Rooftop and ground-mount photovoltaic arrays for businesses, facilities, and institutional clients across Puerto Rico and the USVI. Sized to your daytime load profile, structurally engineered to Caribbean wind code, and delivered with net metering and full PE oversight.
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.
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.
Interval-data analysis, structural assessment, production modeling, financial pro-forma support, and a clear engineering recommendation before any contract is signed.
PE-stamped electrical and structural designs, permit applications across PR agencies, net metering application with LUMA, and utility coordination through interconnection approval.
Self-performed installation under PE oversight or contractor management on larger projects. Independent commissioning with measured performance verification at handoff.
Site walk, interval-data load study (when available), structural assessment, shading analysis, and a no-obligation engineering recommendation with production estimate and budget range.
PE-stamped design package — electrical single-line, structural attachment plan, equipment specifications, and complete construction documents ready for permit and bid.
Permits submitted in parallel across all agencies. Equipment procured, installation managed under PE oversight with weekly QA reporting and milestone-based progress payments.
Independent performance testing, LUMA witness inspection, panel-level commissioning, monitoring system handoff, and a complete as-built and O&M documentation package.
ASCE 7 hurricane wind loading. Rooftop attachments designed by qualified structural engineers; ground-mount foundations engineered to site-specific soil conditions.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.OSHA 1926 compliance, qualified electrical contractor labor under PE oversight, and full QA documentation suitable for owner audit.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.
Send us the basics — site location, approximate building size, average monthly consumption — and we'll respond within one business day with next steps, including whether a free feasibility visit makes sense.
