While it is very common for solar installers in the U.S. to install so-called power optimizers in PV systems to meet the local electrical code requirements, these devices are subject to considerable controversy in the rest of the world.
America and other nations are taking a stance against Russia since the country invaded Ukraine. The Biden-Harris Administration established immediate sanctions, which negatively impacted America’s economic stability.
As with any investment, the two main ways to improve the ROI of a commercial PV system is to increase energy production (and therefore annual revenue) and decrease lifetime costs. Let’s take a deeper look at how this can be done in commercial PV installations.
Public airports across the U.S. face a similar challenge: a fixed revenue model with limited opportunity for growth. Fortunately, many have an untapped resource that they can turn into a source of predictable, long-term income – the open space around their runways.
To mitigate the increasing cost of running a utility-scale solar project, many owners and operators have switched their focus from CapEx to operations and maintenance (O&M).
In the most-likely scenario, the experts predicted that hub height for newly installed onshore wind turbines will reach 130 meters in 2035, rather than the 115-meter forecast offered in a 2015 survey.
On March 3, 2022, a serious power outage in Taiwan, happened. More than five million households and 500 industrial businesses were affected. Thanks to the SMA battery inverter, however, they were quickly back on the grid and supplied with power.
