Delhi solar installations face a unique enemy: intense winter smog, sticky PM2.5 soot, and vehicular exhaust that bonds to panel glass and cuts generation by up to 25% during peak winter months. SolarTrust's specialized AMC bridges the gap between installed capacity and actual generation — keeping your PM Surya Ghar or commercial rooftop performing under India's most polluted urban sky.
Generic maintenance schedules designed for milder environments simply don't work here.
From November to February, temperature inversions trap PM2.5 and unburned hydrocarbons close to the ground. This soot bonds with morning dew to form a sticky, greasy film that rain and dry-wiping cannot remove. It severely blocks UV and visible light, dropping winter generation by up to 25%.
Up to 25% winter generation lossDelhi's dense colonies — Janakpuri, Dwarka, Rohini — mean panels constantly fight water tanks, parapet walls, and overhanging trees for sunlight. One shaded corner drags down an entire string. Our AMC includes shading analysis and bypass diode verification at every visit.
Entire string degraded by one shadowRodent-chewed MC4 connectors and DC cabling are the leading cause of rooftop solar fires in Delhi. Urban rodents nest inside conduits and under panels. Our AMC includes systematic connector and cabling inspection at every visit — before arcing starts.
Leading cause of rooftop solar firesDelhi's mixed residential-industrial grid experiences frequent voltage swings that disconnect inverters and cause lost generation. We review and tune inverter grid-tolerance settings and verify surge protection devices are functional at every visit.
Nuisance tripping eroding daily yieldWinter Generation Loss Without AMC
Delhi's smog season silently erodes solar output every winter. Without professional AMC, this loss compounds year-over-year and extends your payback period by 6–18 months.
From heavy industrial belts to dense residential colonies, our Delhi team covers every solar micro-environment in the NCT.
Heavy industrial soot, fly ash, and chemical particulate require surfactant-based deionized water cleaning. Thermal inspections quarterly to catch hotspots.
Large-format manufacturing clusters where oily chemical particulate bonds to panels, requiring industrial-grade specialist cleaning protocols.
High-density residential zones where bird droppings, water-tank shadows, and partial shading are the primary performance culprits.
Green-belt zones with tree-shading risk and pigeon nesting under panels — requiring annual structural inspection alongside cleaning visits.
High-value commercial rooftops where mandatory safety protocols (harnesses, edge protection) and non-disruptive scheduling are essential.
Dense residential colonies with parapet-wall shading issues and rooftop access constraints requiring specialist maintenance logistics.
Every service is calibrated for local operating conditions — not a generic package copied from a milder climate.
Scheduled cleaning with deionised water, panel inspection, electrical safety checks, and torque testing. Every visit is GPS-tracked and photo-documented in our app.

Delhi residential, commercial & industrial clients
"Our Rohini residential colony's 15 kW system was generating 22% below expectation. SolarTrust found both a shading issue and pigeon nesting under two panels in the first visit."
"The winter smog season used to completely kill our Okhla plant's yield. SolarTrust's bi-weekly cleaning in November–February recovered nearly 18% of generation we were simply losing."
Our certified engineer will visit your site, conduct a 30-point inspection covering panels, inverters, cabling, shading, and generation data, and deliver a detailed report with prioritised, costed recommendations.
