Panasonic HIT solar module achieves world’s best output temperature coefficient

Panasonic Corporation has achieved the world’s leading output temperature coefficient for mass-produced silicon photovoltaic modules, at -0.258%/°C. This record-breaking innovation sets a new standard for the solar industry, improving on the previous temperature coefficient by 0.032 points at the mass production level, highlighting the positive temperature characteristics of heterojunction solar cells and further improving Panasonic’s

Solaria provides traditional PV modules and BIPV for new Cornell Tech campus building

Solaria has provided 2,300 PowerXT and customized PowerView modules to buildings on Cornell Tech’s innovative new campus on Roosevelt Island in New York City. Combined, the Bloomberg Center (designed by mOrphosis Architects) and the Bridge building (designed by WEISS/MANFREDI Architecture/Urbanism/Landscape) has a 900-kW system, part of a strategy to generate all of the power needed

Ohio 4-MW solar landfill project to use mostly Ohio-made solar products

Cuyahoga County, Ohio, has reached an agreement to utilize Ohio made solar panels and racking systems in the landfill solar project it is helping to develop in Brooklyn, Ohio. Cuyahoga Urban Renewable Power (CURP) is developing the 4-MW solar project located on a former landfill in the City of Brooklyn, Ohio, near Cleveland. As the

Bifacial solar panels: Breaking the barriers of module efficiency

As solar technology has improved over the last decade, the prices have dropped exponentially as module efficiency has advanced. In recent years, there’s been a growing concern that we are approaching an efficiency ceiling. People have come to wonder if future solar improvements will be through system solutions, such as coupling solar with storage, rather

GCL-SI reaches 20.6% efficiency in multi-crystalline PERC solar cells

GCL System Integration Technology recently announced that it has raised its self-developed Passivated Emitter Rear Cell (PERC) solar cell average efficiency to 20.1% in mass production by utilizing Reactive Ion Etching (RIE) technology, with the highest test reaching 20.6%. It marks a major step forward in advancing the efficiency of multi-crystalline cells. Black silicon is

Solar Basics: Canopy-side solar chat with Eaton

Solar Basics is a video series by Solar Power World created to help installers learn about the business, tools and tricks of the solar power trade. Solar Power World visited Eaton’s Power Systems Experience Center to learn more about the company’s role in solar and storage. Editor Kathie Zipp speaks with Eaton’s John Vernacchia in

Trending in solar panels: Drop in global demand narrowing playing field

The last year has been tough for the solar panel manufacturing worker. Almost every major module manufacturer experienced layoffs of some kind, all chalked up to “restructuring” after a slowdown of global demand. A glut of projects made 2016 an explosive year for the United States, nearly doubling the previous year’s installations. The same massive

SunPower partners with Solect and Green Street to install 6.9 MW at Massachusetts schools, colleges

Ranked seventh among U.S. states for the most solar capacity, Massachusetts is adding 6.9 MW to its 1,487 MW of solar currently installed and operating. Solect Energy and Green Street – members of SunPower’s reputable national dealer network – have developed two high-efficiency SunPower solar systems that will provide electricity to 10 Massachusetts schools. In Easton

Trending in solar panels: PERC, new cell designs diversifying competitive market

While 60-cell panels are still dominant, it appears more powerful 72-cell designs are being used, according to Solar Media Ltd. This can mostly be attributed to more 72-cell panels being used in utility-scale solar—the largest solar market—as these projects are looking for the highest output. Some of the most cost-efficient ways to reach even higher

What causes solar panel degradation?

Although crystalline solar panels are often sold with 25- to 30-year lifespan guarantees, those 30-year-old modules won’t be performing as well as they did on Day 1. Performance declines as solar cells degrade due to unavoidable circumstances like UV exposure and weather cycles. Manufacturers realize this, so solar panels come with a power output or
