eIQ Energy DC parallel system at 1.2 MW solar PV installation

eIQ Energy has supplied its vBoost DC Parallel System for the 1.2 MW solar photovoltaic (PV) system at Granite Construction Inc's aggregate and hot mix facility in Coalinga, California, USA.

eIQ Energy's vBoost DC Parallel System is used to boost the output voltage of the copper indium selenium (CIS) thin-film solar modules from Solar Frontier to the optimum level for the array’s central inverters, supplied by Siemens.

The solar PV installation is expected to offset up to 50% of the Granite facility’s total energy requirements.

“This project is the largest demonstration of the cost benefits of using distributed electronics to connect solar modules in parallel,” says Oliver Janssen, Chief Business Development Officer for eIQ Energy.

“The eIQ Energy solution was less expensive to install than a comparable series architecture. Our vBoost DC Parallel System also provides long-term operational benefits by minimising the effects of shading, soiling, panel mismatch and other issues that can reduce the electricity output of panels wired in series.”
