Slice 7 of the Solar PV Recommendation Generator (ADR-0026). Adds the composite per-dwelling Solar PV cost on the Products collection (ADR-0025 pattern): pv_system(kWp band, nearest of the ECOPV06-13 EA bands 1.0→4.5 kWp, floor/cap at the ends) + scaffolding(£900 first elevation + £450 each additional, default 2) + enabling base (EICR £150 + DNO £50 + 2-way consumer unit £330) + [diverter £980 if cylinder] + [battery if the with-battery variant] → Cost(total, contingency_rate 0.15). Rates are data in the committed solar_rates.json (Southern Housing "SOLAR PV & BATTERY" EA column), loaded via SolarRates.from_json/.default and injectable. The £2,000 / 5 kWh battery is NOT on the rate sheet — a flagged estimate (battery_estimate=true), confirmed with the user to stand in until a DB rate.
