chunk surface contaminants and offers exceptional drying capability. MEI’s Pura for Silicon finishing has significant advantages inherent in the carefully thought out design that considers not only operation, but resource use, safety, maintainability, control and flexibility.


Silicor Materials Solar Silicon


SILICOR MATERIALS has developed and proved a proprietary solar-grade silicon manufacturing process that serves as an alternative to the over-engineered electronic-grade (EG) silicon commonly used throughout the PV industry, and without sacrificing performance. The Silicor process yields a material that delivers a consistent purity; regularly


achieving in-line conversion efficiencies comparable to cells manufactured using primarily EG silicon.


polysilicon manufacturing—the Siemens process—has remained largely the same since the 1960s.


The Silicor process holds numerous advantages over the Siemens process. Silicor’s manufacturing process only requires between 10 and 25 kWh per kilogram of silicon produced, far less than the 75 and 125 kWh per kg of silicon produced required by the Siemens process.


With a production cost of less than $9/kg, Silicor’s solar silicon can increase cell and module manufacturers’ profit margins, whether it is utilized as a drop-in replacement for EG silicon or as part of a blend. The standard method of


Silicor’s solar-grade silicon is able to offer the industry’s lowest production costs while maintaining high material quality. With a production cost roughly half that of standard EG silicon offerings, Silicor enables cell and module manufacturers to, for the first time, improve profitability without performance tradeoffs.

Multi Contact AG PV Junction Box Westlake PV-JB/WL-H


MUTLI CONTACT has produced a junction box for electrical connection of horizontal ribbon conductors on crystalline modules The low profile construction of the box allows it to be installed directly under the module frame. This saves valuable time in the installation process by eliminating the need to bend the connecting ribbons.


Ribbon termination is achieved by welding, soldering, or, optionally, by terminal clips.


The box is fixed to the panel with silicone RTV. Additional protection given by the projecting cover, which prevents kinking of the cables at the point where they emerge from the cable gland.


Ribbon termination is achieved by clamping, welding or soldering. The junction box fulfils protection class IP65 and is suited for the use in salty air.


Fully NEC 2011 compliant requiring the special tool PV-MS-PLS to disconnect the cable The Westlake is a particularly flat-built box, which can be installed directly underneath the module frame. This eliminates the need to bend the connecting ribbons, saving valuable time in the installation process.


Papendorf Software Engineering GMBH


SOL.Connect Monitoring


PAPENDORF SOFTWARE ENGINEERING stands for Monitoring, Metering and Management of energy producing systems. Under the label SOL.Connect or as OEM parts they deliver products and services to many system providers and manufacturers of photovoltaics.


The SOL.Connect Center, collects data from inverters via RS485-, RS232- or LAN interfaces.


Additional measureands like e.g. directed irradiation, module temperature, feed of power into the public grid etc. are being collected with the external sensor module SOL.Connect MultiScan and SOL.
