The Coalition for Community Solar Access (CCSA) says that household names such as Microsoft, Google, Walmart, Starbucks, Rivian, Wendy’s, and T-Mobile are just a few of the Fortune 500 companies that have signed agreements with community solar developers.

Europe is witnessing a surge in power purchase agreements (PPAs). Over the past four years, the number of European PPA transactions has trebled. More than 180 deals were signed in 2022 alone and the trend is expected to continue, especially for solar projects.

With energy certification already a must-have for any business which makes green energy claims, Ed Everson, chief executive of England-based, global certification company Evident, makes the case for firms to be required to make full disclosure of their energy sources.

The rising popularity of “baseload” power purchase agreements (PPAs) has posed questions to solar electricity suppliers in the German market. How can projects that do not generate at night, and with wide seasonal output variation, effectively supply constant power to consumers? More importantly, who shoulders the price risk?

Scientists in the United States developed a computer simulator that can calculate the conversion efficiency of different solar cell materials and configurations – helping to guide research and optimization of new cell designs. The simulator is available to researchers as an open-source tool to save time and spot the best opportunities for optimization of any given approach.

Re-Source 2021 took place in Amsterdam at the end of last week, and pv magazine was there to cover the event where the suppliers and sellers of renewable power purchase agreements (PPAs) meet the (largely corporate) buyers, though encouraging PPA uptake among small and medium-sized enterprises (SMEs) was among the major talking points, including ‘additionality’, de-risking renewable PPAs and 24/7 matching.

Corporate renewable energy purchases are at an all time high. In Europe alone, a record-breaking 4 GW of corporate power purchase agreements were signed in 2020, bringing the overall total to 15 GW. Globally, this figure is even higher. As part of the UP Initiative’s quarterly theme on ‘Sustainable electricity and corporates’ critical solar role’, pv magazine spoke to Hannah Hunt, Impact Director at RE-Source, a European alliance of stakeholders representing clean energy buyers and suppliers, about how the business model landscape for such purchases is evolving, and the challenges the sector faces, including shortages in renewable energy supply across Europe.

The oversubscribed fund was closed with the help of a commitment by Austria’s national development bank. U.S. and Swedish state-owned lenders and impact investors dominate the pool of contributors to the debt finance, which will fund small-scale installations.

The SunPower solar monitoring app draws inspiration for its user interface from unlikely non-energy sources such as Spider-Man.

The Solar Mapper uses artificial intelligence algorithms that compile data extracted from satellite images. It can estimate site solar potential and indicate the most suitable technology.
