Observe & Thrive: Science at the Summit

Admin — Tue, 18 Feb 2025 05:00:00 GMT

MENDOZA, Argentina – February 18, 2025 – A team of international scientists has successfully installed a high-altitude weather station just meters below the summit of Aconcagua (22,769 feet / 6,940 meters), the tallest mountain in the Western and Southern Hemispheres. This summit station completes a network of five new observation sites on the mountain, delivering vital data on water availability in the Central Andes—a region grappling with a 15-year mega-drought and historically under-monitored despite its importance as a water tower for Argentina.

Building an Effective Meteorological Station for Solar PV

Admin — Mon, 15 Aug 2022 04:00:00 GMT

Weather conditions have a huge influence on photovoltaic output. Even intermittent cloud cover can have a dramatic effect on incident solar energy, while other factors like air temperature, wind direction and speed, precipitation, humidity and air pressure can all influence the efficiency of solar cells. Monitoring weather conditions accurately is crucial in order to understand variations in PV plant performance.

Why monitor weather parameters?

While variations in weather conditions may be of only passing concern to the average domestic PV user, they are of critical importance for commercial and industrial PV systems.

For large installations, even small relative fluctuations in performance can make a huge difference to overall productivity, and any source of output variation must be closely monitored to ensure the overall system is performing optimally. In these cases, meteorological monitoring is essential in order to determine whether variations in output are due to weather conditions, or indicative of more serious hardware degradation or malfunction.

Weather monitoring is, therefore, an essential part of understanding PV system health and scheduling maintenance on time. Analysis of historical data – on precipitation and wind conditions, for example – enables seasonal trends to be uncovered, which can in turn be used to optimize cleaning and maintenance schedules on a seasonal basis.

Ice-nucleating particles influence the formation of ice crystals in clouds and many precipitation types. This study reports unique properties of ice-nucleating particles from 42 precipitation samples in the Texas Panhandle region from June 2018 to July 2019.

Hot topics in monitoring solar irradiance

Admin — Fri, 01 Feb 2019 05:00:00 GMT

We have a lot of contacts with existing and prospective customers in the solar energy industry - at exhibitions, in workshops, by email and through the Kipp & Zonen support system. Many of the same issues keep coming up, in one form or another.

So, we have decided to put together a whitepaper that addresses the most common requests for information and explanation. This is particularly topical because there is a lot of confusion resulting from recent changes in key international standards.

The whitepaper starts by explaining what is meant by solar radiation and its properties and how the various components arriving at the earth’s surface are related and affected by the atmosphere and sky conditions.

Kipp & Zonen Pyranometers, is an 11 better than a 10? You decide.

Admin — Thu, 01 Nov 2018 04:00:00 GMT

Historically, Kipp & Zonen pyranometers with a higher model number have better specifications and a lower measurement uncertainty.

As a result, there has been some confusion in the market, and the impression that the CMP10 and Smart SMP10 models are in some way inferior to their CMP11 and SMP11 cousins.

In fact this is not true. If you look at the brochure for our pyranometer range you will find that CMP10 and CMP11 share the same column in the CMP model range specification table, as do the SMP10 and SMP11 modesl in the SMP range table.
