Technology and R&D

Heliup has commissioned a 100 MW factory in France to produce lightweight solar panels for flat commercial and industrial (C&I) rooftops with limited load-bearing capacity, using ultra-thin glass technology.

Researchers in China have developed a new methodology to improve the performance of solar-powered air source heat pumps. The proposed approach reportedly increases the energy efficiency of optimized building systems by 18%, with solar energy potentially reducing their carbon content by 37.78%.

pv magazine is compiling a guide to home solar installations, aimed at those who are interested in installing but are new to the market and want to make an informed decision. We have spoken to associations, installers and industry specialists in major solar markets across the globe to compile best practice guidance and advice that aims to be applicable to home solar installations anywhere in the world. 

While sales of off-grid solar kits increased slightly in 2024, the market has not regained the momentum seen before 2022. The latest report from the industry’s professional association, Gogla, includes data for the first time on solar generators (38,000 units sold in 2024) and walk-in solar cold rooms (578 units).

Aurora Energy Research has rolled out Lumus, a contract valuation tool that helps energy market participants assess long-term risk in power purchase agreements (PPAs) across key parts of Europe.

The research group led by Professor Martin Green has published Version 66 of the solar cell efficiency tables. There are 17 new results reported in the new version.

Scientists in the United Kingdom have demonstrated the feasibility of residential ice-source heat pumps in cold climates and densely populated areas. They designed a heat pump system that utilizes existing gas pipelines to transport water.

The Defense Advanced Research Projects Agency said a project team testing new optical wireless energy receiver technology was able to transfer 800 W of power to a receiver 8.6 km away in a 30 second transmission. It claims is a distance and power record amongst optical power beaming demonstration results.

A research team based at Lawrence Berkeley National Laboratory says that solar could have the lowest levelized cost of energy (LCOE) of all energy sources in South Korea by the early to mid-2030s. 

The Fraunhofer Institute for Solar Energy Systems ISE (Fraunhofer ISE) has launched Diveo GmbH to plan and construct different kinds of agrivoltaic facilities without focusing on specific technologies.
