Commercial Solar · Why JDR

Engineering that survives the spreadsheet and the storm.

Commercial solar is a financial decision before it's anything else. The system needs to pencil out — and to do that, it has to deliver the kilowatt-hours the model assumed, for the lifetime the depreciation schedule expected. Sloppy engineering breaks both.

JDR approaches commercial PV from the operations side. We engineer for real long-term performance under Caribbean conditions: hurricane wind loading, salt-air exposure, panel-level monitoring for early fault detection, and structural attachments that won't liberate during a Category 4 event.

  • Interval-data load analysis for accurate sizing
  • Roof structural evaluation by qualified engineers
  • Rooftop, ground-mount, and carport array design
  • Net metering applications and behind-the-meter configurations
  • Three-phase inverter selection and string design
  • Production monitoring and panel-level optimization
  • PE-stamped structural attachments to PR wind code
  • LUMA interconnection coordination and witness testing
  • Construction permits across PR agencies

Every commercial project includes independent verification at commissioning — we don't trust the equipment's self-reported numbers. We measure, document, and hand off a system that performs to spec.

What's Included

Three deliverable phases, one integrated team.

01

Feasibility & Pre-construction

Interval-data analysis, structural assessment, production modeling, financial pro-forma support, and a clear engineering recommendation before any contract is signed.

02

Engineering & Permitting

PE-stamped electrical and structural designs, permit applications across PR agencies, net metering application with LUMA, and utility coordination through interconnection approval.

03

Construction & Commissioning

Self-performed installation under PE oversight or contractor management on larger projects. Independent commissioning with measured performance verification at handoff.

How We Work

Disciplined delivery at commercial scale.

Phase 01

Feasibility

Site walk, interval-data load study (when available), structural assessment, shading analysis, and a no-obligation engineering recommendation with production estimate and budget range.

Phase 02

Engineering

PE-stamped design package — electrical single-line, structural attachment plan, equipment specifications, and complete construction documents ready for permit and bid.

Phase 03

Permits & Construction

Permits submitted in parallel across all agencies. Equipment procured, installation managed under PE oversight with weekly QA reporting and milestone-based progress payments.

Phase 04

Commissioning

Independent performance testing, LUMA witness inspection, panel-level commissioning, monitoring system handoff, and a complete as-built and O&M documentation package.

Technical Standards

The codes & standards we engineer to.

Electrical Code
NEC Articles 690, 705, 706, and 710 — current edition, with attention to commercial-specific requirements (rapid shutdown, labeling, conductor sizing for higher current).
Structural
Puerto Rico Building Code and ASCE 7 hurricane wind loading. Rooftop attachments designed by qualified structural engineers; ground-mount foundations engineered to site-specific soil conditions.
Inverters & BOS
UL 1741 grid-interactive certification, IEEE 1547 interconnection. Three-phase inverters for facilities with three-phase service; module-level power electronics where shading or string mismatch matters.
Monitoring
Panel-level or string-level monitoring as a default — fault detection at the production layer, not just system-level kWh counting.
Interconnection
Net metering applications with LUMA Energy, witness testing scheduling, and three-phase service coordination handled by JDR.
Construction
OSHA 1926 compliance, qualified electrical contractor labor under PE oversight, and full QA documentation suitable for owner audit.
Common Questions

FAQ · Commercial Solar

From small commercial (10–50 kW) through larger commercial and light industrial (up to several hundred kW). For utility-scale projects we typically partner with specialized developers, contributing the engineering and PR-specific expertise rather than the full delivery. Reach out and we'll let you know honestly whether your project is the right fit.

Yes. We work both with owner-financed projects and with PPA or lease structures, providing the engineering and installation regardless of how the project is financed. We don't offer financing ourselves but we work alongside the financial partners you choose.

Yes — ongoing operations and maintenance is part of our offering. Routine inspections, monitoring oversight, performance audits, and corrective maintenance. We're particularly suited to O&M for systems we engineered because the as-built documentation is already complete.

At the feasibility stage we do a structural review — including drawings review where available — and engage a qualified structural engineer for the attachment design and any reinforcement. We won't proceed with a project until the structural path is clearly viable. If the roof needs work first, we'll tell you.

Commercial-scale storage is a growing part of our practice — for demand-charge management, backup power, and resilience during grid events. See our battery storage service area for details, or include it in your initial inquiry and we'll scope both together.
