Panasonic solar module posts world-leading output temperature coefficient

Panasonic Corp. says it 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 unique heterojunction technology.

Temperature coefficient explained

Output temperature coefficient is a vital metric in evaluating solar modules as a measurement of how quickly their conversion efficiency degrades as the temperature rises, thereby reducing the output. The standard silicon solar cell’s output temperature coefficient is -0.50 percent, which denotes a decline of 0.50% in the conversion efficiency as the module temperature rises by 1° C. For instance, at the module temperature anticipated in the summer months (75° C), the conversion efficiency will decrease by 25% in comparison to the environment at 25°C.

Panasonic HIT modules, which boast an improved output temperature coefficient, will nearly halve the decline in the conversion efficiency, significantly increasing performance in high temperature settings.

Why high-efficiency modules are the best value for installers, homeowners

The combination of the high conversion efficiency with the new temperature characteristics, will increase the conversion efficiency at 75°C by 46 percent in comparison to standard silicon products. When most solar panels are struggling with the increased temperatures during the summer months, Panasonic HIT modules reliably generate power and limit efficiency losses in the heat. Not only that, Panasonic modules come with a 25 year warranty vs the industry standard of 10 year warranty, and guarantees output of 90.76% at the end of the 25th year, which in itself is industry’s best performance guarantee coming from a 100-year-old world leading electronics company.

Solaria BIPV technology now available through CleanFund Commercial PACE financing

Solaria BIPV

Builiding Integrated Photovoltaics (BIPV) just got a little more affordable. CleanFund Commercial PACE Capital, formed a financing partnership with Solaria Corp. to offer long-term financing for its building skin technology. By providing commercial building owners access to Solaria’s customizable product line, along with the benefits and flexibility of C-PACE financing, this SolarPACE collaboration maximizes the availability of long-term incentives to developers who implement architectural solar  into commercial projects.

SolarPACE explained

SolarPACE is designed to maximize cash flow, with terms up to 30 years. It can solve most credit challenges found in commercial solar project financing, since C-PACE is secured by a parcel tax assessment with payments billed through ordinary property taxes. Owners often have the option to pass all or a portion of the C-PACE payments to tenants, who also benefit from lower energy costs. With flexible options to utilize solar tax credits, SolarPACE enables build-ing owners and developers to stay within project budgets and lower overall project costs.

“Solaria is privileged to partner with the leading provider of a nationwide financing platform that makes building improvements affordable for commercial property owners,” said Udi Paret, GM Building Solutions, Solaria Corporation. “Now we can offer customers a viable option for funding and installing an architectural solar system, especially important for net zero energy projects. This is a significant competitive advantage for our industry partners who offer their own warran-tied ‘powered-by-Solaria’ architectural solar products.”

Silicor Materials reports on its first p-type mono PERC production results

silicor materials

Silicor Materials, Inc., says that, in its first ever attempt, the company has produced p-type mono PERC (Passivated Emitter Rear Cell) cells at approximately 20 percent efficiency, using 100 percent of its standard silicon feedstock.

“We are extremely pleased with the results of this first attempt at mono cell production,” says Alain Turenne, Chief Technical Officer at Silicor Materials. “These results show the power of our process to produce silicon of such high quality that even the demands of a mono PERC cell architecture are well within reach.”

A small mono boule was expertly grown and wafered at Fraunhofer CSP’s lab for crystallization technology in Germany, and then converted into cells by a manufacturing partner. The result demonstrates that Silicor’s low cost, high quality feedstock can be used to make mono-crystals using the Czochralski method, as well as high efficiency monocrystalline solar cells. These results further confirm that Silicor’s breakthrough technology for manufacturing solar grade silicon provides the solar market with a simple solution to manufacturing the highest quality, highest efficiency solar cells of the future at a substantially lower cost than all other solar grade silicon manufacturing technologies on the market today.

“These results come at no surprise to the Silicor team but will to some of our competitors, who have become wedded to very expensive methods to manufacture solar grade silicon,” said Terry Jester, CEO of Silicor Materials. “Our results with mono PERC cells are only the beginning. We will continue our work with perfecting the manner in which our material is integrated into mono wafer manufacturing and expect even better results in the future. Silicor Materials has significant experience in using its material in multi-crystalline applications and has a track record of continuous improvement in cell efficiency. This news is certain to be welcomed by customers and investors alike.”

Sungage, Sunnova add Seraphim Solar USA modules to approved product lists

U.S.-based solar photovoltaic module manufacturer Seraphim Solar USA says its high-efficiency, American-made solar modules have been approved by major residential solar finance companies for their installer networks. Sungage Financial and Sunnova are among the finance firms that have added Seraphim USA to their approved vendor lists, citing the manufacturer’s bankability, product quality, and reliability. As a result, installers across the country can now offer Seraphim USA modules to their customers as part of their home solar financing packages.

The news comes as Seraphim USA accelerates its production ramp at the company’s fully automated, state-of-the-art PV module manufacturing factory in Jackson, Mississippi. One of the largest facilities of its kind in the U.S., the 160 MW facility is producing 60- and 72-cell polycrystalline and monocrystalline silicon modules for residential, commercial, industrial, governmental and military customers in the United States.

“Thanks to the confidence our finance partners and our customers have in our products, we’ve seen our order intake grow — we’re shipping our modules as fast as we can make them and are actively hiring production staff,” said Steve Ostrenga, vice president of sales for Seraphim Solar USA. “With uncertainty clouding some parts of the U.S. solar manufacturing community, developers and installers who want top-quality, U.S.-made products are looking to us as a reliable and bankable supplier.”
