About MCS

MCS is a mark of quality and demonstrates
compliance to industry standards that companies
strive to meet. It highlights to consumers that
companies are able to consistently install or
manufacture to the highest quality every time.

As interest grows in the role that battery storage can play in improving the performance of solar PV systems by capturing any surplus electricity generated (allowing consumers to store solar electricity for use later in the day), the Renewable Energy Consumer Code (RECC) along with BRE’s National Solar Centre (NSC) have drawn up some guidance for installers and consumers.

In the absence of formal standards, you are able to find some useful information below about how battery storage can work alongside a solar PV system, whether retro-fitted to an existing installation or fitted as part of a new installation, along with RECC and NSC consumer guidance.
