Which Georgian region has the best solar?

Telavi in Kakheti (4.1 PSH) is Georgia's sunniest wine region. Tbilisi and Rustavi (4.0 PSH) follow. Batumi (3.5 PSH) on the Black Sea is cloudiest. Even the cloudiest Georgian regions can achieve viable solar economics with net metering.

Is this for Georgia the country or Georgia the US state?

This calculator is for Georgia the Caucasus country (capital: Tbilisi), using Georgian Lari (GEL) and showing Energo-Pro/Telasi tariffs with prosumer net metering under Decree 46. For the US state of Georgia, see the US solar calculators section.

How to Use This Calculator

Enter your monthly bill and region

Enter your average monthly electricity bill from Telasi (Tbilisi) or Energo-Pro (regions) in Georgian Lari (GEL). Georgia's subsidized electricity tariff ranges from GEL 0.18–0.30/kWh (~€0.07–0.11), making it one of the lowest-cost electricity markets in the Caucasus. Select your region — Telavi in Kakheti (4.1 PSH) is Georgia's sunniest area, while Batumi on the Black Sea coast (3.5 PSH) is the cloudiest due to its subtropical climate. Note: this calculator is for Georgia the country — for the US state of Georgia, see the US state calculators.

Georgia's prosumer net metering (Decree 46, 2018)

Georgia introduced prosumer net metering under Government Decree No. 46 in 2018. Solar system owners can export surplus electricity to Telasi or Energo-Pro and receive credit at the retail rate — a 1:1 scheme. GNERC (Georgian National Energy and Water Supply Regulatory Commission) oversees the framework. USAID Energy Program and EU-funded initiatives have supported solar deployment in Georgia, particularly for SMEs and municipal buildings.

Kakheti wine country solar opportunity

Kakheti, Georgia's famous wine region around Telavi (4.1 PSH), is particularly well-suited for solar. Wine estates, agritourism properties, and guesthouses (sanapiro) have high daytime energy needs for cooling, processing, and hospitality operations. The combination of Georgia's highest solar radiation and productive agricultural land makes Kakheti a natural solar adopter. Several international wine producers have installed 8–30kWp systems.

The Formula

Monthly kWh = Monthly Bill ÷ GEL 0.23/kWh (blended Telasi/Energo-Pro rate) Annual production = kWp × PSH × 365 × 0.80 efficiency Self-consumption = Annual kWh × 40% Self-consumption savings = Self-consumed kWh × GEL 0.23/kWh Net metering export = Exported kWh × GEL 0.23/kWh (retail, Decree 46) System cost = kWp × GEL 3,000–4,500/kWp (~€1,100–1,650/kWp) Payback = Total cost ÷ Annual benefit (typically 8–12yr) EUR reference: 1 EUR ≈ GEL 2.73

Georgia's energy mix is predominantly hydroelectric (~80%), making it a naturally low-carbon grid. Solar complements hydro by providing summer peak generation when hydro availability is lower. The government's 2030 energy strategy includes targets for distributed solar. Georgia has attracted significant investment from USAID, EU4Energy, and EBRD for solar development, particularly in commercial and municipal sectors. Some regions also benefit from additional subsidy programs funded by development partners.

Example

Nino — Kakheti winery, 8kWp with net metering

Nino runs a wine estate near Telavi with a monthly Energo-Pro bill of GEL 350. She installs an 8kWp system to power the winery operations and guesthouse, registered under the prosumer scheme.

Kakheti's 4.1 PSH is Georgia's best solar resource. The net metering scheme improves economics significantly over self-consumption only. The main constraint is Georgia's very low electricity tariff (GEL 0.18–0.30/kWh), which extends payback. USAID Energy Program grants or EBRD green financing can reduce upfront cost for eligible businesses. The 25-year asset life makes solar a solid long-term investment even with longer payback.

FAQ

Is solar worth it in Georgia (the country)? ▼

Solar in Georgia (the Caucasus country) is viable but has longer payback (8–12 years) due to very low subsidized electricity tariffs (GEL 0.18–0.30/kWh, ~€0.07–0.11). The prosumer net metering scheme (Decree 46, 2018) helps by crediting exports at retail rate. Kakheti (4.1 PSH) offers the best solar production. USAID and EU programs sometimes offer grants or subsidized financing for businesses. Long-term (25 years), solar is a positive investment in almost all Georgian regions despite lower short-term returns.

How does prosumer net metering work in Georgia? ▼

Georgia's prosumer scheme (Government Decree No. 46, 2018) allows solar owners to connect to the grid and export surplus electricity at retail rate. Excess credits accumulate monthly. You register as a prosumer with GNERC, your installer connects your system through a certified process, and your distributor (Telasi for Tbilisi, Energo-Pro for regions) installs a bidirectional smart meter. The process is relatively straightforward by regional standards. GNERC's website (gnerc.org) has current registration requirements.

Which region of Georgia has the best solar? ▼

Telavi (4.1 PSH) in Kakheti wine country is Georgia's sunniest region. Tbilisi and Rustavi (4.0 PSH) are close behind. Gori (3.9 PSH) and Kutaisi (3.8 PSH) are good. Borjomi (3.6 PSH) in the mountains receives less. Batumi (3.5 PSH) on the Black Sea coast is the cloudiest — Georgia's subtropical Black Sea climate brings significant rainfall and cloud cover to Adjara. Even Batumi can achieve viable solar economics given the net metering scheme.

Are there solar subsidies in Georgia? ▼

Georgia does not have a large direct residential solar subsidy program, but several programs provide indirect support: USAID Energy Program has funded solar installations for SMEs and public buildings; EBRD (European Bank for Reconstruction and Development) offers green economy finance through Georgian banks; EU4Energy program supports energy efficiency and renewables; some municipalities have supported solar on public buildings. For residential users, the primary benefit is the prosumer net metering scheme under Decree 46. Check with the Georgian Renewable Energy Association (GREA) for current programs.
