PANEL LAYOUT OPTIMIZATION

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.  

SHADOW ANALYSIS

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.

 

Structural Engineering

We offer in-house structural engineering services for both residential and commercial projects.

RESIDENTIAL

For residential projects, we do the structural assessment after the array is planned out, so we determine if the roof can support the array. Local loading conditions like snow, wind, and seismic activity are included in the analysis.

Commercial

For commercial projects, we do the assessment before the array is planned out, so we first determine how much additional loading the structure can support (which can be much greater a standard array). After the array is planned out, we do a second review for the array specifically. Local loading conditions like snow, wind, and seismic activity are included in the analysis.

Our structural engineers can also provide ballasting reviews and HVAC structural assessments.

 

Electrical Engineering

Our in-house electrical engineering services include single-line diagrams for solar panel layouts and interconnection details for residential and commercial solar PV installations.

Our site technicians gather all necessary electrical data on the same site visit as the initial rooftop measurement and survey. Our design and engineering team will then create an electrical layout for submission to the permitting office. We consider installation costs and other potential problems when designing the layout to create the best possible solution. All of our electrical layouts are then stamped by our certified professional engineer.
