Recently I had the opportunity to be at Mount Abu, a small hill-station near Udaipur.
Most of the hotels in the small town had solar water heaters on their roof-top. The hotels are proud of their solar installations and promote this through their brochures and websites. Surely, the solar water heaters help hotels give hot water service to clients and also cut their operating costs.
Meanwhile, the shops at the main market of Mount Abu were without electricity during the main shopping hours in the evening. The bigger shops had generators running to attract clients whereas the smaller shopkeepers had kerosene lamps burning or just stood ground during the dark hours.
With acceptance of solar (water heaters), maybe solar developers could look at solar pv power plants under pay-per-use schemes; with micro-grid system. The developers/investors will not face the first hurdle of acceptance.
But then we will also encounter the problem of energy usage during peak hours- and in such towns the peak hour is after sunset when solar energy is not being generated.
Guess like any other application, solar energy will also need to be customized as per the culture, lifestyle and habits of the city/town.
