Solar Battery Storage
It wasn't long ago that households and businesses that had installed solar PV to roofs were only able to use the energy generated on a 'use it or lose' it basis. If the power was not consumed, excess energy generated would automatically be transferred to the National Grid. During the longer daylight hours of British summertime, this is a regular occurrence. However, an alternative to this is solar battery storage.
In the past, batteries were considered an expensive option to offset the loss of energy to the grid. However, there have been significant developments in battery technology in recent years. This has resulted in solar batteries becoming a more viable and cost-effective solution to energy storage.
The basic concept of solar battery storage is that the battery is charged using excess solar energy during the day. Then during the evening you can use power provided by the energy stored in the battery. Systems can be sized which allows properties to be self-sufficient for the majority of the summer months. Helping you towards going completely off-grid!
Certain systems can provide a further add-on benefit that the battery provides an automatic back up facility. This means that certain circuits (such as downstairs sockets) can be protected against any mains grid outages. So if there is a black out, you don't need to worry!
