Cut Power Costs by Up to 90%. Recover Your Investment in 3-5 Years.
Industrial electricity tariffs in Tamil Nadu are among the highest in the country. A well-planned solar installation can reduce your monthly power cost by 70 to 90 percent – and pay for itself in three to five years.
A solar installation on your factory roof or commercial complex turns unused rooftop space into a power generation asset. It produces electricity during your working hours, directly offsetting your most expensive consumption and reducing peak load charges. The power you save is profit returned to your business.
On-Grid Commercial Solar
An on-grid solar system for industry or commercial use connects your rooftop directly to your existing EB connection. During operational hours, your facility runs on solar power, reducing your drawn units and your bill. On-grid systems offer the highest financial return for businesses with consistent daytime operations. There are no battery costs, and the system delivers maximum kilowatt-hours per rupee invested.
By eliminating battery overheads, your business achieves a much shorter payback period and higher long-term return on investment. Furthermore, any excess power generated during holidays or low-consumption days can be seamlessly exported back to the grid through net metering. This ensures that your roof continuously generates economic value for your company even during operational downtime.
Factories, warehouses, textile mills, IT parks, and any commercial facility that operates primarily during daylight hours.
Hybrid Commercial Solar
A hybrid system adds battery storage to your solar setup, providing crucial power backup. This is particularly valuable for facilities requiring uninterrupted power during grid outages, or businesses wanting to reduce expensive diesel generator dependency. A hybrid system stores solar energy during the day and deploys it during critical peak windows, helping you bypass high-tariff units.
For commercial complexes, hybrid solar is especially effective in managing steep peak-hour tariffs. TANGEDCO applies significantly higher charges during evening peak consumption windows (typically 6 PM to 9 PM). By discharging stored battery power during these precise hours, your business can systematically flatten its peak demand charges and insulate itself from the highest utility rates.
Commercial complexes with evening peak loads between 6 PM and 9 PM, large-format retail stores, cold storage, food processing, pharmaceutical units, hospitals, and any facility where power continuity or tariff management is critical.

Your Solar Energy - Available Day & Night, and Cut Costs by 50%
24/7 power from Solar and Storage
Surplus solar energy stored during the day keeps your business running through the night, during outages, and through grid fluctuations , without a single unit drawn from the EB.
Cut electricity costs by 50 percent
Battery storage enables peak shaving and dramatically increases solar self-consumption, reducing your dependence on expensive grid units during high-tariff hours. Peak load tarifs
Reliable power for critical operations
For businesses where grid instability means halted processes, equipment damage, or revenue loss, storage provides the continuity that a standard solar system alone cannot guarantee.
Stronger sustainability credentials
Higher clean energy consumption through storage directly supports RE100 commitments, net-zero targets, and ESG reporting - making your green energy claim measurable, not just aspirational.

The Tax Advantage That Strengthens Your Investment in Solar
Under the Income Tax Act of India, solar power systems installed by businesses are eligible for accelerated depreciation. A business can claim up to 40 percent depreciation on the solar system value in the first year of installation. This reduces taxable income significantly and effectively lowers the net cost of the project for profitable companies.
For a business in the 25 to 30 percent tax bracket, the tax saving from accelerated depreciation alone can amount to 10 to 12 percent of the total project cost in year one.
