Large-scale solar + storage is on the drawing boards of a host of major EPCs, with the current round of demonstration plants leading to wholesale installations by 2020, say several industry players. “While we are early in the deployment cycle for large-scale solar + storage, we expect a ramping atRead More

When a $4.5 billion-a-year employee-owned solar EPC determined how to best maximize local trainee headcounts on projects, the solution not only made strong economic sense but also presented an unusual competitive edge. Indeed, McCarthy Building, based in St. Louis, has constructed a reputation of having one of the best workerRead More

More solar installers are adding products and services to their core offering, both to help customers fulfill their sustainable energy goals and to drive ancillary revenue. Products like battery storage, EV charging stations, Smart Home devices and electrical upgrades are natural add-ons for many customers. At the same time, moreRead More

Solar power is starting to bolster the energy capacity in northern climes, especially across Canada and Alaska where diesel generators take the cost of electricity sky high. Both fixed-tilt and tracker installations are expanding rapidly in this region, as advancing solar technology helps cope with bitter cold and erratic daylight.Read More

Solar customer data is increasingly being used for quantifiable savings by solar installers, developers, energy arbitrators and utilities. The software companies specialized in gathering and aggregating this data on residential, commercial and industrial levels are also building more functional systems that will help to standardize energy efficiency and asset managementRead More

Shaving the peaks off commercial and industrial (C&I) electric bills is the top revenue stream for energy storage systems, and given the trend in increasing utility charges for time-of-use consumption, peak shaving can pay for a system in as little as three years, system providers say. Just how high theRead More

It’s always reassuring when solar technology moves faster than a federal regulator, even if it is a well-intentioned agency like the U.S. Labor Department’s Occupational Safety and Health Administration (OSHA). In this recent case, a new crop of solar tile replacements that support rooftop mounting systems are eliminating the needRead More

Solar inverter intelligence and monitoring has evolved mightily over the last few years, from silent rows of capacitors to today’s circuit-programmable, WiFi-enabled guardians of PV arrays. These systems sense minute changes in operation and advise system managers of options, in real time, for energy management and O&M (operations and maintenance).Read More

The days when a residential or commercial solar installer did not need to know the difference in performance between lead-acid and lithium-based batteries are over. Battery storage has emerged as an unavoidable complement to solar, slashing peak charges and outwitting utility time-of-use charge games, not to mention saving microgrids fromRead More

Community solar has taken off within the renewable energy development leagues, melding the interests of residential and commercial or industrial customers, as well as the local utilities. While the inclusion of low- and middle-income (LMI) residential customers are widely enabled by state legislation on community solar, specific carve-outs or percentageRead More
