Rooftop photovoltaic (PV) systems : a cost–benefit analysis study of industrial halls

Rooftop photovoltaic (PV) systems can be readily deployed on industrial halls with a relatively large rooftop area. The feed-in tariff above the base price of electricity is offered in many countries to subsidize the high initial investment of PV systems. To fully capitalize the benefit of the feed-in tariff, the investigation of the actual performance of PV systems under case-specific conditions is very important. With building energy simulation, this paper explores the cost–benefit of implementing PV systems of different capacities for a few different cases of industrial halls. The impact of various economic parameters is also investigated.
