Pursuing rooftop solar is economically compelling for industries and commercial
The rapid installation of 2,000 megawatts (MW) of rooftop solar systems in Bangladesh could reduce 15 million tonnes of CO2 through 2023-30 and contribute to achieving the country''s Nationally Determined Contributions (NDCs).
Currently, the payback period for a 1MW rooftop solar is over six years. Another round of electricity price hikes could reduce the payback period to around five years.
Bangladesh Bank''s green refinance scheme has interest rates from 5 to 6%. The Infrastructure Development Company Ltd. (IDCOL) offers loan for rooftop solar projects at 6%. These low-cost financing facilities could spark a rooftop solar revolution.
To help boost rooftop solar adoption, the government must ensure the quality of solar-related accessories and waive import duty on inverters. Stakeholders also need updated information and a simpler loan disbursement process.
Bangladesh has set a target of unconditionally reducing 26.31 million tonnes of CO2 equivalent from the energy sector alone by 2030 in its Nationally Determined Contributions (NDC).
To achieve its goal, Bangladesh cannot afford to ignore the vital role rooftop solar can play in decarbonising the energy sector. Rapid implementation of 2,000 megawatts (MW) rooftop solar systems without battery storage could roughly reduce 15 million tonnes of CO2 from 2023 to 2030.
Fossil fuels still dominate Bangladesh''s electricity system. The country''s on-grid renewable energy capacity is merely 584MW out of the installed capacity of 22,607MW (excluding off-grid and captive systems). Of the renewable energy capacity, rooftop solar installations are at a paltry 90MW compared to the ballpark potential of 5,000MW from only rooftops of existing industries.
Rapid implementation of 2,000 megawatts (MW) rooftop solar systems without battery storage could roughly reduce 15 million tonnes of CO2 from 2023 to 2030.
Bangladesh would be better off exploiting rooftop solar at scale as this is one of the cheapest sources of green energy.
About a decade ago, high prices of solar panels held back the country''s large-scale adoption of solar energy. However, during 2010-19, solar panel costs fell sharply to US$0.38 per watt from US$2 per watt in the international market. This made solar power affordable and competitive with most fossil fuels.
Reportedly, electricity prices for consumers are likely to increase following the latest hike at the wholesale level. As such, industries and commercial building owners can fix energy bills using rooftop solar systems when the sun is available.
Assuming an average availability of sunshine for four hours a day throughout the year and 15 days of shutdowns for various reasons, a 1MW rooftop system can generate approximately 1,400MWh per annum. The payback period for a 1MW rooftop system for an industrial entity would be just over six years at the current tariff of Bangladesh Taka (Tk) 8.45 per kilowatt-hour (kWh). An electricity price hike, which is highly likely, could reduce the payback period to around five years.
With more than 4,000 industries, the apparel sector, contributing 9.25% to the gross domestic product (GDP) and 82% of the total export earnings during the fiscal year (FY) 2022, could deploy a significant capacity of rooftop solar systems to cut emissions. This is because the sector faces international competition and needs to reduce its carbon footprint as part of the buyers'' compliance and the global fight against climate change. Other industries and commercial buildings could follow suit from a purely commercial angle.

Recent changes in Bangladesh Bank''s green refinance scheme increase rooftop solar projects'' attractiveness. Now, industries/commercial building owners can avail of debt finance at 5 to 6%, subject to loan tenor.
Similarly, the Infrastructure Development Company Ltd. (IDCOL) offers loans to rooftop solar projects at a 6% interest rate. Being an accredited entity of the Green Climate Fund (GCF), IDCOL could also develop an extensive programme for industrial rooftop solar systems, following the model it has adopted in its GCF project for enhancing energy efficiency in Bangladesh''s garment sector. Moreover, with the falling price of solar energy and reduced payback periods, investors would encounter fewer risks than they had at a borrowing rate of 9%.
Furthermore, the net metering guidelines of Bangladesh allow industries and commercial buildings to install rooftop solar systems and connect to the national grid through a bidirectional meter. As the levelised cost of electricity from rooftop solar systems is roughly Tk5.5/kWh, they will save significantly by reducing grid electricity consumption that currently costs industries Tk8.45/kWh and commercial buildings Tk9.02/kWh.
Despite huge potential, to maximise the benefits of rooftop solar facilities in the country, fixing a couple of problems is imperative. For instance, in the absence of locally manufactured high-quality inverters, people rely on imported inverters. Currently, the import duty on inverters is 37%, which raises project costs and demotivates investors.
There is also concern over the quality of solar equipment. While Bangladesh needs to import solar panels and inverters, sufficient testing facilities are unavailable to check and ensure quality. This calls for establishing accredited testing labs with adequate capacity to provide quality checks of solar panels and related accessories. In addition, to ward off the market penetration of sub-standard solar accessories, the Bangladesh Standards and Testing Institute (BSTI) may consistently monitor the market.
The green refinance scheme, launched by the Bangladesh Bank in 2009, has undergone a series of revisions over the years. Therefore, many stakeholders might be oblivious to the present terms and conditions of the scheme. The central bank can carry out an awareness-raising campaign on the recent changes in green refinancing to address the information asymmetry and/or attract industrial and commercial entities to invest in cost-competitive rooftop solar projects.
The Sustainable and Renewable Energy Development Agency (SREDA), the government-mandated agency to promote clean energy, could organise sessions with industries, commercial entities and their associations. In these sessions, the SREDA can create awareness and enlighten stakeholders about how its solar helpdesk could support them with technical, policy and other information.
Stakeholders also have the impression that financing mechanisms, both under the Bangladesh Bank and IDCOL''s facility, are complex and time-consuming. SREDA might work with Bangladesh Bank and IDCOL to address the concerns of stakeholders to help spur financing in rooftop solar projects.
With the rising cost of electricity, the low-cost green refinancing scheme and IDCOL''s facility have increased the attractiveness of rooftop solar systems. While these are important steps to increase the adoption of rooftop solar systems, stakeholders also need updated information and a simpler loan disbursement process. Moreover, to usher in a rooftop solar revolution to help achieve its NDC targets, the government must ensure the quality of panels and waive import duty on inverters.

The need for a new energy order is essential in light of the heavy financial losses of the Bangladesh Power Development Board (BPDB) in the fiscal year (FY) 2022-23.
Bangladesh''s new energy order must address the challenges of import dependence that cause serious upheavals, including a rising subsidy burden.
Rooftop solar has the potential to play a central role alongside other clean technologies, especially in mitigating expensive power generation and purchase during the daytime, reducing the BPDB''s revenue shortfall.
Bangladesh''s persisting energy sector challenges of more than one and a half years raise policy concerns and the need to spearhead a new energy order. The new order must focus on increasing renewable energy contribution and reducing demand through energy efficiency to make the country''s energy model more resilient and sustainable. The need for a new energy order is essential in light of the heavy financial losses of the Bangladesh Power Development Board (BPDB) in the fiscal year (FY) 2022-23.
Against such a backdrop, rooftop solar has the potential to play a central role alongside other clean technologies, especially in mitigating expensive power generation and purchase during the daytime, reducing the BPDB''s revenue shortfall. Pursuing rooftop solar is economically compelling for industries and commercial buildings. The new regulatory directive also requires new buildings to install rooftop solar systems to secure grid connections.
As of December 2023, the combined rooftop solar capacity installed under net-metered and non-net-metered systems reached only 162.73 megawatts (MW). This paltry rooftop solar capacity heightens the importance of fixing prevailing problems to accelerate the sector''s expansion.
Rooftop solar can help reduce the BPDB''s revenue shortfalls
Many of the BPDB''s problems emanate from its exorbitantly expensive power purchase from some private plants, which operate at a very low capacity. The obligation for capacity payments to such plants raises the overall costs, causing the BPDB to purchase power at a price 7 to 8 times higher than its bulk selling price. High prices of fossil fuels in the international market also affected the power sector in FY2022-23. Eventually, the financial loss reached Bangladeshi Taka (Tk) 117.65 billion (US$1.07 billion) in FY2022-23, despite a whopping subsidy of TK395.35 billion (US$3.6 billion) allocated by the government.
However, a significant rooftop solar capacity could allow the government to phase out some expensive power plants. A recent study by the Institute for Energy Economics and Financial Analysis (IEEFA) substantiated that a combined rooftop solar capacity of 2,000MW, if installed by industries and building owners, could help BPDB minimise power generation and purchase costs between Tk52.3 billion (US$476 million) and Tk110.32 billion (US$1 billion) a year. This is how BPDB can reduce its soaring revenue shortfall.
Upscaling rooftop solar requires fixing current problems
While rooftop solar installations surged in 2023, the present installed capacity of less than 200MW seems grossly inadequate. Interest among building owners remains scattershot. This is despite the tariffs that make rooftop solar lucrative for industries and commercial buildings. Among other things, lack of awareness of the benefits of rooftop solar, high import duties on accessories, perceived risks of financiers, capacity gap of sector stakeholders and lack of business models for utilities hinder the smooth uptake of rooftop solar in the country.
