Is It A Good Idea To Buy Used Solar Panels?

| July 30, 2019

Discarded photovoltaic panels pose a quandary for waste managers because they contain both low levels of toxic heavy metals, and valuable elements like silver and tellurium, so they probably shouldn’t just go into a landfill with ordinary refuse like diapers and styrofoam. And as residential panels surge in popularity, more cities are having to figure out what to do with solar trash. “Local governments are freaked out. They are starting to get solar panels and they don’t know what to do with them,” said Dustin Mulvaney, an environmental studies professor at San Jose State who is working on answers to that question. But in on that December day in Berkeley, the solar panels didn’t go to a landfill, or a hazardous waste facility, or even some photovoltaic recycling factory. Instead, a crew from the local salvage company Urban Ore intercepted them, hauling the load back to their property across town.

Are Solar Workers ‘Essential’? The Industry May Soon Find Out

Article | March 23, 2020

The U.S. solar industry is preparing to argue that its workers are essential to the economy as it copes with a growing pile of government-mandated shutdowns to combat the spread of COVID-19. State-, county- and city-wide shutdowns, which are already in place in California, the nation's largest solar market, as well as New York and Dallas County, Texas, largely called for employees of “nonessential” sectors to stay home; the orders now cover about 20 percent of U.S. residents, according to the New York Times.

How Artificial Intelligence is changing the Energy Sector

Article | April 9, 2020

Artificial Intelligence, or AI, has gained relevance in many different fields of our life, using machine learning to analyse historical and new data in order to make predictions, improve control operation and perform tasks much faster than a human and with more efficiency. The energy sector is using AI to increase energy efficiency by reducing consumption, improving energy storage and grid stability, making predictions about energy consumption, to have more accuracy to find oil & gas and many other applications. When it comes to renewable sources, AI is improving the weather forecasts for the development of new plants and to make better planning of control & maintenance. Let’s take a look in some projects and how they are affecting the energy sector.

2020: The Year of Convergence in Corporate Renewables

Article | February 10, 2020

The rapid growth of corporate renewable procurement has been nothing short of a buyer-driven revolution in the United States’ electric sector. Almost 20 gigawatts (GWs) of corporate power purchasing agreements (PPAs) were completed in 2019 across the globe, up from 13 GWs of corporate PPAs in 2018 and triple the numbers from 2017.1,2 And the majority of this growth has come from the United States. Fortunately for those of us committed to renewable energy, we expect this trend to continue. But as should be expected in such a dynamic, buyer-driven sector, we are starting to see some noticeable shifts in the marketplace as it evolves and grows. I wanted to highlight some of the trends Constellation is watching for this year.

How EV Chargers Help Campus Energy Ecosystems Evolve

Article | March 6, 2020

Electric engines are incredibly efficient, getting useful work out of 85 percent of the energy that goes into them. Gas engines only get 30 percent, wasting a lot of the energy we pay to fill them up with. That one fact drives intense fuel cost savings for electric vehicles, a clear win for a campus shuttle and bus conversion. But switching from gas to electric also opens up a world of operational resilience, energy independence and sustainability — with the right implementation of electric vehicle charging technology.
