Save time, save energy.
Solar done right.

Solar Done Right is leading the movement to advance the quality and safety of solar design and installations by having every set of solar plans reviewed using the Solar Done Right Best Practices Checklist.

Top 5 Reasons to Reject Solar Plans

1

Missing PE Stamp

The state of Florida now requires a PE Stamp, or an FSEC certification per FS 377.705(d).

2

Not Site Specific Plans

There is nothing generic about a PV system. The FBC requires that the project be site specific, and the calculations be performed for that. The site-specific components include, wind speed, exposure category and risk category. They will also include module pressures and attachment spans. These cannot be generically assumed.

3

Incorrect Wind Zones

With the adoption of FBC 2020, there came a change in the number of wind zones on the roof of a residential structure. The number of roof zones changed from 3 (Zones 1, 2 and 3) to 7 (1, 1’ , 2e, 2r, 2n, 3e and 3r). The new wind zones also bought a change to the way the roof zones are set on a flat roof. The pressures per roof zone also increased with respect to wind speed.

4

Missing Module Exposure Identification

This is the biggest change to come out of the code change. This differentiates the pressures experienced by the PV module based on its location in the array. The modules will now be separated into Edge, Exposed and Non-Exposed modules. Modules that are too close to the edge of the roof will be termed Edge modules. Modules that are more than a certain distance away from the edge of the roof will be termed exposed, and the rest will be non-exposed.

5

Incorrect Attachment Spans and Loading

The spans between attachment are determined by the loading on the attachments. The loading on the attachments should not be greater than the maximum allowable strength of the attachments. This will limit the span of the rails between the attachments.
