A New and Inexpensive Pyranometer for the Visible Spectral Range. Sensors (Basel, Switzerland), 9(6), 4615–4634. http://doi.org/10.3390/s906046151424-8220http://hdl.handle.net/10272/14239This paper presents the design, construction and testing of a new photodiode-based pyranometer for the visible spectral range (approx. 400 to 750 nm), whose principal characteristics are: accuracy, ease of connection, immunity to noise, remote programming and operation, interior temperature regulation, cosine error minimisation and all this at a very low cost, tens of times lower than that of commercial thermopile-based devices. This new photodiode-based pyranometer overcomes traditional problems in this type of device and offers similar characteristics to those of thermopile-based pyranometers and, therefore, can be used in any installation where reliable measurement of solar irradiance is necessary, especially in those where cost is a deciding factor in the choice of a meter. This new pyranometer has been registered in the Spanish Patent and Trademark Office under the number P200703162.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/calibrationdata acquisitionphotodiodepyranometersolar irradiancethermopilevisible spectral rangejournal articlehttp://doi.org/10.3390/s90604615open access
