Is solar worth it in Mongolia?

Absolutely for off-grid herders — Mongolia has over 260 sunny days per year and off-grid solar replaces expensive diesel generators with payback as short as 2–4 years. For grid-tied urban systems, low subsidized grid tariffs (100–300 MNT/kWh) extend payback to 10–15 years. Western Mongolia (Olgii, 5.2 PSH) has the best solar resources.

How does solar work for Mongolian herders?

About 40% of Mongolia's population lives nomadically in gers (yurts) without grid access. Small solar kits (0.5–2kWp) with battery storage power LED lighting, phone charging, TV, and a small refrigerator. The Mongolian government and international organizations (World Bank, ADB) have subsidized hundreds of thousands of herder solar kits since 2000. Cost is typically $500–1,500 for a complete kit.

What are Mongolia's solar energy policies?

Mongolia's Renewable Energy Law (2015) set a target of 30% renewable energy by 2030. Grid-connected solar can sell surplus to the grid at regulated feed-in tariffs, though rates are low compared to retail. The government's 100,000 Solar Ger program electrified nomadic households across rural Mongolia using photovoltaic kits.

Which region gets the most sun in Mongolia?

Olgii in the Bayan-Olgii province (5.2 PSH) is Mongolia's sunniest region due to high altitude and arid western climate. Khovd (5.0 PSH) and Choibalsan (4.8 PSH) in the east are close behind. Ulaanbaatar (4.5 PSH) has shorter winter days but produces excellent summer yields. Mongolia overall receives significantly more solar radiation than most of Europe.

How to Use This Calculator

Enter your bill and city

Enter your average monthly electricity bill in Mongolian tugrik (MNT). For off-grid herder calculations, enter 0 as your bill — the calculator switches to diesel cost savings mode. Select your city or region: Olgii in western Mongolia (5.2 PSH) is the sunniest region in the country due to its high altitude and arid climate. Ulaanbaatar (4.5 PSH) has shorter winter days but produces good summer yields thanks to Mongolia's 260+ sunny days per year.

Grid-tied vs off-grid herder context

Toggle "Off-grid herder context" for nomadic ger (yurt) households. About 40% of Mongolia's 3.3 million population lives nomadically without grid access. Small solar kits (0.5–2kWp with battery) replace diesel generators and power LED lighting, phone charging, a small TV, and a refrigerator. The economics are compelling: diesel fuel costs equivalent to MNT 800/kWh in remote areas, making solar payback 2–4 years versus 10–15 years for grid-tied urban systems.

Grid-tied systems

For urban grid-connected systems, surplus solar production can be exported at regulated feed-in tariffs (approximately 60 MNT/kWh). Self-consumption at 100–300 MNT/kWh retail is far more valuable. Mongolia's low subsidized grid tariffs extend payback periods for urban systems, but the country's strong solar resource partially compensates.

The Formula

Annual production = kWp × PSH × 365 × 0.80 efficiency Grid-tied self-consumption = Annual kWh × 50% Self-consumption savings = Self-consumed kWh × MNT 200/kWh retail Feed-in income = Exported kWh × MNT 60/kWh (low grid tariff) Off-grid diesel savings = Annual kWh × MNT 800/kWh diesel equivalent System cost (grid-tied) = kWp × MNT 3,500,000–5,000,000/kWp Off-grid kit cost = MNT 1,750,000–5,250,000 (~$500–1,500) Payback = Total cost ÷ Annual benefit (off-grid: 2–4yr, grid: 10–15yr)

Mongolia's Renewable Energy Law (2015) targets 30% renewable energy by 2030. The government's 100,000 Solar Ger program, supported by the World Bank and Asian Development Bank, has electrified hundreds of thousands of nomadic households. Grid-connected solar regulation falls under the Energy Regulatory Commission of Mongolia (ERC), with feed-in tariffs set by the Ministry of Energy.

Example

Bataar — Herder family, Khovd, 0.5kWp off-grid kit

Bataar's family lives in a ger near Khovd. They currently spend the equivalent of MNT 15,000/month on diesel for their generator. They install a 0.5kWp solar kit with battery storage.

Location / PSHKhovd, 5.0 PSH

System size0.5 kWp

ContextOff-grid herder

Result

Annual production~730 kWh/yr

Diesel savings~MNT 584,000/yr

Kit cost~MNT 1,750,000–2,100,000

Payback~3.2 years

25-year net savings~MNT 12,685,000

At 5.0 PSH, Khovd's solar resource allows a small 0.5kWp kit to replace most of a herder family's diesel consumption. The kit pays back in about 3 years and provides 25 years of clean energy. Many Mongolian herders report the elimination of generator noise and fuel transport as significant quality-of-life improvements.

FAQ

How does solar work for nomadic Mongolian herders? ▼

Mongolian herder solar kits typically include 2–4 solar panels (0.25–0.5kWp total), a 12V battery (50–100Ah), a charge controller, an LED lighting kit, phone charging sockets, and sometimes a small DC refrigerator. The kits are designed to be portable — herders move their gers seasonally, and panels are mounted on simple frames that can be relocated. The Mongolian government's 100,000 Solar Ger program distributed over 100,000 subsidized kits between 2000 and 2010, transforming rural electrification.

Is grid-tied solar viable in Ulaanbaatar? ▼

Grid-tied solar in Ulaanbaatar is viable but has a longer payback (10–15 years) due to Mongolia's low subsidized electricity prices (100–300 MNT/kWh). Ulaanbaatar's severe air pollution from coal heating provides additional motivation — solar reduces dependence on coal-based power. Mongolia's 4.5 PSH in Ulaanbaatar is decent, with summer months producing excellent yields. Winter production drops significantly due to short days and snow, but Mongolia's cold-clear winter air actually improves panel efficiency when production occurs.

What does solar cost in Mongolia? ▼

Off-grid herder solar kits cost approximately MNT 1,750,000–5,250,000 ($500–1,500) for complete 0.5–2kWp systems including battery and charge controller. Grid-tied residential systems cost MNT 3,500,000–5,000,000 per kWp installed (~$1,000–1,500/kWp). Mongolia imports most solar equipment from China, keeping costs competitive. The government and international development organizations (World Bank, ADB, GCF) periodically subsidize rural solar installations.

Does solar work in Mongolia's extreme winters? ▼

Yes, with caveats. Mongolia's winters are extreme (−40°C in Ulaanbaatar), but solar panels actually perform better in cold temperatures when sunlight is available. The main challenges are short winter days (8–9 hours) and occasional snow covering panels. Modern panels shed snow quickly when installed at steeper tilt angles. Battery performance degrades below −20°C, so lithium iron phosphate (LFP) batteries are recommended over lead-acid for Mongolian winters. Summer months provide abundant surplus production that can offset winter shortfalls in net metering arrangements.
