Market Trends and Insights

Mandatory rooftop-solar regulation for new grid connections

New industrial and commercial electricity connections can create solar demand at the point when an establishment secures its power supply. A Power Division circular reported on December 21, 2025, required new industrial and commercial connections of at least 10 kW to install net-metered rooftop solar at a minimum 20% of approved load, subject to sufficient roof space.^[1] The circular took effect immediately, with systems required to follow the Net Metering Guideline 2025. Linking solar installation to the connection application creates a specific investment trigger for eligible customers. Suppliers can address that trigger by aligning rooftop assessment and system sizing with the customer's approved load. The roof-space condition makes site qualification decisive in converting the requirement into an installable project.

Rapid decline in PV module prices & BOS capex

Lower module prices can reduce the capital committed to panels before a project begins generating electricity. The IEA Photovoltaic Power Systems Programme reported that module prices in China in 2025 were more than 60% below 2023 levels.^[2] Electrical work, support structures and integration must be funded before the system can enter service. The commercial opportunity therefore extends beyond obtaining cheaper panels to fitting the complete installation within the customer's investment envelope.

Export-buyer decarbonization pressure on RMG industry

Buyer decarbonization pressure can support solar demand without being the dominant reason an apparel exporter adopts renewable energy. The International Growth Centre's April 19-May 6, 2025, survey found that 12% of renewable-energy adopters among Bangladesh apparel exporters cited direct buyer pressure as their main adoption reason. BESTSELLER's 2025 due-diligence report said its parent, HEARTLAND, financed purchases and installation of solar systems on supplier factory roofs in Bangladesh through an initiative with SOLShare. This connects a buyer's decarbonization objective with financial support for the generating equipment. Because most adopters named a different main reason, a developer selling to apparel exporters has to establish the factory's own energy case, with buyer-funded finance such as the HEARTLAND initiative complementing that case.

Rising LNG/oil import bills inflating grid tariffs

Rising grid charges increase the value of solar electricity that a commercial customer can consume on site. The Bangladesh Energy Regulatory Commission (BERC) raised weighted-average retail and wholesale electricity tariffs effective with June 2026 billing. The regulator said the adjustment was necessary to reduce the government's power-sector subsidy requirement. Bangladesh officials said the Middle East war that began on February 28, 2026, disrupted fuel supply chains and sharply increased import costs for LNG, coal and furnace oil used in electricity generation. For a commercial rooftop project, the relevant gain is the value of purchased electricity displaced by usable generation. Project appraisal can capture that enacted increase without depending on another tariff adjustment to make the investment worthwhile.

Land acquisition bottlenecks for utility-scale parks

Securing a solar site close to a substation creates a combined land-access and connection problem for utility developers. In its 2025 review, Transparency International Bangladesh (TIB) found that independent power producers developing ground-based solar were frequently required to secure land themselves, while substation proximity requirements raised local land prices and disrupted timely implementation. Electrically convenient locations can therefore become more expensive precisely because they help meet a project's connection requirements. On April 7, 2026, the Power Division issued an immediately effective guideline facilitating renewable-energy development on unused or underused public land through public-private partnerships. Suitable land consequently becomes an independent power producer's development expense and scheduling dependency, with site access required before construction.

Grid evacuation lags prompting curtailment risk

Solar project delivery depends on aligning the generating plant with its evacuation infrastructure. In September 2026, Rural Power Company Limited's 100 MW Madarganj project was delayed, affecting its transmission-line component. The 47-kilometer line to Ghatail was close to completion, while remaining construction and commissioning were required before generation. The Centre for Policy Dialogue (CPD) reported for July to September 2025 that Korotoa Solar Limited's 30 MW Tetulia plant in Panchagarh had been stalled at transmission-line development since April 2024, after nearly 3 years in land development. Power Grid Bangladesh PLC reported 3.10% physical progress on October 1, 2026, on a transmission project for planned renewable plants in southern Chattogram, with an estimated June 30, 2030, end date. Until plant and line are both ready, developers carry committed capital without generation revenue.

Bangladesh Solar Energy Market Segment Analysis

Solar photovoltaic (PV) accounted for a 100% share of the Bangladesh solar energy market size in 2026 and is forecast to grow at a 12.68% CAGR over 2027-2032, making it both the largest and the fastest-growing segment. The International Renewable Energy Agency reported 1,146 MW of installed PV capacity in Bangladesh in 2025. With installed capacity entirely PV, additional engineering, procurement and construction (EPC) work would expand an established technology base, making project execution central to capacity growth.

PV's modular structure makes the size of a customer project a commercial design choice within the same solar technology. The US Department of Energy explains that PV arrays can be assembled to meet small or large electric-power needs. For a supplier serving Bangladesh, that supports a common technology platform across separately sized installations, while the buyer's electricity requirement defines the generating package. In June 2026, the 2.49 MWp plant at Padma Bridge Service Area 2 supplied daytime electricity under net metering and exported surplus to offset grid use at night or during low solar generation. Modular sizing can thus match a site's generation and export role without requiring solar to supply every hour of consumption.

On-grid systems made up the largest segment with 80.77% of installed solar capacity in 2026 and are forecast to grow at a 14.82% CAGR over 2027-2032 as the fastest-growing segment. By early 2026, more than 4,490 net-metered rooftop systems totaling around 214 MW were connected to Bangladesh's 6 power distribution networks. That installed base provides a channel through which additional customer-site systems can be connected in separate projects. Handling applications across the 6 networks becomes part of the developer's service because each installation needs its distribution utility's inspection and approval.

Net-metering economics make customer consumption and export-credit terms central to the connected-system proposition. Under the 2025 guideline, 90% of net exported electricity is credited and carried between billing periods, with settlement-period payment at bulk rates restricted to consumers with Annex 4 agreements. Off-grid systems serve a different buyer, and Infrastructure Development Company Limited (IDCOL) supports solar mini-grids for households and small commercial users in remote areas where grid expansion is unlikely in the near future. Its 2025 annual report described 26 mini-grids providing grid-like electricity to more than 16,000 beneficiaries. The commercial difference is between settling electricity against a utility account and delivering access to a remote community, requiring offers built around those distinct services.

Utility-scale installations represented a 52.62% Bangladesh solar energy market share in 2026, making them the largest segment. IDCOL reported financing 132 MW of utility-scale solar during FY2025.^[3] Separately, in January 2026, the Bangladesh Power Development Board (BPDB) signed 20-year power purchase agreements for 7 grid-connected solar projects totaling 523 MW, with the supply term starting at commercial operation. IDCOL's terms for large grid-tied renewable-energy independent power producers provide commercial financing and possible USD loan eligibility. Because the contracted supply term starts at commercial operation, finishing a plant activates both its capacity contribution and the agreement's long-term commercial life.

Residential solar is the fastest-growing segment, with a 32.6% CAGR forecast for 2027-2032. At an August 2026 CPD briefing, Hasan Mehedi, CEO of CLEAN, reported that Bangladesh's residential sector consumed 51.94 TWh of electricity in 2024-25. That household demand provides a potential load base for property-level projects, with commercial conversion depending on installations matched to individual homes. On October 18, 2026, IDCOL said it would extend rooftop-solar financing through demand aggregators at a maximum 6% interest rate to households, businesses, industries and small enterprises. The announced aggregator channel would let installers approach dispersed households through financed purchases, a different sales route from utility-scale plant contracts.

The Bangladesh Standards and Testing Institution (BSTI) opened a Dhaka laboratory on November 5, 2025, to measure solar module efficiency and test panels up to 2,700 mm × 1,600 mm. Inverters convert panel-generated direct current into grid-compatible alternating current, with central units serving arrays, string units serving panel groups and microinverters serving individual panels. The Electricity Generation Company of Bangladesh Limited (EGCB) reported 24 Sungrow inverters rated 3,125 kVA/3,427 kVA at 50/45°C at its 75 MW Sonagazi plant in FY 2024-25. Mounting and tracking systems differ in whether arrays remain fixed or move to follow the sun, as described in National Renewable Energy Laboratory technical guidance. Module buyers can compare measured efficiency, while inverter buyers can assess ratings at specified temperatures, giving suppliers distinct performance criteria to demonstrate.

Balance-of-system and electricals provide a plant's connection path to the delivery network. EGCB's Sonagazi system included 12 medium-voltage and 2 high-voltage transformers and a 13.33-kilometer, 230 kV line to Power Grid Bangladesh PLC's Mirsarai substation in FY 2024-25. Energy storage and hybrid integration were illustrated by GoodWe, distributor ACI Renewable Energy and EPC partner Greefinity commissioning a fully off-grid solar-plus-storage system for a Jessore Sadar resort-cum-villa on June 19, 2026. The installation used solar by day and batteries at night in an area where grid availability was often limited to a few hours daily. Serving nighttime loads consequently calls for an integration brief that differs from one centered on delivering electricity through a grid connection.

Geography Analysis

Dhaka Division Solar Energy Market

Dhaka Division accounted for a 37.6% share of the Bangladesh solar energy market size in 2026. At its August 2, 2026, briefing, CPD identified the division as the leading concentration of net-metered rooftop installations within its national review of 4,551 systems. That installation pattern creates a potential commercial channel for suppliers that can deliver repeated customer-site projects, with coordination occurring at the property and distribution-connection level.

In Gazipur, Banglalink's data-center installation illustrates how existing facility space can host a defined solar investment. The operator installed an 80 kW system on 9,000 square feet of unused rooftop space in August 2025. The system was expected to generate about 0.13 GWh annually, cut carbon emissions by 60 metric tons annually and save about USD 12,600 in annual energy costs. The commercial advantage is the conversion of unused roof space into a generating area, allowing a telecommunications-site investment to be framed around expected energy savings without developing a separate solar-park site.

Chattogram's hospitality example highlights a customer whose solar project includes both a building installation and a utility-facing export function. Galleria inaugurated an 80 kW net-metered rooftop system in September 2025. The installation used Sofar Solar inverters and fed electricity back to the national grid through net metering. The system links a property's generating equipment to utility-account settlement, making export integration part of the hospitality installation. Hospitality-focused suppliers can pursue commercial sites through complete generation and export packages organized around a specific property's solar installation.

Regulatory Framework and Outlook

The table compares selected jurisdictions through Bangladesh's national net-metering framework and its implementation by the applicant's distribution utility, from the perspective of a rooftop-system owner seeking interconnection. The Sustainable and Renewable Energy Development Authority (SREDA) issued the guideline, while the Power Division's online portal routes applicants to their distribution utility. Eligibility depends on utility-customer status, no arrears, legal site rights, self-consumption before export and compliance with interconnection rules. Installation permission follows the utility's inspection and approval process.

For the national framework, Medium reflects a defined application route combined with substantive eligibility and interconnection conditions. Utility-level implementation keeps the same Medium reading because the applicant's distribution utility inspects and approves the installation under the national guideline. The connection circular reported in December 2025, the September 2026 battery-based rooftop surplus-power incentive and the July 2026 cabinet-approved draft strategy add installation, payment and target provisions. For this owner's interconnection decision, the utility application route under the 2025 guideline continues, supporting No change despite those separate commercial measures.

Value Chain Stages

The value chain compares how module production, project finance, construction and system upgrades capture earnings around solar delivery. Radiant Alliance, an East Coast Group affiliate, previously produced for domestic solar home systems and sent its first consignment to US-based CleanGrid on June 19, 2025, under a 4-year export agreement. IDCOL provides long-term finance, debt and equity arrangements and technical assistance through a renewable-energy platform that includes solar. Solaric's Singapore parent and Bangladesh subsidiary develop industrial rooftop projects under capital-expenditure and operating-expenditure models.

In June 2025, local module manufacturers reported that low-quality imports were undermining domestic production. This gives suppliers a basis for competing on verifiable module quality alongside equipment price. Under Solaric's OpEx model, the roof owner pays in annual installments while the provider maintains the system for 20 years, extending value capture into long-term service. At the finance stage, IDCOL's rooftop soft loans provide a financing-income channel, while its advisory, technical and performance-monitoring support ties that role to project performance.

Key Opportunities for Market Participants

The opportunities compare rooftop investments activated by surplus-export incentives for battery-based systems, public-building requirements and factory financing. The first two routes have installation deadlines, making timely design and commissioning central to an eligible customer decision. The factory route makes financing terms part of the solar supplier offer, because technically viable sites are more numerous than the investment-ready group.

For factory rooftops, financing terms help define the addressable buyer group. CPD's August 2026 model of 3,320 ready-made garment (RMG) factories placed no factory in the investment-ready tier in the commercial 10.5% financing scenario, with separate tiers for projects needing support or intervention. Concessional or blended finance therefore determines whether the modeled customer pool includes factories able to proceed without special conditions.
