Practical quick checks for measurement sites, buildings, offshore activities and renewable energy. Results are indicative and help identify the right follow-up questions.
Calculate the distance of an obstacle from a wind sensor relative to its height above the sensor.
A larger D/H ratio is generally more favourable. Actual influence also depends on width, shape, sector, terrain roughness and prevailing wind direction. This quick check is not a WMO classification.
Calculate dew point, absolute humidity and the margin to a surface temperature.
If a surface is colder than the dew point, condensation may occur. Coating work often uses a minimum surface margin of 3 °C above dew point; always verify the product specification and actual conditions.
Estimate power from irradiance, solar elevation, panel tilt, orientation and system properties.
The tool uses a simplified incidence-angle correction and a general diffuse component. Shading, temperature, inverter clipping, soiling, cable losses and the local horizon are not fully modelled. Not suitable as a bankable yield assessment.
Calculate the kinetic power density of the wind and an indicative electrical output.
Wind power increases with the cube of wind speed. A small measurement bias from obstacles or incorrect sensor height can therefore create a much larger energy-estimate error.
Calculate absolute humidity and the theoretical amount of water vapour to remove to reach a target RH.
This is a snapshot at constant temperature. Moisture generation, ventilation, leaks, construction moisture and cold surfaces determine the actual trend. Long-term monitoring provides a much more reliable picture.
Convert a rainfall amount directly into litres of water over a selected area.
One millimetre of rainfall on one square metre equals exactly one litre of water. The collection factor provides an indicative correction for losses, splash, evaporation and disconnected surfaces.
