Electricity storage in your own home: Is the investment really worth it?

Electricity storage in your own home: Is the investment really worth it?

In recent years, the demand for photovoltaic systems and electricity storage in private households has increased significantly. This development is due to rising electricity prices and a growing awareness of environmental protection. How oekonews.at reports, the use of a battery storage system makes enormous sense even without a photovoltaic system: households can thus obtain cheap energy from energy communities or the spot market. At a price of 250 euros per kWh of storage capacity and a service life of at least 5,000 cycles, the storage of 1 kWh can be realized for around 5 cents, while the savings through these measures are over 10 cents per kWh. This results in an economic advantage if you carry out a charging cycle every day.

The integration of electricity storage has proven to be crucial for the efficiency of photovoltaic systems solarwissen.selfmade-energy.com explained. These battery storage systems act as accumulators, storing the solar power generated during the day for use in the evening when demand is highest. Although the feed-in tariff for solar power has fallen continuously in recent years, the storage systems make it possible to maximize self-consumption and thus significantly reduce electricity costs. In an example with a PV system and electricity storage, the payback period is estimated to be around 12.6 years, although decreasing costs for storage capacity could shorten this time even further.

Economic efficiency and service life of electricity storage systems

The economic viability of an electricity storage system depends on several factors, including the acquisition costs and the lifespan of the system. High-quality lithium-ion batteries are considered the most economical solution for private households and offer a service life that has a positive impact on profitability. Sharply increased self-consumption rates, which can range from 70 to 90 percent, also contribute to the attractiveness of this technology, as the costs of purchasing grid electricity continue to rise. The combination of these factors suggests that investing in electricity storage not only makes sense, but is also worthwhile given the patented supply and price structures.
