available. Experts estimate that the system can be installed in about five years amortised - at a constant electricity price. Under optimal conditions (south-facing and 70° inclination), the electricity can be generated for less than 10 cent per kilowatt hour generate.
A comparison is worthwhile:
- Current electricity costs: around 30 cent/kWh
- Savings: up to two thirds of electricity costs
Practical tips for use
The following points should be observed so that you can make optimum use of your mini solar system:
- Backstop: Check whether your electricity meter has a backflow preventer to avoid problems with excess electricity.
- Electricity storage: Battery packs make it possible to store surplus electricity - check whether this is worthwhile for you.
- Feed-in tariff: The sale of electricity is becoming less and less worthwhile due to falling tariffs.
The future of mini solar systems
Already 250,000 mini solar systems are in use in the European Union - primarily in Luxembourg and Austria. In Germany, the number is also rising steadily; there are currently around 40,000 systems. With rising electricity prices and growing environmental awareness, the trend will continue to increase.
