The 2017 National Electrical Code (NEC) will feature the new Article 691, which covers nonutility company, large-scale photovoltaic (PV) electric supply stations with generating capacities of at least 5,000 kilowatts (kW).
While most media coverage of solar power has focused on the industry’s steady growth, not all reports are rosy. According to the online electrical industry news source, Utility Dive, solar’s bright fortunes could be taking a slight dip on the horizon.
In a state blessed by an abundance of sun, one might expect the solar industry to bask in unmitigated regulatory support. But Arizona is not California, and the state’s homegrown controversy over rooftop solar has cast a dark cloud over the future of the market there.
Solar photovoltaic (PV) panels have an impressive lifespan. Manufacturers often estimate it at 25 years, though many units installed in the 1980s are still going strong today. At some point, though, even the hardiest of these panels will fail.
In the widening embrace of renewable energy, cities have become a catalyst. For example, San Francisco recently approved an ordinance requiring solar panels on all new residential and commercial buildings constructed in the city beginning in January 2017.
Energy consumer demand for distributed-energy resources (DER) is growing for a number of reasons—unexpected utility power outages, planned rolling blackouts, power quality problems, increases in power costs, etc.
A while back, I wrote about a house with 14 kilowatts (kW) of solar panels installed on the southern exposure roof. Voltage and current monitoring at the breaker panel prior to the solar panel installation had shown 10–12-volt (V) deep sags occurring as frequently as every 22 minutes.
In the drama surrounding the growth of sustainable technology, a few companies have found themselves occupying a large space on center stage. Recently, two of those companies shined the spotlights on their space with the prospects of a merger.
On June 28th, Facebook launched Aquila, a high-altitude, unmanned solar-powered airplane, for its first flight at Yuma Proving Ground in Yuma, Ariz.
Although the team has been running tests and practice flights for months, until this point, only a 1/5th scale airplane had been tested.
Bertrand Piccard landed in Abu Dhabi on July 25th at 8:05 p.m. EDT (Easter Daylight Savings Time) after completing a two-day solo flight in the airplane, Solar Impulse 2 (SI2), an aircraft powered 100 percent by solar power.
In places such as Arizona, where utilities and the solar industry bicker over pricing and metering policies, everyone suffers. In Los Angeles, where the same policies are embraced, everyone wins as increasingly larger projects come online.
The need to modernize the nation’s outdated electrical infrastructure has become something of an axiom in the age of renewables. Recognizing that need, the U.S. Department of Energy (DOE) has offered an incentive.
Route 66, has connected Santa Monica, Calif. and Chicago, Ill., since 1926 and, for a long time, was a major pathway for those travelling across the United States. With the creation of the interstate highway system, the road's popularity plummeted, and today, it is largely used as a scenic route.
When it comes to harnessing the power of the sun, there’s a lot more to it than just throwing down a towel and catching some rays. Ask J.M. Electrical Co. Inc. The Lynnfield, Mass., contractor with 140 electricians just completed an installation that was anything but typical.
Like the desert in summer, the solar power controversy in Arizona continues to sizzle. The drama involving Arizona Public Service (APS), net metering and solar power has been well documented. Now, a new storyline has emerged.
