“”…solar on sprawling, flat school roofs is an absolute no-brainer. It saves a ton of money for schools, which are always on tight budgets and reduces emissions overall. Virginia’s largest solar array on a school rooftop just came online

2024-09-10 All Warehouses, Distributions Centers Should Have Rooftop Solar
All US warehouses and distribution centers should have rooftop solar. “”And if all US warehouses and distribution centers adopted solar, then the equivalent of more than 112 million metric tons of carbon dioxide annually would be reduced. That’s like taking 24 million gas cars off the road for a year, or taking 30 coal-fired power

2024-08-30 Used EV Batteries Are Now Used For Battery Energy Storage Systems
This article has some valuable information – it’s worth reading. Badmouthers say used EV batteries will be filling up landfills. That’s false. The used EV batteries will have many years more use in Battery Energy Storage Systems. After that they will be ground up and recycled for their valuable metals. The future holds many, many

2024-08-20 Aussies Pay Half As Much To Install Rooftop Solar As Americans
This YouTube short from Electric Viking talks about how much money rooftop solar will save over their life. But what got me to notice was how much cheaper Australians pay to install solar. I guess the US charges very high tariffs on Chinese solar equipment and that causes the cost to go up.
2024-08-18 Solar Energy “Breakthrough” – Multilayer Perovskites
Perovskites are not a breakthrough, but making thin, flexible multilayer sheets flexible enough to coat surfaces is innovative. The main issue with Perovskites is they are not as long-lasting as silicon; they lose capacity in a shorter time. This breakthrough presumes this issue has been solved. https://www.ox.ac.uk/news/2024-08-09-solar-energy-breakthrough-could-reduce-need-solar-farms?utm_medium=email&utm_source=ted_talks_daily_newsletter&utm_campaign=daily
2024-08-13 Debunking Myths: “10 Reasons All Electric Is A Bad Idea”
Each point of the link is debunked. Top 10 Reasons All-Electric Is a Bad Idea #1.) “”Electric systems are awfully wasteful.”” This assumes that all electrical power is generated by thermal power plants. Yes, 2/3 of the energy used to heat the steam goes to waste and only one third gets to produce electricity. But

2024-08-12 Cannons Disrupt The Formation Of Hail Stones
This cannon is used in a vinyard and the shockwave is so powerful it disrupts the formation of hail stones. I’m seeing a lot of badmouthing solar panels that got broken by hail. Well, here is a possible preventive solution. https://www.facebook.com/reel/344539995276131?mibextid=9drbnH
2024-08-11 Solar Panels And Hazardous Waste
Most solar panels do not have lead or cadmium – they have to meet the ROHS – restriction on hazardous substances. If they do, the hazardous wastes are sealed inside. If panels are broken they are quickly replaced because the solar system is losing money as long as the panels are out of service. “”Based

2024-05-29 Solar Panel Controller To Charge Lead-Acid Battery
This is a simple charge controller that includes a dump load to dissipate excess power from the PV panel. D1 is the reference voltage that feed the 393 comparators, and its forward voltage changes with temperature. It would be better to use a low power LM317 to give a stable 1.25 volts. Instead of a
