| Zusammenfassung |
The fast development of solar radiation and energy applications, such as
photovoltaic and solar thermodynamic systems, has increased the need for
solar radiation measurement and monitoring, for not only the global
but also the diffuse and direct components. End users look for the best
compromise between getting close to state-of-the-art measurements and
keeping low capital, maintenance and operating costs. Among the existing
commercial options, SPN1 is a relatively low cost solar radiometer that
estimates global and diffuse solar irradiances from seven thermopile sensors
under a shading mask and without moving parts.
This work presents a comprehensive study of SPN1 accuracy and sources of
uncertainty, drawing on laboratory experiments, numerical modelling
and comparison studies between measurements from this sensor and
state-of-the art instruments for six diverse sites. Several clues are
provided for improving the SPN1 accuracy and agreement with state-of-the art
measurements. |
