The proposed system, devised by a Dutch research group, aims to store excess renewable electricity through hydrogen generation and battery storage, with the latter only used when hydrogen generation is not immediately available. Despite the high initial cost, the system can reportedly provide stable operation. May 21, 2024 Emiliano BelliniResearchers from Hanze University of Applied Sciences Groningen in the Netherlands have investigated for the first time how hydrogen production and battery storage can be combined with PV energy on roofs or small wind turbines in off-grid households.“To our knowledge, no published study has used the hydrogen system as the primary…
Daewoo’s new hybrid inverters are equipped with LiFePO4 batteries. They are available in six variants, with capacities ranging from 0.5 kVA to 10 kVA. May 21, 2024 Uma Gupta By pv magazine IndiaSouth Korea’s Daewoo has developed new lithium battery inverters for solar projects. The hybrid inverters are available with a nominal output power of 0.5 kVA to 10 kVA. The built-in LiFePO4 lithium batteries eliminate the risk of acid leakage.The 1 kVA and 2 kVA inverters have a compact, portable design. According to the company, they can be wall-mounted or used outdoors as reliable power banks.The inverters can handle…
Ascent Solar secures order for thin-film PV from satellite manufacturer Ascent Solar Technologies, (Nasdaq: ASTI), an American innovator in the design and manufacturing of flexible, sustainable CIGS thin-film photovoltaic (PV) solutions, has received an order from a mega-constellation satellite manufacturer for the first delivery of PV modules for evaluation. The Ascent product will be evaluated for use in the manufacturer’s next generation hardware. Following delivery and successful completion of the in-space technology assessment for use in Low Earth Orbit (LEO), Ascent plans to work with the customer to design and manufacture Plug and Fly arrays for delivery as early as…
Researchers in China have outlined a new surface engineering strategy to build cheap solar cells without a hole transport layer. The devices were treated with benzoylcholine halide to reduce non-radiative recombination and achieved remarkable efficiency and stability. May 21, 2024 Emiliano BelliniA group of scientists led by Beihang University in China has developed a carbon-based all-inorganic perovskite solar cell without the use of an expensive hole transport layer (HTL).In the proposed cell architecture, the absence of the HTL, which prevents direct contact between the carbon electrode and the perovskite, is compensated by engineering the surface composition of the perovskite film.…

The Commodity Futures Trading Commission is investigating greenwashing as part of its crackdown on fraud and misconduct in voluntary carbon markets, a commissioner at the US regulator said on Monday. The investigation into false claims about the environmental benefits of carbon credits, as well as the green credibility of financial products, comes as the CFTC releases its first set of federal guidance on voluntary carbon…
To help owners and residents of affordable multifamily properties in Connecticut more easily access the benefits of solar energy and battery storage, the Connecticut Green Bank announced that its Solar Marketplace Assistance Program (Solar MAP) is now available for affordable homes with five or more units . This improvement was made possible by the passage of legislation in 2021, which expanded the definition of a residential customer for purposes of solar energy generation to include multifamily properties. Solar MAP for affordable multi-family housing is officially launched with an informative webinar presentation Thursday June 6 at 9:00 am. Through Solar MAP,…
Exploring Renewable Energy Frontiers – Hydro v.s. Solar: As renewable energy moves forward in progress, we’re delving into two fascinating methods: hydro-electric sources and solar panels. These technologies harness the natural energy of the earth in unique ways, offering sustainable alternatives to traditional power sources. Despite their differences, both hydro-electricity and solar power play crucial roles in our quest for cleaner, more efficient energy solutions. Let’s dive in and uncover the secrets behind their power. The Surge of Hydro-Electric Power Let’s uncover the story of hydro-electricity from its ancient origins to its modern-day mastery. We’ll explore how this technology has…
The Institute for Essential Services Reform (IESR), a Jakarta-based think tank, advocates the implementation of power wheeling in Indonesia. It says it would create a market for renewable energy and have a positive impact on industrial investment. May 20, 2024 Patrick Jowett Image: James Tiono, UnsplashAccording to Jakarta-based think tank IESR, the introduction of power wheeling in Indonesia would help accelerate the country’s energy transition to net zero emissions.Power wheeling, which refers to transporting energy from an electricity grid to an electrical load outside the grid boundaries, would allow electricity producers in Indonesia to supply electricity directly to end users…
Slovak scientists have developed a new hydrophobic, anti-reflective coating for solar glass with a thin film of silica-titanium oxide as the bottom layer and an inorganic-organic top layer made of silica modified with triethoxy(octyl)silane. This new coating increases glass permeability by 7% compared to uncoated glass. May 20, 2024 Lior KahanaA European group of scientists has developed a new hydrophobic anti-reflective (AR) coating for the cover glass of PV modules.The double-layer coating uses a thin film of silica-titanium oxide (SiO2-TiO2) as the bottom layer and an inorganic-organic top layer of silica modified with triethoxy(octyl)silane (OTES) as the top layer.”In this…
The solar industry often talks about ways to cut the soft costs of running a business — the behind-the-scenes project management software, training processes and data analytics that keep projects on schedule and up to quality. But one EPC says now is instead the time for investment into these areas to meet IRA requirements and give project owners peace of mind. Radiance Solar is based in Georgia, but works on distributed generation and C&I projects across the country. In this edition of our Contractor’s Corner series, we talk to CEO Steve Newby about the company’s commitment to using data to…
