Triton Powers Through Two Winters North of the Arctic Circle

Enables Puhuri to exploit wind potential in Arctic conditions

The Triton Wind Profiler manufactured by VaisalaOnline  —  Vaisala’s Triton Wind Profiler has shown exceptional performance across two winters in the northern reaches of Finland.

With two Vaisala’s Triton Wind Profilers measuring the wind for Finnish developer and operator Puhuri Oy, Vaisala has demonstrated the unmatched resilience of the system in extreme winter conditions and the strategic and logistical advantages of remote sensing for wind energy firms in cold climates across the globe.

Vaisala Ships First Units of SP-12 Solar Weather Station

Turn-key solar measurement solution


SP-12 Solar Weather Station Installed (Click Image for Details)

Online — Vaisala has launched a new, ready-to-install solar weather station that provides all of the instrumentation required by solar project developers, operators and their engineering teams for best practice resource assessment and monitoring.

The SP-12 Solar Weather Station, available in multiple configurations, measures the full range of environmental parameters that affect solar project performance.

The SP-12 Solar Weather Station, mounted on a 2-meter tower and booms, combines industry-leading Kipp & Zonen pyranometers with Vaisala’s next-generation WXT536 multi-weather sensor, capable of measuring wind speed and direction, ambient temperature, humidity, pressure and rainfall.

Online  —  Wildfires engulfing large swathes of the U.S. West Coast this summer have had a significant impact on the performance of solar PV projects operating in the region.

Irradiance shortfalls caused by smoke cover are clearly visible on monthly performance maps produced by Vaisala, a global leader in environmental measurement. These are estimated to have caused a substantial impact on project revenues during peak generation season.

Large-scale forest and bush fires have become a common occurrence throughout the American southwest, driven by a number of factors, including increasingly hot and dry conditions in the summer months.

Low Irradiance in 2015 Impacts Solar Projects in Southern USA

Vaisala annual performance study illustrates effects of anomalous weather

US_Solar_MapOnline — Vaisala has released solar performance analysis revealing that solar irradiance levels were 5% below long-term averages across the southern U.S. in 2015.

The corresponding impact on project performance was felt most notably during the first two quarters, when operators in emerging solar markets, including Texas, saw irradiance levels more than 10% below normal.

While the majority of operational solar capacity in the U.S. is concentrated on the East and West Coasts, the industry has identified the southern U.S., notably Texas, as a region with considerable solar development potential.

300 MW of new solar projects were scheduled to come online in Texas in 2015, and a construction boom is anticipated in the coming years as the solar sector looks to emulate the success of wind energy in the region. Continue reading
