A solar energy system mainly produces electricity during midday and afternoon. An electricity or battery storage system stores solar electricity that you don’t use immediately to reuse it later. For example in the evening or in the morning when you and your family need more electricity.
Invest in the future
Unlike on grid solar system, electricity storage can be worthwhile and pay for itself if all the conditions are met. Above all, you save money if your energy supplier charges a lot for its electricity but pays little for your solar energy. This calculation may well pay off: Experts expect energy prices to rise in the next few years and feed-in tariffs to fall.

With such a scenario using more self-produced solar energy, i.e. increasing self-consumption is more than sensible. Then combine with a battery storage system.
Solar energy, ecological and economic benefits
Solar energy saves resources and the environment. A solar system on the roof generally pays for itself: you reduce your electricity costs by 30% in the long term, the increase in the price of electricity no longer has an impact, you increase the value of your house, secure state subsidies and optimize your tax burden.

With a high proportion of self-consumption, the investment generally pays off after 15 to 20 years with an average lifespan of 30 years.
Most households consume the most energy in the morning and evening. However, solar systems produce the most electricity at lunchtime, when only a few people are home. This is why many photovoltaic systems without storage only achieve a self-consumption of 30 to 35%. With a smart storage solution, you can optimize your consumption, store energy and use it when you need it: in the morning, in the evening or at night. You double the self-consumption share of more or less 70% and use the ecological electricity that you generate yourself 24 hours a day.
Role of Solar Batteries
The solar batteries store the energy produced by the photovoltaic panels in order to ensure the power supply in all circumstances.
A lithium battery used with solar panels or a wind turbine is a slow-discharge battery (also called a solar battery). These batteries are specifically designed for solar or wind applications. They do not have the same characteristics as a car battery for example, they discharge more gradually and better withstand frequent shallow discharges.
You can plug a solar battery directly into a solar panel, but you risk damaging the battery if its charge level exceeds 90%. This is why it is strongly recommended to install a solar inverter between the photovoltaic solar panel and the solar batteries.
The role of the regulator in a solar installation is very important because the charge level of the solar batteries must neither be too low (not below 40%) nor too high (not exceed 95%). Too low or too high unregulated loads deteriorate the batteries and limit their lifespan.
We recommend that you check that the cycle (number of complete cycles of charge – discharge of the battery) is clearly indicated by the manufacturer. The cycle indicates the lifetime of the solar battery. Quality solar batteries have a lifespan of more than 500 cycles, or 7 years up to 15 years.
