The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will report the absolute record efficiency for all-perovskite tandems with two connections, regardless of the number of intersections. May 3, 2024 Emiliano Bellini The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) has updated its data Best Research Cell Efficiency Chart with the addition of a new cell category: hybrid tandems.“Record tandem cells with layers composed of two different PV materials have been collected in this category. Some subcategories of hybrid tandems (Perovskite/Si and Perovskite/CIGS) were already present in the previous format under ‘Emerging PV’,…
The Securities and Exchange Commission (SEC) has announced that it will need additional time to determine the fate of a proposed exchange-traded fund (ETF) focused on carbon credit futures contracts and Bitcoin BTC/USD. What happened: In a submit On Thursday, the agency announced that it will decide by June 24, 2024 whether to “approve or disapprove or initiate proceedings” for the 7RCC Spot Bitcoin and Carbon Credit Futures ETF.This delay signals the SEC’s desire for a deeper review of the proposed fund, which aims to invest 80% of its assets in Bitcoin and 20% in instruments that provide exposure to…
An installation by Maine Solar Solutions. Local solar installer Key solar solutions has introduced a 30-year warranty on solar energy components, believed to be the first long-term warranty offered by a solar installer in Maine. “We understand that choosing to invest in a solar electric system is an important decision for Maine homeowners,” said Sam Zuckerman, CEO of Maine Solar Solutions. “That’s why we’ve introduced a first-in-Maine 30-year warranty. It’s not just about providing the longest coverage in the state; it’s about providing our customers with peace of mind and fixed costs over the life of their solar system.” The…
The European Commission has selected the winners of the European Hydrogen Bank’s first auction, with bids below €0.50 per kg, while Chile and Namibia unveiled new hydrogen plans.

The seven projects were the winners of an oversubscribed auction That A total of 132 bids were submitted. Together, the winning bidders plan to produce 1.58 million tons of renewable hydrogen over ten years. said the European…
Solar installation solutions provider QuickBOLT’s Butyl Bottom Deck Mount has received Notice of Acceptance (NOA) approval from Miami-Dade County, the nation’s authority on structural testing for hurricane zones. This approval (Miami-Dade County, Florida. NOA 23-1122.07. Expires 04/25/2029) indicates that Butyl Bottom Deck Mount has met and surpassed the rigorous testing requirements mandated by Miami-Dade County for building products and materials, particularly in high-velocity hurricane zones. Butyl Bottom Deck Mount from QuickBOLT The Butyl Bottom Deck Mount by QuickBOLT is a deck-mounted attachment for solar installations on pitched rooftops. Its key features include a T-foot-shaped mount backed with peel-and-place butyl adhesive…
Bighorn Solar in Colorado. Credit: McCarthy Building Cos. The Colorado Renewable Energy Siting Coalition, made up of six conservation and environmental groups, has welcomed the introduction of a study bill that will examine current pathways for siting utility-scale renewable energy projects and assess the impact of these facilities on wildlife and communities to evaluate. Sponsored by Senator Chris Hansen and Senate President Steve Fenberg, SB24-212 requires the Colorado Energy Office, in collaboration with the state departments of Local Affairs and Natural Resources, to develop a repository of model codes and regulations for renewable energy projects and for Colorado Parks and…
With the so-called “network checker”, residential PV customers in Belgium can check whether there have been inverter failures in their local area. It comes after Belgian grid operator Fluvius launched a compensation scheme for those who are not reconnected within 30 working days of an interruption. May 3, 2024 Patrick Jowett Image: Jasminum Officinale/UnsplashBelgian electricity grid operator Fluvius has launched a new tool that allows all residential PV customers to see if there are any outstanding complaints regarding inverter failures in their region.The launch of the so-called “network controller” follows Fluvius’ announcement that it will compensate residential PV systems if…
In an era where energy independence is increasingly valued, DIY battery banks have emerged as a viable solution for individuals seeking autonomy over their power supply. These self-assembled systems allow users to store energy generated from renewable sources such as solar panels or wind turbines, providing a reliable backup during power outages or a sustainable off-grid power solution. In this guide, we’ll walk you through building your own DIY battery bank, from understanding the basics to solving common problems.Understanding battery banksBattery banks are the heart of any off-grid or backup power system, storing electricity for later use. They consist of…
If delivered, the Derrymeen battery will be the largest installed BESS facility in Northern Ireland with a 2-hour runtime. Image: SSE Renewables. Green energy developer SSE Renewables has purchased a 100MW/200MWh battery energy storage system (BESS) from Heron Energy in Dungannon, County Tyrone, Northern Ireland. If delivered, the Derrymeen battery will be the largest installed BESS facility in Northern Ireland with a 2-hour runtime. Subject to a final investment decision by SSE Renewables, the excavation-ready project will be built on a greenfield site outside Coalisland, approximately five miles from Dungannon. If final delivery is approved, construction could begin early next…
Finland-based optical solutions company ICS Intelligent Control Systems Ltd has announced a power improvement of approximately 3.8% in heterojunction (HJT) solar panels when combined with the patented Solar Energy Optics (SEO) light redirecting film during a test. Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE).The emerging HJT solar cell technology can achieve higher efficiency than traditional c-Si cells and even cells processed with PERC techniques. But the problem with power loss in the edge area of HJT cells has long been an obstacle to unlocking the optimal efficiency of these cells. By applying the ICS SEO film to the inside…
