Products & Services

Meteotest

Meteotest is the company behind the product Meteonorm.

Meteotest

Meteotest was founded 1981 as an independent private company. Our team consists of approximately 40 scientists, engineers and software developers.

Meteotest is committed to ecological issues and a sound working environment since it was founded. The majority of the company is owned by the employees. This aspect is a guarantee for the long term successful strategy of our company as well as a high dedication towards our clients.

In this environment, the first version of Meteonorm was created in the early 80ies thanks to intensive research activities in collaboration with universities and the industry. Since then Meteonorm has been continously developed. Today it is considered as an industry reference for solar resources and is successfully used worldwide.

Meteonorm Software

Meteonorm is a comprehensive meteorological reference data base. It gives you access to a catalogue of meteorological data for solar applications and system design at any desired location in the world. It is based on more than 25 years of experience in the development of meteorological databases for energy applications. Meteonorm addresses engineers, planners, investors, architects, teachers and anyone interested in solar energy and climatology.

Measurement Archive

The measurement archive contains historical, unaltered data from meteorological stations or satellites out of our Meteonorm archive.


Meteorological stations

The measurement archive contains a selection of monthly mean values of a meteorological station. Archives are only available for the locations of measurement stations (no interpolations).

Satellites

For better coverage, you can order a measurement archive of the satellite data contained in Meteonorm.

Order process

After your order, we will check the availability of the specified time period and parameters. The order will only be carried out after your reconfirmation.

Dataset

A Meteonorm dataset is the right choice if you require location specific meteorological data once or occasionally for your assessments or calculations.


Typical year

A Meteonorm dataset contains values of the required weather parameters for a typical year in the selected time intervall (minute, 10-minute, hourly or daily values). The typical year corresponds to the long term mean and is therefore the reference for assessments and planning purposes.

Horicatcher

With the Horicatcher you can digitize the local horizon and shadowing situation efficiently and precisely. Import the horizon into Meteonorm for even more precise results.

From the horizon data, Meteonorm calculates limitations of the sunshine duration and irradiation due to obstacles. The result can be analyzed directly in the field.

Horizon Analysis in Seconds

The Horicatcher tool within the Meteonorm software calculates the sun's orbit, which is put in relation with the horizon. Meteonorm takes into account the reduced solar energy input, the sunshine duration and sun exposure.

Using meteonorm horicatcher, Meteotest also provides individual sunshine exposure analyses. Aus us for a quote!

Components

A horizon mirror, the camera and the mounting device are attached to a regular photographic tripod. The built-in circular level allows a precise leveling of the device. The following components are included in the delivery:

  • digital camera
  • camera mounting device and horizon mirror
  • new: analysis software included in the meteonorm software (Version 7)

Map

We produce maps with any meteorological parameter for any region in the world between 62° S and 62° N.

Meteonorm maps are based on the Meteonorm database and the Meteonorm interpolation algorithms. As each map point is calculated separately, the production of a Meteonorm map requires a lot of computing power.

Direct normal (beam) radiation as well as global radiation maps are the most requested ones. However, we can produce maps for virtually any meteorological parameter.

Available resolutions

  • low resolution: 30 km
  • high resolution: 3 km (nur Europe)
  • very high resolution: 0.1–1 km

Additional information

  • standard format: PNG
  • very high resolution: max. 50'000 data points (horizon taken into consideration)
  • Price for maps with more than 50'000 data points upon request
  • Prices can be altered without notice
  • Surcharge for rastered formats: EUR 100

Expertise

Our expertises are individually customized assessments of the solar irradiation at your project site and for your specific requirements.

Our experts analyse all available data sources and provide you with a trustworthy and independent first or second opinion on the solar irradiation.

Additional data sources

An expertise is the ideal supplement to the Meteonorm software. It takes external data sources into account which are not available through the software.

Usually, our expertises contain information on the following topics:

  • Solar irradiation (Gh, DNI)
  • Data quality
  • Distance to weather stations
  • Variability, trends
  • Uncertainty
  • Exceedance probability (P90/P10)
  • Climate change (IPCC scenarios)

Uncertainty analysis

An expertise contains a detailed analysis of the uncertainty of the solar assessment. The uncertainty mainly depends on the number and the quality of weather stations available in the vicinity of your site. Different data sources – including different satellite data – are compared and taken into account.

Build on our experience

Our expertise gives you access to 25 years of experience in solar resource assessment.

Solar Cadaster

A solar cadaster is an inventory of each roof in a town, commune or region, its orientation, inclination and irradiation as well as the corresponding solar potential.


Based on Meteonorm

In collaboration with our GIS department, we offer solar cadasters for towns, communes and regions based high resolution digital terrain models a 3D town model. For each point on every roof, we calculate local shadowing (trees, neighboring buildings) as well as the topographic horizon. The terrain model's high resolution even allows taking complex roof structures into account. The irradiation data is calculated for each roof surface separately.

Benefits

Our solar cadasters can be utilized to assess a town's or region's potential for the production of solar power. Additionally, the data can be combined with additional information, e.g. protected historical buildings, in order to further refine the potential analysis. Furthermore, a yearly solar power production can be calculated for single houses and even single roof areas.

Planning and communication tool

This information can be used internally (authorities, power companies) or published in a web application in order to sensitize house owners and citizens.
