PID is being talked about more and more in our industry. Tsachy Hacohen Meler, V.P. Sales & Marketing, Vigdu Technologies LTD, invited PES to come and discover the latest way to avoid financial losses and improve efficiency. It seems there’s a new approach to PID, more so as the 1500V is now in play.
PES: Hi Tsachy, welcome to PES Solar/PV, it’s great to talk with you. Could you begin by giving us a brief overview of Vigdu?
Tsachy Hacohen Meler: Established in 2014 and based in Israel, Vigdu concentrates on R&D and the manufacturing of optimization resolutions for PV plants. We started with
PID solutions, which we sell globally. We are pleased to say that our customers vary from inverters and PV module manufacturers, PV plants owners, to EPC’s & O&M’s.
We supply embedded anti PID solutions with both day and night mode technologies.
It’s an exciting time for us, because at the moment we are in the midst of significant patent-protected developments for the optimization of PV plants.
PES: Can you explain why you believe it’s smarter and cheaper to use PID preventive measures from the planning stage?
THM: We know for many years PID (Potential Induced Degradation) severely damages the performance and financing of PV plants.
After years of experience, 2017 was the turning point in both perspective and execution. This is when PV developers, EPC’s, PV plants owners, banks and insurance companies, reached the conclusion, that PID damages were worse than previously thought. They realized PID should be avoided by default preventive measures from the planning stage of the plant, just like inverters and modules. Instead of once non-refundable financial losses and physical damage had already occurred.
