Modules & Upstream Manufacturing

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

Scientists in Europe have put together a comprehensive guide to PV module degradation, examining literature and case studies on the topic as far back as the 1990s. Their paper details the primary stress factors faced by modules in the field, the most common modes of degradation and failure, and provides clear definitions relevant to reliability, quality and testing standards. Among their key findings is that a full understanding of how combinations of different stresses over varying timeframes is still missing from methods to estimate and improve system reliability.

SolarPower Europe’s new guidelines for agrivoltaics are designed to support project developers, scientific institutions, and policymakers in developing agrivoltaic schemes. The PV trade body presents business cases from different European countries and shares best practices for O&M and engineering, procurement, and construction (EPC).

A new study details how floating photovoltaics impact wind flow and irradiance on lakes, with the effect of influencing water temperature at different depths. However, the report’s authors say more research is needed on how to design systems for maximum benefit to the water bodies themselves.

Xavier Daval, the president of Syndicat des énergies renouvelables (SER), the French renewables association – spoke with pv magazine at Intersolar 2023 about solar and nuclear power in France, as well as the prospects for PV prices and installations. He touched on the market for power purchase agreements (PPA) and the outlook for solar manufacturing in France, where PV installations could hit 3 GW this year.

Researchers in Japan have developed a repair technique for solar modules with damaged busbars and solder ribbons. They claim the new method can be implemented on site, without removing the panels from the array.

Solar’s levelized cost of electricity will reach $30/MWh in 2050, as global capacity surges, said DNV.

Scientists in France tested the effectiveness of various encapsulant materials, used to laminate solar cells into modules, at protecting cells and other components from damage caused by ultraviolet (UV) light. Their findings show that encapsulants with additives specifically designed to absorb UV light tend to turn yellow over time, which can contribute to various other problems with performance.

The research group led by Professor Martin Green has published Version 62 of the solar cell efficiency tables. There are 21 new results reported in the new version, a record number for the Tables.

In the second interview of a series held at Intersolar 2023, pv magazine spoke with Karen Tang, Director – Editorial Lead Europe at Singapore-based market research company OPIS, about current price trends in the industry. She said solar panels may soon be bought at an average of $0.185/W but she also revealed that offers under $0.15/W are now becoming more frequent. Furthermore, Tang said prices may continue to drop in the future, with the bottom line being difficult to determine. Much will depend on the actual manufacturing capacity we will see coming online, which may not match the huge number of recent announcements released by module producers.
