Solar PV Carousel Trackers for Building Flat Rooftops
ABSTRACT Herein, a SunTrack Carousel tracker is described for mounting on residential or commercial building flat rooftops in order to produce more k\Vh per kW relative to fixed PV modules. The JX Crystals (JXC) fixed-tilt / azimuth carousel is a low profile tracker designed to distribute weight evenly over a large area and for low wind resistance on the roof. Multiple JXC SunTrack Carousels have ...

What is a horizon sensor? The Solar MEMS HSNS
Space sensors are our speciality and our vocation. We have great experience in working with different types, such as solar sensors, star trackers and horizon sensors. In this article we will be looking at the last of these, the horizon sensor, which can determine with precision and reliability the attitude of a vehicle or satellite by taking the Earth’s horizon as its reference. We explain ...

Utility-Scale Solar: Maximizing Project Profitability with Trackers
Watching the prices recently for utility-scale solar power-purchase agreements has felt a bit like being a spectator at an ultra-competitive Olympic event, where each successive race delivers a new world record. The headline-grabbing 1.79 cents per kilowatt-hour tender announced in Saudi Arabia this past October is just one indicator of a global trend, in which PPA prices have been steadily ...

Near Term Lower Cost Solar Electric Power for US Commercial Customers
Market Opportunities The first market for PV electric power panels was for space satellites. While the single crystal cells used in these panels made these panels very expensive, this was unimportant for that market. That market emphasized reliability, not cost. As these panels came down to earth for off-grid remote applications, again the emphasis was on reliability and low maintenance, not ...

Array Technologies and DuraTrack at Roadrunner Solar
With more than 1.2 million solar panels, Texas’s Roadrunner solar plant is one of the largest of its kind in the world. In fact, by the time its second phase of construction is complete later this year, it will be the largest operational solar farm in Texas. The plant has created hundreds of local jobs and become a beacon in the march toward innovation and sustainability, promising to ...

Different Components of Solar Radiation
Many people have asked us for an illustration that gives a simple overview of the three components of incoming short-wave solar radiation: direct, diffuse and global. We've created a drawing that we hope will make this clear.Direct Radiation The basis of the measurement is a SOLYS 2 sun tracker pointing a CHP 1 pyrheliometer at the centre of the sun. The CHP 1 has a full opening view angle of 5° ...

Part 3: Why PV Trackers Are a Critical Component of a Risk Profile for Utility-Scale PV Solar Lenders and Insurers
Every aspect of the PV solar project plays a part in risk. Plant design, available technology, and risk mitigation features that can be built into a tracker can affect all elements of a solar assets long-term risk profile. Trackers are one of the major inputs of the risk equation. In this final post of our 3-part series on risk mitigation for investors and insurers, we’ll talk about ...

Flocking to a Utility-Scale PV O&M Solution
Operating and maintaining a utility-scale photovoltaic (PV) solar power plant is a time-consuming and expensive proposition. However, there’s been a unique innovation in PV plant operation – though it comes from a simple and decidedly old-school source. Sheep’s New Role in Lowering PV Plant Operations and Maintenance Costs You read that correctly. Sheep are now being used for ...

Tracking the Sun’s Path for the World’s Largest Solar Concentrator
In early 2023, the world’s largest and most efficient solar concentrator was installed in Western India to power a hospital and research center. The impressive construction will produce steam for multiple applications as well as electricity for air conditioners. To maximize irradiance yield, the engineers are aligning the 26-ton concentrator with the path of the sun, utilizing data from the ...

How to Choose the Right Sun Tracker?
A complete measurement of solar irradiance includes global (GHI), direct (DNI), and diffuse (DHI or DIF) radiation. To accomplish this, a high-quality solar monitoring station typically comprises an automatic sun tracker fitted with instruments to measure these components individually. Depending on the application, long-wave radiation and reflected short-wave radiation may be added to provide the ...
