Solar for 1930s Houses

Are 1930s houses good for solar?

1930s houses are among the best UK properties for solar: (1) LARGE ROOF AREAS — 1930s semis and detacheds have generous roofs. Hipped roofs may have two suitable faces (south + east/west). (2) CONCRETE TILES — most 1930s roofs have concrete tiles (original or replaced). Standard tile hooks work perfectly. Cheapest roof type for solar. (3) STRUCTURAL STRENGTH — 1930s roofs use substantial timber rafters. Easily supports solar panels. (4) ORIENTATION — many 1930s estates were built with houses oriented east-west (front/back), giving south or near-south rear roof faces. (5) NO LISTING CONCERNS — 1930s houses are rarely listed. Standard permitted development applies. (6) TYPICAL SYSTEM: 10-14 panels (4-5.6kW) on the rear roof. Cost: £5,500-£8,000. Saves: £580-£1,000/yr. CONSIDERATION: original 1930s wiring may need updating. Check consumer unit capacity during survey.
