Commercial Solar and Battery Storage at Kelgray House, Crawley
Commercial solar and battery storage for a growing Crawley business
Kelgray approached DW Energy during a period of business growth. As the company expanded and invested in additional printing machinery, rising electricity demand became an increasingly important commercial consideration.
DW Energy installed a 53.9 kW DC commercial solar PV system with 46.4 kWh of battery storage at Kelgray House in Crawley. The complete installation was delivered in just eight days, helping the business generate, store and use more of its own electricity on site.
Managing rising electricity demand from commercial printing equipment
Kelgray operates busy commercial premises containing energy-intensive printing equipment. As the business continued to grow, the team wanted to offset increasing electricity usage while maintaining normal day-to-day operations.
The system needed to be designed around Kelgray’s actual energy demand so that as much solar generation as possible could be used on site. Installation also needed to be completed quickly, safely and with minimal disruption to the business.
53.9 kW solar PV and 46.4 kWh commercial battery storage
DW Energy designed and installed an integrated commercial energy system comprising:
- 53.9 kW DC solar PV
- 46.4 kWh of commercial battery storage
- A projected annual solar generation of 56,600 kWh
- Monitoring to track generation, consumption and battery performance
- Full installation completed within eight days
The solar array generates electricity throughout the day. Battery storage allows Kelgray to retain more of that generation and use it outside peak sunlight hours, reducing the amount of electricity imported from the grid.
The installation was planned around the operation of the premises, allowing Kelgray to continue working while the system was completed.
Commercial energy savings recorded by May 2026
Since the system went live, Kelgray has recorded strong performance from its investment.
By May 2026, the system had delivered:
- Electricity savings of £21,405
- 71.35 tonnes of CO₂ savings
- Over 70% self-sufficiency reported by the business
Forecast payback in just over three years
The project financial model forecasts:
- A 769.7% return on investment
- A discounted payback period of 3.26 years
- Payback in approximately three years and three months
- A projected net present value of more than £600,000
Client testimonial
“As our business has grown and we have invested in additional printing machinery, rising electricity costs became something we wanted to get ahead of. DW Energy gave us clear advice and designed a solar and battery system that suited the way our site operates.
The installation was completed in just eight days and the team were excellent throughout. They kept everything on track, worked neatly and made sure the project was delivered without disrupting our operations.
We are already seeing the benefit of generating and storing more of our own electricity on site, and we’re now over 70% self-sufficient. DW Energy delivered on time, on budget and the standard of work was impeccable. We could not recommend them highly enough.”
