A measure of how efficiently a solar system converts sunlight into usable electricity. It’s the ratio of actual energy output to the system’s theoretical maximum output, as a percentage.
Performance Ratio:
89%
The time it takes for a solar panel system’s energy savings to equal the initial installation cost. It’s calculated by dividing the total cost by annual savings from reduced energy bills.
Estimated Payback Period:
2 Years
The predicted amount of money a household or business saves on energy bills each month after installing a solar power system, based on energy production.
Estimated Monthly Bill Saving:
£4,920.77
The predicted amount of money a household or business saves on energy bills annually after installing a solar power system, based on energy production.
Estimated Annual Bill Saving:
£59,049.24
The total amount of money saved on energy bills over the entire lifespan of a solar system, accounting for installation costs and energy production.
Estimated Net Lifetime Bill Saving:
£1,315,879

Annual CO2 Emissions Saved:
42.25t
The number of trees needed to absorb the same amount of CO2 emissions that a solar power system prevents each year, illustrating the environmental benefit in tree terms.
Haynes Motor Museum, sought to enhance its sustainability efforts while reducing operational costs.
Project Scope:
Installation of a 240kW state-of-the-art solar photovoltaic (PV) system
Solution Implemented:
Sunlit Solar designed and installed a custom solar PV array for the museum, maximising energy generation while seamlessly integrating with its architecture.
Results Achieved:
Clean Energy Generation:
The installed solar PV system is projected to produce an estimated 218.46MWh of clean energy annually.
Carbon Emissions Reduction:
Haynes Motor Museum anticipates a significant reduction of 42.25 tons in carbon emissions per year, aligning with their commitment to environmental sustainability.
Operational Efficiency:
By harnessing solar energy, the museum is poised to decrease its reliance on conventional energy sources, leading to long-term cost savings and operational efficiency.
