The numbers
Why retrofit
Buy cheap. Use at peak.
Peak shaving.
Cut your most expensive half-hours and reduce capacity and DUoS red-band charges.
Stop clipping losses.
Capture the generation your inverter currently throws away on bright days.
Load shifting.
Move self-generated or off-peak energy into your costly import periods.
Resilience for production.
Ride through short outages and voltage events without dropping a line.
Export where it pays.
Where tariffs reward it, discharge to the grid at peak value as grid services.
Up to 100% year-one tax relief.
Qualifying plant typically attracts up to 100% first-year relief through capital allowances — your accountant confirms the treatment; our proposals itemise the equipment.

The approach
Retrofit to the solar you already have.
- AC-coupling adds storage alongside your existing panels and inverters — no need to replace working equipment.
- Half-hourly, data-led battery sizing for the fastest return, modelled on your real consumption and generation.
- Nova AI energy management for automated peak shaving and tariff optimisation.
- MCS-accredited installation by our own team, with NAPIT and RECC registration.
- A Quick Quote within 24 hours and a full technical proposal within 5 days of survey.
Nova AI
Your battery is only as good as the intelligence running it.
Nova AI is our energy-management platform. Every 30 minutes it makes the call for your battery — buy energy while it’s cheap, use it, store it, or sell it against live tariffs and grid signals — so the system earns its keep every day without anyone touching it.
- Energy arbitrage — buy low, store, and use or sell when prices peak.
- Automated peak shaving and load shifting against your live tariff.
- Virtual power plant ready — access grid services revenue.
Proof
Delivered for UK manufacturers and distributors.
Novalux completed a 1.25MWp system for Twinings (ABF Group) and a 208.8kWp solar array with 258kWh of battery storage for LWC Drinks in Liverpool — the kind of projects where storage and smart control decide the numbers.
Questions
The questions asked before every retrofit.
Can I add a battery without replacing my solar panels or inverter?
Yes. AC-coupled systems add a battery to almost any existing installation without replacing your panels or inverter. We size storage to your generation profile and how your site actually uses power.
What size battery do I need?
It depends on your half-hourly consumption, your generation profile and your tariff. We model all three and quote the battery size with the fastest payback — typically alongside 25-year cashflow, NPV and annual savings for each option.
What is the payback period?
Commercial solar-plus-battery systems typically pay back in 2–5 years, after which the electricity the system shifts and sells is essentially free money. Your Quick Quote includes the payback figures for your site.
How long does installation take?
A typical commercial retrofit installs in around 2 weeks, with G98/G99 notifications, protection relay requirements and DNO interaction handled by us.
What does a commercial battery retrofit cost?
It depends on the power and capacity your site needs, which come out of your half-hourly data rather than your roof size. The cost calculator gives a budget range in seconds, and a Quick Quote with the real figures for your site follows within 24 hours.
Is there tax relief on commercial battery storage?
Qualifying plant typically attracts up to 100% year-one relief through the £1m Annual Investment Allowance, and the equipment is exempt from business rates until 2035. There is no live UK-wide grant for commercial battery storage — your accountant confirms the treatment, and our proposals itemise the equipment so they can.
Can I add a battery with no upfront cost?
Yes. Power Purchase Agreements, rental and hire purchase up to 10 years all run with £0 upfront. Under a PPA the provider owns, maintains and insures the system and you buy the power at an agreed rate.
Do you handle the DNO application?
Yes. G98, G99 and G100 notifications, export limitation and protection relay requirements are all handled by our team as part of the project — you do not deal with the network operator.
