Jetpur is a textile printing town, and a printing hall's roof and load pattern are quite different from a family home's. The case for solar there depends on daytime electricity use, not on the subsidy.
Jetpur-Navagadh is known for cotton sarees, screen and block printing, dyeing, and the khanga and kitenge fabrics it exports to Africa. The Jetpur Dyeing and Printing Association is based at Kanakiya Plot, and a second industry body, the Dhareshwar GIDC Area Association, sits on the Navagadh side. The municipality's own records also mention embroidery, a transport trade built around the saree business, and diamond units.
A TERI cluster study published in 2015 found that most energy in the printing cluster is heat from boilers and thermic fluid heaters. These are fired with wood, biomass briquettes and lignite, and electricity makes up only about a sixth of the total. Rooftop solar does not replace that heat. What it does replace is grid power for fans, printing machines, pumps, lights and utilities. The same study notes that cold-table units print only in daylight, roughly 8 am to 5 pm, which lines up closely with solar generation.
Commercial and industrial connections cannot use PM Surya Ghar. They can claim accelerated depreciation on the system, and a zero down payment structure can keep the monthly instalment below the power cost it removes.
- Long printing sheds need a structural check of purlins and sheeting before a rating is quoted.
- An on-grid inverter shuts down when grid power fails, so a diesel generator remains your backup.
- Roofs near boiler chimneys need cleaning frequency written into the maintenance contract.
