Solar that sits on a roof engineered to carry it.
HechosHH LLC provides structural solar engineering—roof capacity review, racking attachment design, and PE-stamped drawings—so your array is safe, permit-ready, and coordinated with how the building works.

Clean arrays start with clear structural engineering—not field improvisation.
Why solar needs structural engineering
Panels and racking change how a roof carries load. Strong solar engineering protects the structure, the warranty path, and the approval process—before the first module is set.
The roof must carry the array
Solar adds dead load, wind uplift, and concentrated attachment forces. We verify the existing structure can support the system—or design the reinforcement it needs.
Attachments that stay sealed and secure
Racking layout, standoffs, and connection details are engineered for your roof type—shingle, metal, or membrane—so installers have a clear, code-ready path.
Documentation that clears review
Permit offices and utilities often require PE-stamped structural drawings for solar. We deliver packages that move approvals forward without guesswork.
From roof assessment to sealed install drawings
Our solar process moves from existing conditions to coordinated structural documentation—clear for installers, reviewers, and owners alike.
01 · Site & roof
Assess existing conditions
Evaluate roof framing, covering, orientation, and constraints so the array design respects how the building already works.
02 · Layout
Coordinate the array
Align module layout with structural capacity, setbacks, and access—so performance goals and constructability stay in balance.
03 · Attachment
Engineer the connections
Design racking attachments for metal, shingle, or other roof types—with clear details for wind, uplift, and waterproofing coordination.
04 · Systems
Align structure with MEP
Coordinate structural support with electrical and mechanical routing where inverters, conduits, and roof penetrations affect the design.
How a solar engineering engagement works
- 01
Share project details
Roof photos, existing plans, proposed array layout, or installer drawings—we clarify structural scope and jurisdiction requirements quickly.
- 02
Review roof capacity
We analyze framing, spans, and load path under solar dead load and wind uplift so the installation is safe for the life of the system.
- 03
Design attachments & reinforcement
Where capacity is short, we engineer sistering, beams, or attachment patterns that keep the roof and array working as one system.
- 04
Issue PE-stamped drawings
You receive clear structural plans and details suitable for permitting, installer coordination, and field execution.
- 05
Support through approval and install
Plan-check comments or field questions? We remain available so the solar project stays aligned with the sealed design.
Energy goals deserve structural certainty.
A successful solar project is more than module count. It is a roof that can carry the load, attachments detailed for the covering, and stamped drawings your installer and permit office can trust. That is the standard we deliver.
