Industrial Solar Plant Installation
Factories, warehouses and manufacturing units may require larger solar installations to support their electricity needs.
Industrial projects require careful assessment of electrical loads, roof strength, available land, grid connection, equipment requirements and expected energy generation.
For a large project, ask the solar plant installation company for a detailed technical proposal, generation estimates, project timeline, safety arrangements and financial calculations.
Solar Farming and Ground-Mounted Solar Plants
Ground-mounted solar plants are installed on suitable land rather than rooftops. Their feasibility depends on land availability, site conditions, grid connectivity, project permissions and financial viability.
These projects differ from ordinary residential rooftop installations and may require specialised engineering and regulatory support.
On-Grid, Off-Grid and Hybrid Solar Systems
There are three common solar system configurations.
- On-grid solar: Connected to the electricity grid. It can reduce grid electricity consumption, but a standard grid-connected inverter generally shuts down during a grid outage for safety.
- Off-grid solar: Uses batteries to store electricity and can operate independently of the grid when appropriately designed.
- Hybrid solar: Combines grid connectivity with battery storage, subject to the system design and equipment capabilities.
SaurSetu helps customers explore different solar configurations based on their power requirements, location and budget.
Solar Panel Installation Cost in India
The cost of solar installation depends on several factors. These include system capacity, panel specifications, inverter type, mounting structure, roof condition, wiring, electrical protection equipment and installation complexity.
A small residential rooftop system will generally require a different investment from a commercial or industrial solar plant.
Factors That Affect Solar Installation Cost
1. Solar system capacity
The required capacity, measured in kilowatts (kW), is a major cost factor. The appropriate size depends on electricity consumption, roof space and the system’s expected generation.
2. Solar panel technology

Government Subsidy for Rooftop Solar Installation in India
Government assistance can reduce the upfront cost of eligible residential rooftop solar systems. One important initiative is the PM Surya Ghar: Muft Bijli Yojana.
The scheme provides financial assistance to eligible residential consumers, subject to applicable guidelines and verification requirements. The subsidy is not automatically available for every solar project, business or system configuration.
Under the scheme’s published central subsidy structure, eligible residential systems generally receive assistance calculated for the first 2 kW and an additional 1 kW, with no additional central subsidy for capacity above 3 kW under that standard structure. The applicable amount and eligibility must be confirmed against current official guidelines. Official MNRE guidance and the PM Surya Ghar portal provide authoritative scheme information.
Who Can Apply for Rooftop Solar Subsidy?
Eligibility depends on the applicable scheme rules, the consumer’s electricity connection, the type of installation and compliance with required procedures.
Residential consumers should check the latest official eligibility requirements before purchasing a system.
Commercial and industrial customers should not assume that the residential subsidy automatically applies to their projects.
How a Solar Installation Company Helps With Subsidy
A solar installation company can guide customers through the applicable process, explain the documents required and help coordinate installation and verification activities.
SaurSetu provides subsidy guidance and documentation support to help customers understand the process. Customers should confirm the applicable vendor requirements, installation specifications and responsibilities before proceeding.
Basic Steps to Apply for Rooftop Solar Subsidy
- Visit the official PM Surya Ghar portal and review the latest scheme requirements.
- Complete the required application and electricity connection details.
- Follow the prescribed vendor-selection process.
- Finalise the system and complete installation in accordance with applicable guidelines.
- Complete the required inspection, commissioning or verification steps.
- Submit the necessary documents and bank details through the official process, where required.
The precise process can vary according to the applicable scheme rules and local DISCOM requirements. A subsidy should never be treated as guaranteed until eligibility and all required conditions have been confirmed.
How to Choose the Best Solar Installation Company in India
Selecting the best solar installation company in India requires more than comparing brand names. The installer should understand your project, provide suitable equipment and explain the responsibilities involved.
1. Check Experience and Credentials
Review the company’s legal identity, previous projects, technical capabilities and relevant registrations.
For installations under a government scheme, verify the applicable vendor registration or empanelment requirements through the official portal or relevant DISCOM.
2. Compare Panel and Inverter Quality
Check the specifications, compatibility, product documentation and applicable warranty terms of the proposed equipment.
Ask the company to explain why the selected components are suitable for your location and electricity requirements.
3. Evaluate Installation Quality and Safety
Good installation practices are essential for safe operation and long-term performance.
Check whether the proposal addresses roof strength, mounting quality, wind-load considerations, earthing, electrical protection and appropriate cable routing.
4. Review Warranty and After-Sales Service
Understand the difference between the solar panel product warranty, inverter warranty and installation workmanship coverage.
Ask who will handle repairs, how service requests are raised and whether maintenance visits or an annual maintenance contract are included.
5. Read Reviews and Check Previous Projects
Look for genuine customer feedback and completed projects similar to your requirements.
A company that has experience with residential rooftops may not automatically be the best choice for a large industrial plant.
6. Demand Transparent Pricing
A written quotation should clearly explain the equipment, work, exclusions, payment terms and expected timeline.
Avoid making a large payment without a clear agreement and documented responsibilities.
SaurSetu aims to simplify this process through solar consultation, installation coordination, subsidy guidance and post-installation support. Customers should still review the project proposal and confirm all terms before proceeding.
Solar Panel Installation Process: Step by Step
A well-managed installation follows a planned process.
Step 1: Electricity consumption assessment
