Generate it. Store it. Use it when it counts most.
Solar and battery work together as a coherent energy ecosystem. Solar cuts what you pay during the day. Battery storage captures what you don’t use and deploys it when grid prices are at their highest.
Four site conditions that determine Solar + BESS suitability
When you pay most
Peak grid rates hit hardest in winter evenings. If your site runs then, a battery discharging at that point cuts your most expensive consumption.
Cheap overnight charging
Off-peak overnight grid rates are often less than half the daytime rate. A battery charged at night and discharged during peak hours turns that price gap into a direct saving.
How much solar you use
Surplus solar exported at low rates is value lost. A battery stores that surplus and releases it when grid power would otherwise cost 3–4× more.
Shape of your demand
Short demand spikes drive up your capacity charges even if average load is modest. Peak shaving those spikes directly reduces fixed charges on your bill.

Where Solar + BESS is most suitable
- Half-hourly settled tariff with time-of-use pricing
- Evening or multi-shift operations
- Solar export ratio above 30%
- Peak demand well above base load
- Annual electricity spend above £150k
- Own site or remaining lease of 7+ years
Typical Industries
- Food and beverage
- Cold storage and distribution centres
- Leisure centres
- Hotels and hospitality
- Businesses with EV charging demand

Two numbers. One decision.
Battery systems are defined by power rating and energy capacity. Getting the balance right between the two is what drives payback.
kW
POWER RATING
How fast the battery charges and discharges. Critical for sites with short, high demand spikes – machinery start-ups, shift changeovers.
kWh
ENERGY CAPACITY
The total energy stored per cycle. Critical for sites needing sustained discharge across several hours of evening operation.
UrbanVolt will assess 12 months of your half-hourly data to tailor your system size.
Two ways to add BESS to your Solar. No compromise on what's included.
Both options include full installation, a manufacturer’s warranty, and a preventative maintenance package. The difference is how you pay for it.
Operating Lease
Fixed monthly payments with no upfront capital required. UrbanVolt installs, monitors, and maintains the system throughout the agreement term.
CapEx Purchase
Own the system outright from day one. Includes the same warranty and preventative maintenance package - your asset, fully supported.
