What Do Solar Companies Do?
At their core, solar companies design, supply, and install solar energy systems. Their offerings usually include:
Solar panel manufacturing or sourcing
System design and customization
Installation services (residential, commercial, industrial)
Maintenance and servicing
Energy storage solutions
Monitoring systems
Assistance with government subsidies and financing
Some focus on niche sectors like industrial solar panel installation, while others serve residential homes and rural areas. Premium brands also develop smart solutions like solar-powered appliances and solar fridges for off-grid needs.
Types of Solar Companies in India
In the Indian market, solar companies generally fall into these categories:
1. Manufacturers
These companies produce solar panels and related hardware (e.g., inverters, batteries). Many also offer EPC (engineering, procurement, and construction) services.
2. EPC Contractors
They handle everything from designing the system to commissioning and maintaining it. They’re crucial for large projects like ground-mounted solar farms or industrial rooftops.
3. Retailers and Installers
These are regional service providers that source panels and inverters and provide localized installations, especially for residential customers.
4. Turnkey Solution Providers
They combine hardware, software (e.g., smart inverters), and installation into one offering. Many also provide mobile apps to monitor systems in real time.
Key Factors to Consider When Choosing a Solar Company
Not all solar companies are created equal. Here’s what to look for:
✅ Experience & Certifications: MNRE or state-approved vendors ensure compliance with quality standards.
✅ Technology & Products: Seek companies offering the latest in solar modules and BIPV solar panels.
✅ Warranties: Panels should have a 25-year performance warranty; inverters at least 5–10 years.
✅ After-Sales Support: Maintenance, troubleshooting, and updates should be available post-installation.
✅ Project Portfolio: Browse their completed residential, commercial, and industrial installations.
✅ Transparency: Clear quotes, no hidden fees, and assistance with government subsidies.
