In a typical household, the demand for electricity reaches its peak both in the morning and then again (for a longer period) in the evening. Unfortunately, maximum generation from solar PV occurs during the middle of the day. So, unless you are in the house all day, you are unlikely to use all the power your system produces. It therefore makes sense to store that energy for later use.
According to the Microgeneration Certification Scheme (MCS), the body responsible for certifying low-carbon energy technologies and contractors, the number of annual solar electric panel installations in the UK more than doubled in 2022 to over 130,000. No doubt the homeowners specifying this renewable technology are hoping to make a sizable dent in their future energy bills – but the question is, will they be successful?
