With billions of dollars invested and gigawatts of solar installed every month, savvy investors and owners understand that to maximize financial returns and optimize solar power plant performance, a well-thought-out plan for a complete operations and maintenance (O&M) program must be baked into the economics of any project before the first boots hit the ground. Single-axis trackers (SATs) have become increasingly popular because of the higher energy yield they produce compared to fixed-tilt systems. This white paper discusses and analyzes the factors to consider when evaluating tracker technologies from an O&M perspective.

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach – coupling energy storage to PV arrays with a DC-to-DC converter – can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
Key highlights from the report include:
• Long-duration storage is now commonly viewed as having an energy delivery time of at least four hours, and the need for it is growing.
• Renewable energy self-consumption is seen as the most promising application for long-duration storage.
• A Levelized Cost of Storage (LCOS) calculation is considered the most reputable selection criterion in determining which long-duration storage technology to deploy.
• The most promising technology for long-duration storage is flow batteries and the key criterion for selecting a given asset is cost, particularly the capital expense required.
After a decade of explosive growth in the residential solar photovoltaic (PV) market, in 2017 California saw its first decrease in annual residential solar installations. This paper suggests that the most probable cause of this downturn is the beginning of market saturation in the residential retrofit market (as differentiated from the new construction market). It also illustrates how the new construction market, which is growing rather than declining, can mitigate a downturn in the retrofit market when sufficient housing growth and aggressive new construction policies or initiatives exist. The analysis suggests that 15 - 20,000 jobs are at risk in California if steps are not taken to mitigate the downturn.
Most forms of infrastructure are being transformed with modern monitoring, data communication, data analysis, and remote control systems. The electric transmission system is poised to be the next sector. A number of proven, advanced technologies exist which can help optimize the existing transmission grid. These technologies can variously allow hidden transmission capacity to be identified and utilized, reduce power flow on overburdened lines, and/or reconfigure existing grid elements to optimize various operational scenarios. These advanced technologies can be applied singly or in combination.
Together with 3E - provider of consultancy services and software for sustainable energy systems - we have analyzed highly accurate irradiation data of more than 200 weather stations with state-of-the-art satellite derived data. How these compare and differ is described in the whitepaper.
Researchers from NREL and Clean Energy Group found that placing a monetary value on the ability of solar+storage to avoid losses during grid outages can significantly impact project economics and system design. Using data from Southern California Edison, researchers analyzed the economic case for solar+storage for three customer types (school, office building, and hotel) in Anaheim, California. In each case analyzed, larger PV and battery storage systems were found to be economical when the value of resilience is accounted for.

Traditional storage plus solar (PV) applications have involved the coupling of independent storage and PV inverters at an AC bus, or alternatively the use of multi-input hybrid inverters. Here we will examine how a new cost-effective approach of coupling energy storage to existing PV arrays with a DC-to-DC converter can help maximize production and profits for existing and new utility-scale installations. This new approach leads to higher round trip efficiencies and lower cost of integration with existing PV arrays, and at the same time opens up new use cases not possible with traditional AC-coupled storage.

Concentrated solar power (CSP) and concentrated photovoltaic (CPV) methodologies generate electricity by focusing a large amount of sunlight onto a much smaller area. To maximize efficiency, the sunlight needs to be accurately focused. Being off by even a single degree could result in a significant drop in efficiency, and the biggest impact to the cost of delivering solar energy is efficiency. As with most systems, the accuracy is limited by the accuracy of the sensors used in that system. There are a number of different types of sensors that can be used in these systems. This paper discusses why an absolute inclinometer is the most effective sensor solution and why the US Digital T7 is superior to other inclinometers available today.
SMA America compiled a white paper to evaluate the value of 1,500 V DC technology in power plants, citing that optimized stack design results in greater annual power production and higher availability. The paper looks at the role that inverters play in large-scale power plants, and the importance of superior technology to ensure long plant life and high performance.
In our view, Italy is on the edge of becoming one of the most attractive country for developing unsubsidized solar PV power plants. The continuous decrease of solar PV equipment cost, together with a positive fiscal framework evolution over the recent past, are driving down the LCOE for utility scale plants, allowing Italy to be a serious candidate for a new boom of utility scale solar development. The paper further discusses the rationales and the key challenges of our view.

Professional weather sensors form the heart of large solar plants supporting their operation and performance. Lufft was the first manufacturer to combine several sensors in one housing, bringing the largest multiparameter weather sensor family with 19 members into being. Many of them are well-suited for solar site assessment and continuous monitoring. The most commonly used one is the WS600 delivering data on temperature, air pressure, wind, relative humidity and precipitation. Through its open protocol, it can easily be attached to radiation sensors e.g. from Kipp&Zonen. Other models have an integrated Silicon, Second Class or Secondary Standard radiation sensor.
