Is WFH + solar a good combination?

Excellent — home workers achieve 50-70% self-consumption (vs 30-40% for commuters). You're using electricity exactly when solar is generating. This is one of the best financial combinations for solar.

What about the space heater?

Space heaters (1-2kW) are the biggest home office load. On a sunny winter day: your solar may not cover it (low output). Options: use a lower-wattage heated blanket (100W), heated desk pad (60W), or infrared panel (300W). All more solar-friendly.

Can I claim solar as a business expense?

If self-employed: you can claim a proportion of electricity costs (including the solar benefit) as a business expense. The proportion is based on hours worked at home vs total hours. Consult your accountant.

Can solar power a home office?

Solar panels and home office electricity: TYPICAL HOME OFFICE CONSUMPTION: Laptop: 30-65W (0.2-0.5 kWh/day). External monitor: 20-40W (0.15-0.3 kWh/day). Router/broadband: 10-15W (0.24 kWh/day, 24/7). Desk lamp: 5-10W. Printer: 5-10W (standby). Space heater: 500-2,000W (biggest load — use sparingly). TOTAL (without heater): 500-800 kWh/yr. TOTAL (with heater 4hrs/day in winter): 1,000-1,500 kWh/yr. SOLAR COVERAGE: A 4kW system generates 10-20 kWh/day in summer — your entire office uses 1-5 kWh/day. Solar covers 100% of home office electricity during working hours (9am-5pm). SAVINGS: £120-£370/yr on home office power. Plus: higher solar self-consumption because you're home using electricity during peak solar hours.
