For Japan
- Japan is comprised of over 70% mountainous terrain. This leaves the little space for clusters of solar plants on undulating and mountainous terrain. Sunpulse has developed 3D-terrain and digital elevation model technology to address the problem of sloped terrains. In many cases, modules of differing azimuth and placed onto varied terrain to optimize space. In yield reporting technology, special methodologies are required to accurately predict the yield output of a solar plant.
- Due to the geographic nature of the island archipelago of Japan, microclimates exist. This means that one side of a mountain has a different snow profile and/or climate compared to the other side of a mountain. Sunpulse has developed an advanced snow model to predict snowfall in many microclimates. Also Sunpulse has developed advanced irradiance pre-screening technology to predict solar irradiance referencing multiple datasets.
The framework is based on the JIS C 8907:2005 Japanese industrial standard for energy yield analysis and also has the additional input of multiple irradiance data sources to strengthen correlation. Final specific yield assessment is based on the Meteonorm 8 dataset.
