Assessment Tools 101

This equipment and software tells families and plant managers how their solar panels are performing. For residential systems, such monitoring equipment tells whether or not the solar arrays working and how well. But as solar arrays are built larger, the risk and magnitude of trouble also grows, which makes the equipment all the more necessary. There are several arrangements to the... Read More
Operations and Maintenance 101

The delivery of solar power without any disruption maintains the stream of economic value generated by each kilowatt hour of production, and proper service is a critical component to ensuring optimal performance while minimizing the risks of downtime. But installing solar arrays are just the beginning. Without proper operation and maintenance, those 25- year warranties won’t be... Read More

Putting out the fire in PV systems
The threat of PV systems starting fires is an unfortunate reality. Since the Bakersfield, CA fire in early 2009, the solar industry has been searching for solutions that not only detect potential fire threats but more importantly stop the problem before it starts. Local jurisdictions have been calling for solutions to these problems and the new 2011 National Electric Code (NEC)... Read More
Redesigned panel now snow, salt, and hurricane tollerant
Using SolidWorks design and simulation software, Solar Infra developed a more rugged solar array for use in areas that once were environmentally prohibitive. Harnessing the sun’s energy can be challenging, especially when some of the sunniest regions have environmental conditions that preclude traditional solar modules. Standard solar arrays are often installed no less than 25... Read More
Avoiding arc-flash
An arc flash with 1000 A or more can cause substantial damage, fire or injuryArc flash is a dangerous risk among those in the power industry. Arc flash is an electrical breakdown of the resistance of air that results in an electric arc, which can occur where there is sufficient voltage in an electrical system and a path to ground or lower voltage. Feeder protection relays,... Read More
