* State policies are updated frequently. Check with your local DISCOM or state nodal agency for the latest subsidy and net metering rules.

Solar Financing & EMI Options

Cannot afford the full upfront cost? Multiple financing options make solar accessible to every Indian household:

Solar Loans from Banks

SBI, PNB, Bank of Baroda, and other nationalized banks offer dedicated solar loans at 7-9% interest with repayment up to 10 years. Some offer collateral-free loans up to ₹10 lakh for rooftop solar.

NBFC & Fintech Solar Loans

Companies like Tata Capital, Bajaj Finance, and specialized solar fintechs offer easy EMI options. EMI typically works out to less than your current electricity bill, making it a net-positive investment from day one.

Solar Leasing / RESCO Model

Under the RESCO (Renewable Energy Service Company) model, a company installs solar on your roof for free. You simply pay a per-unit rate lower than your grid electricity cost. Best for those who cannot afford upfront investment.

Pay-As-You-Save Model

Some solar companies offer zero-down-payment installations where your monthly EMI is designed to be equal to or less than your current electricity bill savings, making solar effectively free from month one.

Pre-Installation Checklist

Going solar? Use this checklist to make sure your home is ready for solar panel installation:

Confirm your roof gets 4-5 hours of direct, shadow-free sunlight daily.
Ensure the roof is structurally sound — each panel weighs 20-22 kg plus mounting structure.
Check for shading from nearby buildings, trees, water tanks, or satellite dishes.
Verify your electricity connection is in your name (required for net metering and subsidy).
Keep your last 6 months electricity bills ready — installers need them to size your system.
Check if your local DISCOM supports net metering (most DISCOMs across India do).
Ensure roof waterproofing is intact — fix any leaks before panel installation.
Identify a cool, ventilated, accessible indoor location for the inverter.
Register on the PM Surya Ghar Yojana portal (pmsuryaghar.gov.in) before installation.
Budget for full upfront cost — the government subsidy (up to ₹78,000) is reimbursed to your bank account 30-60 days after installation and inspection.

Tips for Choosing a Solar Installer

1

Check MNRE Empanelment

Ensure your solar installer is empanelled with the Ministry of New and Renewable Energy (MNRE) or your state nodal agency. This is mandatory for PM Surya Ghar Yojana subsidy eligibility.

2

Get 2-3 Written Quotes

Always compare quotes from multiple installers. Check system size (kW), panel brand, inverter brand, mounting structure quality, warranty terms, and total cost including GST.

3

Verify Past Installations

Ask for photos and addresses of at least 5 previous installations. Visit one if possible. Reputable installers proudly share their portfolio and connect you with past customers.

4

Insist on Tier-1 Panels

Choose BIS-certified, Tier-1 solar panels from reputed brands like Waaree, Tata Solar, Adani, Vikram Solar, or Luminous. Avoid unknown Chinese brands that lack proper warranty support in India.

5

Understand All Warranty Terms

Solar panels: 25-year performance warranty. Inverter: 5-10 years. Mounting structure: 10-15 years. Installation workmanship: minimum 2-5 years. Get everything in writing before paying.

6

Confirm Complete Subsidy Handling

A good installer handles everything — PM Surya Ghar portal registration, DISCOM feasibility application, net meter installation, DISCOM inspection, and subsidy claim submission.

7

Follow the Right Payment Schedule

Standard terms: 30% token advance, 50% after panel and inverter delivery to site, 20% after commissioning and net meter activation. Never pay 100% upfront.

8

Check After-Sales Support

Ask about annual maintenance contracts (AMC), remote monitoring setup, response time for complaints, and who to contact for inverter or panel issues. Good after-sales service is as important as good installation.

Solar Energy Glossary — Key Terms Explained

Understanding solar energy terminology helps you make better decisions and communicate effectively with your solar installer.

Net Metering

A billing system where excess solar power you generate is exported to the grid, and you receive credits on your electricity bill. Your meter runs both ways — forward when consuming, backward when exporting.

On-Grid (Grid-Tied) System

A solar system connected to the electricity grid via net metering. Most affordable option and eligible for government subsidy. Does not work during power cuts unless paired with a battery.

Off-Grid System

A standalone solar system with battery storage that works independently of the grid. Higher cost due to batteries. Ideal for remote areas or locations with unreliable electricity.

Hybrid Solar System

Combines grid connection with battery backup. Works during power outages and supports net metering. Highest upfront cost but maximum flexibility and energy security.

Solar Inverter

Converts DC electricity from solar panels into AC electricity used by home appliances. Types: string inverters (most common), micro-inverters (panel-level), and hybrid inverters (with battery support).

kWp (Kilowatt Peak)

The rated maximum power output of a solar system under standard test conditions. A 1kWp system generates approximately 4-5 units (kWh) of electricity per day in most Indian cities.

DISCOM

Distribution Company — your local electricity provider (e.g., MSEDCL, BSES, BESCOM, KSEB, TANGEDCO). DISCOM approval is required for net metering and grid-connected solar systems.

MNRE

Ministry of New and Renewable Energy — the central government body that sets renewable energy policies, maintains the list of empanelled solar installers, and runs the PM Surya Ghar Yojana.

BIS Certification

Bureau of Indian Standards certification mandatory for solar panels and inverters sold in India. Ensures product quality, safety, and performance standards. Always buy BIS-certified equipment.

Tier-1 Solar Panel

Classification by Bloomberg New Energy Finance (BNEF) for solar manufacturers with strong financials, vertical integration, and reliable warranty support. Indian Tier-1 brands: Waaree, Tata Solar, Adani, Vikram Solar.

Solar Irradiance

The amount of sunlight energy received per square meter. India receives 4-7 kWh/m²/day — among the highest globally. Western and Southern India get the best solar irradiance.

DCR (Domestic Content Requirement)

Government rule requiring solar cells and modules to be manufactured in India to qualify for PM Surya Ghar Yojana subsidy. Ensures the subsidy supports Indian solar manufacturing.

Sanctioned Load

The maximum power (in kW) your electricity connection is approved for by your DISCOM. Your rooftop solar system size is typically limited to your sanctioned load for net metering eligibility.

Bi-Directional Meter

Also called a net meter or smart meter. Records both electricity consumed from the grid and excess solar power exported to the grid. Installed by your DISCOM after solar system commissioning.
