3 kW Supplementary Grid-Tied Photo-Voltaic System

Description:

This system is a domestic scale supplementary solar system which can be utilised with a rotary disc meter or a prepaid meter. The  DC power from the solar panels is converted to AC power for direct usage by your house. A Current Transformer is included that can prevent grid-feed, in the case of prepaid meters. The system has no back-up component and will only produce power while the sun is shining and the Eskom grid is available.

Performance: 

This system will produce on average 18 kWh per day. Assuming all this energy is consumed through the daytime or stored on the grid, this would equate a saving of approximately R 1 665.00 per month (base on a municipal tariff of R 3.08 / kWh, VAT incl.). This means a basic payback of 27 months based on a yearly Eskom increase of 10%.
