High electricity consumption is not just an energy cost issue. For many businesses, it is also part of the emissions conversion.
This is where commercial solar becomes more than a cost-saving project. A properly designed and installed solar system can become a measurable part of a company’s ESG strategy. This helps reduce dependence on conventional grid electricity, support renewable energy targets and create better visibility around environmental performance.
With evolving renewable procurement mechanisms, green open access and corporate sustainability reporting, going solar has become more like an opportunity for Indian businesses.
How?
Let’s find out below!
Why Commercial Solar Is Becoming an ESG Decision
Generally, solar is evaluated through a simple solar calculation.
Installation cost ➜ electricity generation ➜ savings ➜ payback.
Even though this calculation matters, large businesses are increasingly asking for:
- How much electricity are we sourcing from renewable sources?
- How can we reduce location-based or market-based Scope 2 emissions?
- Can our renewable energy procurement be documented?
- How does this investment support our sustainability targets?
- Can the project contribute meaningful data to ESG reporting?
India’s BRSR framework has pushed listed companies toward more quantitative and standardised ESG disclosures. SEBI’s BRSR Core introduces assurance requirements for selected ESG metrics, with the implementation glide path extending to the top 1,000 listed entities by FY 2026-27.
How Commercial Solar Supports Net-Zero Goals
1. Tackles electricity-related emissions
Commercial solar can directly serve on-site demand through rooftop or ground-mounted installations. This makes solar energy for corporate sustainability more tangible.
Instead of a sustainability target that exists mainly in a report, businesses can change how they generate or procure part of their electricity.
2. Creates measurable renewable energy generation
A good ESG strategy needs measurable outcomes.
A properly monitored solar plant can provide data such as energy generated, plant performance and renewable electricity contribution. That data can then support internal sustainability monitoring and, where applicable, external reporting.
The distinction matters.
3. Complements broader renewable procurement
India’s Green Energy Open Access framework allows consumers to procure green energy, subject to the applicable rules and regulatory conditions.
The Ministry of Power reported that, as of December 2025, more than 46,000 users were registered on the National Open Access Registry and 463 users on the Green Energy Open Access portal, illustrating the scale of open-access participation.
Commercial Solar for Scope 2 Emissions Reduction
When businesses start translating net-zero ambitions into operational actions, scope 2 often becomes a practical focus.
Purchased electricity often represents a significant part of an organization’s emissions footprint, particularly for electricity-intensive commercial and industrial operations.
Nevertheless, commercial solar can help businesses address this area by increasing the share of electricity supplied from renewable generation.
There is a detail that most commercial & industrial organizations overlook. The accounting treatment depends on the renewable electricity arrangement and the applicable emissions accounting methodology.
➤ Simply installing solar does not automatically mean every sustainability metric can be reduced by the same percentage. That is why an experienced solar EPC partner is essential.
ESG Solar Solutions for Businesses Need More Than Panels
A commercial solar project designed primarily around ESG objectives should start with the organization’s energy and sustainability requirements.
Step 1: Start With Electricity Profile
Before discussing system size, understand when your facility consumes most electricity, how much demand occurs during daylight hours, and what the sanctioned load is.
Evaluating these questions may help you determine whether rooftop solar installation alone makes sense or whether your project needs a wider renewable procurement strategy.
Step 2: Connect Energy Data with Sustainability Objective
If your organization has a defined emissions baseline, renewable-energy target or net-zero roadmap, you should evaluate the solar project against those objectives.
Solar is a long-term investment. It should fit into that roadmap rather than exist as an isolated engineering project.
Step 3: Build Monitoring into the Project
ESG claims are becoming increasingly data-driven.
Generation monitoring, energy performance, operational records and appropriate documentation can make it easier for sustainability and finance teams to track what the renewable asset is actually delivering.
Industrial Solar Sustainability in India
Industrial facilities have very different energy requirements from offices or commercial buildings. A good solar strategy needs to account for how the facility actually operates.
1. Understand Energy Consumption
Look at operating hours, production schedules, peak demand and overall electricity usage before deciding the solar capacity.
2. Match Solar With Demand
Solar generation should align with the facility’s electricity consumption as much as possible to maximise the value of renewable power.
3. Consider More Than Rooftop Solar
Large facilities can explore rooftop, ground-mounted, captive and off-grid solar systems based on their space, location and energy requirements.
4. Connect Solar With ESG Goals
Solar can support renewable energy targets and contribute to a broader strategy for reducing emissions from purchased electricity.
5. Focus on Long-Term Performance
System design, equipment quality, monitoring and regular maintenance all matter when solar is expected to perform for years.
6. Think Beyond One Solar Project
For companies working toward net-zero goals, solar can work alongside energy efficiency, storage, electrification and other renewable energy solutions.
How Businesses Can Build a Commercial Solar ESG Strategy
A practical commercial solar ESG approach can start with five simple stages:
Access ➜ Quantify ➜ Design ➜ Measure ➜ Improve
1. Access:
Map electricity consumption, demand patterns, facility locations, available rooftops or land and existing power procurement arrangements.
2. Quantify:
Establish the current energy baseline and identify the emissions associated with purchased electricity using the company’s applicable accounting methodology.
3. Design:
Evaluate rooftop solar, ground-mounted solar, open access, captive structures, storage and other relevant renewable procurement options.
4. Measure:
Track generation, renewable electricity contribution, system performance and other project-level data that can support internal sustainability reporting.
5. Improve:
Treat the solar project as part of a long-term energy programme. As electricity demand, facilities and corporate targets change, the renewable strategy should evolve too.
Ready for Corporate Renewable Energy Procurement in India?
Commercial solar should not be treated as a sustainability badge that looks good in an annual report.
It should work in the real world, on the factory roof, across the warehouse portfolio, inside the company’s energy budget and against measurable sustainability objectives.
For Indian businesses working toward stronger ESG performance and long-term net-zero goals, the right solar strategy starts with understanding where energy is being consumed, where emissions are coming from and which renewable procurement model actually fits the business.

Frequently Asked Questions (FAQs)
How does commercial solar support ESG goals?
Businesses can increase the amount of renewable electricity produced through the use of commercial solar systems; reduce their dependence on traditional grid electricity; and receive information regarding energy usage.
Can rooftop solar help a company achieve net-zero targets?
Yes. Rooftop solar may help companies achieve their goal of net-zero through reduced use of conventional power. Net-zero targets require more than rooftop solar; there is usually a much wider scope.
How does solar energy reduce Scope 2 emissions?
Solar energy reduces the amount of electricity that a company has to purchase from the grid. The real Scope 2 effect will depend on the specific accounting procedure and the renewable energy agreement.
What is the role of commercial solar in corporate sustainability reporting?
Solar can provide measurable data such as renewable electricity generation and energy consumption, which may support sustainability and ESG reporting.
Can solar installation help companies meet BRSR reporting requirements in India?
Solar alone is not enough to make an enterprise BRSR-compliant. Still, solar energy-related information about its emissions can be used for making environmental disclosures within the framework of the BRSR.
Which commercial solar model is best for ESG goals: rooftop, captive, or open access?
There isn’t a one-size-fits-all approach. The rooftop, captive, and open access need to be assessed considering the demand for electricity, space availability, location, policies, purchasing criteria, and sustainability goals. India’s policy regime accepts open access and captive consumption as ways to purchase renewable energy.
Can businesses use solar energy to reduce electricity costs and carbon emissions together?
Yes, because a properly designed commercial solar installation can help to lower the use of traditional energy sources and promote the use of renewable energy sources.
How can companies measure carbon-emission reductions from a solar project?
A company can then rely on data about solar energy generation which will be combined with an appropriate emissions factor for electricity and an accounting method. Reporting of Scope 2 should adhere to a specific GHG accounting standard.
Does commercial solar improve a company’s ESG rating or brand credibility?
Not necessarily. Solar energy can enhance a company’s performance regarding its impact on the environment as well as serve as proof of renewable energy initiatives, but there are other criteria for ESG ratings.
What should a company evaluate before investing in commercial solar for net-zero goals?
Review power usage, loading patterns, roof space or land availability, economic feasibility, renewable energy purchasing options, regulations, projected production and monitoring and maintenance requirements.
