Different bills, different math
Residential tariffs and commercial tariffs are priced differently, which changes the payback calculation. Commercial and industrial consumers often pay a higher per-unit rate, which can mean solar pays for itself faster on a business roof than on an equivalent-sized home system.
Subsidy applies differently
The PM Surya Ghar capital subsidy is designed for residential rooftop systems. Commercial and industrial installations are typically evaluated on pure return-on-investment instead, since they don’t carry the same subsidy structure — but the larger scale often more than makes up for it.
Load patterns matter
Homes tend to use more power in the evening, while offices and factories consume most of their power during the day — exactly when solar generates the most. This makes commercial and industrial rooftops particularly well-suited to solar, since more of the generated power is used directly rather than exported.
Either way, sizing is the key decision
Whether it’s a home or a business, the right system size comes down to your actual consumption pattern, not just available roof space. Our free site survey and consumption analysis apply the same rigor to both residential and commercial properties.
