Solar for Housing Associations
Housing associations are major solar adopters — funded by SHDF and ECO4. Tenants get free electricity. Contact your HA about their solar programme.
Solar and Shared Ownership
Shared ownership: you may need housing association permission for solar. As part-owner, you have more rights than a tenant. Check your lease.
Solar and Right to Light
There is NO specific 'right to solar light' in UK law. Neighbours can build extensions that shade your panels without legal liability. What you can do.
Home vs EV Battery
Your EV has a 50-80kWh battery. Your home battery: 5-13kWh. With V2G, your EV could replace your home battery. But V2G is still emerging in the UK.
Solar and New Build Warranty
Adding solar to a new build within the NHBC warranty period: inform the builder. Properly installed solar does NOT void your NHBC or LABC warranty.
Solar for Victorian Houses
Victorian houses are excellent for solar: large rear roofs, slate tiles (compatible), generous space. Listed: may need consent. Conservation area: check front-facing rules.
Solar for 1930s Houses
1930s houses are ideal for solar: large hipped roofs, concrete tiles, structurally sound. Common UK housing stock with excellent solar potential.
Solar for 1960s Houses
1960s houses: concrete tile roofs, simple gable designs, adequate structure. Good solar candidates. Check for asbestos soffits/fascias before installation.
Solar for End-Terrace

Solar for Dental Practices
Dental practices use 15,000-30,000 kWh/yr (compressors, sterilisers, lighting, HVAC). A 10-30kW system saves £2,500-£6,000/yr. Fast 5-8 year payback.
Solar for Hair Salons
Hair salons spend £3,000-£8,000/yr on electricity (dryers, straighteners, lighting, HVAC). A 5-15kW system saves £800-£2,500/yr.
Octopus Agile and Solar
Octopus Agile: half-hourly variable pricing. Sometimes NEGATIVE (paid to use electricity!). With solar + battery: buy cheap/free, sell high. Advanced strategy.
Solar for Terraced Houses
Terraced houses: 6-8 panels (2.4-3.2kW) on the rear roof. Cost: £4,000-£6,000. Saves: £350-£650/yr. Scaffolding may need pavement licence.
Energy Audit Before Solar
An energy audit identifies waste before you install solar. Fix insulation, draught-proofing, and inefficient appliances first — then solar covers a smaller, optimised load.
