Solar Estimation


MacSolar E Insolation Meter (economy version)

Product code: SOL-MAC (E)


This hand-held solar measuring device is useful for checking the output of PV systems. Simply put in the sun and take a reading! It combines a sensor for measuring global radiation (W/m²), a sensor for measuring temperature, a display and operation unit and a solar power supply in a weather proof casing. This basic version permits measuring the current light intensity and temperature. Data Sheet






MacSolar (full version)

Product code: SOL-MAC
The same combination as above but with an additional computer-assisted simulator for photovoltaic modules and a mounting fixture for wall or roof.  By measuring the current light intensity and temperature, typical characteristics of solar plants are simulated by the integrated computer. An exact yield check can be carried out very quickly and can be performed over any period of time by registering average values.  The data logger allows data to be stored in the internal memory.  Data Sheet

An optional software package is available.

Handheld Solar Horizon EstimatorHandheld Solar Horizon Estimator

Product code: SOL-EST

This enables the potential effect of shading by trees or buildings to be gauged and is useful for a pre-installation site assessment.

Simply stand at the proposed PV array site and orientate it towards the South to view obstacles to sunlight.


Includes compass and laminates to show sun paths at different times of the year.
