The recent POWER magazine webinar “Hardening the Grid in the Face of Unprecedented Challenges” with- New York Power Authority , IEC - Israel Electric Corporation חברת החשמל לישראל בע"מ , and Prisma Photonics CEO Dr. Eran Inbar, is now available. This group of experts, including our own Amir Livne , discussed how climate-related extreme weather and rising electricity demand impacts the grid and how grid modernization and adopting solutions like Prisma’s which offer dynamic line ratings can be a solution Don’t miss these insights from industry leaders! https://lnkd.in/duQ5nyfA #EnergyTransition #GridInnovation #WebinarReplay #PrismaPhotonics #ResilientGrid #PowerGrid #RenewableEnergy#GridResilience #DynamicLineRating #Webinar #EnergyInnovation

Previous research has shown the feasibility of powering #LoRaWAN #sensors using high-energy ambient or wireless transfer power sources. This article extends this work by exploring the #boundaries of using low-energy #radio-#frequency (#RF) ambient sources. Ambient RF energy harvesting is an attractive option, but it is more challenging due to the low levels of energy density typically available.Using an analytical LoRaWAN device model and RF energy data collected from around the world, a systematic investigation of the design and environmental space is performed. The main contribution of this article is to identify the boundaries of feasibility for powering LoRaWAN sensor nodes from ambient RF energy. These boundaries include design and environmental factors. ---- Joseph Finnegan, Kyriaki Niotaki, Stephen Brown More details can be found at this link: https://lnkd.in/erNYzGJd

Solar Radiations: Global Radiation: This is the total amount of solar radiation that reaches the Earth’s surface, combining both direct beam radiation and diffuse radiation. It represents the total solar energy available at a given location and includes: Direct beam radiation (from the sun directly) Diffuse radiation (scattered by the atmosphere) Reflected radiation (also known as albedo radiation, from surfaces like water, snow, or sand). Direct Beam Radiation: This is the solar radiation that travels in a straight line from the sun to the Earth's surface without being scattered. It is the most intense form of solar radiation and is available only in areas with clear, unobstructed sunlight. Solar panels with tracking systems often aim to capture maximum direct beam radiation. Albedo Radiation: Also known as reflected radiation, this is solar energy that reaches the Earth's surface and reflects off of various surfaces (such as snow, water, buildings, etc.) back into the atmosphere. Albedo can affect the amount of solar energy available to adjacent or elevated surfaces and varies depending on the type of surface and its reflectivity. In summary: Global radiation = Direct beam + Diffuse + Albedo. Direct beam radiation is from the sun directly. Albedo radiation is sunlight that reflects off surfaces back into the atmosphere. #SolarEnergy #SolarRadiation #GlobalRadiation #DirectBeamRadiation #AlbedoRadiation #SolarPower #RenewableEnergy #CleanEnergy #SolarTechnology #EnergyScience #SustainableEnergy #SolarInnovation

Places filters should be: water sources, furnaces, and your inner monologue before speaking. Places they shouldn’t be: on your solar simulator. Lose the filters with an LED solar simulator. #Chemistry, #Photovoltaics, #Science, #Innovation, #EngineeredSunlight https://buff.ly/43OhB1O

Space-based solar power (#SBSP) collects sunlight in space and transmits it to Earth via microwaves or lasers. It works 24/7 since there’s no night or weather interference. Without the interference of the Earth's atmosphere, which scatters and absorbs sunlight, space-based solar systems can collect more energy. This means potentially higher efficiency compared to terrestrial solar panels. It’s more efficient than ground-based solar but is expensive and technically challenging. It could power space missions and reduce fossil fuel use, but the energy transmission methods need more testing for safety. #Technology #EnergySources

The SLS is getting a new roof! As part of the SLS 2.0 upgrade, the old tar paper of the #SwissLightSource #SLS is currently being replaced by aluminium profiles with photovoltaics. When SLS goes back into operation in 2025, it will provide more intense synchrotron light and at the same time require up to 33% less electricity than before. The new solar roof will contribute to this. #UpgradingSLS #SLS2.0 #LightSourceScience #WorldChangingScience #SynchrotronScience #ScienceForSociety #ScienceNeverStops #MoreBrilliantLightForResearch #LargeResearchFacilities #PSIStories #PSICampus

Diving into UV Resistance #2: The Power of Innovative Cell Design 🧪 A key factor in the UV resistance of #Trinasolar's Vertex N series modules lies in our innovative cell design and structure. Our solar cells are meticulously engineered with a membrane that balances light self-absorption, minimal reflection, and effective UV blocking. This ensures exceptional UV resistance while maintaining high efficiency. 💡 Further enhancing performance, a passivation film layer is incorporated using our advanced technology and processes, boosting the efficiency of our solar cells. 🚀 Stay tuned as we continue to explore the UV resistance of our TOPCon modules. Next time, we'll examine our industry-leading control standards and their impact on our module’s durability and performance. #SolarPV #TOPCon #Innovation #RenewableEnergy
