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.
Light weight, strength and corrosion resistance represent three of the benefits. "Aluminum profiles can be made as structurally strong as needed for most applications,"
Many new installations benefit from solid core transformers, and split core technology is not designed to compete with these. However, existing machines and building equipment have no way to add solid core devices without a costly shut-down of the system. New materials and technologies equip advanced split core current transformers for immediate retrofitting of high-performance and cost-effective condition monitoring, power metering and facility supervision systems.

PV connectors are part of a system, and how well they connect and disconnect along with the ease of assembly & installation is important to installers. Electrical standards for PV connectors have been established through the National Electric Code (NEC) and UL. However no design and/or contact standards exist. The ‘defacto' standard has not been uniformly accepted by manufacturers. The need for compatibility and interchangeability is clear.

Soiling of the panel glass is one of the major problems in the rapidly expanding solar energy market, with the attendant loss of efficiency and reduction in performance ratios. Now, there's a new, simple and very cost-effective alternative. Based on Kipp & Zonen's unique Optical Soiling Measurement (OSM) technology, DustIQ can be easily added to new or existing solar arrays and integrated into plant management systems. The unit is mounted to the frame of a PV panel and does not need sunlight to operate. It continuously measures the transmission loss through glass caused by soiling, so that the reduction in light reaching the solar cells can be calculated.
