Chhattisgarh is one of India’s most power-intensive states, with a large industrial base in steel, cement, and aluminium that drives significant electricity demand. The Chhattisgarh State Power Distribution Company (CSPDCL) serves approximately 5.5 million consumers across the state, and net metering for rooftop solar is governed by CSERC regulations with CSPDCL as the implementing agency. The state receives strong solar irradiance of 1,500–1,700 kWh/m² annually, making it an attractive market for both residential and commercial solar.
This guide covers Chhattisgarh’s solar policy, net metering process, subsidies, and compliance requirements. For the broader Indian regulatory framework, see the India solar compliance hub.
Empanelled Vendor Requirement for Residential Subsidy
To claim the PM-Surya Ghar central subsidy and the Chhattisgarh state subsidy, residential customers must use a vendor empanelled with CSPDCL. Installing through a non-empanelled vendor voids subsidy eligibility. The empanelled vendor list is published on cspdcl.co.in and updated quarterly. Always verify vendor empanelment status before signing a contract.

Application Process
Step-by-Step Guide
Check CSPDCL service area and eligibility
Verify your property is within CSPDCL’s jurisdiction. Most of Chhattisgarh is served by CSPDCL, but some tribal areas are served by CSPTCL. Confirm your connection type (domestic, commercial, industrial) is eligible for net metering.
Assess rooftop suitability and structural capacity
Conduct a shadow analysis to estimate generation. Engage a structural engineer to verify the roof can support 15–20 kg/m². Chhattisgarh’s flat terrain means minimal shading from surrounding hills, but neighbouring buildings must be considered.
Select a CSPDCL-empanelled vendor
For residential systems claiming subsidy, choose from CSPDCL’s empanelled vendor list. For C&I systems, any MNRE-approved vendor can be used, but CSPDCL registration simplifies the process. Request references and visit completed installations.
Submit net metering application online
Apply through cspdcl.co.in with: application form, ownership proof, latest bill, SLD, equipment datasheets, and structural certificate. Pay ₹1,000 (residential) or ₹5,000 (C&I). Track status online.
Install and commission with CSPDCL
Install through the empanelled vendor. CSPDCL inspects within 10 working days of installation completion. After passing inspection, the bidirectional meter is installed and the system is commissioned. You will receive a commissioning certificate.
Claim subsidies through the national portal
For residential systems, apply for PM-Surya Ghar subsidy through pmsuryaghar.gov.in. Upload the commissioning certificate, installation photographs, and bank account details. Subsidy is typically disbursed within 30 days of verification.

Frequently Asked Questions
What is the net metering policy in Chhattisgarh?
Chhattisgarh allows net metering for rooftop solar systems up to 1 MW capacity under CSERC regulations. The Chhattisgarh State Power Distribution Company (CSPDCL) is the nodal agency for net metering applications. Consumers receive credits for exported energy at the average power purchase cost (APPC) rate, which is approximately ₹3.50–4.50/kWh. The state has a simplified single-window clearance process for rooftop solar installations below 10 kW.
What subsidies are available for solar in Chhattisgarh?
Chhattisgarh residents can access the Central Financial Assistance (CFA) under the PM-Surya Ghar Muft Bijli Yojana: ₹30,000/kW for systems up to 2 kW, and ₹18,000/kW for additional capacity up to 3 kW (maximum ₹78,000 for 3 kW). The state government also offers an additional subsidy of ₹10,000/kW for residential systems up to 3 kW under the Chhattisgarh Solar Energy Policy. For group housing societies, the subsidy is ₹18,000/kW up to 500 kW. Commercial and industrial customers are not eligible for state subsidies but can claim accelerated depreciation.
How do I apply for net metering with CSPDCL?
Apply through CSPDCL’s online portal (cspdcl.co.in) or at the nearest CSPDCL division office. Submit: net metering application form, proof of ownership/occupancy, latest electricity bill, single-line diagram endorsed by a registered electrical contractor, equipment datasheets (MNRE-approved), and structural stability certificate (for rooftop). CSPDCL conducts a technical feasibility study within 15 working days. After approval, install the system through a vendor registered on the state’s empanelled vendor list. CSPDCL inspects and commissions the system within 10 working days of installation completion.
What is the solar potential in Chhattisgarh?
Chhattisgarh receives an average of 5.0–5.5 peak sun hours per day, with annual solar irradiance of 1,500–1,700 kWh/m². The state has significant potential for both rooftop and utility-scale solar. Raipur, Bilaspur, and Durg-Bhilai are the primary urban centres with C&I demand. The state’s power-intensive industries (steel, cement, aluminium) create strong demand for open-access and captive solar. Chhattisgarh’s target is 1,500 MW of solar capacity by 2027 under its Solar Energy Policy.
Are there any restrictions on rooftop solar in Chhattisgarh?
Rooftop solar in Chhattisgarh must comply with: maximum system capacity of 1 MW for net metering, rooftop structural load capacity (minimum 15 kg/m²), setback requirements from roof edges (minimum 1 metre), height restrictions in heritage zones (Raipur Old City, Sirpur), and clearance from the fire department for systems above 50 kW. Ground-mounted systems on private land are permitted but require conversion of land use from agricultural to commercial if the land is classified as agricultural.
