Stellenbosch University new spin off solar company - GeoSUN Africa

...The CRSES evaluated a number of satellite derived data suppliers by comparing their data to ground measured data and found the SolarGIS to be of exceptional accuracy, especially on DNI (Direct Normal Irradiance) values. This led to GeoSUN Africa’s current formal relationship with GeoModel Solar. GeoSUN Africa also has the exclusive right to market the SolarGIS products in Southern Africa. GeoSUN Africa maintains a close and formal tie with the University of Stellenbosch, specifically the Centre for Renewable and Sustainable Energy Studies (CRSES)...

Solar Radiation - User Cases

MACC-II has been providing aerosol forecasts to GeoModel Solar, a company specialised in site qualification, planning, financing and operation of solar energy systems. Aerosols directly affect the amount of solar radiation reaching the Earth's surface and therefore are one of the components determining the amount of solar radiation available for solar energy purposes at any one location on theEarth.

Solar software challenge: Making solar databases accessible

...One such newcomer is Slovakia-based GeoModel Solar, a developer and operator of what the recent IEA SHC Task 36 data inter-comparison activity called 'the best performing solar radiation database presently available on the market'. The major strenghts of the database, known as SolarGIS, are the balanced statistical representation of the values (histograms), very good accuracy in GHI and excellent accuracy in DNI.

Planning and monitoring

GeoModel Solar from Slovakia, a provider of solar data and operational PV services, will launch pvSpot, a new monitoring concept. PvSpot is an online tool that offers yield-to-yield comparison instead of yield-to-irradiance comparison. The energy yield for any PV system can be calculated using real-time solar radiation data from the SolarGIS database. Read more on page 152 »

GeoModel Solar’s latest software suite quickly
and accurately plots a PV project’s potential

GeoModel Solar has launched a new generation of solar installation software - iMaps and pvPlanner that is claimed to offer a new standard to the PV industry. iMaps provide access to key solar resource parameters with a spatial detail of 250 meters, thus allowing for accurate site selection while pvPlanner allows fast comparison of various sites and technology options.
PV project developers require quick and easily identified project sites that have high insulation to maximise electricity production and ensure the economic profitability of solar energy projects. Engineers, installers, financers, policy-makers and wider community need to be able to use reliable, historical and up-to-date information before investments are made. Read more >>

DNI: Measuring bang for your buck

What happened at Shams 1 would nowadays probably be classified as a schoolboy error. Last year, the CSP plant’s owner, Masdar, confessed that it had overestimated how much sunlight would reach the parabolic trough field. It had not factored in the amount of dust in the air.
"The Shams original estimate was based on satellite data and was off by more than 10%," says Marcel Suri, managing director of GeoModel Solar, a solar resource consultancy... Read more >>
