Designing High Wind -Resilient PV Systems

Solar Under Storm Part II: Designing Hurricane-Resilient PV Systems February 17, 2020  |  By RMI, Laurie Stone and Christopher Burgess The last three years have seen major hurricanes wreak havoc on island nations. Hurricanes Harvey, Irma, Maria, and Dorian caused catastrophic damage to homes, infrastructure, and economies throughout the Caribbean basin. At the same time, the use of solar photovoltaic (PV) power …

Renewable energy prices are now significantly below those for coal and gas generation. It is now cheaper to save the climate than to destroy it.

Over the last decade, wind energy prices have fallen 70% and solar photovoltaics have fallen 89% on average, according to Lazard’s 2019 report. Utility-scale renewable energy prices are now significantly below those for coal and gas generation, and they’re less than half the cost of nuclear. The latest numbers again confirm that building new clean energy generation is cheaper than running existing …

The water-energy nexus at rivers can be resolved worldwide by 2050 as a consequence of the energy transition

Water-energy nexus can be resolved for thermal power plants #100RE. 96% of global thermal PP and 330 rivers are individually traced. 98% of water consumption can be avoided Water and energy are closely related, particularly in the current electricity generation based on thermal coal, gas, oil and nuclear power. The so-called water-energy nexus is a significant sustainability concern. However, a …

Accelerating Wind and Solar: Wind and solar have seen remarkable growth over the past few decades. Most of the limits on wind and solar integration that have been presented by critics have been proven overstated at best, if not outright false.

Solar represented only 2.4 percent of global electricity generation during 2018. However, the rate of growth is dizzying. The output from solar grew around 50 percent annually from 2007 through 2017, meaning that on average, its contribution to the power supply more than doubled every two years. Wind is further along, representing 5.5 percent of generation in 2018. However, it has been growing …

Solar farms can keep the lights on even at night: Trial shows panels can smooth voltage fluctuations in the UK National Grid

“Inverters” at the solar farm are usually used in the process of converting solar energy to electric current. But at night, when the grid is often less stable, the same equipment can adapt grid electricity to a healthier voltage. Chris Buckland, technical director of Lightsource BP, said the inverter acts like a distortion mirror by reflecting the energy network’s voltage …

Supporting an accurate value of solar

John Farrell, ILSR, Nov 2019, excerpt Minnesota’s value of solar policy had the benefit of development on the heels of successful value of solar policies in other jurisdictions, primarily Austin, Tex. The included components were written specifically into the enabling legislation based on the advice of experts from municipal utility Austin Energy, Clean Power Research, and clean energy economists. The …

Tesla provides transparent and easy commercial solar at $1 per watt

Sept 2019, Clean Technica excerpt Many will focus on how this makes it so easy to buy commercial sizes of solar. They are banking on you trusting the Tesla brand name to give you good pricing, quality, and reliability — enough so that you will just fill out the 12 fields and put the $100 on your corporate credit card. …

If this car is driven four days a week for a maximum of 31 miles a day, there’s no need to plug into an outlet (or ever gas up)

Toyota is trying to build a vehicle powered by the sun. “The solar car’s advantage is that — while it can’t drive for a long range — it’s really independent of charging facilities,” said Koji Makino, a project manager at Toyota. Put together the best solar panels money can buy, super-efficient batteries and decades of car-making know-how and, theoretically, a …

Virtual power plant: Sunrun and OATI will provide grid stability, earn compensation from Hawaiian Electric for managing and dispatching networked home solar and battery-stored energy to the grid

Clean Technica, Sept 2019 Sunrun, the United States’ leading home solar, battery storage, and energy services company, announced last week that it intends to participate in Hawaiian Electric Company’s emerging grid services market by delivering electricity from a virtual power plant made up of home solar and batteries.
