Caribbean islands are starting to shift away from importing expensive fossil fuels, using instead their own abundant sun and wind to make electricity. However, their frequent hurricanes can put a damper on solar energy generation. Researchers at the Department of Energy’s Oak Ridge…

The installation waiting period for residential rooftop photovoltaic (PV) systems in Austria has been cut in half to three months, according to a survey conducted by solar industry association PV Austria. The duration from initial planning to installation has shrunk to three months recently from a previous timeframe of six to twelve months in 2023, the association said on Tuesday. “The time is perfect now: The PV industry is well prepared, and the acquisition costs for installing a PV system are currently unbeatable. With the new VAT exemption, the path…

Abstract Maintaining a power balance between generation and demand is generally acknowledged as being essential to maintaining a system frequency within reasonable bounds. This is especially important for linked renewable-based hybrid power systems (HPS), where disruptions are more likely to occur. This paper suggests a prominent modified “Fractional order-proportional-integral with double derivative (FOPIDD2) controller” as an innovative HPS controller in order to navigate these obstacles. The recommended control approach has been validated in power systems including wind, reheat thermal, solar, and hydro generating, as well as capacitive energy storage and…

If you don’t want to purchase your solar panel system upfront with cash, you have a few options besides solar leases. Here’s how solar leases stack up against the two other standard solar financing methods: Solar leases vs. power purchase agreements You’ve probably heard solar leases and power purchase agreements (PPAs) used interchangeably and for good reason! These two financing options are very similar. The critical difference is that with a solar lease, you’ll have a fixed monthly payment, whereas with a solar PPA, you’ll purchase the power generated by…

To celebrate Earth Day, Performance Food Group on April 22 held an open house event in Gilroy to show how they have created a sustainable distribution model at the company’s local facility. In collaboration with a number of vendors in the transportation and distribution industries, the company’s operation on Monterey Street south of town is complete with zero-emission trucks and refrigeration trailers, high-capacity charging stations, solar power and on-site high-tech battery storage.  While some aspects of the distribution facility’s electric power systems are not yet online, Performance Food Group says…

Solar energy is not only the most abundant energy on earth but it is also renewable. The use of this energy is expanding very rapidly mainly through photovoltaic technology. However, electricity storage remains a bottleneck in tackling solar resource variability. Thus, solar thermal energy becomes of particular interest when energy storage is required, as thermal energy storage is much cheaper than electricity storage. The objective of this paper is to make a short update on the CSP (Concentrated Solar Power) market as of the year 2023. It is based on…
