Learning to measure solar irradiance

One of the variables that we must check before carrying out a photovoltaic inspection with drones is the irradiance, for this we must use a solar meter like this one shown in the video. It is a device that we can buy online and is designed to measure the value of irradiance in open environments, we should not confuse the solar irradiance meter with a light meter because the measurements and the ranges that we are going to obtain are different.


To measure the irradiance before carrying out an inspection of a solar plant, we must place the equipment perpendicular to the photovoltaic panel. If the value obtained is around 400 W/m2, we are within the minimum limits. The value obtained in the video is about 200 W/m2, in this case this value of solar irradiance is not suitable for carrying out the work.


For a successful inspection (as far as irradiance values are concerned) we must have values from 600 W/m2 as stated in the IEC TS 62446-3standard.

    I have observed that in digital camera models, extraordinary receptors help to {focus|concentrate|maintain focus|target|a**** automatically. The sensors involving some cams change in contrast, while others make use of a beam involving infra-red (IR) light, specially in low light. Higher specs cameras occasionally use a mixture of both devices and might have Face Priority AF where the video camera can ‘See’ any face while focusing only on that. Thank you for sharing your thinking on this blog site.
