Self-sufficiency through solar power storage

With a solar power storage unit, you achieve greater self-sufficiency. You can cover more of your electricity requirements yourself and also protect yourself against grid failures. Becoming more independent of energy providers pays off financially. Learn here how you can boost your degree of self-sufficiency.


What does self-sufficiency with solar power stand for?

If you use the electricity that you generate yourself, it is referred to as self-consumption. Self-sufficiency is the share of self-consumed solar power in your total electricity demand. For ideal self-sufficiency of 100 per cent, you would cover your electricity requirements exclusively by your photovoltaic system (including solar power storage). A high degree of self-sufficiency is difficult to achieve, especially in the winter months. Realistic values are 60 to 80 per cent.


Boost your degree of self-sufficiency
- become more independent of the electricity provider.

The sale of PV systems is booming. However, many system owners feed a large share of their self-generated electricity into the public grid and do not use it for themselves. The main reason is how electricity is consumed in a household. Photovoltaic systems generate the majority of their electricity output during the midday hours. System owners, though, usually need the electricity in the morning and the evening hours when they are at home. Here is where a power storage system can help. It temporarily stores the generated solar power for use at a later time.  Every kilowatt-hour of electricity self-consumption will boost your self-sufficiency and your independence.


Benefits of electricity self-sufficiency

  • Use of renewable energies
  • More independence of rising electricity prices
  • In combination with solar power storage and backup power function: protection against power failure



This is how you boost the degree of self-sufficiency!

Solar modules: There is a simple calculation. The more electricity you generate on your roof, the greater your degree of self-sufficiency can be. You need about 5 square metres of the roof surface to install 1 kWp (= kilowatt peak) of photovoltaic power. Depending on the location and orientation, a PV system with 1 kWp output generates about 1000 kWh of electricity per year.

Solar power storage: You can raise your self-consumption rate easily and effectively with a small PV system and a power storage unit. The storage battery stores the generated energy during the day. You can then consume the energy in the evening, at night and the next morning. The discharged storage unit can then be recharged the whole day by the PV system. Solar energy storage systems make you practically independent of weather conditions and time. In short, you will almost always have self-generated electricity available.

Energy savings: Self-sufficiency is the share of self-consumed solar power in your total electricity demand. Using energy-efficient washing machines, refrigerators and other appliances will reduce your initial electricity demand. If you combine this with continued self-consumption of self-generated solar power, you will also boost the degree of self-sufficiency.


Become more self-sufficient

A generously sized PV system with a matching power storage unit is a safe and convenient method to become more self-sufficient and independent of the public grid. You will also be well covered for the acquisition of an electric vehicle or a heat pump. RCT Power solar power storage units are very efficient storage solutions for photovoltaic systems. Due to their modular design, they are suitable both for new installations and for retrofitting existing PV systems. With our storage systems, you will take a big step forward towards electricity self-sufficiency. We are happy to accompany you on this journey.
