A year after commissioning the solar PV system on the roof of our old office buildings, we decided to analyse the true returns generated from a system using quality products. We were surprised and pleased at what we found, considering that we had one of the wettest years on record! The install used a combination of 88 Suntech solar panels and two SMA inverters using a K2 speedrail mounting system. The payback time, based on first year revenue returns and energy savings was estimated at 4.2 years.
