Donegal Atlantic-cool climate yields ~850-950 kWh/kWp annually (the lowest in Ireland, vs 1,050-1,150 in the south-east). The yield is compensated by grant economics and pairing with heat pump and battery storage for self-consumption. State annual yield estimate on every quote based on Photovoltaic Geographical Information System (PVGIS) data for the specific F92 Eircode.

Yes, battery storage is more important in Donegal than anywhere else in Ireland because of the lower yield. Quote battery storage (Tesla Powerwall, BYD Battery-Box, Pylontech, GivEnergy) EUR 4,500-EUR 11,000 installed. State usable capacity (kWh), cycle warranty (5,000-10,000 cycles), and 10-year warranty. Pair with smart EV charger (Zappi, Easee) and air-to-water heat pump for full home energy management.

Per kW installed in {YEAR}: €865 to €1,800 in the US, £1,200-2,000 in the UK, A€650-1,800 in Australia, R18,000-35,000 in South Africa, and C€1,730-3,800 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 €215-1,500. Worth it on large projects.
