Inside SolarAPP+ and NREL’s pursuit of seamless residential solar permitting

Inside SolarAPP+ and NREL’s pursuit of seamless residential solar permitting

June 3, 2021 at 10:38 am 0 comments

The hazy days of unknown delay times for home solar permitting, inspection and interconnection appear finally may be behind the industry now, thanks to the U.S. Department of Energy’s National Renewable Energy Laboratory’s (NREL) Solar Automated Permit Processing Plus — SolarAPP+ — software. Developed in conjunction with Underwriter Laboratories, SolarAPP+Read More

How smart tech is driving solar PV jobsite efficiency

How smart tech is driving solar PV jobsite efficiency

May 26, 2021 at 9:00 am 0 comments

Solar balance-of-system (BOS) costs are dropping like a stone, thanks in part to the jobsite efficiency gains brought on by new and developing smart technologies. Indeed, solar EPCs have increasingly adopted new jobsite efficiency technology over the past two years, and the trend is headed upward, suppliers say. These improvementsRead More

Critical Infrastructure: Solar carports anchor microgrids at facilities that need them most

Critical Infrastructure: Solar carports anchor microgrids at facilities that need them most

May 17, 2021 at 12:53 pm 0 comments

Solar carports, or canopies, are becoming a dual-purpose component of more microgrids that protect critical services locations from grid shortcomings. While both carports and microgrids individually have long been gaining ground among adopters, the combination of the two enables more site-constrained critical facilities to add solar reliability to microgrids, especiallyRead More

You down with VPPs? How the virtual power plant movement is going so far

You down with VPPs? How the virtual power plant movement is going so far

As has been the case with many good science fiction inventions of the last century, we are finally getting around to building virtual power plants (VPPs), or a software-and-wire linked network of small residential and commercial electricity generators, that together resemble a multimillion-dollar utility power plant. While the wires linkingRead More

Boosts and boasts: The latest data on solar tracker + bifacial PV module production yields

Boosts and boasts: The latest data on solar tracker + bifacial PV module production yields

It only takes one hurricane, tornado or wildfire for the value of a resilient home energy system to sink in. Add to such increasing natural disasters the unpopular new utility practice in California of Public Safety Power Shutoffs (PSPS) — a preemptive shut down of swaths of the grid toRead More

Residential BIPV in 2020: Solar shingles yield to roof-integrated innovation

Residential BIPV in 2020: Solar shingles yield to roof-integrated innovation

June 8, 2020 at 1:27 pm Comments are Disabled

The integrated solar roof has long been a solar technology goal — combining solar power with a watertight roof covering — but the category (often seen as just “solar shingles”) is perceived as too expensive or too experimental compared to the cost of separately installing solar and a traditional roof usingRead More

The concept of offering operations and maintenance (O&M) to solar asset holders is not new. A host of O&M companies now provide soup-to-nuts service for commercial and utility-scale PV plants. But none of these service providers is also an inverter manufacturer, much less one that offers a 99 percent inverterRead More

Corporate investors in solar energy are modifying their expectations and demands for future utility-scale solar projects, bolstering the profile of the industry as a long-term asset class, and altering PPA and contract terms that make more deals possible, said financiers at Intersolar 2020 in San Diego. The impact of thisRead More
