FARM BATTERY RETROFIT
Stop exporting electricity, use more and cut costs with BESS
Keep the daytime generation you currently export for pennies and use it when you need it — overnight in the sheds, during milking, grain drying and refrigeration. Novalux retrofits AC and DC-coupled storage to any existing farm solar system.
Commercial battery systems typically qualify for 100% capital allowances — a year-one tax deduction. Ask us for the figures for your business.

WHY RETROFIT
Why farms are adding storage now
Solar only pays while the sun is up. A battery lets your farm use its own energy around the clock, cut expensive grid import and stay running when the network drops.
- Stop exporting cheaply — store surplus generation instead of selling it back at a fraction of what you pay to import.
- Power your operation overnight — sheds, cold stores, milking parlours and pumps run on stored energy, not peak-rate grid.
- Backup when the grid drops — keep ventilation, refrigeration and biosecurity running through outages.
- Beat rising standing and red-band charges by shifting import away from the most expensive periods.
- Get more from your existing G99 grid connection without waiting on a DNO upgrade.
- Don't underutilise your battery - leverage our Nova AI Energy Management System (EMS) to turn your battery into a trading asset. Buy energy in low cost periods, store and sell back, when grid prices are highest.
THE APPROACH
Retrofit to the solar you already have
Our AC and DC-coupled systems add a battery to almost any existing installation without replacing your panels. We size storage to your generation profile and how the farm actually uses power across the day and seasons. Where the grid is limited or absent, we design off-grid and hybrid systems with generator backup.
- A battery sized to your farm’s real load profile, not a generic figure.
- Nova AI energy management to optimise charge, discharge and tariff use automatically.
- Full support with your G99 / DNO paperwork.
- Our DC coupled systems remove the need for more grid connection capacity.
- MCS-accredited installation by our own team.
- A Quick Quote within 24 hours and a full technical proposal within 5 days of survey.
PROVEN ON FARMS
Delivered across working UK farms
Novalux delivered over 1MW of solar and 200kWh of battery storage across the R.S. Cockerill three-farm programme in Yorkshire, and an 81.27 kWp off-grid solar, battery and backup-generator system at Link Hall potato farm.
Novalux were always very transparent about how they were putting together proposal costings around our requirements. They were absolutely safe, and they didn’t disrupt our operations.

OFF-GRID & REMOTE SITES
Off-grid storage where the grid can’t reach
Not every site has the grid connection its operations need — and an upgrade can cost more than the system itself. At Whitebarn Mill in Worcester we replaced an oversized diesel generator with an off-grid micro-grid: 400kWp of solar orchestrated with a 600kWh battery, switching automatically between solar, battery and generator. The mill now runs largely on its own generation, with no costly grid upgrade. If your farm is grid-constrained, ask us about off-grid and hybrid designs in your quote.
- 13.3% return on investment — before counting the avoided grid-connection costs.
- 7.5-year system payback on delivered figures.
- 42,858kg of CO2 avoided every year.
SMART ENERGY MANAGEMENT
Powered by Nova AI
Your battery is only as good as the intelligence running it. Nova AI is our energy management platform that turns your solar and storage into a self-optimising asset — automatically buying, storing and discharging energy against live tariffs and grid signals to earn its keep every day.
- 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 and VPP trading revenue.
QUESTIONS
Farm battery retrofit FAQs
Yes. Our AC-coupled retrofit works alongside your existing panels and inverter, whatever the brand and our DC coupled systems require a simple and inexpensive swap to our hybrid inverters.
Battery systems typically qualify as plant and machinery for capital allowances — often a 100% deduction in year one via the Annual Investment Allowance. We set out the exact position for your site in your proposal.
It depends on your generation and overnight use. We size every system individually after reviewing your consumption during the free survey.
Most commercial battery retrofits pay back in around 2 to 4 years, depending on tariff and usage. Your proposal shows the figures for your site.
