British consulting company Dulas’ remote renewable energy survey service RRESS assesses a site’s suitability for renewable energy projects, essentially providing public sector entities with what’s described as a ‘pre-feasibility report’ that analyses the potential for new developments. The service uses light detection and ranging – LiDAR* surveys and geographic information system GIS** mapping, with all work conducted remotely. This, Dulas said, stands to save public sector organisations time and costs usually incurred via multiple site visits. “By employing cutting-edge technologies such as LiDAR and GIS, and working in partnership with local authorities to understand their ambitions and objectives, we offer a sophisticated, reliable and cost-efficient means of assessing the potential for all forms of renewable energy – including solar energy,” said Ruth Chapman, Head of Consultancy at Dulas. The service was most recently taken up by the University of Chester’s Faculty of Science and Engineering. Dulas’ RRESS assessed a 66-acre area and selected a number of suitable roof spaces and car parking sites which could be a good fit for solar installations, accounting for the orientation and slope of roofing and forecasted irradiance levels.
As a result of the survey, the University of Chester received a pre-feasibility report which stated that the installs could supply 20% of the site’s entire energy demand, and at commercially-attractive rates of return.
Dulas has pointed towards the Solar Trade Association’s recent ‘Leading Lights’ report, which examined how local authorities are now leading the way in terms of solar deployment and are ideally placed to continue that trend.
* LiDAR is a surveying method that measures distance to a target by illuminating the target with pulsed laser light and measuring the reflected pulses with a sensor. Differences in laser return times and wavelengths can then be used to make digital 3-D representations of the target.
** GIS (a geographic information system ) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data.
Reports about optimal technical and service solutions for solar energy projects will be presented at SEF 2018 KYIV.
