As solar energy rapidly gains traction across India, homeowners and businesses alike are turning to solar power to reduce electricity bills and embrace sustainability. However, with the surge in demand comes a flood of solar companies offering different products, services, and pricing models. Choosing the right solar company can be overwhelming—especially if you’re new to the world of solar.
This guide will walk you through the most important factors to consider when selecting a solar company in India, ensuring that you make an informed and confident decision.
1. Understand Your Solar Needs
Before diving into company comparisons, understand your own energy requirements:
- What is your average monthly electricity consumption (in kWh)?
- Do you want a grid-tied, off-grid, or hybrid system?
- How much rooftop space do you have?
- Do you plan to install a battery backup?
By knowing your needs, you’ll be better prepared to evaluate which company offers the most suitable solutions.
2. Verify Company Credentials and Experience
Experience matters in the solar industry. Look for companies that:
- Have at least 3–5 years of proven installation experience in India
- Are MNRE-approved (Ministry of New and Renewable Energy) vendors
- Employ qualified engineers and certified installers
- Can provide documentation of past projects
Check whether the company is registered with government subsidy programs, especially under India’s Rooftop Solar Programme Phase II, which offers financial support to residential users.
3. Evaluate Product Quality and Brands Used
The quality of your solar system depends largely on the components used. Reputable solar companies will offer Tier 1 solar panels and branded inverters.
Key components to evaluate:
- Solar Panels: Look for brands like Adani, Vikram Solar, Waaree, Canadian Solar, Trina Solar, etc.
- Inverters: Popular and reliable brands include Sungrow, SMA, ABB, Huawei, and Growatt.
- Batteries (if applicable): For hybrid or off-grid systems, ensure lithium-ion or lead-acid batteries are BIS-certified and well-reviewed.
Avoid companies that use low-quality components to cut costs, as this will impact your system’s performance and lifespan.
4. Check for Warranties and Service Agreements
A trustworthy solar company will offer strong warranties and long-term support. Make sure you get:
- Panel warranty of at least 25 years (for performance)
- Inverter warranty of 5–10 years
- Installation or workmanship warranty of 5 years or more
Also, ensure they provide after-sales service and maintenance, preferably with annual inspections or service packages.
5. Compare Quotes and Cost Transparency
Don’t settle for the first quote. Reach out to at least 3–5 solar companies and compare:
- Equipment costs
- Installation charges
- Subsidies applied
- Warranty terms
- GST and other taxes
A genuine solar company will provide a detailed breakdown of the cost and help you apply for state or central subsidies. Be cautious of companies that offer vague pricing or push you to make quick decisions.
6. Ask About Financing Options
Solar installations can be expensive upfront, but many reputable companies offer financing options like:
- Solar loans through NBFCs or banks (with EMI options)
- Pay-as-you-go models or lease agreements
- No-cost EMI schemes partnered with lenders
- Guidance on claiming state or national solar subsidies
Choose a company that helps you understand the long-term return on investment (ROI) and offers clear repayment terms.
7. Review Online Ratings and Customer Testimonials
A company’s reputation speaks volumes. Use platforms like:
- Google Reviews
- JustDial
- SolarQuotes
- Trustpilot
- Company websites or YouTube project videos
Look for consistent praise regarding:
- Installation quality
- Timely service
- Customer support
- Post-installation maintenance
Avoid companies with frequent complaints about delays, poor after-sales service, or inadequate technical support.
8. Assess Installation Process and Timeline
An efficient company will walk you through:
- Site inspection
- Load calculation
- System design and shadow analysis
- Documentation for subsidy and net metering
- Timely installation and testing
Ask how long the entire process—from consultation to commissioning—will take. Most residential systems are installed within 3–4 weeks, depending on approvals and site conditions.
9. Check Net Metering Support and Liaison Services
For grid-connected solar systems in India, net metering is essential for exporting excess power and reducing your bills.
Ensure your chosen company:
- Has experience with the local DISCOM
- Provides net metering documentation and approvals
- Helps with subsidy application (if eligible)
The best companies handle all paperwork, reducing your burden and speeding up system commissioning.
10. Look for Local Presence and Support
Choose a company with a local office or service network in your area. Local companies or national brands with local partnerships are better equipped for:
- On-site assessments
- Faster maintenance or repairs
- Handling weather and grid-specific challenges
They also tend to be more responsive than firms operating remotely or online-only.
Bonus Tip: Avoid Common Red Flags
Be wary of companies that:
- Offer unrealistic pricing or “too-good-to-be-true” discounts
- Pressure you to sign contracts without full information
- Provide no documentation or informal quotes
- Have hidden charges or non-disclosure of net metering/subsidy costs
A genuine solar company will prioritize education over sales, ensuring you understand every aspect of your investment.
