In a new weekly update for pv magazine, Solcast, a DNV company, explains that the solar cycle does tend to increase the earth’s average annual extra-terrestrial irradiance, but only by a very small amount. It also explains that, while the annual cycle of extra-terrestrial irradiance causes a steady, predictable and significant 3.5% change through the seasonal cycle, the peak of the 11-year cycle of solar activity causes a smaller, more sporadic and unpredictable set of fluctuations.

This week, Women in Solar Europe (WiSEu) gives voice to Oana Ijdelea, the founder and managing partner of Romanian law firm Ijdelea & Associates. She says there is no objective blockage impeding women from pursuing a career in the renewable sector. There is, however, a vicious circle where women may become reluctant to apply for a position where males appear to be more present, and on the other hand, the lack of female presence in such roles does not encourage other women to step in.

Swiss consulting firm Pexapark says the total capacity of signed power purchase agreements (PPA) in Europe in April more than doubled the volume it recorded in March. Meanwhile, all tracked PPA prices rose 1.6% month on month.

To assess renewable energy, particularly solar and wind, considering the limited supply of input materials, researchers from Shenzhen University established novel hybrid multi-criteria decision-making (MCDM) models that include a circular economy principles, waste potential and life cycle assessment (LCA).

The Eurasian Development Bank has agreed to provide $210 million over 15 years for Bishkek Solar to build a 300 MW solar plant in Kyrgyzstan. National Electric Grid of Kyrgyzstan will purchase the electricity for a period of 25 years.

Companies interested in a new engineering, procurement and construction (EPC) contract for a 15 MW ground-mounted solar plant in western Uganda must request prequalification questionnaires from TotalEnergies Uganda by June 7.

JMK Research projects that 21.2 GW of new solar capacity will be installed in India in fiscal 2025. The new additions will include 16.5 GW of utility-scale PV, 4 GW of rooftop solar, and 700 MW of off-grid installations.

Scientists in South Africa have modeled a photovoltaic system connected to a thermoelectric cooling device and have found it may produce around 9.2% more electricity than conventional PV system without cooling. The research team claims the proposed system guarantees a minimum cost saving of 10.56%.

A Chinese research group including scientists from module maker Tongwei has designed a perovskite solar cell with remarkable perovskite film quality through the so-called self-disintegrating seed strategy. The device not only achieved one of the highest fill factor values ever recorded for perovskite solar to date, but also showed remarkable stability.

Researchers in Nigeria have proposed to build inverted perovskite solar cells exclusively with all-inorganic transport materials and a lead-free perovksite absorber. Through a series of simulations, they showed these device may achieve efficiencies over 30% with low production costs.

U.S. scientists have developed a thermophotovoltaic cell that could be paired with inexpensive thermal storage to provide power on demand. The indium gallium arsenide (InGaAs) thermophotovoltaic cell absorbs most of the in-band radiation to generate electricity, while serving as a nearly perfect mirror.

The versatility of solar mounting manufacturer and balance-of-system provider Clenergy’s ezShade 2.0 solar shade system has been put to the test with the solution at the core of a standalone power system fuelling an off-grid communications site in remote northern Queensland.

Perovskite PV devices are set to become the next big thing in solar with market analysts at S&P Global Commodity Insights predicting 1 GW of production by the end of 2024, rising to 6 GW in 2025. Perovskite tandem devices are at the front of the queue for commercialization but their characterization presents technical challenges.

Developer Loop Energia has built a 1.2 MW offgrid solar plant that now serves a center-pivot irrigation system in the Brazilian state of Bahia. The project reportedly enables local farmers to double soybean harvesting by achieving considerable savings through significantly lower diesel consumption.

Visionpark said its novel solar carport solution is self-weighted and requires no foundation. It can reportedly host all kinds of solar panels and be installed quickly.

The European Solar Manufacturing Council (ESMC) has voiced support for the inclusion of non-price criteria in auctions for solar modules, as laid out in the EU Net Zero Industry Act. The council’s recommendation paper also calls for member states to adopt the act as quickly as possible and highlights concern around cybersecurity and data security in relation to Chinese inverters.

Aiko Solar has won a patent litigation case against Maxeon Solar Technologies in a Dutch court. The judge has ruled that Aiko Solar did not infringe upon Maxeon Solar’s EP2297788B1 patent for back-contact (BC) solar cells.

Nikola plans to sell 100 hydrogen fuel-cell trucks for logistic operations in California, Volvo has started developing hydrogen combustion trucks, and Airbus has announced plans to launch a study into hydrogen projects in the US state of Georgia.

BloombergNEF (BNEF) says in a new study of 1,600 planned hydrogen projects that governments will miss their 2030 hydrogen targets. Analyst Adithya Bhashyam tells pv magazine that most of the announced projects to the end of this decade lack the key conditions for success.
