Project Summary
Orange Solar Systems designed and quoted a high efficiency 2.7 kW solar PV system for a residential property located in Calmore, Southampton. The objective of this installation is to lower reliance on grid electricity, reduce household energy bills, and cut carbon emissions through clean renewable energy. The pitched roof array faces south-west at an orientation of 60 degrees from south with a pitch of 35 degrees, benefiting from zero shading.
System Components
The installation features six Trina Vertex S+ 450W Dual Glass Full Black N-Type Mono solar panels paired with a Fox ESS F Series (G3) 3kW single-phase dual MPPT string inverter. The system is mounted using a Renusol pitched roof mounting system specifically designed for concrete tile roofs. Orange Solar Systems includes a complete electrical safety bundle, including isolators, cabling, generation metering, and standard certification.
Performance & Energy Breakdown
The system is estimated to generate 2,481 kWh per year against an assumed annual property consumption of 3,100 kWh. Direct self-consumption accounts for 838 kWh per year, meaning 27% of the home’s energy needs are met directly by solar power. The property will export 1,643 kWh of excess electricity back to the grid each year while importing 2,262 kWh during non-generating periods.
Financial Overview
The total installation cost is £3,500.00 inclusive of 0% VAT. Estimated first-year savings stand at £456, combining £209 in direct bill reductions with £246 earned through export tariffs. The project offers an estimated payback period of 8 to 9 years and a projected cumulative discounted benefit of up to £9,990 over 25 years.
Environmental Impact
By generating clean electricity on site, the installation yields annual carbon savings of 514 kg of CO2. This environmental reduction is equivalent to driving 1,835 miles in an average diesel car or the carbon absorption capacity of 24 trees every year.
