This 10kVA grid-tied system exports energy back into the grid when not used on site.
The City of Cape Town rewards this type of system with a lower rate per kWh. Customers with electricity bills above R800 per month can profit from a system like this. Depending on the total electricity consumption and the size of system the pay-back period is less than 5 years.
