Solar CAD Detailing- Procedure

INPUTS

A typical set of inputs we need from the client includes:

Hand sketch/Photograph of targeted roof along with the existing protuberances and shading
Scaling factor of the above image
Brand, model number and submittals of the panel to be used
Rafter arrangement with spacing
Locations of existing utility meter

Locate the building and obtain the image of the building using Google Earth.

Place the panel on the roof plan with the identified slope by avoiding protuberances and shadows of objects.
Show the attachments and mounts of the panel to the rafters.
Plot the electrical connections to the panel with the cable to be used and the junction box.
Plot the inter-connections to the support elements, inverter and solar power meter.
Prepare a single line diagram of panel arrays with the associated electrical elements and appropriate cables.

Using the given template, we prepare a set of pdf sheets as deliverables embedding the following:

Site plan & vicinity map

Google Earth 3D image of the building, panel location on roof, make, model and number of solar panels with dimensions

Roof plan & panel connection details

Roof attachment details & electrical equipment location

Elevation of the building showing the solar power & utility meters along with other protuberances that are present

Electrical line diagram

Electrical single-line diagram depicting the connections between all electrical elements
