Mistaya Releases Windographer 1.1

Mistaya Engineering Inc. announces a major update to its wind data analysis software Windographer. The new features allow users to open raw wind data files, detect and remove problem data segments, and analyze tower shading, wind shear, and wind turbine performance in greater detail.

CALGARY, Alberta - March 28, 2007 - Calgary-based Mistaya Engineering Inc. today announced a major update to its wind data analysis software Windographer. The new features allow users to open raw wind data files, detect and remove problem data segments, and analyze tower shading, wind shear, and wind turbine performance in greater detail.


"The new features incorporate many of the suggestions we received from customers," said Tom Lambert, president of Mistaya Engineering, "and early feedback has been very enthusiastic."

"We have found Windographer to be a very helpful tool for processing and analyzing wind data. The quality control tools ensure that the data is accurate and the statistical and graphics tools make reporting a breeze," said John Vanden Bosche, principal engineer at Chinook Wind.

New Quality Control Module

The new Quality Control window lets users find and fix problems in the data set caused by icing events or sensor malfunctions. They can search for data anomalies using simple visual inspection of the time series graphs, or by defining search rules that might detect, for example, extreme values, flat line segments, abrupt changes, or discrepancies among anemometers. Users can delete problem segments, or even replace them with synthetic data.

Data Import Improvements

Windographer can now open the .RWD files written by the popular Symphonie data logger from NRG Systems. It can also append data to an existing data set, and open multiple data files at once. These changes save time by eliminating the need to process or collate data before analyzing them in Windographer.

Anyone interested in Windographer can download a 60-day free trial version from www.mistaya.ca/windographer.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
