Solar panels in Mardakan: 2026 payback calculation
Absheron gets 2,950-3,100 sunshine hours a year — the highest in the region. A 5-10 kW rooftop system pays back in 4-6 seasons and adds 30-50k AZN to house value. Legal scheme and 2026 prices.
1. Absheron — perfect region
Data: 2,950-3,100 sun hours/year, solar irradiance 5.2 kWh/m²/day. That is 40% above Germany, at Greek levels. 1 kW yields 1,400-1,550 kWh/year. 5 kW covers 60-90% of a family home's demand.
2. System size
Real choice: 3 kW — small house, bill 40-70 AZN; 5 kW — family villa, 80-140 AZN; 8 kW — pool + AC, 150-280 AZN; 12 kW — premium + spa. System cost 1,800-2,400 AZN per kW. 5 kW — 9,000-12,000 AZN.
3. Grid connection — net-metering
Azerbaijan has net-metering since 2019: surplus flows into the grid and credits your account. Procedure: 1) «Azerishig» application (10 working days); 2) technical conditions (20-30); 3) install (5-10); 4) verification and connection (7-14). 2-3 months total. Fee 200-500 AZN.
4. Real payback
5 kW system, install 10,500 AZN. Annual output 7,400 kWh, avg 620 kWh/month. Savings 90-140 AZN/mo, 1,200-1,700 AZN/year. Payback 6-9 years. Next 15-20 years — free power. House-value uplift — 28-42k AZN.
5. Battery — needed or not?
Absheron power is fairly stable (25-40 outages/year). Battery Tesla Powerwall or BYD (10 kWh) — 8,000-14,000 AZN, payback 12-15 years. Without battery with net-metering is usually better. Batteries only pay off in remote zones with frequent outages.
Solar — size and payback
| Size | Price | Annual saving | Payback |
|---|---|---|---|
| 3 kW | 5,500-7,200 AZN | 700-1,000 AZN | 6-8 yrs |
| 5 kW | 9,000-12,000 AZN | 1,200-1,700 AZN | 6-9 yrs |
| 8 kW | 14,500-19,000 AZN | 1,900-2,700 AZN | 6-8 yrs |
| 12 kW | 21,500-28,000 AZN | 2,850-4,050 AZN | 6-8 yrs |
Solar panels are a 20-year deposit for a house. Put in 10,500 AZN, earn 15-18% p.a. (vs 8-9% bank deposit). Plus +30-50k AZN to house value — no bank matches that.
