However, before jumping into the blog, most business owners have wavering questions such as:
- Which is the best solar system for the commercial sector?
- How many kilowatts (kW) of solar capacity do I need for my industry or my organization?
- What is the cost of rooftop solar panels, and what is the cost of installation?
- How much roof space do I need?
- Who will provide maintenance and after-sales service?
In this blog, we will cover everything you need to know about commercial and industrial solar rooftop solutions,
from the types of systems you can install to the benefits of solar rooftop installations, pricing, and government subsidies.
How Rooftop Solar Works for Businesses
A rooftop solar system is simply a solar panel on the roof of a commercial or industrial building.
These solar panels transform sunlight (which, let’s remember, is a renewable energy source) into direct current (DC) electricity,
which they produce at a suitable voltage or current and convert into rotating current (AC) using grid-interactive inverters.
The electricity can then be utilized for powering industrial machinery/lighting, or office equipment, even with no electricity.
Types of Power Flow
- On-Grid Solar System for the Commercial Sector: Excess electricity can be passed back to the grid using
net metering.
- Off-Grid Rooftop Solar Panels: Energy can be stored in batteries, providing a guarantee of supply
in areas with unreliable grid power.
- Hybrid Solar Systems: Combine both grid connectivity and battery backup
for more reliable power.
All the reasons above are why you should install rooftop solar panels on the roof of your factories,
offices, warehouses, schools, malls, and all kinds of industries.
Types of Rooftop Solar Systems for Commercial & Industrial Use
If you are looking for different types of solar panels and wondering which one is better for you,
we have mentioned below the Types of Rooftop Solar Systems. You can choose the best one as per your requirement.
1. On-Grid Commercial Rooftop Solar Systems
- These panels are directly connected to the grid.
- Best suited for industries in urban areas where grid electricity is stable.
- Lower upfront cost because batteries are not required.
2. Off-Grid Solar Rooftop Systems
- Fitted with battery storage.
- Perfect for remote areas that face frequent power cuts.

Industries Benefiting from Rooftop Solar
Rooftop solar provides the highest value to the industrial sector for those industries
that consume large amounts of electricity, such as:
- Manufacturing and Processing Plants
- IT Parks and Corporate Offices
- Shopping Malls and Retail Chains
- Cold Storages and Warehouses
- Hospitals and Healthcare Centers

How to Calculate the Required Solar Capacity
The solar capacity needed depends on:
- Monthly electricity consumption.
- Rooftop available area
- Type of solar system
Rule of Thumb:
1 kW rooftop solar requires ~100 sq. ft. of roof space and generates
4–5 units per day.
Example:
- A factory depleting 30,000 units/month may require a 200 kW rooftop solar system.
- This would need about 20,000 sq. ft. of roof space.
At Contendre Solar, we provide free site surveys and our experts can guide you and give the best suggestion according to your requirements, which will help your businesses in calculating the right capacity.
Installation Process for Rooftop Solar in Commercial & Industrial Facilities
Rooftop solar installation starts with a site evaluation, where expert technician team assesses roof space, structural conditions, and other factors in detail. Like
- Initial Consultation & Site Visit
- Energy Audit & System Design
- Supply of Rooftop Solar Panels, Inverters & Accessories
- Rooftop Solar Installation by certified engineers
- Testing, Commissioning & Grid Connection
- Handover with Training & Monitoring Setup
With Contendre Solar, the entire process is managed end-to-end without hassle.

Cost of Rooftop Solar for Commercial & Industrial Applications
The price of commercial rooftop solar systems varies based on size, quality, and type:
- Small Office (10–20 kW): ₹4–10 lakhs
- Medium Factory/Warehouse (50–100 kW): ₹20–50 lakhs
- Large Industry (500 kW–1 MW): ₹2.5–5 crores
For example, a 100 kW system would save an average business ₹12 - 15 lakhs on just electricity bills a year,
and your business can have the ROI in less than four years.
