Storage systems are now increasingly establishing as an important technical solution to match to photovoltaic systems to improve their performances and use of energy.
The need of using the solar energy even when the sun is not present entailed the technological research as well as technical solutions that allowed to guarantee energy autonomy even in isolated situations, especially in off-grid plants.
Today there are a new market and new conditions thanks to the definition of clear rules and well-established technologies, given also by the introduction of lithium batteries, which guarantee high performances and high energy availability.
VP Solar: your specialized distributor of storage systems
When talking about storage, we are not only dealing with storage batteries, but it is always more important to talk about an overall system which allows to get the maximum from the energy produced and the right and highest efficiency in the management of the energy flow from and towards the building through an efficient and punctual management.
The electricity grid is fundamental in a storage system, not only to guarantee continuity if the battery or the PV plant cannot do it, but also because it is a big storage of energy able to collect it once the accumulation has been completely charged, especially during the summer.
Thanks to the connection to the grid that energy is not irretrievably lost, but it is valorized through the net energy metering.
