WS500-UMB and WS503-UMB compact weather stations monitor large solar plant in the Imperial Valley

The Imperial Valley Solar Company (IVSC) has built the largest photo-voltaic power plant of the US. The 360 million U.S. dollar Imperial Valley Solar plant is one of five planned plants in this region. It is the first to be connected to the public electricity supply of San Diego Gas & Electric energy service. Accurate weather monitoring in real-time and accurate weather forecasts by the Lufft sensors, allow public utility service providers to take advantage of the predicted available energy from renewable sources. Thus, shortages can be avoided by efficient performance management of electricity and other energy resources.

The WS500- and WS503-UMB all-in-one sensors are an important part of this project. Our longtime partner and supplier of measurement and communication solutions Trimark Associates was responsible for planning, implementation and monitoring of the Imperial Valley Solar 1 plant. The decision to use Lufft weather sensors for monitoring was taken because of their high quality. Professional weather sensors are normally used only in the industrial sector and are highly reliable. But also the low maintenance requirements convinced the executives at Trimark Associates

National Guard of Virginia relies on photovoltaics monitoring by Lufft sensors

The Virginia National Guard 183rd Regiment decided to complete a solar installation at their Regional Training Institute (RTI) at Fort Pickett, VA. The project, a $2.2 million, 488 kilowatt solar array that measures 10,000 square yards and consists of nearly 2,000 individual solar panels, provides the RTI with nearly 80 percent of its daytime energy needs. This field is estimated to produce 712,000 kilowatt hours per year and was installed adjacent to the RTI campus.

The wind speed, wind direction, temperature, humidity and air pressure is monitored by the Lufft WS500 weather sensor. All sensor data are fed into a Schneider Electric BAS (Building Automation System) displaying them on the customer’s energy management dashboard.

Evergreen Solar was the responsible for the installation with oversight from Schneider Electric.
