Watt Solar Solution

Watt Solar Solution: solar energy for businesses and homes in the UK

Watt Solar Solution is a British company dedicated to the design, installation and maintenance of solar PV energy systems, battery storage and electric vehicle chargers. Its activity is aimed at both commercial and residential clients, with the goal of reducing electricity bills through customised solutions.

The company was founded by a finance director and an energy expert, and has its own installation team. Its approach combines financial expertise and technical knowledge: each proposal is prepared as a business case, using financial metrics to size systems that prioritise profitability and a tight return on investment.

Design and installation services

Watt Solar Solution offers an end-to-end service covering everything from technical and financial design through to installation, commissioning and certification. The process begins with a site assessment, structural review and performance analysis. From there, the electrical design is carried out in accordance with G98/G99 regulations, inverters are selected and battery capacity is sized according to the client's consumption profile and energy goals.

The installation includes solar PV panels, storage systems and electric vehicle charging infrastructure. The company also handles integration with monitoring platforms and building management systems. All work is carried out by professionals accredited under NAPIT, MCS, RECC and TrustMark certifications, which guarantees compliance with current UK standards.

Maintenance and optimisation

The company offers operation and maintenance (O&M) packages for both new and existing systems, including those installed by third parties. These services include scheduled annual inspections, performance testing, electrical safety checks (insulation resistance, continuity, earthing, RCD and SPD), inverter and battery health checks (SoH, DoD and firmware updates), monitoring platform management and alert resolution.

For commercial systems, Watt Solar Solution offers standard and enhanced service levels, which can include remote monitoring, guaranteed response times and corrective maintenance options. Detailed reports include photographs, performance benchmarking and regulatory compliance updates.

Export tariff support

Watt Solar Solution helps solar system owners secure more competitive energy export contracts than standard Smart Export Guarantee (SEG) tariffs. The team works with energy partners to connect clients with advantageous export agreements, which can be set up independently of their current electricity supplier. This service includes reviewing existing agreements, tariff analysis, negotiating higher-rate contracts, setting up metering and data verification, and ongoing support with contract management and renewals.

Technical and financial profile

One of the co-founders is a Chartered Accountant (ICAEW), which brings a rigorous financial approach to every proposal. The Head of Operations is a qualified electrician with decades of experience in the design and installation of large-scale commercial solutions. The management team has been involved in the development of solar systems totalling more than 1.5 MW and has experience across the energy, engineering and financial sectors.

The company presents itself as a full-service partner that does not subcontract installations, but carries them out with its own team. Its systems are sized and modelled using real electricity consumption and roof space data, and site visits are carried out where necessary to confirm assumptions. For clients paying cash, the return on investment is typically between 2 and 5 years; with financing, monthly savings can exceed repayments, generating positive cash flow from day one.

Accreditations and local commitment

Watt Solar Solution holds NAPIT, RECC, MCS Certified, EVCC, IWA Waste Carrier Licensed, ICAEW and TrustMark accreditations, which support its ability to carry out the services it offers safely and in compliance with regulations. The company has also launched an initiative to support Yorkshire Children's Charity, which includes donating five full days of its operation and maintenance package to commercial businesses, in exchange for a minimum donation of £1,500 to the charity.
