Solar Drafting Services Kenya: EPRA & KPLC

Last updated: November 2026. SurgePV publishes this post and sells solar design software.

Kenya’s installed solar capacity was 514.1 MW in June 2025, according to the EPRA Energy and Petroleum Statistics Report. Captive plants, which commercial and industrial users build for their own use, made up 300.5 MW of that total and grew by 71.3 MW in the year. Every one of those systems started with a drawing.

Kenyan installers face a practical choice: hire a solar drafting service, buy solar PV design software, or combine both. This guide explains what drafting services deliver, which rules shape the drawings, what drives the cost and how to choose, using EPRA and Legal Notice 104 as primary sources.

In this guide, you will learn:

• What solar drafting services in Kenya actually deliver
• Which rules (Energy Act 2019, EPRA licensing, the Net-Metering Regulations 2024, KEBS standards) shape the drawings
• What typical deliverables look like at each project size
• What drives drafting cost, since fees are not published
• When manual drafting beats software, and when software wins
• How to choose a provider without overpaying for scope you do not need

What Are Solar Drafting Services in Kenya?

Solar drafting services in Kenya are technical providers that produce the drawings and documents needed to permit, finance and connect a solar PV system to the Kenya Power grid, or to run it as a captive plant. Many are staffed or supervised by registered engineers.

These services sit between the sales conversation and the installation. A homeowner or business agrees to a project, and the installer or EPC then needs a plan set that shows the system is safe, compliant and sound. That plan set is what drafting services produce.

Who Provides Solar Drafting in Kenya

Installers typically get drafting from four sources:

1. Independent engineering consultancies. Small firms that serve several installers on a per-project basis.
2. EPC in-house design teams. Larger EPCs employ full-time drafters for rooftops and captive plants.
3. Freelance drafters. Individual engineers or CAD operators. Quality control is the buyer’s responsibility, so verify credentials.
4. Software-assisted design. Installers use design software for layout, shading and electrical drafts, then add engineer review where the project requires it.

What Makes Kenyan Solar Drafting Different

Three factors separate Kenyan drafting from generic CAD work.

Licensing runs across the chain. EPRA licenses solar PV workers in classes T1 to T3 and contractors, vendors, manufacturers and importers in separate classes. See the EPRA renewable energy pages for the licensing route and registers.

Kenya Power interconnection gates grid export. The Energy (Net-Metering) Regulations, 2024 (Legal Notice 104) set capacity limits, a feasibility-study requirement above 10 kW and a 60-day decision window.

Credit rules change the design brief. Exported units earn a credit of fifty percent, and unused credits are forfeited at the end of the licensee’s financial year, per regulation 10. That favors self-consumption, so drafters who size systems for maximum export are using outdated logic.

Why Solar Drafting Matters in Kenya’s 2026 Market

Kenya’s solar market has shifted toward captive systems that serve commercial and industrial loads. Faster project execution starts with faster, cleaner design.

The Bottleneck Is Often Paperwork

Installing a rooftop is quick compared with approvals. The licensee must decide on a net-metering application within sixty days of application, and a rejected or incomplete submission restarts the clock. County permits and environmental assessments for larger projects add time. Every delay in drafting delays everything downstream.

The C&I Segment Is Driving Demand

EPRA reports that captive solar PV added 71.3 MW in the year to June 2025 and is the largest source of captive capacity. These projects are more complex than residential ones. They often involve:

• Multiple roof planes with different tilts and orientations
• Structural checks for warehouse and factory roofs
• Battery storage to extend self-consumption past daylight hours
• Diesel-hybrid integration on sites with unreliable grid supply
• Yield and payback reports for financing or capital approval

Each requirement adds deliverables. A simple layout plan is no longer enough, so C&I installers need drafting partners who can produce full engineering packages, or solar proposal software that combines technical outputs with financial modeling.

Utility-Scale and Open Access Need Specialists

EPRA lists 210.3 MW of utility-scale solar. The Energy (Electricity Market, Bulk Supply and Open Access) Regulations, 2026 were gazetted on 8 May 2026, and TL Advocates summarises them as allowing a generator without a Kenya Power PPA to sell directly to large consumers for a wheeling fee, where the load meets thresholds such as 1 MVA on the distribution system. These projects usually need:

• Civil and geotechnical drawings
• Medium-voltage interconnection design with protection coordination
• Environmental impact assessments where required
• Bankable energy yield simulations
• Licensing documentation for the generation route

No single software platform handles all of this. Developers typically use software for preliminary layout and yield, specialist firms for civil and electrical engineering, and external consultants for grid studies. For large commercial solar projects the same principle applies.

Kenyan Regulations and Standards for Solar Drafting

Kenyan drafting works inside one act, one regulator and a set of standards. Check each against the current text before you issue drawings.

The Energy Act 2019 and EPRA

The Energy Act 2019 is the legal foundation, enforced by the Energy and Petroleum Regulatory Authority (EPRA). EPRA licenses solar PV workers and businesses and publishes the net-metering regulations. For drafting, every deliverable should:

• Reference licensed contractors and a registered engineer where the rules require one
• Specify equipment that meets applicable KEBS requirements
• Follow the capacity and process rules in the Net-Metering Regulations for grid-tied systems

Net-Metering Rules That Shape the Drawing Brief

The table summarises Legal Notice 104 of 2024 as published by EPRA.

A system size above the cap, or a missing feasibility study, can stall an application. Regulation 5(1) says “less than 1 MW” while 6(1)(b) says “not exceed one megawatt”, so get written guidance from Kenya Power for a system at exactly 1 MW.

Kenya Power Interconnection Documents

Kenya Power reviews the single-line diagram with the application. A grid-tied SLD normally shows the point of connection, the bi-directional meter, AC and DC isolation, protection, anti-islanding measures and earthing. Confirm the exact checklist against Kenya Power’s current published requirements, because the utility governs what it accepts.

KEBS and Equipment Standards

The Kenya Bureau of Standards (KEBS) sets standards for solar equipment. Your equipment schedule should list modules and components that meet the applicable standards, and you should confirm which certificates the utility and county ask for. An equipment schedule that lists uncertified hardware creates compliance and warranty risk.

NEMA and County Approvals

Environmental and building approvals may apply, especially to larger or ground-mounted systems and to commercial roofs. A drafter who produces only the electrical SLD leaves a gap in the approval chain, so confirm early which county and environmental submissions your project needs.

Typical Deliverables from Kenyan Solar Drafting Services

Scope varies by project size and complexity. The tiers below are a practical guide, not a published standard.

Tier 1: Basic Residential

Tier 2: Commercial and Industrial

Tier 3: Utility-Scale and Open Access

The SLD Is the Critical Deliverable

The single-line diagram is the document Kenya Power reviews with the application. Experienced drafters know the common reasons for rejection and design the SLD to clear them on the first pass. Ask any provider to show a recent diagram that the utility accepted.

Solar Drafting Cost in Kenya: What Drives the Price

Kenyan drafting fees are not published by a regulator or a trade body, and we did not find a reliable public price list. Be cautious about any table of fixed rates, including ones that circulate in marketing material. Ask for written quotes that state scope, revisions and turnaround.

What Drives the Fee

Software Subscription Comparison

Subscription cost per project is simple arithmetic: annual price divided by projects. At SurgePV’s published individual price of $1,899 per year, 50 projects works out to about $38 per project and 200 projects to about $9.50. That excludes training time and any engineer review the project still needs. Compare the result with written drafting quotes at your own volume.

Manual Drafting vs Solar Design Software in Kenya

The choice is not binary. Many installers use both and decide by project type.

When Manual Drafting Wins

• The project is above 1 MW. Civil work, MV interconnection and protection coordination need specialist engineers.
• Custom structural work is required. An old industrial roof needing reinforcement needs a structural engineer, not software.
• A feasibility study is required. Systems above 10 kW need one prepared by an engineer.
• Volume is low. At a few projects a year, a per-project fee can cost less than a subscription.
• Bankable reports are required. Lenders may ask for specific tools and uncertainty analysis for larger projects.

When Software Wins

• Volume is steady. Time saved compounds across a monthly pipeline.
• Speed is a competitive advantage. A same-day concept lets you answer leads while they are warm.
• You need integrated financial modeling. Captive economics depend on self-consumption and the forfeiture rule, which a model can test quickly.
• You want fewer manual errors. One design model feeding the layout, equipment list and proposal reduces copy mistakes.

The Hybrid Model

A common approach is hybrid: software for design and proposals, a registered engineer for structural and feasibility work, and external consultants for grid studies on large projects.

How to Choose a Solar Drafting Service Provider in Kenya

Selecting a provider is a procurement decision that affects every project timeline. Use this checklist.

Red Flags

• No licence or registration details. Licensing is a legal requirement, not an extra.
• One fixed price for every project. A 3 kW home and a 500 kW commercial roof cannot cost the same to draft properly.
• No utility acceptance examples. Any drafter working on grid-tied systems should have some.
• Outdated net metering knowledge. Drafters who ignore the credit-forfeiture rule do not understand the market.
• No revision allowance. Per-revision charges add up fast.

Questions to Ask Before Signing

1. Can you show a diagram that Kenya Power accepted in the last few months?
2. What is your EPRA licence number and your engineer’s registration?
3. How many revision rounds are included?
4. Do you prepare the Kenya Power application, or do I do that separately?
5. What is the turnaround for my project size, and is there a rush option?
6. How do you design for self-consumption given the credit-forfeiture rule?

Common Mistakes When Outsourcing Solar Drafting in Kenya

Mistake 1: Treating Drafting as a Commodity

The lowest-price drafter is rarely the cheapest option. A draft with a missing protection symbol costs weeks of utility delay.

Mistake 2: Ignoring the Credit-Forfeiture Rule

Exports earn a fifty percent credit and unused credits are forfeited at the financial year end. Drafters who size for maximum export without modeling the daytime load design for forfeited credits, not real savings.

Mistake 3: Separating Drafting From Financial Modeling

A layout without a financial model is half a deliverable. Customers need payback against their own tariff and battery economics before they sign. For how payback math works in practice, see our solar panel ROI breakdown, and for the full rules read our Kenya solar regulations guide.

Mistake 4: Not Verifying Credentials

Working with an unlicensed drafter exposes the installer to enforcement risk and can complicate approvals. Confirm licences before any project starts.

Mistake 5: Skipping Structural Checks on Commercial Roofs

Rooftop installations on commercial buildings need structural verification. A package with electrical drawings only leaves you exposed if the roof cannot carry the load.

When to Use SurgePV for Kenyan Solar Drafting

SurgePV is solar design and proposal software. Its published scope covers 3D roof modeling, array layout, shading analysis, energy-yield and financial modeling, electrical workflow support, bill-of-materials output and proposal generation. Use solar design software for the standard rooftops that fill most pipelines, and keep a registered engineer for structural, feasibility and medium-voltage work. SurgePV outputs support design and documentation workflows but do not replace approval by the responsible engineer, authority, lender or utility.

Pair design with solar proposal software to turn the same model into customer-ready output. The shadow analysis tools check production for sites with nearby buildings or trees, and the generation and financial tool builds the payback case. Ask in a demo whether a Kenya Power-format single-line diagram can be produced for your project type, because that is not a published feature.

Conclusion

Solar drafting in Kenya is moving toward a hybrid model that combines software with specialist engineering. The winning installers submit complete, correct applications inside the 60-day window and design for self-consumption.

Three actions to take this week:

1. Audit your current drafting cost per project. Include revision rounds, utility resubmissions and delay.
2. Verify your drafter’s credentials. Confirm EPRA licensing, engineer registration and a recent accepted diagram.
3. Test a hybrid workflow. Run your next residential projects through design software and your next commercial project through a manual drafter, then compare cycle time and cost. To start, book a SurgePV demo.

Frequently Asked Questions

What are solar drafting services in Kenya?

Solar drafting services in Kenya are technical providers that create single-line diagrams, layout plans and interconnection documents for solar PV systems. They work within the Energy Act 2019, EPRA licensing and the Net-Metering Regulations 2024, and larger projects need an engineer’s input.

How much do solar drafting services cost in Kenya?

Fees are not published, and rates vary by system size, engineering scope, revision rounds and turnaround. Ask for written quotes that state scope and included revisions, then compare the total including any resubmission cost.

Do I need an EPRA licence to do solar drafting in Kenya?

EPRA licenses solar PV workers in classes T1 to T3 and contractors, vendors, manufacturers and importers in separate classes. Check EPRA’s registers for the licence that fits the work you do, and use an engineer for feasibility studies above 10 kW.

Can solar design software replace manual drafting in Kenya?

For standard rooftop layouts it can cover much of the drafting workflow, but it does not replace engineer approval. Systems above 10 kW need an engineer’s feasibility study, and utility-scale, structural and medium-voltage work need specialists.

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

Expect a site layout plan, a single-line diagram with protection, a stringing configuration, an equipment schedule and the net metering application pack. Larger projects add a feasibility study, structural verification, a yield report and county or environmental documents where required.

What does Kenya Power need for a solar net metering application?

The consumer applies to the licensee on Form 001, and systems above 10 kW need a feasibility study prepared by an engineer. Domestic systems are capped at 4 kW single-phase or 10 kW three-phase, and the licensee decides within sixty days of application.

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

Drafting services produce technical drawings for a per-project fee, while design software automates layout, shading, electrical workflow support and financial modeling through a subscription. Software gives faster iterations and one linked model, and a registered engineer still handles approvals.
