As soon as solar started being introduced to the grid, operators and engineers raised concerns about solar resources causing instability. Is it possible, however, for utility-scale solar PV plants to provide grid reliability services? Mahesh Morjaria, vice president of PV systems for First Solar, says yes.
Over the summer about 33 customers in Pacific Gas and Electric’s (PG&E’s) territory started a new journey with their utility. PG&E is hoping that through this and other pilot projects, it will learn how responsive batteries, solar PV and smart inverters are when they receive a signal from the utility. [...]
Big solar farms helped create a power-grid predicament in California. And now they’re offering to help solve it. Solar panels have proliferated in the Golden State, flooding the grid with power supplies in the middle of the day when the sun’s out — and then quickly vanishing after sunset. [...]
In recent years, perovskites have taken the solar cell industry by storm. They are cheap, easy to produce and very flexible in their applications. Their efficiency at converting light into electricity has grown faster than that of any other material — from under four percent in 2009 to over 20 percent in 2017 — and some experts believe that perovskites could eventually outperform the most common solar cell material, silicon. [...]
The solar industry is large enough to seek U.S. Department of the Interior (Interior) regulatory relief, irrespective of any debate over climate change. The President-elect is skeptical of anthropogenic climate change. [...]
New installed renewable energy capacity surpassed coal for the first time last year, the International Energy Agency reported recently. It means that we added more wind and solar to our global energy system than oil, gas, coal or nuclear power combined — a trend that is expected to continue over the next five years. [...]
The U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy sees the potential of drones in advancing the solar industry. [...]
