Save money with trusted commercial solar solutions.
Below, our commitment to sustainability and high-quality commercial solar solutions is shown through our various case studies and installations. We've dedicated ourselves to reducing carbon footprints and promoting renewable energy, resulting in successful projects across residential and commercial sectors.
Our solar solutions have significantly impacted commercial entities, such as ADC Electrical in Washington (installed in Spring 2023). Committed to minimising their environmental footprint and reducing their energy bills, ADC Electrical instructed us to install a 38.88 kW solar system featuring the latest 540W Sharp Solar PV panels and a substantial 50kW 3-phase inverter complete with WiFi monitoring. They have plans to add more panels in the future, so they decided on a larger inverter to prove their investment.
This 38.88kW system will generate an average of 32,543 kWh per annum. At a price of 34p per kWh of electricity, that energy has a value of over £11,000, which would be produced yearly for the system's lifespan.
We believe in fostering a culture of environmental consciousness and sustainability among the younger generation. Our collaboration with Darlington College is a testament to this mission.

The Smart Export Guarantee (SEG) allows businesses with solar photovoltaic (PV) panels to monetise excess energy by selling it back to National Grid suppliers. Your enterprise can operate as both a consumer and a supplier of clean power. SEG licensees pay businesses a set rate for surplus energy. Rates may vary, but they will never fall to zero. With a smart meter in place, you can track the value of your energy in real-time and shop around for the most competitive deal.
Alongside SEG, UK businesses can also benefit from capital allowances (deducting installation costs from taxable profits) and in some cases regional grants (for example, the BEST Programme in the North East), making commercial solar an even smarter investment.
The Business Energy Saving Team (BEST) is a North East initiative helping small and medium-sized businesses reduce energy costs and carbon emissions. Funded by the UK Government, the scheme offers free energy assessments and grant funding of up to 50% for eligible projects across Newcastle, Northumberland, North Tyneside, and Gateshead.
Grants can support many improvements, including solar PV systems. Funding is based on technology type and location, with contributions of up to £25,000 available for qualifying installations. Businesses across the region are already seeing the benefits. One example is the energy-saving upgrade we did at Phillips Pet Supplies, where substantial improvements were made under the scheme. This is becoming increasingly common as more companies look to future-proof their buildings while managing overheads.
