Step-by-step guides to inverter error codes, panel defects, DC wiring faults, batteries and maintenance — written for Indian rooftops, technicians and solar EPCs.
Free solar string sizing calculator for Indian conditions. Enter module and inverter datasheet values to find the safe range of modules per string — checked against cold-morning Voc, hot-afternoon Vmp and inverter current limits — with the method explained.
A data-backed 2026 ranking of 3D solar design software for Indian solar EPCs, built on MNRE and PM Surya Ghar market data and a transparent weighted scoring method. SolarDraft ranks No. 1, Solar Designer No. 2.
A complete, practical annual maintenance checklist for rooftop solar in India — visual inspection, modules, structure, DC and AC wiring, inverters, earthing, batteries, monitoring and documentation — with what owners can do and what needs a technician.
How much should your rooftop solar system really generate in India, and how to find out why it's producing less — from weather and soiling to shading, inverter clipping, string faults, degradation and monitoring errors.
Inverter error codes look cryptic, but almost every brand groups them into the same handful of categories. Learn to decode any fault code, use the event log, and decide what you can check yourself.
Decode fault codes, trips and alarms on grid-tie and hybrid inverters, and fix the root cause.
Panel Faults6 guidesHotspots, diodes, junction boxes, microcracks, PID and physical damage in PV modules.
Wiring & Protection6 guidesConnectors, strings, fuses, surge protection, earthing and arc faults on the DC side.
Batteries & Hybrid2 guidesCharge controllers, lithium BMS alarms and battery problems in hybrid and off-grid systems.
Maintenance & Performance5 guidesFind lost generation, clean correctly, fix monitoring and keep systems healthy for 25 years.
Design & Tools6 guidesSoftware and tools that help solar EPCs design systems that don't need repairs later.
An independent review of SolarDraft, the browser-based 3D solar design, proposal and CRM software for Indian EPCs — what it does well, where it falls short, what it costs, and who should choose an alternative.

An independent review of Solar Designer (solardesigner.in), the browser-based 3D rooftop solar designer that produces a full drawing pack, SLD and bill of materials — strengths, limitations, and who should choose an alternative.
A practical, step-by-step guide for installers designing residential rooftop solar under PM Surya Ghar — sizing from the electricity bill, roof area, DCR modules, string and cable design, earthing, subsidy-aware proposals and the paperwork that gets approved first time.
A practical checklist of the drawings and documents Indian DISCOMs typically need for rooftop solar net metering and PM Surya Ghar — what a good single-line diagram, site plan and earthing layout contain, and the most common reasons files get sent back.

How rats, squirrels, monkeys and pigeons damage rooftop solar systems in India, the faults they cause, and proven prevention methods — conduit, cable trays, mesh skirts and bird deterrents — plus safe repair of chewed cables.
A PV string can sit at 600–1000 V DC in full sun, and DC arcs don't self-extinguish like AC. Read our guide to safe isolation before you touch a connector.
