California startup HahaSmart aims to become low-cost disruptor in solar
The first solar O-2-O platform (hahasmart.com) enables lower solar costs for homeowners and more business for small solar contractors
Metal Roofing Makes Solar a More Cost-Effective Residential Option
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
A Guide to Safely Installing Solar Panel Arrays to Any Property Type
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.

Optimizing Solar Plant Implementation
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?
One With The Roof
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.
Solar Energy Moves into a Brighter Future
Sun tracking is accomplished through azimuth and elevation (screw jack) drives that require a high degree of accuracy and durability.
Rail-less Residential PV Mounting
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
ASIC Based Current Transducers
The implementation of ASIC based current transducers opens up functionality that the traditional discrete component transducers could never achieve.
Using Elastomeric Roof Coatings to Resolve Existing Roof Systems & Solar PV Life Cycle Disparities
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.
A New Class of Rogowski Coil Split-core Current Transducers

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.
Corrosion Control for Wind and Solar Equipment
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.
Balance Of System Innovation "Clicks" for a Competitive Edge
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.
Aluminum Continues KnowledgeSurge in Cost-driven Solar
Light weight, strength and corrosion resistance represent three of the benefits. "Aluminum profiles can be made as structurally strong as needed for most applications,"
How to choose and implement current sensors
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.
