SUNfarming designed and installed a high quality 130kWp grid tied system at Pick & Pay Potchefstroom, one of the leading supply chain supermarkets in South Africa. SUNfarming used a designed methodology to maximize the yield output by elevating the solar modules. Elevated modules not only ensure optimal irradiation and effective ventilation under the panels, it also minimizes the maintenance cost during the life time of the system.
The system produces an average 10% more than pre-calculated. During the last four months, Pick & Pay saved 86 MWh of electricity with an overall reduction in consumption of 18%. During the lifetime of the system the client will generate a return of approximately more than 20% on the cash flow saving of this initiative.
The saving benefit per year is about R340.000 with a 6 year payback period.
