How to operate PV-driven residential heat pumps under time-varying tariffs
Researchers in the United Kingdom developed a scheduling model for residential heat pumps that reduces electricity costs while maintaining thermal comfort under dynamic tariffs and uncertain rooftop PV generation. It optimizes when to use grid power, PV energy, and building thermal storage.
Cyber threats for PV: What are cloud platform and software-as-a-service exploitation attacks and how do they work
Cloud and SaaS platforms are now central to PV plant operations, but their centralization creates a high-impact cybersecurity risk where a single compromise can expose or disrupt entire fleets of installations. Attackers exploit weaknesses like stolen credentials, insecure APIs, multi-tenant flaws, and platform vulnerabilities, making strong identity controls, secure APIs, and continuous monitoring essential defenses.
Low-pressure hydrogen bridges seasonal gaps in solar-powered Japanese building
Taisei Corporation has demonstrated that a building can operate entirely on solar power by combining PV generation with a hybrid storage system integrating batteries and low-pressure hydrogen at a test facility in Yokohama. An EMS-enabled setup using lithium-ion batteries and PEM electrolysis balanced short- and long-term energy supply and demand, enabling year-round renewable operation, according to the company.
