Hoymiles presented its latest product and technology innovations, led by its HMS microinverter and HAS hybrid inverter, at RE+ 2024 in Anaheim, California. The HMS series of microinverters ranges from 1,600 to 2,000 VA. Its 4-in-1 design integrates four input channels in one single unit, so fewer microinverters are need for the same capacity. The independent MPPTs deliver the optimal energy production of each PV module. The HAS-LV-USG1 AC-coupled inverter, when paired with HMS microinverters, can prepare the PV system for energy storage. The HAS inverter transforms excess AC power during the day into DC power and stores it in…
The Root-Power team consulted with AONB officials and local conservation groups before submitting the planning application in late 2023. Image: Root-Power. YLEM Energy arm Root-Power, which launched earlier this year, has been granted planning permission for a 12MW/48MWh battery energy storage site in Caterham, Surrey. The 4-hour Tillingdown Farm site, expected to go live in 2025, is located in both the green belt and the Surrey Hills Area of Outstanding Natural Beauty (AONB). As such, the development process was “exhaustive” and the Root-Power team consulted with AONB officials and local conservation groups before submitting the planning application in late 2023.…
Sharp’s new IEC61215 and IEC61730 certified solar panels have an operating temperature coefficient of -0.29% per C and a bifaciality factor of more than 80%. September 17, 2024 Emiliano Bellini The NBJG445R moduleImage: sharpSharp has unveiled new n-type monocrystalline bifacial solar panels based on tunnel oxide passivated contact (TOPCon) cell technology.The modules are equipped with 96 half-cut solar cells based on G12 wafers and a design with 16 busbars. They also feature an energy conversion efficiency of up to 22.52% and an output power of 430 to 450 W.“The bifacial NBJG445R and NBJG450R modules have a white coating on the…
An international research team has investigated how thermoelectric subcooling can be integrated into propane heat pumps to reduce energy consumption in the vapor compression system. Their work showed that this combination can not only reduce electricity consumption, but also significantly improve heat pump performance. September 17, 2024 Emiliano BelliniAn international research team has conducted a computational analysis on propane (R290) vapor compression heat pumps that integrate a thermoelectric subcooler (TESC) to reduce the energy consumption of vapor compression systems and found that this combination can increase the coefficient of performance of the heat pumps by 12.29% .In the newspaper “Effect…
German fluid management company Lutz-Jesco introduced a system aimed at supporting pumps and water disinfection in the event of a power outage. The hub is pre-configured to work with solar panels, a battery charge controller, an inverter and cabling.

Harnessing the Sun’s Power for Year-Round Cultivation In the ever-evolving world of agriculture and horticulture, the integration of renewable energy sources has become increasingly important. Among these innovations, the use of solar panels for greenhouse heating stands out as a game-changing solution. This approach not only addresses the energy-intensive nature of greenhouse operations but also aligns with the growing demand for sustainable farming practices. In this guide, we’ll explore using solar panels to heat greenhouses, examining the benefits, challenges, and best practices for implementation. Solar Energy and Greenhouse Heating Before diving into the specifics of solar-powered greenhouse heating, it’s crucial…
From pv magazine 24/09The residential solar industry is often called the “solar roller coaster” in the United States because it has seen peaks and valleys in customer demand, business profitability and investment.SunPower, one of the largest and oldest solar energy companies in the United States, has suffered its latest dip after announcing bankruptcy and delisting from the Nasdaq Stock Exchange. Once valued as worth billions of dollars, SunPower shares fell more than 99% from their all-time high valuation in 2007.The company provided homeowners with rooftop solar, energy storage and electric vehicle (EV) charging. It operated a dealer network in which…
Empact Technologies, a provider of IRA compliance management software and services, and Crux, the sustainable finance company, jointly announced a new partnership. The partnership allows Crux to connect project developers and tax credit buyers directly to Empact for tax credit compliance, and Empact to connect project developers to the Crux platform to monetize project tax credits. The IRA will provide an estimated $1.2 trillion in stimulus by 2032. The portability of federal clean energy tax credits has created a new market mechanism to finance clean energy projects, opening doors for both traditional players and buyers of non-traditional tax credits to…
The new solar cell uses tungsten sulfide as a field layer on the back surface. According to the makers, this layer can be incorporated into conventional CIGS solar cells to improve their efficiency and reduce the cost of the absorber material. September 17, 2024 Emiliano BelliniResearchers from Visvesvaraya National Institute of Technology in India have proposed a new copper-indium gallium diselenide (CIGS) solar cell structure using tungsten disulfide (WS2) as the back surface field (BSF) layer.BSF layers consist of a higher doped area at the back of the solar cell and are often used to increase the voltage of a…
The practical issue of taking apart a dead PV system and moving the components to their next destination has received less attention than recycling and second life applications. In the United States, Decom Solar offers dismantling for commercial and industrial (C&I) solar projects. pv magazine spoke to Decom Solar co-founder Stephen Burns for an update. September 17, 2024 Mark Hutchinspv magazine: Can you tell me something about Decom Solar and its work?Stephen Burns: Before I started Decom Solar, I worked in the solar energy sector for a project developer for 10 years. At that time, we started seeing clients requesting…
