The financial gain from energy savings compared to the initial installation cost, typically measured as a percentage over a specific period of time.
Return on Investment (ROI):
153.76%
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:
6.9 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:
£879.78
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:
£10,557.36
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:
£195,407

24kW
The amount of carbon dioxide (CO2) a solar power system prevents from being released into the atmosphere each year by replacing electricity generated from fossil fuels, measured in tons.
Annual CO2 Emissions Saved:
6.75t
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.
Dirt Driver, a British manufacturer specialising in the design, manufacture and production of heavy duty pressure washing equipment, wanted to boost its sustainability initiatives while cutting energy costs.
Project Scope:
Installation of a 40.8kW state-of-the-art solar photovoltaic (PV) system with three 10kWh Solar Edge batteries.
Solution Implemented:
Sunlit Solar designed and installed a custom solar PV array, with total storage capacity of 30kWh, for the company, maximising energy generation and reducing reliance on the grid.
Results Achieved:
Clean Energy Generation:
The installed solar PV system is projected to produce an estimated 34.88MWh of clean energy annually.
Carbon Emissions Reduction:
Dirt Driver expects to cut carbon emissions by 6.75 tons annually, in line with their commitment to environmental sustainability.
Operational Efficiency:
By utilising solar energy and battery storage, the company is set to reduce its dependence on traditional energy sources, resulting in long-term cost savings and improved operational efficiency.
