One of the largest single-site commercial solar installations delivered by Sol4r Energy — a landmark project powering an entire resort from its own roof.
Laceby Manor Resort is a premier hospitality and leisure destination in Laceby, near Grimsby, Lincolnshire — a large-scale commercial operation with substantial year-round electricity consumption of over 920,000 kWh per year. With energy costs representing one of the resort's largest operating expenses, the business case for solar was overwhelming.
When Laceby Manor Resort approached Sol4r Energy about a commercial solar installation, the ambition was clear from the outset: go big. Not a partial offset — a full megawatt-scale system capable of generating more electricity than the entire resort consumes. The result is one of the largest single-site solar panel installations Sol4r Energy has delivered — a 1MW (1,000 kWp) system comprising 1,600 solar panels with 229 kWh of Sungrow battery storage, designed to transform the resort's energy economics for decades to come.
This is not a small rooftop installation. This is industrial-scale clean energy generation — the equivalent of powering approximately 300 average UK homes — deployed at a single commercial site in Lincolnshire.
A premier hospitality and leisure resort in Laceby, Lincolnshire — currently having one of the UK's largest single-site commercial solar installations fitted. When complete, the resort will generate more electricity than it consumes. 1,600 panels. 1 megawatt. Zero compromise.
Laceby Manor Resort now has a megawatt-scale solar and battery system designed to generate clean electricity, reduce operating costs and protect the business from rising energy prices.
At this scale, the numbers are extraordinary. Every single month of the year the resort saves tens of thousands of pounds — and exports surplus electricity back to the grid on top:

This system generates nearly one million kilowatt-hours per year — more electricity than the entire resort consumes annually. That's the equivalent of powering approximately 300 average UK homes from a single commercial site. With the 229 kWh Sungrow battery bank, self-consumption is maximised and surplus generation is exported at 15p/kWh via the Smart Export Guarantee. If your hotel, resort, leisure centre, or commercial business in Lincolnshire, Grimsby, Cleethorpes, Scunthorpe, Hull, Lincoln or anywhere across the UK is considering large-scale commercial solar, this project demonstrates what's achievable with the right partner.
At megawatt scale, the battery isn't a luxury — it's essential infrastructure. The Sungrow ST225kWh system transforms how Laceby Manor manages energy across every hour of every day.
Without batteries, only 37.3% of solar generation would be self-consumed. The 229 kWh Sungrow battery lifts this to 43.3%, with 150,453 kWh discharged annually — keeping the resort powered when solar dips.
Surplus generation earns 15p/kWh through the Smart Export Guarantee. With nearly 50,000 kWh exported annually, that's significant additional income on top of the bill savings.
Octopus Intelligent charges 7p overnight (11pm–5am) and 31p during the day. The battery charges at the cheap rate and discharges during peak hours — compounding savings daily.
Hotels and resorts cannot afford power disruptions. The 110 kW discharge rate ensures the resort can draw heavily from stored energy during peak guest activity without touching the grid.
The battery bridges the gap when solar generation drops — powering kitchens, bars, accommodation, and event spaces from stored energy rather than expensive grid electricity.
With energy costs rising 7% annually, the resort's savings compound relentlessly. By 2038, annual savings exceed £1 million. By 2050, cumulative savings reach £26.5 million — from a single investment.
At 246 tonnes of CO₂ saved annually, this single installation has a greater environmental impact than most solar farms. Over its lifetime, the system is equivalent to planting 47,206 trees or taking thousands of cars off the road permanently. For a hospitality business where guests increasingly expect environmental responsibility, this installation is a powerful statement — not just a cost-saving measure. Sol4r Energy installs large-scale commercial solar systems for hotels, resorts, leisure centres, and businesses across Lincolnshire, Grimsby, Cleethorpes, Scunthorpe, Lincoln, Hull and nationwide.
All certifications issued on completion. Sol4r Energy is HIES-registered, NAPIT-approved, TrustMark-endorsed, and ISO 9001:2015 certified — the highest level of consumer protection for solar installations in the UK.
