The Burden of Commercial Power Tariffs in Bihar
Commercial electricity consumers (Tariff NDS / CS) in Bihar face rates between ₹8.00 and ₹9.50+ per unit, alongside heavy connected load charges. For air-conditioned showrooms, textile stores, and supermarkets, electricity is often the second-largest operational expense after rent.
Why Solar Matches Retail Business Hours Perfectly
Unlike residences where peak usage often occurs in the evening, commercial shops operate predominantly from 10:00 AM to 8:00 PM. Solar generation peaks between 11:00 AM and 3:30 PM — aligning 1:1 with peak showroom AC and lighting demand.
Tax Benefits: 40% Accelerated Depreciation
Commercial enterprises can claim 40% Accelerated Depreciation (AD) on solar assets in the first year under Section 32 of the Income Tax Act, significantly lowering annual corporate income tax liabilities.
Typical ROI and Payback Period
Due to higher commercial electricity tariff rates, commercial solar installations in Bihar typically achieve full capital payback in just 2.5 to 3.5 years, delivering pure free electricity for the remaining 22+ years of the panel warranty period.
