Slice 6 of the Solar PV Recommendation Generator (ADR-0026). `recommend_solar`
emits one "Solar PV" Recommendation of up to five conservatively-sized configs
× {no battery, battery} = ≤10 competing Options (a free Optimiser candidate).
Each Option folds a SolarOverlay built from the chosen config: one
PhotovoltaicArray per non-north segment (peak_power = panels × panelCapacityW /
1000; orientation/pitch from geometry; generation-calibrated overshading),
is_dwelling_export_capable set True absolutely, a diverter when the dwelling
has a cylinder (None for a combi), a 5 kWh battery for the battery variant, and
the per-config composite cost from Products.solar_bundle_cost.
Eligibility = house/bungalow ∧ not listed/heritage (blocks_internal, the same
gate as ASHP — a conservation area does NOT block PV) ∧ no existing PV ∧ a
feasible SolarPotential. Flats and existing-PV top-up are deferred.
