The white paper, developed by members of SEIA's Solar Quality Assurance Working Group, provides recommended best practices on everything from contractor qualifications to the design and actual installation of a solar photovoltaic (PV) system.
With the support of industry leaders, the Solar Energy Industries Association (SEIA) and The Solar Foundation today are unveiling the Solar Automated Permit Processing (SolarAPP) initiative, which will streamline permitting and slash the cost of solar installations.
The first solar O-2-O platform (hahasmart.com) enables lower solar costs for homeowners and more business for small solar contractors
Installing a solar system on metal will increase the modules' performance and decrease energy and installation costs as compared to other common roofing materials. Plus, metal also has other environmental benefits
As the world continues to shift towards alternative energy sources, solar power will only continue to grow. Technologies will come and go and the astute product providers will continue to innovate.
Enabling High-efficiency Passivated Emitter Rear Contact (PERC) Solar Cells
In this paper, we will focus on a theoretical study and its application to a concrete site. We will try to answer the question: How can we optimize the implementation of horizontal trackers on a solar plant?
Installers working on a tile roof must deal with particularly difficult challenges. Tile roofs are manufactured from many types of materials, including clay, zinc coated aluminum, concrete, wood and fiberglass, all of which come in a wide range of shapes and sizes. Installing solar panels on a tile roof takes more time than traditional asphalt shingle roofs and often requires additional framing.
Sun tracking is accomplished through azimuth and elevation (screw jack) drives that require a high degree of accuracy and durability.
By providing a pre-engineered kit that incorporates the all-in-one concept (fasteners, flashing, brackets and bonding plates, all from one source), Roof Tech products are easy to understand and can be standardized for any array configuration
The implementation of ASIC based current transducers opens up functionality that the traditional discrete component transducers could never achieve.
Installing a white reflective "Cool Roof" coating is an inexpensive solution to extend the existing roof service life and synchronize the roof with the solar array service life.
Until now Rogowski coils have delivered at best a 2% positioning error. With this improvement, the error due to the positioning of the conductor is specified at a maximum of 0.65% of the measured value for a 15mm diameter conductor irrespective of where it is positioned, even if it is adjacent to the coil clasp.
Coatings are the first preventative measure for all of these assets. Since most are being deployed in desert areas or mountainous areas or along the coasts, or sometimes in the water, choosing the right coating is imperative to achieve design life.
The reduction in module costs forces manufacturers to add value in other ways, beyond the module, by introducing advancements in BOS and manufacturing. The PV BOS market in general is in a healthy state and equipment revenues are projected to increase from $17 billion in 2011 to about $24 billion in 2016, according to IMS research. Monitoring hardware, mounting structures and tracker systems are expected to capture a growing share of the market.

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
