Estimates only. Output uses PVGIS 5.3 yields for each location (optimal fixed tilt, 14% losses). Savings assume net metering, where each kWh you produce offsets a kWh you would buy, at GNERC tariffs valid from 1 July 2026 to 1 January 2027; business savings exclude 18% VAT. Prices are average installed prices per kW in Georgia, converted at 2.60 GEL per USD. Systems connected from 1 January 2027 move to net billing, which values exported power lower.
How the calculator works
- It takes your annual use (monthly use × 12) and divides it by the expected output of 1 kW of panels in your city, from the EU's PVGIS model.
- It prices the system with average installed prices in Georgia, from about $750 per kW for 1 kW down to about $350 per kW at 500 kW.
- It values each kWh at your tariff: the household tariff bands in Tbilisi or the regions, or the small business tariff.
- Payback is the installed cost divided by the annual savings, before financing, maintenance and inverter replacement.
Frequently asked questions
How many solar panels do I need for my house in Georgia?
Divide your annual electricity use by about 1,200–1,350 kWh, the yearly output of 1 kW of panels in most of Georgia. A household using 300 kWh a month (3,600 kWh a year) in Tbilisi needs about 2.8 kW, or six to seven panels of 450 W.
How much does a 5 kW solar system cost in Georgia?
About $650 per kW installed, so roughly $3,250 (about 8,500 GEL) for a complete 5 kW rooftop system, depending on equipment and the roof.
How long does solar take to pay back in Georgia?
Businesses that use power in the daytime usually pay back in about 3–5 years, because they pay about 35 tetri per kWh. Households pay less per kWh, so payback is usually longer.
What is the largest system I can connect under net metering?
500 kW per micro power plant. Larger plants sell through the wholesale market or contracts.
