Across the UK and Europe, the commercial solar market has matured rapidly over the past decade. Thousands of businesses have already invested in rooftop solar PV, often achieving strong returns through reduced grid dependency and energy cost savings.
As energy markets evolve, geopolitical influences become more frequent and grid pressures intensify, an increasing number of systems are no longer operating at their full economic or technical potential.
The cause can be summed up simply: generation without control.
Battery energy storage systems (BESS) are now emerging as a viable, and, some might argue, critical, next step, transforming solar assets from passive generators into actively managed energy systems.
Exploring the value gap in existing commercial PV systems
Many commercial installations were designed around a straightforward principle: generate as much solar energy as possible
and offset onsite demand. This, in itself, in many areas of the UK especially, is already becoming a challenge and few systems are installed without some sort of export power limitations.
In practice, this has led to structural inefficiencies, including excess midday generation being exported at low value, energy being re-imported during peak tariff periods and short-duration demand spikes continuing to drive high capacity charges.
In an energy market characterised by volatile pricing, half-hourly pricing and increasing network constraints, this model leaves significant value on the table, largely untapped. Battery storage directly addresses this gap.
