Green Energy Solutions installed a pilot Solar Edge Grid tied system, for a factory in Midrand, in January 2015.
This system will be used to create actual production data, which will then be used to determine the financial viability and ROI of a larger system. As they are on a time of use based tariff, having actual production data will create an accurate indication of what a larger system can do for them.
The size of the system is 5 kWp, with a 3 phase SolarEdge inverter.
The cost of the system was around: R120 000.00
Monthly they are saving on average 800 kWh off their electricity bill.
Giving a payback or around 8 years.
As this is a small pilot project, the cost per installed kWp is relatively high.
The cost per installed kWp does come down with larger installations, causing the payback period to decrease to around 6 or 7 years.
Instantaneous and historic energy production reporting available on the Solar Edge monitoring portal.
Solar Edge reports the production for each panel. This makes monitoring and trouble shooting much easier.
