Solar Drafting Services in Colombia 2026: A Complete Guide for Solar Professionals

Colombia’s solar market is moving fast. The country reached roughly 3 GW of solar capacity in early 2026, split between 1,600 MW in commercial operation and another 1,400 MW in testing, according to UPME and Energía Estratégica reporting. The May 2026 firm-energy auction added another 1,546.9 MW of solar for delivery between 2029 and 2030, and distributed generation keeps growing at 30% or more per year in cities like Bogotá, Medellín, and Calli.

That growth creates a bottleneck that is easy to ignore until it costs a project: technical drawings. Someone has to produce the single-line diagram, the array layout, the equipment schedule, and the permit set that makes a project legal and bankable. In Colombia, that work is governed by a new RETIE regulation that took effect on January 1, 2026, plus CREG net-billing rules and XM grid-connection requirements.

This guide explains what solar drafting services in Colombia actually deliver, what they cost, how the 2026 regulatory changes affect your drawings, and when it makes sense to hire a drafter, build an in-house team, or use solar design software.

In this guide you will learn:

• What solar drafting services in Colombia actually deliver
• How the 2026 RETIE update changes drawing requirements
• Typical pricing and timelines for residential, commercial, and utility-scale projects
• The main Colombian regulations and authorities that review your documentation
• How to choose between a local drafting firm, an offshore service, and solar design software
• Common mistakes that delay permits and interconnection approvals

What Are Solar Drafting Services in Colombia?

Solar drafting services in Colombia are technical providers, usually staffed by an electrical engineer, technician, or qualified designer, who produce the drawings and documentation required to permit, finance, and connect a photovoltaic system to the Colombian grid.

Their work sits between site sales and construction. A salesperson closes a deal with a homeowner in Cali or a commercial client in Bogotá. The drafting service turns that contract into a set of plans that the local municipality, the grid operator, and the financier can review.

Who Provides Solar Drafting in Colombia

The market has three main types of providers:

1. Local engineering consultancies. Firms like VQ Ingeniería in Bogotá offer renewable energy consulting, conceptual and detailed engineering, and ready-to-build packages. These teams understand Colombian regulations and can sign off on technical documentation.
2. Solar EPCs with in-house design. Companies such as Edemco, Suncol Energy, PT Ingeniería de Proyectos, Energitel, and Ecosolar Colombia often bundle drafting with installation. This works well when the same team designs and builds the project.
3. Offshore drafting specialists. Providers like Microdras and VS Solar Service advertise solar drafting across North and South America, including Colombia. They typically charge less but need local review for RETIE and CREG compliance.

What Makes Colombian Solar Drafting Different

Colombian solar drafting is not generic CAD work. Three factors make it distinct:

• RETIE 2024 is now mandatory. Resolution 40117:2024 replaced Resolution 90708:2013 on January 1, 2026. Drawings must now reflect the updated safety, labeling, and equipment requirements.
• CREG net-billing adds a documentation layer. Distributed generation systems need paperwork that supports Resolution 030/2018 registration, including the single-line diagram and the legalization act.
• Utility-scale projects need XM grid studies. Large projects must comply with the XM Código de Redes, which requires specific modeling and interconnection studies that go far beyond a standard permit set.

Why Solar Drafting Matters in Colombia’s 2026 Market

The numbers explain the pressure. Colombia’s solar pipeline is large enough that small delays in design become big problems in construction.

For installers, this means two things. First, permitting offices and grid operators are busier, so incomplete drawings are rejected more often. Second, competition is rising, and the companies that produce accurate documents faster win more projects.

A residential installer in Medellín might lose a week if a single-line diagram is missing the inverter model number. A utility-scale developer can lose a month if an XM interconnection study uses the wrong grid model. Good drafting is not a back-office task. It is a project-risk tool.

Colombian Regulations and Standards for Solar Drafting

Solar drafting in Colombia does not happen in a regulatory vacuum. Several rules and agencies govern every drawing.

RETIE 2024: The New Baseline

The Reglamento Técnico de Instalaciones Eléctricas (RETIE) is Colombia’s mandatory technical regulation for electrical installations. Resolution 40117:2024 entered into force on January 1, 2026, replacing Resolution 90708:2013.

For solar drafters, the practical impact is:

• Equipment must be listed or certified under the new RETIE scope, including inverters, modules, and energy storage systems.
• Labels, disconnects, and grounding details must match the updated requirements.
• The legalization act, signed by a qualified professional, must reference the correct RETIE resolution.

NTC 2050 and Article 690

NTC 2050 is the Colombian adaptation of the U.S. National Electrical Code. Article 690 covers solar photovoltaic systems. While NTC 2050 is not mandatory by itself in the same way RETIE is, it provides the technical “how-to” that most Colombian engineers follow. Drafters should size conductors, overcurrent protection, and grounding in line with Article 690.

CREG Resolution 030/2018

The Comisión de Regulación de Energía y Gas (CREG) issued Resolution 030/2018 to create autogeneración a pequeña escala (AGPE), Colombia’s net-billing framework. Systems up to 1 MW can qualify, with simplified interconnection for systems under 100 kW.

Drafting services support this process by providing:

• The single-line diagram submitted to the grid operator
• The equipment schedule that proves inverter capacity
• Documentation for the legalization act that activates net billing

XM Código de Redes

For utility-scale projects, the Código de Redes administered by XM sets the rules for connecting to Colombia’s national interconnected system (SIN). This includes power-flow studies, short-circuit studies, stability analysis, and reactive-power requirements. These studies are not drafting in the narrow sense, but they depend on the same project data and often come from the same engineering team.

Solar Drafting vs. Solar Design Software in Colombia

Colombian solar professionals face a choice: hire a drafting service, buy solar design software, or combine both. The right answer depends on project volume and complexity.

The hybrid model is becoming standard in Colombia. Software handles layout, shading, and initial electrical design. A local drafter or engineer then reviews the output, adds RETIE-specific details, and signs the legalization act.

SurgePV’s solar design software can generate layout and electrical documentation quickly, while the solar proposals and generation and financial tool help installers present CREG-compatible payback numbers to clients.

Solar Drafting Cost in Colombia: 2026 Pricing Guide

Pricing for solar drafting services in Colombia depends on project size, complexity, and whether the provider is local or offshore.

Offshore providers like Microdras advertise residential drafting from $35 per project. That price usually covers a basic permit set and may not include local code review, RETIE legalization support, or revisions. For Colombian installers, the real cost often includes a local engineer’s review before submission.

Top Solar Drafting Service Providers and Software Options in Colombia

The following table lists representative options. Always verify current capabilities, certifications, and references before hiring.

How to Choose a Solar Drafting Service Provider in Colombia

Use this decision framework:

1. Check RETIE familiarity. Ask how many projects the provider has completed under Resolution 40117:2024. The new regulation changes labeling and equipment requirements.
2. Verify CREG 030/2018 experience. If the project is grid-tied and under 1 MW, the drafter should understand net-billing documentation.
3. Confirm sign-off authority. For the legalization act, you typically need a qualified Colombian electrical or mechanical engineer.
4. Review sample deliverables. Ask for a redacted permit set from a similar project. Check that single-line diagrams, equipment schedules, and structural notes are complete.
5. Clarify revision policy. Some offshore services charge per revision. Local firms may include one or two rounds.
6. Match software to workflow. If you use solar design software, ask whether the drafter can accept PDF, DWG, or DXF exports and adapt them to local standards.

Common Mistakes When Outsourcing Solar Drafting in Colombia

• Skipping the RETIE 2024 check. A drawing based on the old RETIE can be rejected during legalization.
• Using generic U.S. or European templates. Colombian municipalities and grid operators expect Spanish-language documentation, local standards, and Colombian equipment listings.
• Ignoring the network operator’s requirements. Each utility may have its own interconnection application format.
• Forgetting structural verification. A roof layout that ignores tile type, rafter spacing, or wind load can fail inspection.
• Confusing design with engineering. A drafter can produce drawings, but only a qualified professional can sign the legalization act.

When to Use SurgePV for Colombian Solar Drafting

Solar drafting services in Colombia are evolving from a manual, per-project cost center into a hybrid capability that combines software automation with specialist engineering. The 2026 market demands speed, RETIE-compliant documentation, and net-billing financial modeling that most standalone drafting services do not provide.

SurgePV helps Colombian installers and EPCs in three ways:

1. Faster initial designs. Generate layout, shading, and electrical documentation in minutes instead of days.
2. Consistent output. Reduce revision cycles with standardized single-line diagrams and equipment schedules.
3. Sales-ready proposals. Combine technical drawings with CREG-compatible financial modeling so clients see payback before construction starts.

For complex utility-scale work or projects that need a Colombian professional’s stamp, pair SurgePV with a local engineering reviewer. For high-volume residential and commercial work, SurgePV can replace much of the repetitive drafting work entirely.

Conclusion

Colombia’s solar market is growing across all segments, from rooftop systems in Bogotá to utility-scale parks in La Guajira. That growth makes solar drafting services more important, not less. Accurate, regulation-ready drawings are the difference between a project that connects on time and one that sits in a permitting queue.

In 2026, the key changes are the mandatory RETIE 2024 update and the continued expansion of CREG net-billing. Installers and developers should choose drafting partners who understand both, and they should consider software automation for the repetitive parts of the workflow.

Three actions to take now:

• Audit your current drawings against RETIE Resolution 40117:2024.
• Build a shortlist of Colombian drafting providers or software tools that can produce CREG-compatible documentation.
• Test a hybrid workflow where software generates the first draft and a local engineer reviews and signs off.

Frequently Asked Questions

What are solar drafting services in Colombia?

Solar drafting services in Colombia are technical providers that create RETIE-compliant electrical schematics, single-line diagrams, array layout plans, and grid-connection documentation for photovoltaic systems. They are usually staffed by electrical engineers or technicians who understand Colombian standards like NTC 2050 and regulations from CREG, UPME, and XM.

How much do solar drafting services cost in Colombia?

Residential solar drafting in Colombia typically costs $150-$600 per project, commercial systems run $500-$2,500, and utility-scale projects start around $3,000 and scale with complexity. Offshore drafting shops may advertise from $35 per project, but local engineering review and RETIE legalization usually add cost.

What deliverables should I expect from a Colombian solar drafting service?

Expect a site plan, roof or terrain layout, single-line diagram, stringing diagram, equipment schedule, bill of materials, conduit and wire sizing, structural notes, and a permit set. For grid-tied systems the package should also support CREG Resolution 030/2018 net-billing registration and the RETIE legalization act.

How long does solar drafting take in Colombia?

A standard residential project takes 2-5 business days once site data is complete. Commercial projects take 1-2 weeks. Utility-scale or projects needing an XM interconnection study can take 4-8 weeks or longer depending on the network operator’s queue.

Which Colombian authorities review solar drafting documentation?

The grid operator or utility reviews interconnection documentation under CREG and XM rules. The local municipality reviews construction and electrical permits. A qualified professional must sign the RETIE legalization act, which is required for commissioning and net-billing activation.

What is the difference between solar drafting and solar design software?

Solar drafting services produce manual technical drawings, usually in AutoCAD, for a per-project fee. Solar design software automates layout, shading, electrical design, and financial modeling through a subscription. In Colombia, the key difference is RETIE-ready documentation: some software generates compliant single-line diagrams instantly, while manual drafters charge separately for each revision.
