This article is only available to GBA Prime Members Roughly 2400 megawatts of new residential solar was deployed last year, the equivalent of 7.5 million 320-watt modules. That’s a big investment. Ever wonder what prevents all those panels from blowing away in a stiff breeze?Solar mounting hardware—the racks, clips, and bolts that keep solar modules in place—is a world all but invisible once the panels are installed. With any luck, homeowners will never have to worry about, or even see, the equipment over the 25-year-plus lifespan of their solar arrays. That’s what manufacturers and installers are banking on.To that end, the industry has developed a variety of mounting systems that keep modules in place on virtually any type of roof, even in high-wind regions like south Florida. When a rooftop arrays isn’t feasible, a ground-mounted array is another option.Hardware represents an estimated 3% of the overall cost of a residential solar array, according to data cited by EnergySage, a Boston-based firm that connects customers with solar installers. Hardware is the essential foundation of any installation, even if most homeowners are blissfully unaware of it.“In our experience, most people don’t really want to know or need to know about that,” says Thomas Tutor, a branch manager for Maine-based Revision Energy. “They trust us to install it well and use high quality equipment that we’re going to stand behind regardless. So we make sure we choose equipment we believe in.”Here’s a rundown on the variety of mounting options installers have to choose from.Most residential solar arrays go on the roof where they’re safely out of harm’s way. The Solar Energy Industry Association, a trade group, lists a dozen and a half manufacturers of solar mounting hardware at its website, so installers have lots of options when it comes to choosing… Start Free Trial Already a member?

Small Business Cybersecurity Threats and How to… Related Posts Follow the Puck Long-time players of ’80s role-playing game Cyberpunk 2020 and the more recent Eclipse Phase are acutely aware of the potential uses and risks that come from swarms of intelligently-connected nano-scale machines. In science-fiction worlds commonly depicted in these games, as well as an entire genre of movies, books, and video games, nanoswarms are old hat.But, what if nanotechnology could deliver these incredible small, wirelessly-connected machines? How would they communicate? What practical purpose would they serve in a real-world scenario?As it turns out, there are scientists and researchers working developing this very type of technology. Devices that measure little more than 100-times the size of a single strand of human DNA that can navigate through, and transmit data from, your bloodstream.This makes it an incredible useful technology for medical research and care. Patients would benefit from having real-time analysis of their body down to the smallest level. Tests that today require exposure to radiation and other potentially harmful elements could one day be performed by nano devices positioned throughout the body.Nanoswarms could have many usesOther uses for the technology would include environmental data gathering, inventory management, and industrial monitoring.There’s even a dedicated, and well funded, government initiative for developing nanotechnology called the National Nanotechnology Initiative. This initiative, which has received over $22 billion in government funding since 2001, is tasked with providing the resources for the development and advancement of nanotechnologies as they make their way from concept to market.In order for these devices to work efficiently, they will need to be able to transmit data between them in a type of nano-scale Internet of Things.There are several different possibilities being explored by researchers, including a dedicated team at Georgia TechBecause they’re so small, their ability to send and receive data will be very limited. They wouldn’t be able to, for example, connect to your wi-fi network directly. However, they could pass information between each other to a type of nano-router that is slightly larger than its individual nodes and more equipped to process and transfer information to a gateway.Whatever the case will be, it’s going to be interesting to see the Internet of Things evolve over the next decade. As it continues to grow, its devices may well shrink.

Prime Minister, the Most Hon. Andrew Holness, says the sixth-form option in high schools provides a unique opportunity for students to develop leadership qualities and should be encouraged. “Sixth form was a particularly interesting and important experience for me. That’s where I developed most of my leadership skills and abilities. That’s where I got the grooming for leadership. I think sixth form is such a critical part of the school experience, now that more and more students are not just leaving school at fifth form,” he said. Story Highlights Addressing the 30th Anniversary Banquet of the St. Catherine High School Class of 1988, at the Jewel Runaway Bay Beach and Golf Resort, Runaway Bay, St. Ann, on July 14, Mr. Holness said to this end, he is spearheading an effort to build a state-of-the-art sixth-form block at his alma mater (St. Catherine High), which will be used as a template for other high schools across the island.

I think sixth form is such a critical part of the school experience, now that more and more students are not just leaving school at fifth form,” he said.The Prime Minister noted that in light of such widespread interest, it is now incumbent on the nation’s high schools to put the facilities in place to accommodate the demand.Mr. Holness said that a team has already been assembled to start working on the design and that he expects that the (St. Catherine High) facility should be completed within 18 to 24 months.“I visited the school on Labour Day (May 23), and we have settled on a location. It will be central between the junior and senior campus, and some funds have already been committed. While the timeframe is anywhere between 18 months and two years, it could well be earlier based on the interest being shown by many of our past students,” the Prime Minister said.The Ministry of Education, under the guidance of portfolio Minister, Senator the Hon. Ruel Reid, has long been pushing for more schools to implement sixth-form programmes.To that end, Senator Reid said the Government has implemented a textbook rental for sixth-form students in the coming school year, so as to offset cost for students who have opted to continue their high-school education, as opposed to moving on to college or taking a break from school.“While sixth form can be an expensive venture, we would rather students remain in school as opposed to leaving and not having anything to do,” the Minister said in a recent interview.“We feel that by implementing the textbook rental, we can give parents a much-needed break on the cost of having students moving on to sixth form,” Senator Reid added.
