⚠ Day Ahead Market arbitrage adjustment applied. This system's export kWh (0 kWh) exceeds its annual solar generation (0 kWh), meaning 0 kWh of the reported export represents grid-charged battery cycling rather than solar export. A grid charging cost of 7p/kWh has been deducted from the optimised export income to reflect the net position. Surveyor note: please verify the export figure with the energy audit figures before presenting to the customer.

Baseline figures sourced from commercial energy audit. Sentinel Pro uplift figures are estimates based on system size, battery capacity, operational profile, tariff type, and Intelligent Energy Partner commercial BESS scenario benchmarks (March 2026). Market revenues are not guaranteed and may be subject to a c.12 month delay for Capacity Market registration. Ancillary services require enhanced metering and may not be available immediately. Market revenues shown net of 20% Intelligent Energy Partner trading fee and 20% Sentinel optimisation fee. Where a Day Ahead Market tariff is selected and the reported export kWh exceeds annual solar generation, a grid charging cost of 7p/kWh is deducted from the optimised export income to reflect the net cost of grid-charged battery arbitrage cycles. Sentinel Pro subscription deducted from year 2 onwards. Energy price inflation applied at 7% per annum to cumulative projections. This calculator is a sales support tool for HSEnergy commercial surveyors and should not be presented to customers as a guaranteed financial forecast.
