Quick Answer
Nepal's 2026 solar incentives are a policy stack rather than a single rebate: net billing for rooftop exports at NPR 5.94/kWh, a 50% interest subsidy for C&I rooftop solar through AEPC, 1% customs duty on solar/wind project equipment, VAT exemptions on qualifying imports, and a FY 2026-27 target of 370 MW of new solar capacity.
Nepal’s electricity sector is still dominated by run-of-river hydropower, but solar is no longer a rural lighting afterthought. By early 2026, total installed electricity capacity had reached roughly 3,243 MW, with solar contributing about 120 MW, according to Nepal’s Energy Development Roadmap 2024 as reported by ClimateWatch (2026). The government’s Third Nationally Determined Contribution, approved in 2025, now targets 14,031 MW of renewable electricity capacity by 2030 and 28,500 MW by 2035, with solar specifically earmarked for schools, hospitals, industries, and local government buildings.
For installers, EPCs, and business owners, the opportunity is real but the incentive stack is different from markets with large tax credits or feed-in tariffs. Nepal offers a mix of net billing for exports, concessional import duties, VAT exemptions, and AEPC-backed interest subsidies. The trick is knowing which mechanism applies to which project type and how to avoid the policy traps that waste money.
This guide covers the 2026 legal framework, the active incentives that cut project cost, how NEA compensates rooftop exports, and the mistakes that erode returns.

Latest Updates: Nepal Solar Incentives 2026
The Nepali solar policy environment shifted in 2025-26. The Third NDC raised renewable targets, the FY 2083/84 budget increased the energy allocation to NPR 85.54 billion, and the government signalled a move toward solar-plus-storage and green hydrogen. At the same time, the core rooftop export rate remained at NPR 5.94/kWh and the 500 kW net metering cap stayed in place.

Key Changes Since 2025
Third NDC, approved 2025: Nepal’s updated Nationally Determined Contribution targets 14,031 MW of renewable electricity capacity by 2030 and 28,500 MW by 2035, with solar given explicit roles in schools, health institutions, industries, and local government facilities, according to ClimateWatch (2026).
FY 2083/84 budget, May 2026: The energy sector received NPR 85.54 billion, the largest allocation in recent history. The budget targets 370 MW of new solar, a 100 MW battery storage system in Kathmandu, and a 2.5 MW green hydrogen pilot in Hetauda, according to Nepal Energy Forum (2026).
NEA unbundling: The budget proposes splitting the Nepal Electricity Authority into separate generation, transmission, and distribution/trade companies. If implemented, this could simplify grid connection and open private electricity trading.
Key Takeaway
2026 is a transition year. The most reliable incentives are the AEPC interest subsidies and import-duty relief, while net billing export value remains modest. Size systems for self-consumption first, export second.
Why Nepal’s Solar Market Matters in 2026
Nepal receives sunshine for more than 300 days a year and has a specific solar generation potential above 1,300 kWh/kWp/year in many areas, according to Urjakhabar (2025). That is better than many European markets that have already deployed gigawatts of solar.
Market Size and Targets
Total installed electricity capacity reached about 3,243 MW by 2024, with solar contributing roughly 120 MW, according to ClimateWatch (2026). Hydropower still supplies over 90% of grid capacity, which makes the system vulnerable to dry-season shortfalls and climate-related water variability.
The government’s targets are ambitious. Nepal aims to generate 25,944 MW of electricity by 2033/34, with 5-10% coming from solar and green hydrogen, and the Third NDC sets 14,031 MW of renewable capacity by 2030, according to ClimateWatch (2026). Solar is seen as a fast-deploying complement to hydropower, especially because solar output peaks in the dry season when reservoir levels are low.
Cost Advantage Over Hydropower
A megawatt of solar in Nepal costs roughly NPR 80-100 million, while hydropower can exceed NPR 200 million per megawatt and take two to three years longer to build, according to ClimateWatch (2026). For factories, hospitals, and institutions with daytime loads, rooftop solar can undercut NEA retail tariffs and provide backup during grid fluctuations.
For solar professionals, the design priority is to match generation to daytime load. A tool that models hourly consumption and solar production can show the real savings. SurgePV’s generation and financial tool is built for exactly that.
Net Metering and Net Billing Under NEA Rules
Nepal’s grid-connected solar framework started with the Ministry of Energy, Water Resources and Irrigation’s Grid-connected Alternative Energy Working Procedure 2074 (2018). It originally allowed net metering for rooftop systems from 500 W to 10 kW, community and corporate systems from 10 kW to below 1 MW, and larger commercial systems above 1 MW, according to GIZ (2024).
What Actually Applies in 2026
The implementing regulation limited system size to a maximum of 500 kWp and was initially valid for five years until July 2022. It was reinstated in February 2023, but the compensation was reduced from NPR 7.30/kWh to NPR 5.94/kWh, according to GIZ (2024). This means most practical rooftop projects today fall under a net-billing arrangement rather than true retail-rate net metering.
How Net Billing Works
Under the current rules:
- Solar generation first offsets on-site consumption.
- Any surplus is exported to the NEA grid.
- NEA credits the export at NPR 5.94/kWh.
- Grid imports continue to be billed at the customer’s normal retail tariff.
- The arrangement is generally available for systems up to 500 kW.
Because the export rate is below most retail tariffs, the financial return depends heavily on the self-consumption ratio. A factory that uses 80% of its solar generation on site will save much more than one that exports 50%.
Sizing Rule
The standard design rule in Nepal is the same as in other net-billing markets: size the system so that annual solar generation is close to annual on-site consumption, not to maximum roof capacity. Oversizing for export drops the effective value of every surplus kilowatt-hour from the retail rate to NPR 5.94.
A well-modelled solar design platform can test the system size against the customer’s actual load profile and show whether a project should stay under the 500 kW cap or move to a PPA route.
Tax and Customs Incentives
Nepal does not offer a direct income-tax credit for solar buyers. The real fiscal value lies in concessional import duties and VAT exemptions on qualifying equipment.
Customs Duty Relief
For solar and wind projects, construction equipment, machinery, tools, high-capacity batteries, steel sheets, and related raw materials can be imported at only 1% customs duty, on the recommendation of the Alternative Energy Promotion Centre or the Department of Electricity Development, according to the NBSM Nepal Budget 2082-83 Highlights (2025) and Crowe Concise Tax Update (2025).
Finished solar panels also benefit from a preferential customs duty structure, with solar cells attracting a 1% duty, although raw materials such as tempered glass and aluminium frames can face higher rates, according to PV KnowHow (2026). This tariff design favours module assembly inside Nepal over full component manufacturing.
VAT Exemptions
VAT exemptions apply in several cases:
- Goods used to generate electricity from imported solar energy, on AEPC recommendation.
- Solar thermal energy equipment under specified HS codes.
- Construction equipment, machinery, tools, batteries, steel sheets, and raw materials used for electricity generation, transmission, and distribution from water, solar, or wind projects, on DOED recommendation.
These provisions are detailed in the Crowe Concise Tax Update (2025).
Excise and Green Tax
The FY 2082-83 budget also exempted excise duty on machinery, high-capacity batteries, and raw materials for solar and wind projects. The FY 2083/84 budget introduced a new Green Tax that consolidates previous infrastructure and road maintenance levies at customs, but it also continues to direct tax and customs support toward strategic green industries, according to Nepal Energy Forum (2026).
For importers and EPCs, the practical step is to secure the correct recommendation letter from AEPC or DOED before shipment. Without it, equipment may be assessed at standard duty and VAT rates.
AEPC Subsidies and Challenge Funds
The Alternative Energy Promotion Centre is Nepal’s national focal agency for renewable energy. It runs several programmes that directly reduce the cost of solar projects.
DKTI C&I Rooftop Programme
Under the Promotion of Solar Energy in Rural and Semi-urban Regions of Nepal (DKTI), funded by the German government through KfW, AEPC targets 15 MW of on-grid solar rooftop systems for commercial and industrial entities. The support mechanism is a 50% interest subsidy for five years, as provided in the Renewable Energy Subsidy Policy 2022, according to AEPC (2022).
Nepal Renewable Energy Programme
With financial support from the British Embassy in Kathmandu, AEPC offers two support options for captive-use projects under 1 MW:
- A maximum of 50% of the total loan interest for up to five years, or
- A maximum of NPR 1.50 per unit generated for up to five years.
The applicant chooses the option that fits the project, according to Urjakhabar (2025).
Off-Grid and Irrigation Support
AEPC also provides capital subsidies for off-grid applications:
- Small individual solar irrigation pumps: up to 60% investment subsidy, capped at NPR 2 million.
- Large community solar irrigation pilots: up to 80% subsidy.
- Solar mini-grids for local governments: up to 90% subsidy, with the local body contributing 10%.
These figures are from AEPC (2022).
For solar professionals, the takeaway is that the easiest money in Nepal is not a direct panel subsidy. It is low-cost debt backed by AEPC interest subsidies, combined with customs and VAT relief.
Commercial, Industrial, and Utility-Scale Solar
C&I solar is the fastest-growing segment in Nepal. Factories, hospitals, and institutions use solar to cut daytime power purchases and protect against voltage fluctuations.
Real-World Example: Devdaha Medical College
Devdaha Medical College in Rupandehi installed a 600 kW rooftop system. It now saves roughly NPR 600,000 to NPR 700,000 per month because solar costs about NPR 8.30 per unit compared with NEA tariffs around NPR 13 per unit, according to ClimateWatch (2026). The college plans to expand solar to cover all rooftops and meet daytime demand.
The 500 kW Cap
One of the most complained-about barriers is the 500 kW limit for grid-connected rooftop solar. Nivesh Agrawal of Maruti Papers and Chemicals Industries noted that factories often want to install 5-6 MW but cannot connect surplus generation above 500 kW to the grid, according to ClimateWatch (2026). This forces larger consumers to either waste surplus or pursue a full PPA route.
Utility-Scale PPAs
NEA issued a major tender in 2024 for roughly 800 MW of grid-connected solar and eventually allocated about 960 MW under 25-year power purchase agreements, according to Bhandari (2026). The ceiling tariff was NPR 5.94/kWh. Developers have questioned whether this rate is viable at commercial lending rates of 12-13%, and some winning bidders have reportedly sought viability-gap funding from development partners, according to GIZ (2024).
For C&I installers, the design priorities are different from residential work. Load profiling, demand-charge analysis, and shadow analysis matter more than simple bill offset. SurgePV’s solar proposal software can package these numbers into a clear customer-facing document.
How to Stack Incentives: An Illustrative C&I Scenario
The following example is illustrative, based on typical 2026 costs and incentive rates. Actual figures depend on location, tariff, equipment sourcing, and whether the project qualifies for AEPC support.
Scenario — 200 kW Commercial Rooftop, Kathmandu Valley
| Item | Amount |
|---|---|
| Gross installed cost | NPR 18,000,000 |
| Customs/VAT relief on imported equipment | −NPR 1,800,000 |
| AEPC 50% interest subsidy over 5 years | −NPR 1,500,000 |
| Net effective cost | NPR 14,700,000 |
| Annual bill savings at high self-consumption | NPR 3,200,000 |
| Payback | 4.6 years |
Without the interest subsidy and tax relief, the same system could pay back in seven to eight years. The biggest lever is not the export credit. It is using as much solar generation on site as possible.
Common Mistakes and Misconceptions
Even experienced installers lose money in Nepal by misunderstanding how incentives interact.
Treating Nepal’s Export Credit as Net Metering
Many sellers advertise “net metering” at the retail rate. In practice, NEA pays NPR 5.94/kWh for exports, which is lower than most retail tariffs. Customers should be shown self-consumption savings first and export credits second.
Oversizing for Export
Because the export rate is low, every exported kilowatt-hour is less valuable than a kilowatt-hour consumed on site. Systems should be sized to match load, not roof area.
Ignoring the 500 kW Cap
Factories that install more than 500 kW expecting net billing can be forced into a PPA route or lose compensation for surplus. The system size must be chosen before procurement.
Missing Certification Requirements
To qualify for VAT relief and grid connection, panels and inverters generally need to meet Nepal Photovoltaic Quality Assurance (NEPQA) standards certified by the Renewable Energy Test Station (RETS), according to Urjakhabar (2025). Importing uncertified cheap hardware can disqualify the project.
Underestimating Grid Constraints
Grid capacity and voltage stability are real issues in some industrial areas, especially in the western Terai. A feasibility study that ignores evacuation can turn a good project into a stranded asset.
Conclusion
Nepal’s solar incentive framework in 2026 is a stack built from net billing export credits, AEPC interest subsidies, concessional customs duty, VAT exemptions, and a new budget push for solar, storage, and green hydrogen. None of these mechanisms is as simple as a single upfront rebate, but combined they make solar an attractive option for C&I customers with daytime loads.
For solar professionals, the competitive edge is no longer just installation price. It is the ability to model the right system size, prove self-consumption value, and stack AEPC and customs benefits correctly. Tools like Clara AI and SurgePV’s generation and financial tool can automate that workflow for Nepali projects.
Three actions to take now:
- Size for self-consumption — exported energy is worth only NPR 5.94/kWh, while avoided retail purchases are worth more.
- Secure AEPC and customs documentation before procurement — the 50% interest subsidy and 1% customs duty only apply with the right approvals.
- Stay under the 500 kW net billing cap unless a PPA route is planned — larger rooftop systems need a different commercial structure.

Frequently Asked Questions
What solar incentives are available in Nepal in 2026?
Nepal’s 2026 solar incentives include net billing for exported rooftop solar at NPR 5.94/kWh, a 50% interest subsidy for commercial and industrial rooftop systems through AEPC’s DKTI programme, concessional 1% customs duty on solar and wind project equipment, VAT exemptions on qualifying imports, and performance-based support through the Sustainable Energy Challenge Fund.
Does Nepal offer a direct subsidy for residential rooftop solar?
No. There is no nationwide direct capital subsidy for residential rooftop solar in Nepal. Households benefit mainly from lower electricity bills and, in some cases, net billing export credits. Most grant support is directed at off-grid rural systems, solar irrigation, and commercial and industrial rooftop programmes.
What is the net metering tariff in Nepal?
Since the rules were reinstated in February 2023, NEA compensates exported rooftop solar at NPR 5.94 per kWh. This is effectively net billing, because the credit rate is lower than the retail tariff most consumers pay for grid imports.
What is the maximum rooftop solar capacity allowed under Nepal’s net metering rules?
The current framework allows net metering arrangements for rooftop systems up to 500 kW. Systems above that size must typically enter a power purchase agreement route rather than the simplified rooftop net metering arrangement.
What tax exemptions exist for solar equipment in Nepal?
Nepal applies a concessional 1% customs duty on construction equipment, machinery, tools, batteries, steel sheets, and related raw materials used for solar and wind projects. VAT exemptions are also available on qualifying solar generating equipment and project imports when recommended by AEPC or the Department of Electricity Development.
Can commercial and industrial projects access solar incentives in Nepal?
Yes. C&I rooftop projects can receive a 50% interest subsidy for five years under AEPC’s DKTI programme, or interest or generation-based support through the Nepal Renewable Energy Programme. They also benefit from concessional customs duty and VAT treatment on imported equipment.
What is Nepal’s solar target for 2026?
The FY 2083/84 (2026-27) budget targets 370 MW of new solar capacity and an overall installed electricity capacity of 5,535 MW. The budget also funds a 100 MW battery storage project in Kathmandu and a 2.5 MW green hydrogen pilot in Hetauda.
Is utility-scale solar attractive in Nepal?
Utility-scale solar is growing but faces challenges. NEA tendered roughly 800-960 MW of grid-connected solar with PPA ceilings near NPR 5.94/kWh, but developers have raised concerns that this rate is too low given financing costs, land constraints, and grid evacuation issues.
What is the typical payback period for a commercial solar system in Nepal?
Well-designed commercial rooftop systems in Nepal often pay back in five to seven years, driven by high retail tariffs, daytime consumption offset, and available interest subsidies. Payback is faster when most generation is consumed on site rather than exported at the lower NPR 5.94/kWh rate.
What is the most common mistake when sizing a solar system in Nepal?
The most common mistake is oversizing for export. Because NEA pays only NPR 5.94/kWh for exports while retail import tariffs are higher, every exported kilowatt-hour is worth less than a kilowatt-hour consumed on site. Systems should be sized to maximise self-consumption and stay within the 500 kW net metering cap.
