Engineering insights, solar industry news, maintenance best practices, and policy updates — written by our in-house technical team for solar professionals and informed consumers alike.
The Union Ministry of New and Renewable Energy has revised the PM Surya Ghar Muft Bijli Yojana subsidy matrix for FY 2026–27. We break down the new capacity-linked subsidy slabs, eligibility changes, revised DISCOM interconnection timelines, and what it all means for homeowners planning a rooftop installation this year.
A 5° deviation from the optimal tilt can cost you up to 8% of annual generation. Here's how to get it right for West Bengal and Sikkim latitudes.

Skipping quarterly maintenance can cost you 15–20% in annual generation losses. We share the exact 12-point checklist our field engineers use on every site visit.

Industrial consumers on ToD tariffs are sitting on untapped savings. We explain exactly how a BESS system interacts with the grid to eliminate demand charge spikes.
Rajiv Sharma
A P90 generation guarantee is only as good as the model behind it. We explain what PVsyst parameters to scrutinise and which assumptions EPC contractors routinely inflate.
Arjun Das
The panel market has evolved fast. We compare efficiency, temperature coefficients, degradation rates, and cost-per-watt across the three dominant technologies available in India today.
Priya Sen
India added 24 GW of solar in FY2025–26. We analyse the state-wise breakdown, tender pipeline, and what the accelerated build-out means for equipment supply chains and EPC margins.
Rajiv Sharma
IR thermography is one of the most cost-effective tools in a solar AMC engineer's kit. We explain how hotspot analysis works, what patterns indicate cell-level faults, and when to replace vs. repair.
Arjun Das
With several states shifting from net to gross metering policies, we model the financial impact on a 50 kW commercial rooftop system across three different load profiles and tariff structures.
