Case Study: Toyota, (Sidcup, Hyde, and Enfield)
In this case study, Geo Green Power details a successful multi-site solar rollout for Jemca, one of Britain’s largest Toyota and Lexus retailers.
To support Toyota’s ‘Environmental Challenge 2050’ goals, Geo Green Power installed a combined 272kWp of solar capacity across three dealerships in Sidcup, Hyde, and Enfield.
These systems generate approximately 250,000kWh of clean electricity annually, saving the group tens of thousands of pounds on energy bills while reducing carbon emissions by 186 tonnes per year, the equivalent of removing 37 petrol cars from the road.
The project provides Jemca with greater control over its energy costs and a significant boost to its sustainable retail credentials.
Complete Renewable Energy for Business
As leading specialists in commercial solar for London, we provide a holistic approach to energy that extends far beyond the rooftop.
Buffer your energy usage. Store the excess power generated by your commercial solar panels in London during the day to power your operations through the night or during expensive peak-tariff periods.
Maximise your parking assets. Our solar carports provide weather protection for staff and fleet vehicles while generating clean electricity, ideal for London businesses with large car parks but limited roof space.
Future-proof your fleet. We install smart, high-speed commercial EV charging points that integrate with your commercial solar power London array, allowing your fleet to run on “free” solar fuel.
Protect your investment. From drone thermal imaging to electrical string testing, our maintenance packages ensure your commercial solar energy London setup remains at peak efficiency for decades.

Regional Grants and Financial Incentives
London businesses can access several financial mechanisms designed to accelerate the transition to renewable energy and offset the initial capital expenditure of a solar installation.
At the local level, the Mayor of London’s Climate Investment Capacity (CIC) and various borough-specific initiatives, such as the Green Business Loan Scheme, often provide SMEs with access to low-interest financing or match-funded grants for carbon-reduction projects.
These regional supports are frequently updated to align with the “Net Zero London by 2030” target, helping businesses in high-cost areas like the City and Canary Wharf manage the upfront costs of London commercial solar energy projects while improving their ESG (Environmental, Social, and Governance) ratings.
UK-wide Financial Incentives
UK companies can significantly lower solar installation payback periods by deducting 100% of the costs from their taxable profits in the first year through the Annual Investment Allowance and Full Expensing rules. Additionally, the Smart Export Guarantee allows businesses to earn revenue by selling excess generated electricity back to the grid.
