AESOLAR groups up with Fraunhofer CSP for shade-resistant PV module analysis – pv journal Worldwide

Renewable vitality targets in Europe require important will increase in renewable vitality deployment. Rooftop installations have dominated different purposes in Europe, with about 60% of the market share in 2022. Germany is the most important market within the area with respect to complete set up capability, with over 42 GW of PV on rooftops by the top of 2021. The Netherlands, because the nation with highest set up capability per capita in Europe, has over 80% of the installations on small rooftops. Such knowledge exhibits the significance of the Rooftop phase in PV market.

One of many greatest challenges for rooftop PV modules is partial shading resulting from obstacles similar to bushes, chimneys, or parapets. Close by constructions, mud and snow are additionally a frequent contributor to the problem. Partial shading results in a major energy loss in module degree, and it results in mismatches on the module degree in addition to between modules related in a string. The facility loss resulting from partial shading is very depending on the module design, shading sample, and shading orientation.  Whereas energy optimizers can optimize the losses from mismatch, they can not save the affected string or PV module and so they enhance the funding quantity.  Moreover, energetic digital units are proven to have a decrease lifetime in comparison with passive elements like PV modules.

To beat the shading challenges of rooftop modules, AESOLAR developed a shade-resistant PV module with built-in bypass diodes for every particular person photo voltaic cell. The module can produce as much as 80% extra vitality than conventional modules beneath partial shading situations. The AESOLAR module makes use of full-size photo voltaic cells for the design and is unbiased from shading orientation. The module has acquired the prime innovation award from pv journal in 2018.

To additional develop this know-how, AESOLAR is collaborating with Fraunhofer Middle for Silicon Photovoltaics (CSP) to develop a brand new technology of shade-resistant PV modules utilizing half-cut cells. The collaboration is being carried out beneath a SegmentPV analysis undertaking and is funded by Germany’s Federal Ministry of Financial Affairs and Local weather Motion (Bundesministerium für Wirtschaft und Klimaschutz). The undertaking began in Could 2023 and entails two years of analysis work. “Inside the undertaking, module elements, designs, and prototypes created by AESOLAR will probably be examined by Fraunhofer CSP to attain a better vitality yield, higher shading tolerance, and very good reliability for an progressive product that tackles one of many greatest challenges of rooftop PV,” says Dr. Hamed Hanifi, Director of Analysis and Improvement at AE Photo voltaic and coordinator of the SegmentPV undertaking.
