The renewable energy industry in California has a quality control problem. A significant number of solar “companies” are, in practice, sales organizations. They sell a project, outsource the engineering to the lowest-cost design firm, and hire a patchwork of local subcontractors to install it. The company whose name is on the proposal may never set foot on the job site.
For a homeowner installing a simple rooftop array, this fragmented model might be tolerable. For a general contractor building a multi-million-dollar commercial facility, it is a liability.
The fragmentation problem
When a solar subcontractor outsources their engineering, the design team has no context for the construction environment. They don’t know the structural engineer’s concerns, they haven’t walked the roof, and they aren’t coordinating with the electrical contractor on conduit routing. When the outsourced plans arrive on site and don’t align with field conditions — which happens regularly — the result is change orders, delays, and finger-pointing between parties who have never spoken to each other.
For the GC, this means schedule risk. For the building owner, it means cost overruns. For the solar subcontractor, it means — apparently — business as usual.
How we work differently
At Symmetric Energy, we keep core engineering and design in-house. Our engineers produce the structural calculations, electrical single-line diagrams, and interconnection documents. The same team that designs the system coordinates directly with the GC’s project manager, structural engineer, and electrical contractor throughout construction.
Single point of accountability
When a GC brings us onto a project, they get one partner who owns the entire scope — from engineering through installation through utility interconnection. If something needs to change in the field, the engineer who designed it is a phone call away, not buried three layers deep in a subcontractor chain.
We conduct our own structural reviews to ensure roof loading and attachment methods meet the structural engineer’s requirements. We handle the complex utility interconnection applications — Rule 21 filings, single-line diagram submissions, and the back-and-forth with utility engineers that can stall a project for months if mishandled. And we manage installation with our own quality-controlled field teams who understand the standards we hold ourselves to.
Why this matters for your project timeline
The most expensive risk on a commercial construction project is schedule delay. Every week of slippage costs the owner in carrying costs, delayed occupancy revenue, and contractor overhead. Solar integration is one of the most common sources of late-stage construction delays — not because the technology is complex, but because the typical delivery model is fragmented.
By keeping engineering, permitting, utility coordination, and installation under one roof, we compress timelines and eliminate the coordination gaps that cause delays. When we commit to a date, we control every variable that determines whether we hit it.
We don’t just want to be a vendor on your project. We want to be the subcontractor you never have to worry about.
