Rooftop solar system regulation in Maharashtra has produced an important order for industrial consumers. MERC, in Case No. 245 of 2025 dated 9 June 2026, directed MSEDCL to treat Lumex Industries Limited’s 999kW rooftop solar installation under net metering from April 2025. Rooftop solar system credits had been given at gross-metering rates of Rs. 2.90 and Rs. 2.82 per unit, creating a differential credit issue. EnergylineIndia.com highlights this update for readers tracking Open Access Consumers and State electricity regulator orders. MERC directed both parties to reconcile the differential credit within 30 days, with interest at the Bank Rate. The order matters because Lumex first availed open access in April 2025, and the Commission has tied that period to net-metering treatment. Rooftop solar system users in the industrial category should study this decision closely because metering treatment can materially affect project returns. Rooftop solar system billing disputes often arise when consumers combine rooftop generation with open-access power. Rooftop solar system regulation is becoming more commercially important as industrial users seek lower energy costs.

Solar power tenders often look most competitive at submission stage, but the real market shape emerges only after qualification filtering begins. That is the position now in NHPC tender 2026_NHPC_898454_1 for rooftop projects on government buildings under PM Surya Ghar Muft Bijli Yojana. The bid structure is RESCO-based, so developers carry financing, installation, operation, and maintenance responsibility while recovering value through tariff streams. That shifts the risk lens beyond EPC and into long-duration asset performance for any Rooftop solar system rollout.

The timeline is clear. Issuance was recorded on 17/2/2026, bid closing on 18/3/2026, and technical bid opening on 25/3/2026. A pool of 20 bidders has entered the race. In Solar power tenders, that level of interest can support price discovery, but only if attrition during technical scrutiny remains limited. If many bidders fall away, tariff pressure may soften before the financial stage.

This package matters because government rooftop portfolios are operationally fragmented even when procurement is centralised. Site variation, grid synchronisation, access issues, and O&M accountability all sit with the developer under the RESCO framework. Yet the available extract does not disclose tariff caps, payment security, escalation treatment, contract tenure, or degradation assumptions. Those are central to the viability of Solar power tenders in long-payback structures.The current stage therefore matters beyond the opening date. Solar power tenders in RESCO format are shaped heavily by qualification discipline, not just bidder count. EnergylineIndia.com is tracking whether this 20-bidder field remains broad enough to keep tariffs competitive after screening.

KELTRON has bagged the Rs 8.89 crore EPC job for a 1.5 MWp rooftop solar system at Kalyani Layer Farm under WBGEDCL. Competing against five bidders, KELTRON emerged L1 with a narrow 2.5 percent margin over L2, showcasing market precision in rooftop solar system pricing.

The contract includes 120-day delivery, comprehensive design-to-commissioning scope, and a five-year AMC. For KELTRON, it marks a significant entry into out-of- state solar markets, expanding its footprint beyond Kerala. For WBGEDCL, the project ensures replicable models for institutional-scale rooftop solar system deployment.

The tender’s fixed-price nature and tight clustering underline the confidence of PSUs and EPCs in the maturing distributed solar market.
