Sky Cam Vision<\/b> methodology<\/h2>\n<\/div><\/div><\/div>

The Sky Cam Vision<\/b> instrument <\/span>comprises a visible fisheye camera looking at the sky, providing a full sky coverage, equivalent to a 180\u00b0 field-of-view. The Sky Cam Vision is designed to be dust-tight. Thus, it resists liquid ingress<\/span> thanks to a <\/span>weatherproof aluminum-sealed housing.<\/span>\u00a0<\/span><\/p>\n

It is equipped with a mini-PC to locally process the images it takes. When it is located on a site with a poor internet connection, it needs to be coupled with Reuniwatt\u2019s Sky Companion. This is a local server which is integrated in the project\u2019s server room.<\/span>\u00a0<\/span><\/p>\n

As an option, it is possible to add a<\/span>global horizontal irradiance (GHI) sensor. <\/span>\u00a0<\/span><\/p>\n

The equipment is suitable for harsh climatic conditions and withstands temperatures from -20\u00b0C to +50\u00b0C. As a complementary solution to\u202f<\/span>Sky InSight™<\/span><\/b><\/a>, some of Sky Cam Vision<\/b>\u2019s software services have been specifically developed to get the most of its cloud imaging capability for cloud studies or solar forecasting applications. Moreover, solar irradiance forecasts are provided through Reuniwatt\u2019s InstaCast™<\/a><\/strong> service. InstaCast™ combines image processing with machine learning techniques to guarantee the best adaption to the site\u2019s specific conditions. The forecasts can be computed locally and sent to the SCADA or power plant controller via Modbus, for integration into the plant\u2019s control scheme \u2013 completely offline, if necessary, to serve even the most remote projects.<\/span><\/p>\n
