Per kW installed in {YEAR}: £720 to £1,500 in the US, £1,200-2,000 in the UK, A£540-1,800 in Australia, R18,000-35,000 in South Africa, and C£1,440-3,800 in Canada. Larger systems get cheaper per-kW due to scale; tier-1 panels and premium inverters push toward the top.
Most 3-bed homes need 5-8kW; 4-bed+ homes with pool or EV need 8-12kW. Look at your last 12 months of electricity bills, divide annual kWh by 1,300 (Australia/SA), 950 (UK/Canada), or 1,200 (US average). That gives kW capacity to offset most of your bill.
Depends on your feed-in tariff. Where FIT is high (Australia historically), batteries have 10-12 year payback; export to grid is more valuable. Where blackouts are common (South Africa) or FIT is low (UK), batteries pay back faster and add resilience. Quote both options.
A standard 5-10kW residential install is 1-2 days on the roof for a 3-person team, plus grid connection paperwork (1-6 weeks depending on utility). Larger systems and commercial installs take 3-7 days.
Site visits and verbal quotes for systems over 4kW are usually free. A detailed shading analysis, structural roof report, and load-flow calc for a 20kW+ commercial system takes 4-8 hours and may be charged £180-1,500. Worth it on large projects.
