Services / Commercial Solar
Roof space that pays for itself.
Commercial rooftops and yards are usually the largest unused asset a facility owns. ZVRGE builds the electrical side of putting them to work — array through inverter, collection, interconnection and commissioning.
What this covers
- Rooftop arrays
- Ground mount
- Carport structures
- Inverters
- DC collection
- AC collection
- Interconnection
- Metering
- Monitoring
- Commissioning
- Panel removal & reset
- Storm damage & insurance claims
- Service calls
- Diagnostics & repair
Array to inverter
Module wiring, DC collection, combiners and inverters installed to the design and to the conditions a Texas roof actually sees. Workmanship on the DC side is what determines whether the array still performs the way it was modeled in year eight.
Interconnection
AC collection, protection, metering and the utility interconnection — the part of a solar project most likely to move the schedule. Utility requirements and lead times are engaged at the start, because they will not compress later.
On buildings that keep operating
Commercial arrays go on working buildings. Roof access, path of travel, penetrations coordinated with the roofer and the roof warranty, and tie-in windows that do not interrupt the tenant — the constraints that decide whether the install is smooth.
- Penetrations and attachments coordinated with the roofing contractor and warranty
- Tie-ins scheduled around occupancy and operations
- Structural and access constraints resolved before mobilization
Commissioned and monitored
Systems are tested and turned over with monitoring that actually reports — because an array that quietly underperforms costs exactly as much as one that works, and nobody notices without the data.
Panels off, roof done, panels back on
A roof reaches the end of its life while a live array sits on it. ZVRGE detaches and resets: modules brought down and labelled to the string map, the DC field isolated and locked out, attachments and flashing renewed alongside the roofing contractor, then rebuilt, re-torqued and re-commissioned — so what goes back up is the system that came down, not an approximation of it.
- Detach, label and stage modules and racking
- DC isolation, lockout and safe storage while the roof is open
- Attachments and flashings renewed with the roofing contractor
- Reset, re-torque, re-terminate and re-commission to the original string map
Storm damage, documented for the carrier
Hail and wind claims are decided on evidence, and the array is the part of a damaged roof an adjuster is least equipped to assess. We inspect it module by module, pull what the system was producing before and after, and write the repair scope in the detail a carrier needs to price it — then answer the technical questions that come back. The claim stays yours to settle; what we supply is the electrical evidence it turns on.
- Module-level and balance-of-system damage inspection
- Production evidence pulled from the monitoring record
- Repair scope and estimate written in the detail an adjuster can price
- Technical questions answered through the carrier's review
Service calls, including on arrays we did not build
Most solar service calls are not about the panels. Production drops, an inverter faults, a string goes dark, a rapid-shutdown device fails, or the monitoring simply stops reporting and nobody notices for a season. ZVRGE will diagnose and repair a system it did not install, and will tell you in writing what it found — whether or not the repair is ours to sell.
- Production and monitoring diagnostics
- String, insulation-resistance and IV-curve testing
- Inverter, optimiser and rapid-shutdown faults
- Findings written down, on any manufacturer's equipment
An array that quietly underperforms costs the same as one that works.
FAQ
Common questions
Yes — protection, metering and the interconnection application are part of the scope. On commercial solar the utility process is regularly the longest item in the schedule, so it starts at the beginning rather than after the array is built.
