via an efficient constant-voltage power bus. This approach allows the connection of an unprecedented number of panels on a single cable - more than 100 panels can be linked on a single run, a twenty- fold improvement over conventional string architecture.
This results in extensive installed-cost savings. The amount of cable needed is reduced by 2 to 5x, and the numberof combiner boxes and the person-hours of installation labor can be reduced by up to 20x. For a hypothetical 1 megawatt installation, these factors combine to a savings of over $400,000 in balance-of-system costs. In addition, vBoost also provides per-panel MPPT, and eliminates energy- sapping interactions between panels on the same string. This increases energy harvest by 5% to 30%, and greatly simplifies the job of the array designer.

Canadian Solar NewEdge modules
Canadian Solar’s NewEdge panels with Zep Compatible frames offer the solar industry’s fastest and most cost effective way to install photovoltaic (PV) solar systems on residential roofs.
The NewEdge panels are the first of their kind to be fitted with a special “Zep Groove” on the frame to fit quickly and easily with Zep Solar’s breakthrough rail-free, auto-grounding system as well as several other existing mounting systems.
Coupled with NewEdge modules, the Zep System II cuts residential installation costs in half and reduces the amount of
The Xcell X2 is the next generation of our firmly rooted Xcell solar cell interconnection platform. It is capable of interconnecting solar cells for 25MW per year on 11m2 of floor space. The driving forces behind this evolutionary machine are our customers’ ambitions to reach grid parity. Utilizing one machine base for two string tracks in combination with just one solar cell handling robot, allowed building one of the most compact solar cell interconnection machines ever seen. This simple concept enables us to offer a high-end machine for an extremely attractive value.
The Xcell X2 is equipped with numerous new features. Solar cell handling is reduced to just one pick and place before pre-heating (single robot approach) and all sequencing motions are servo controlled, which has the benefit of total speed, acceleration and deceleration control. Building on our proven spray fluxing method, the enhanced version even allows for spot application. Z-Bend ribbon handling is part of the standard package and can simply be turned on or off over the
time installers spend on a roof by up to 75 percent. NewEdge modules lead in PV USA (or PTC) ratings, which are quickly becoming universally, accepted standards for real-world module power and performance — more closely simulating real-world solar and climatic conditions than Standard Test Condition (STC) ratings.
According to California Energy Commission (CEC) listing data, they rank amongst the industries highest per Watt PTC among key module manufacturers with mainstream P-type silicon technology.

HMI. The Komax Solar Xcell X2 uses the industry leading induction soldering technology. Further enhancements in the process allow us to achieve breakage rates as low as 0.3% for 160 µm thin solar cells. Technical improvements are important, but operating the machine is a key point as well. Therefore easy to open gull wing doors allow convenient machine access and newly positioned ribbon-loading points, as well as an all- together lower machine base, provide improved ergonomics.
A modern GUI (Graphical User Interface) layout with highly intuitive screens is part of the machine, as well as SCADA, which collects data about material, solder recipes and machine performance. Naturally, the machine is designed to operate perfectly with Komax Solar’s latest generation of String to Glass Lay- Up as well as with the XM 50 (50MW) to XM 250 (250MW) expandable Matrix Assembly System line.
