Is the purchase of an electricity storage unit for a photovoltaic system worthwhile? - Calculate Now

The conservative cost of electricity continues to rise inexorably and many photovoltaic system owners would like to have a reliable and affordable electricity storage system to achieve stable consumption costs in the long term and reduce electricity costs.
Unfortunately, the offers on the market are still too opaque or simply too expensive for consumers due to the complexity, the lack of experience and the almost abolished feed-in tariff.
Lithium-ion storage batteries cost at least 8,000 EUR to purchase. The cheaper alternative is to use lead-acid batteries. Their costs are at least 3,000 EUR for small PV systems (3 kWp).
What is needed, therefore, are clear, transparent solutions for calculating the share of self-consumption or calculating the costs in kilowatt hours per cent with electricity storage compared to electricity costs without storage. The goal is to achieve the highest possible self-consumption share for the photovoltaic system, only then can the system be profitable.
The electricity storage calculator gives you the chance to assess whether the purchase of an electricity storage system can be interesting and profitable for you. You can compare the calculated value directly with the extrapolated electricity costs of 30 cents per kWh plus the price increase rate - e.g. in the next 20 years.
As a rule, the photovoltaic system with electricity storageperforms significantly better. A falling price trend for electricity storage systems can be expected in the next few years. The retrofitting of an electricity storage system in an existing photovoltaic system is also interesting.
