Rooftop Solar Offers Significant Savings for Uttar Pradesh Industries

Commercial and industrial consumers in Uttar Pradesh can reduce electricity costs substantially by installing rooftop solar, with a levelized cost of energy (LCOE) of ₹2–₹2.10 per kWh against landed grid tariffs of ₹7.2–₹7.9 per kWh. The state permits installations up to 2 MW, subject to contract demand and regulations, creating a clear pathway for businesses to offset grid consumption.

How much can Uttar Pradesh industries save with rooftop solar?

The gap between solar LCOE and grid tariffs creates significant savings potential. However, realizing those savings depends on three decisions: choosing the right procurement model, securing financing, and sizing the system to actual demand. Rahul Makahaniya of Soleos Energy identifies procurement model selection as the primary challenge, followed by financing and regulatory compliance. Companies typically prefer the capital expenditure (CAPEX) model for projects below 5 MW, while larger projects tend toward operating expenditure (OPEX) arrangements. Renewable energy projects qualify for priority sector lending under the Reserve Bank of India framework, though businesses with weaker balance sheets may still face credit constraints.

Why does module quality matter more than price per watt?

Ashad Mofiz of RPSG Solvanta warns that module prices and rated efficiencies should not be the only procurement criteria. Buyers must evaluate degradation rates, warranties, reliability, and total electricity generation over the system’s operating life. Higher-wattage modules can deliver approximately 20 percent more power in certain configurations, reducing balance-of-system costs and LCOE. Actual generation, however, may run 10–15 percent below standard test condition ratings depending on irradiance and installation conditions. Makahaniya adds that mounting structure angles, historical irradiance data, and long-term generation estimates — using P50, P70, and P90 assessments — are essential for credible financial modelling.

What is the risk of oversizing or undersizing a rooftop system?

Mofiz notes that businesses often size installations without analysing consumption patterns. A consumer with a 100 kW connected load may need only 30–40 kW during peak solar hours, with higher demand in the evening. An oversized system generates surplus that may be exported at low compensation rates or curtailed, eroding returns. An undersized system leaves too much demand on expensive grid power. Mofiz insists designs must follow individual consumption profiles, and consumers with substantial evening loads should consider hybrid solutions.

Can solar-plus-storage replace diesel backup?

Diesel generation costs ₹25–27 per kWh, while renewable electricity combined with battery storage costs an estimated ₹13.5 per kWh, including roughly ₹8 per kWh for the battery. Under these assumptions, solar-plus-storage could cut backup power costs by 46–50 percent compared with diesel. Makahaniya cautions that rooftop solar-plus-storage economics remain sensitive to battery pricing and utilisation patterns.
