If electricity isn’t stored, it has to be used at the moment it’s generated. In private households, the main energy consumption usually takes place in the evening, when the sun is already setting. Surplus energy produced during the day is normally sold back to the grid. But there is another option – storing solar energy in batteries. By adding a battery to the system, you can use solar energy in the evenings. The more of your PV plant produced energy you self-consume, the more profitable is your solar park and thus, the shorter is the payback period. The most affordable electricity is the production of your own PV plant. By producing solar electricity and maximising self-consumption, you will protect yourself from possible major fluctuations in electricity prices for decades.
During the winter, when solar irradiance is low and the productivity of the panels is modest, the batteries have an additional function. During the evening and night you can recharge batteries with cheaper energy, and during the day, when the electricity price is expensive, you can self-consume or sell the stored energy back to the grid.
You can add battery packs to your solar panels later, after the PV system in operational. Please mention your interest in (future) energy storage to the sales representative early on.
Solarstone PV systems can be successfully implemented both on-grid and off-grid. In the case of off-grid solutions, the system can also be combined with a generator, which ensures almost complete autonomy and ensures an independent local grid.
