A solar panel storage, also known as a solar battery storage, is a technology developed to store excess solar energy generated by photovoltaic solar systems. These storage systems allow storing the generated electricity during times when the sun is not shining or when the electricity demand is lower, in order to use it later when energy demand is higher.
The functioning of a solar panel storage is relatively straightforward: while the sun is shining, the solar panels produce direct current (DC), which is converted into usable alternating current (AC) by an inverter. Part of this electricity is immediately consumed in the household, while the surplus electricity is directed into the battery of the storage system. This battery stores the energy so that it can be used later.
A significant advantage of solar panel storage is that it can enhance self-sufficiency with solar energy. Households can store surplus electricity generated during sunny periods and retrieve it when the sun isn't shining or during times of higher electricity demand. This can help reduce the reliance on electricity from the public grid and lower energy costs.
Solar panel storage can also be beneficial during power outages, as they are capable of maintaining a limited power supply in emergencies. Therefore, they offer a degree of independence from the public power supply.
The technology of solar panel storage has improved in recent years, and there are various types of batteries that can be used, such as lithium-ion batteries, lead-acid batteries, and more. The choice of battery depends on individual needs, budget, and performance requirements.
In summary, a solar panel storage allows for the efficient utilization of generated solar energy by storing excess electricity and using it during times of lower energy generation or higher demand. This contributes to maximizing energy self-sufficiency and can offer both financial and environmental benefits.
