Researchers in Canada designed an air-source heat pump integrated with an air-based solar collector and radiant floor heating for cold climates, showing that the proposed system configuration could improve the coefficient of performance from 2–4 to 2–6 and reduce significantly annual energy consumption.

Grid operator PJM has reopened its standard interconnection process to new generation projects, after closing the standard process to new applicants in 2022 to completely clear its backlog.

The announcement of the company’s latest module power electronics project came alongside Q1 2026 earnings that showed a 20.6% decrease in year-over-year revenue numbers amid a steep decline in domestic demand.

Artificial intelligence came through at a crunch time for SESA-PR President PJ Wilson. The veteran solar advocate makes the case in an interview for solar and storage policy advocates to make good use of AI resources.

The agreement aims to bypass terrestrial grid constraints by beaming near-infared light from space to terrestrial solar plants to power high-density AI workloads.

Human activities in space have been solar powered for more than 70 years. Now, as the space industry accelerates, new opportunities are emerging for specialized solar manufacturers, writes Jake Veloza of Eternal Sun Wavelabs. The extreme and unforgiving conditions of space demand a high level of performance and durability, and accurate testing methods will be needed to get these new solutions off the ground.

U.S. scientists have developed a method to forecast solar irradiance at any location using a single high-resolution hemispherical image captured on-site. By extracting sky, sun, and surrounding scene information from visual cues, the approach enables accurate long-term energy prediction without relying on detailed 3D city models.

Solx’s Aurora hybrid module with Caelux’s perovskite glass aims to compete on performance beyond federal tax sunsets.

Researchers in the United States reviewed claims about PFAS in solar panels and found that while fluoropolymers may be used in limited components like backsheets or coatings, there is no confirmed evidence of PFAS leaching from commercially deployed modules. The study highlights widespread confusion between different PFAS types and emphasizes the need for clearer communication and transparency around fluoropolymer use in PV technologies.

The International Energy Agency’s latest Global Energy Review shows solar PV accounted for 27% of all energy demand growth, while demand grew 62% faster in the U.S. than the world total, largely driven by a 10% increase in coal use, as the world enters what the report’s authors call the “Age of Electricity.”
