The document summarizes updates to HelioScope, a cloud-based solar design software. Key updates include: 1) Adding a spectral adjustment model for CdTe solar modules to account for the effects of precipitable water. 2) Developing a next generation shading engine that calculates diffuse irradiance for each module individually and improves performance. 3) Enhancing the design environment with features like an interactive 3D view, automatic string design, dual-MPPT inverters, and LiDAR integration.
