What a fair quote includes
- DCR panels from a Tier-1 maker (brand and wattage named on the quote)
- Grid-tied or hybrid inverter with monitoring
- Hot-dip galvanised mounting structure
- DC and AC cables, MC4 connectors, distribution boxes with surge protection
- Three earth pits and a lightning arrester
- Net-meter application and subsidy filing
- Installation, commissioning and handover
What moves the price up or down
- Structure height: raising panels 6–8 feet to clear tanks or create usable shade adds ₹8,000–20,000.
- Panel technology: TOPCon and bifacial panels cost a little more than Mono PERC but generate more. See panel types.
- Inverter brand and warranty length.
- Cable run from roof to meter in tall buildings.
- Batteries for hybrid systems.
Is the cheapest quote a good deal?
A system that loses 15% output to poor structure tilt, or fails an inspection because earthing was skipped, costs more over 25 years than it saved on day one. Compare quotes line by line using our installation checklist.

Frequently asked questions
What is the price of a 3 kW solar system in Telangana?
About ₹1.85–2.1 lakh for an on-grid system with Tier-1 DCR panels. After the ₹78,000 subsidy, you pay roughly ₹1.07–1.32 lakh.
Why do some installers quote much less?
Low quotes often use non-DCR panels (which lose the subsidy), painted mild-steel structures that rust, thin cables, or skip earthing and lightning protection.
How much extra does a hybrid system cost?
Roughly 35–45% more than on-grid, mostly for the batteries and hybrid inverter. A 3 kW hybrid with about 5 kWh of lithium storage is typically ₹2.6–3.1 lakh before subsidy.
