GK Energy adds rooftop and storage orders beyond solar pumps

GK Energy is broadening its renewable-energy business beyond solar pumps through a 1 lakh-system rooftop-solar order, a 14,000-pump order and its first 150 megawatt (MW) by 300 megawatt-hour (MWh) battery energy storage system project. The expansion was disclosed during the October 29, 2026 earnings call, when H1 FY27 revenue reached Rs 907.8 crore.

How is GK Energy broadening its renewable-energy business?

GK Energy is adding retail rooftop solar and utility-scale battery storage to its agricultural solar-pump operations. Management described three growth engines as of September 2026: rooftop solar for residential and commercial business-to-consumer customers, solar pumps, and utility-scale energy storage.

The expansion follows continued growth in GK Energy’s existing execution business. In H1 FY27, installations increased 77.6% year on year to 43,509 systems, while commissioned capacity rose 70.8% to 193 MW. The cumulative base exceeded 1.84 lakh systems and 800 MW across India.

Rooftop solar is intended to use the operating network developed for solar pumps. Management said GK Energy’s network spans six states and more than 7,500 villages, supported by over 40 owned vehicles, more than 200 team leads and over 1,300 installation and commissioning partners.

What new orders has GK Energy disclosed?

GK Energy disclosed a 1 lakh-system institutional rooftop-solar order, an additional order for 14,000 off-grid DC Solar Photovoltaic Water Pumping Systems in Maharashtra, and a 150 MW by 300 MWh utility-scale battery energy storage system, or BESS, order. Management said the Maharashtra pump order was received in October 2026 and that the BESS award is its first storage order.

The rooftop order adds institutional volume to GK Energy’s retail rooftop activity. During the call, management said the company had installed more than 2,000 rooftop systems and had demand for about 4,000 to 5,000 further systems in the retail market.

The 150 MW by 300 MWh project takes GK Energy into utility-scale storage. Management cited a Central Electricity Authority projection, referred to by the Ministry of New and Renewable Energy, that India’s battery-storage requirement could rise from about 35 gigawatt-hours in FY27 to around 236 gigawatt-hours in FY32.

How does GK Energy’s network support the new segments?

GK Energy’s installation network supports the expansion because it delivered higher volumes even during the monsoon-affected Q2 FY27 period. Q2 installations rose 41.8% year on year to 19,391 systems, while commissioned capacity increased 33.3% to 84 MW.

Management said July-to-September is seasonally its weakest quarter because monsoon conditions slow field installation, particularly for agricultural pumps. The H1 increase of 77.6% in systems installed was therefore higher than the 41.8% Q2 increase, reflecting the effect of the seasonal installation pattern across the two quarters.

The rooftop business may also alter the customer-payment profile. Management said rooftop solar follows a cash-and-carry model, while it has typically indicated solar-pump receivables of about 120 days, with a practical range of 120 to 140 days.

What are GK Energy’s financial and order-book figures?

GK Energy reported H1 FY27 revenue from operations of Rs 907.8 crore, up 38.9% year on year and nearly 60% of full-year FY26 revenue, according to management. Earnings before interest, tax, depreciation and amortisation, or EBITDA, rose 21.6% to Rs 160.5 crore, with a 17.7% margin, while profit after tax increased 30.7% to Rs 109 crore.

In Q2 FY27, revenue increased 12.3% year on year to Rs 402.7 crore. EBITDA was Rs 74.4 crore with an 18.5% margin, while profit after tax rose 6.3% to Rs 49.4 crore and represented a 12.3% margin.

GK Energy put its order book at Rs 788 crore, comprising orders outstanding as of September 30, 2026 and orders received from October 1, 2026 onward. Management said this figure includes goods and services tax, or GST, but excludes the BESS order; it also said cumulative orders received during FY27 were Rs 1,422.29 crore.

Management separately referred to Rs 1,800 crore of revenue visibility in response to an analyst question. It distinguished that figure from the Rs 788 crore current order book by saying the visibility figure included opening orders and work already executed, including more than Rs 900 crore reflected in revenue.

What is the receivables position and management’s expansion plan?

GK Energy reported trade receivables of Rs 1,012.38 crore, or 204 days outstanding, at September 30, 2026. Management said it received Rs 377.5 crore over the subsequent 28 days, reducing outstanding receivable days to about 128 days.

Management said the collection update brought receivable days closer to the 120 to 140-day range it has discussed for the pump business. It contrasted this with rooftop solar, where it described the customer model as cash and carry rather than one involving the same receivables cycle.

For manufacturing, management said GK Energy designs products, sets specifications and controls critical sourcing, while partners across eight states manufacture to those requirements. It said this model directs capital toward execution, brand, technology and customer reach rather than owned factories.

Management said it intends to expand BESS capacity to 2 gigawatts in the medium term, without providing a timeline. It also described a 2030 ambition of 10 lakh installed systems and a US$1 billion business across decentralised renewable energy, battery storage, utility-scale engineering, procurement and construction, or EPC, and new renewable products.

Conclusion

GK Energy’s disclosed orders show a broader product mix built around its established field network. The 1 lakh-system rooftop order extends its presence in customer-facing solar, the 14,000-pump Maharashtra order supports its foundation segment, and the 150 MW by 300 MWh BESS order starts its utility-scale storage activity.

The next points to watch are execution of the Rs 788 crore order book, which excludes the BESS project, and progress on management’s stated medium-term plan to reach 2 gigawatts of storage capacity. Collection trends also remain relevant after receivable days fell from 204 on September 30, 2026 to about 128 days following Rs 377.5 crore of receipts.
