JinkoSolar (U.S.) Inc., in partnership with the Solar Energy Industries Association (SEIA) and a coalition of other solar companies, is launching the nation’s first PV recycling program, which includes a network of cost-effective recyclers that can responsibly dispose of decommissioned PV modules.
While JinkoSolar modules are expected to last at least 25 years, PV system owners now have dedicated resources to help aid in responsible disposal of modules once they reach the end of their life cycle. JinkoSolar modules recently passed toxicity characteristic leaching procedure (TCLP) tests. Products that do not leach toxic materials at levels exceeding regulatory limits are termed TCLP compliant. TCLP compliant JinkoSolar modules will give system owners more time and flexibility to dispose of the modules.
“JinkoSolar has always been keen to ensure that its modules are clean and eco-friendly from cradle to grave,” said Nigel Cockroft, General Manager of JinkoSolar (U.S.) Inc. “By passing TCLP tests and helping start this recycling framework, JinkoSolar has shown that it is a true leader in environmental responsibility.”
Seen at Solar Power International this year: Mission Solar Energy, a San Antonio-based manufacturer of utility-scale, commercial and residential high-efficiency solar modules, added four new module lines to its product offering. The Apollo, Mercury, Gemini and Gemini Elite modules utilize advanced technology to provide best-in-class efficiency, reliability, power and aesthetics.

By integrating the microinverter and eliminating the need to install a centralized string inverter, the SolarWorld AC Module can speed installations and simplify logistics, increase safety during installation and operation and offer module-level optimization. The company developed the new AC module in concert with Enphase Energy Inc.
Silfab Solar (booth 2373) will debut one of its most advanced 60-cell solar modules with a maximum power rating of 300Wp. The Silfab 300Wp modules are ideal for ground-mount and rooftop installations where space constraints and architectural designs are a factor. Silfab’s unique designs and manufacturing techniques result in modules that have fewer components for faster installation and improved system balance, maximum and sustained power performance lasting for decades after installation, aesthetic designs and more.
SolarWorld, one of the largest crystalline-silicon solar manufacturers in the Americas, exhibited a new 72-cell XL product at Intersolar North America. This new 1,500-volt solar panel will be ready in time for this year’s fourth-quarter peak selling season.
The 1,500-volt technology, compared with standard 1,000-volt solar panels, enables installers to increase lengths of solar-panel strings by up to 50 percent, thereby requiring fewer combiner boxes, less wiring and trenching and lower labor costs. Analysts have estimated the cost savings at up to 5 cents per watt installed.
The technology’s application is ideal for large commercial and utility-scale designs. SolarWorld has not needed to increase the size of its 72-cell solar panel to reach the 1,500-volt standard. The new solar panel is certified to UL1703; it is free of potential induced degradation (PID), as per IEC 62804-1:2015.
“SolarWorld does whatever it can to help its installation partners lower their costs and increase profits,” said Mukesh Dulani, U.S. president of SolarWorld. “This new product maximizes the benefits of our 72-cell solar panel design without having to alter its size. It represents just the latest development in our long track record of achieving innovations that serve the market. Our customers want this option, so therefore we are bringing it to market.”
The company is taking orders for the 1,500-volt module for delivery starting in October.
LG Electronics announced its upcoming push into the commercial and utility-scale space at Intersolar with the launch of its flagship NeON 2 in a 72-cell solar panel.
Why might these be a good option for your next C&I project? LG’s N-Type double-sided cell structure allows the panels to produce more energy with a smaller footprint (they reflect light from the rear of the module to be reabsorbed). This newest model features a series of 72-cell modules that make it easier to manage space when installing a large-scale system without sacrificing energy output. The three models, LG365N2W-G4, LG370N2W-G4 and LG375N2W-G4, are designed to deliver outputs ranging from 365 to 375 watts, in a 6.41- by 3.28-foot panel, thereby producing more power in less space.
“LG’s NeON 2 72-cell panels are the perfect solution for commercial and utility scale installation projects looking for a highly efficient solar energy solution without compromising their roof or green space,” said David Chang, U.S. head of sales for LG Solar. “These panels combine LG’s signature sleek design with the newest technology on the market to provide businesses an attainable solar solution for long-term cost savings.”
Advancing the success of LG’s flagship NeON 2, the N-Type material was developed through an elaborate process control, adopting a semiconductor processing solution, which boasts higher mobility of electric charge. As a result of their improved temperature coefficient, the NeON 2 72-cell panels can generate more electricity on sunny days and even performs more efficiently on cloudy days, allowing one module to generate more energy per square foot, regardless of environmental factors.
LG’s flagship NeON 2 and NeON 2 Black solar panels feature LG’s innovative Cello technology, which utilizes circular-shaped wires to scatter light for better absorption while reducing the electrical loss and increasing power output and reliability by spreading the current with 12 thin wires rather than the traditional three busbars
While the new NeON 2 72-cell is optimized for commercial use, the new NeON 2 and NeON 2 Black solar panels are ideal for residential applications. The NeON 2 Black features an all-black design, which makes it almost undetectable against a roof for a sleek appearance. The 320W NeON 2 delivers a 6.4 kWp capacity with 20 modules (60 cells) compared with competing 285W p-type Mono panels with the same number of modules that generate only 5.7 kWp.
Unlike conventional p-type solar modules, the N-Type cells used in the NeON 2 72-cell, NeON 2 and NeON 2 Black use almost no boron, so Light Induced Degradation is reduced significantly. The improved 72-cell module reduces annual degradation from -0.7 percent to -0.6 percent per year, allowing LG to extend the warranty to a full 12 years.
