Per kW installed in {YEAR}: $1,440 to $3,000 in the US, £1,200-2,000 in the UK, A$1,080-1,800 in Australia, R18,000-35,000 in South Africa, and C$2,880-3,800 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.
