Solar Measurement
Our measurement campaign lasts a minimum of 12-months – our experienced service ensures accurate data collection and
continuous system performance monitoring
At Hafmex, we offer a comprehensive turnkey solar measurement service for utility-scale
photovoltaic (PV) projects. Also request site adaptation post-measurement fro your project to receive a comprehensive solar resource assessment report
Frequently Asked Questions
Do you rent out measuring devices?
Hafmex rents solar measurement systems and wind measurement equipment on a project-by-project basis. Buying systems is also a possible option depending on need and demand
Do you install customer-owned equipment?
Regarding customer-owned equipment, yes, we install, maintain, and repair customer-owned measuring devices and systems. These include Sodars, Lidars, measuring masts, solar assessment systems
and power supply systems.
For example, when it comes to Lidars, our installation process adheres to the following
standards and guidelines:
– IEC 61400-50-2 Ed.1 (2022): Wind measurement – Application of ground-mounted
remote sensing technology.
– IEA Wind RP 15: Ground-Based, Vertically-Profiling Remote Sensing for Wind
Resource Assessment (2013).
– MEASNET Evaluation of site-specific wind conditions, V3 (2022).
– Manufacturer’s guidelines: Windcube V2.1 User manual (Vaisala 2022).
Hafmex has extensive experience in operating remote sensing wind measurement devices
since 2010. Additionally, we are a Vaisala L1 certified lidar operator
Are the measuring devices provided by Hafmex calibrated?
As for calibration, all measuring devices supplied by Hafmex are calibrated. We perform
calibrations either with the device manufacturers or at accredited calibration facilities. The
calibration certificate is provided along with the measuring device.
What kind of warranty do Hafmex’s supplied measuring devices have?
For the equipment we supply, there is a 12-month material warranty for newly delivered
measuring devices and systems
Does Hafmex provide power supply systems?
Regarding power supply systems, we rent, sell, and maintain mobile hybrid systems
primarily for electrifying weather measurement stations in locations without access to the
power grid. These systems typically combine solar panels and diesel generators. Remote
monitoring and control are managed via remote connections. We also have experience
with fuel cell systems such as EFOY, and we have the capacity to monitor and perform
routine maintenance for these systems
How long does the measurement campaign last?
Generally, we recommend solar measurements lasting at least 12 months to have data for full “solar year”, preferably even
longer. This allows us to assess solar resource patterns throughout different seasons
