In September, Spectrafy’s CEO attended Renewable Energy India (REI) Expo – India’s largest solar power exhibition, where he took part in the expo’s CEO Conclave and met with some of India’s leading PV developers to dicsuss the latest in solar spectral measurement and analysis. Richard also took the opportunity to meet with Spectrafy’s local resellers, various universities and key national institutions, including the National Institute of Solar Energy (NISE), the Solar Energy Corporation of India and the National Institute of Wind Energy, which operates India’s Solar Radiation Resource Assessment Program. See below for a photo of the SolarSIM demonstration conducted at NISE, in Delhi.
In June, Spectrafy had the pleasure of presenting and exhibiting at the 7th World Conference of Photovoltaic Energy Conversion (WCPEC-7), held at the Hilton Waikaloa Village on the Big Island of Hawaii.
Spectrafy was on hand to share the latest in solar spectral measurement with the global academic community, including our latest software with automated spectral correcton factors and the first public demonstration of our SolarSIM-E prototype. The SolarSIM-E consists of a SolarSIM-G coupled with an automated rotating shadowband. The SolarSIM-E enables accurate measurement of global and diffuse solar spectra, from which the direct solar spectra, and various atmospheric parameters are automatically calculated. A video of the SolarSIM-E in operation is shown below.
While there, we also took the opportunity to run a short measurement campaign. A summary of the results, which include the effects of volcanic smog from the Kilueaua eruption, can be found here.
Spectrafy’s poster presented at WCPEC-7, entitled: “Real-time, efficient data acquisition of global spectral irradiance” can be found here.
In May, Spectrafy personnel attended the 10th PV Performance Modeling Workshop in Albuquerque New Mexico and presented our lastest work on enabling the SolarSIMs to automatically calculate PV spectral correction factors (SCFs). SCFs convert complex spectral data sets into intuitive times series data that can then be used in conventional PV modeling software like any other prorate/derate. Our poster on the topic, entitled “Towards routine measurement and use of solar spectral irradiance data”can be found on the PVPMC website here.
Spectrafy is proud to announce our recent publication in the Journal of Solar Energy. In collaboration with researchers at the World Radiation Centre (WRC) in Davos Switzerland and the University of Ottawa, the paper, entitled “Extensive validation of solar spectral irradiance meters at the World Radiation Centre” presents a comprehensive uncertainty analysis of the SolarSIM-D2 that further validates its ability to accurately resolve spectral and broadband DNI, atmospheric AOD and total column ozone and precipitable water vapour. The analysis is based on measurements carried out with four SolarSIM-D/D2 sensors at the WRC in 2015.
The paper can be accessed here.
Spectrafy is proud to have been accepted into the Association of Hydro-Meteorological Equipment Industry (HMEI).
HMEI is the foremost organization representing the interests of developers, manufacturers and service providers within the hydro-meteorological industry.
The Spectrafy team looks forward to participating as a member of HMEI as we broaden our presence within the hydro-meteorological industry.
Spectrafy is glad to announce the extension of the SolarSIM Research Grant Program (SSRG) through until the end of 2018. Originally designed to wrap up in December 2017, the SSRG has been highly successful in enabling researchers all over the world to access and benefit from Spectrafy’s groundbreaking SolarSIM sensors.
Therefore, Spectrafy is delighted to extend the SSRG program, to further enable innovative research within the solar and meteorological communities.
For further information of the SSRG Program see here.
Earlier this fall, Canada’s Natural Resources Ministry (NRCan) launched the world’s first real-time solar spectral network. Powered by Spectrafy’s innovative spectral sensors, and backed up by Hukseflux’s SR20 pyranometer, the network is designed to enable the most accurate analysis of the solar technologies of today, while also meeting the needs of tomorrow. See the full article here.
Today, we are proud to release the summary report for the performance validation testing carried out at NREL on the SolarSIM-G in Sept-Oct 2017. As the report shows, the two SolarSIM-G reference units performed superbly for measurement of both broadband and spectral GHI under all weather conditions. The release of the report caps a two year development process for the SolarSIM-G and highlights Spectrafy’s ongoing commitment to develop the most innovative and accurate solar sensors on the market. A copy of the report can be view here.
In September, Spectrafy personnel headed over to NREL’s Solar Radiation Research Laboratory in Golden Colorado to take part in the 2017 National Pyrheliometer Intercomparison (NPC). The NPC is an annual event, where the SRRL invites companies, researchers and government departments to bring their direct irradiance reference devices (Absolute Cavity Radiometers, pyrheliometers, SolarSIMs) for the purpose of calibrating them against the World Radiometric Reference.
With our participation at the NPC, the SolarSIM-D2 reference units continue to build a strong history of global intercomparison and calibration, following our participation in the 12th International Pyrheliometer Intercomparison in 2015 (Davos), and the 7th International Broadband and Spectral Intercomparison in 2017 (Sicily). This ongoing commitment to intercomparison ensures the sensors that we deliver to our customers are calibrated and traceable to the highest level.
While we were at NREL, we also took the opportunity to conduct some calibration and performance testing of our SolarSIM-G reference units, against NREL’s reference spectroradiometers, pyranometers, PAR sensors and UV sensors. The results look great and will be the subject of a future post!
Photos from the 2017 NPC, including shots of the SolarSIM-D2 and SolarSIM-G can be found at: www.flicker.com/photos/srrl/sets/72157687041235443/
Earlier this month, we participated in the 7th International Broadband and Spectral Intercomparison (ISRC), held at ENEL’s facility in Catania, Italy. Organised by the European Joint Research Council (JRC), the goal of the ISRC is to disseminate best practices in the measurement and calibration for solar spectral and broadband irradiance. Our CTO Viktar Tatsiankou drew the ‘short-straw’ of spending a week in June under the Sicilian sun and was particularly excited because the 7th ISRC represented the first intercomparison we have undertaken with the SolarSIM-G. We took two SolarSIM-D2 reference units and one SolarSIM-G to Sicily. One of our European customers was also present with their SolarSIM-D2. Both the SolarSIM-D2s and the SolarSIM-G performed superbly and a summary of the results can be viewed here. Also, check out the Euronews segment on the ISRC. Viktar can be seen working hard at 1:35.
