Solar panel installation across Telangana and Andhra Pradesh

It depends which stage you mean. The physical work — mounting the panels, wiring, connecting the inverter — is typically finished within a few days for a domestic system. What actually determines the overall timeline is the DISCOM feasibility approval, inspection and net-metering application, which run on the DISCOM’s schedule, not ours. See the stage-by-stage process above for what happens at each point.

You need to be available for the survey and for the handover, and someone must be able to give access on working days. You do not need to supervise the work itself.

A properly executed installation should not. Mounting method depends on roof type: ballasted structures on flat concrete roofs avoid penetration entirely, while pitched roofs use sealed fixings. Roof condition is assessed at survey precisely so this is decided before work starts, not during it.

Origian Power works across Telangana and Andhra Pradesh, with completed installations in and around Hyderabad, Anantapur and Kalyandurg. Call us with your location and we will confirm whether you are in our current service area.

We do. Feasibility application, inspection coordination and the net-metering application are all part of the installation, not a separate service you arrange yourself. Origian Power is not a registered PM Surya Ghar vendor, so we do not file subsidy applications.

Ask who is legally accountable if the system underperforms or a component fails — a single EPC contractor, or separate parties for supply and installation who can blame each other. Ask to see the product, performance and workmanship warranty documents, not just a verbal figure. Ask who submits and tracks the DISCOM feasibility, inspection and net-metering applications, since that is where most delays happen. And ask for real, named completed installations you can check, not just a capacity figure on a quotation.

A price with no equipment brand named, a payback claim with no assumptions shown, and pressure to sign before a site survey has happened are the three we see most. A quotation that promises your bill will go to zero is also worth questioning: fixed and demand charges are billed on the connection regardless of how much you generate, so a well-sized system reduces the bill rather than eliminating it.

Yes, with a mounting method matched to the roof rather than one structure used everywhere. Metal sheet and tin roofs generally take a clamp-fixed structure that does not penetrate the sheet. RCC and flat concrete roofs typically use a ballasted structure that avoids drilling and waterproofing damage entirely. Sloped tile roofs use sealed hook or rail fixings into the rafters underneath. Asbestos roofs need particular care because the sheet is brittle and can crack under a standard fixing — this is assessed at survey, not assumed from the roof material alone.

A structure should be designed to the wind-speed zone the site actually sits in, under IS 875 — the Indian structural code covering wind loads on buildings and structures — rather than one generic design used regardless of location. Coastal AP districts carry a materially higher design wind speed than inland Telangana, and that difference should show up in the structure’s specification. Ask any installer for the wind rating their structure is designed to, not just the panel brand.

It depends on system size, the panel and inverter brand chosen, your roof type, and whether the system includes battery storage — there is no single figure that applies to every property. What we can tell you before a survey is the PM Surya Ghar subsidy amount, which reduces the cost for eligible residential systems. The free site survey is what turns your specific roof and bill into an actual quotation, with equipment brand and price named in writing.
