GWGEM supports the SECS/GEM capabilities as specified in the latest published SEMI standard E30 as well as the SEMI PV2 standard which is a variation of GEM for the Photovoltaic industry. PEER Group’s involvement in SEMI standards activities provides users with regular updates, ensuring ongoing product compliance.
