Our drone and 3D modelling technology captures the height and location of all obstructions on and off the rooftop, which our designers translate into a dimensionally accurate roof drawing and panel layout. The panel layout is optimized based on a variety of factors, including the shadow analysis and local building and fire codes.  


Exactus has the technology to simulate where shadows will occur at any time of day, time of year, and in any geographic location. We make sure that our clients’ installation sites receive the optimal amount of sunlight all year long.
