Solar Parks: On-site savings from an off-site solar park
Date:15-Apr-2026, Author: Orb Energy
For many growing businesses the intent to shift to renewable energy is clear, but practical constraints often stand in the way. Limited rooftop space, structural challenges, leased premises, or high energy demand that exceeds on-site capacity can make adoption of sufficient rooftop solar challenging.
This is where off-site solar parks emerge as a smart, scalable alternative, allowing businesses to consume clean energy generated elsewhere, while still getting the cost benefits on-site.
What are Off-Site Solar Parks?
Off-site solar parks allow a business to own a dedicated solar power plant in a large, utility-scale solar park, located in a high-irradiation region and connected directly to the grid. The power generated at the solar park is transmitted through the grid and adjusted against the electricity consumed (on-site) at the factory or plant, as per applicable regulations.
In simple terms, businesses get the financial benefits of solar power on-site without having to install the system on their premises.
This model is particularly relevant for:
- Manufacturing units with high power loads that exceed the capacity of their rooftops.
- Companies operating from leased or multistorey facilities.
Why Solar Parks Work Well
- Scales with production growth: Solar parks are not limited by rooftop size. Manufacturers can invest in megawatt-scale capacity that grows with their production needs.
- Excellent generation and strong economics: Solar parks are built in locations with optimised solar irradiation and engineered for high performance. One can expect an estimated 18% IRR and 5-year payback.
- Predictable power costs: Industrial electricity tariffs in India tend to rise over time. Off-site solar helps lock in a large portion of power costs, reducing long-term exposure to tariff increases, which is an important advantage for businesses operating on thin margins.
- Tax Benefit: Off-site solar projects qualify for accelerated depreciation under applicable tax laws in India. This allows businesses to depreciate a significant portion of the asset value in the initial years, reducing taxable income and improving post-tax returns.
- Sustainable: Off-site solar helps businesses reduce their carbon footprint by lowering dependence on grid power generated from fossil fuels. For manufacturers, especially those supplying to large corporates or export markets, this supports ESG commitments, customer sustainability expectations, and compliance with evolving reporting norms.
How Orb Energy Simplifies Off-Site Solar Parks
For many businesses, the biggest concern with off-site solar is complexity, be it land acquisition, approvals, grid connectivity, or long-term operations. Orb Energy addresses this by managing the entire project lifecycle.
Orb’s role includes:
• Identifying and acquiring suitable land.
• Securing all statutory approvals and government orders.
• Transferring land, GO and project ownership to the customer.
• Designing and building the solar park and grid infrastructure.
• Providing long-term operations and maintenance support including after-sales service.
Projects can also be structured to align with business cash flows, enabling businesses to adopt solar without putting undue pressure on working capital, while retaining ownership of the asset.
Designed for Reliability and Factory-Grade Operations
Manufacturing businesses depend on consistent power. Solar parks must therefore be built as long-term infrastructure assets.
Orb’s solar parks are designed with:
• 110 kV grid connectivity for stable and scalable power evacuation.
• High-efficiency solar modules and robust mounting structures.
• Individual metering for each customer, ensuring accurate accounting.
• SCADA-based monitoring for real-time visibility into generation and performance.
• Comprehensive safety systems, including earthing, lightning protection, drainage, and site security.
• Reliable operations and maintenance over the long-time.
This ensures reliable generation and predictable performance over a 25+ year operating life.
Solar Park Benefits Beyond Cost Reduction
For MSMEs and manufacturers, off-site solar parks support multiple business objectives:
• Lower operating costs and improved margins.
• Compliance with buyers’ green energy requirements.
• Tax efficiency through accelerated depreciation, subject to applicable tax laws.
Many businesses also combine rooftop and off-site solar to meet an even larger share of their total electricity demand through solar energy.
Solar Parks are a Practical Step Toward Long-Term Energy Cost Control
For high power consuming businesses with limited roof space, off-site solar parks are not a replacement for rooftop systems but a natural next step when power demand grows beyond on-site limits.
By offering scale, predictability, and long-term savings, solar parks enable manufacturers to take control of their energy costs while continuing to focus on what matters most: running and growing their business.
With integrated execution and long-term operational support, Orb Energy enables businesses to adopt off-site solar parks with confidence and clarity.
