Independent DC Engineering for Utility-Scale Solar PV

Layouts, yield models and tender-ready FEED packages for developers, IPPs and EPC contractors building utility-scale ground-mount PV across Europe — including hybrid and grid-constrained sites. Designed with construction in mind, so projects move between stages without redesign.

Klaudas Žylė — Founder & Lead PV Design Engineer

Klaudas Žylė has worked across the full solar design chain since 2018: design engineer, in-house engineer at a full-cycle EPC, two years on the construction side of utility-scale plants, lead project engineer and PV design team manager. He founded CloudlessPV in 2025.

That path shapes how every project is designed: clarity, practicality and buildability over unnecessary complexity. Recent work includes an 18 MWp plant in Georgia (full DC FEED package), a 91 MW tracker project and a hybrid solar plant in Lithuania, and a landfill PV site in Sweden. Clients work directly with the engineer, not through an account manager.

PV Design Services

From an independent audit of an existing layout to a tender-ready FEED package.

Utility-scale PV layout drawing under review

Design Audit

Already have a layout? An independent re-derivation of your design, with capacity, yield and buildability findings in engineering units.

Conceptual Design

No design yet? 3D site layout, PVsyst yield model, preliminary SLD and bill of quantities — the basis for a go/no-go decision.

Comparison Study

Module, inverter and transformer options compared side by side on yield, quantities and performance before anything is locked in.

Planning Phase

The drawing set a planning authority asks for: layout with setbacks and heights, frame and MV station details, earthing, SLD and PVsyst.

FEED

Tender-ready DC and LV AC design: stringing, cabling, trenching, earthing, SLD, cable schedule and bill of quantities — what EPCs price from.

Why CloudlessPV

Nearly a decade in solar PV design, 1 GW+ designed across 15 countries.

CloudlessPV is a specialist solar engineering practice focused on moving utility-scale PV projects across Europe from land to construction with minimal technical friction. It designs DC systems for ground-mounted power plants from 1 MW to 500 MW+, helping projects pass permitting, technical due diligence and tender without costly redesign cycles.

The work is built around one principle: design it right before it becomes expensive to fix. Layouts are engineered with construction and procurement in mind, which cuts delays, change orders and scope uncertainty between project stages.

Clients work with CloudlessPV when speed, credibility and buildability matter.

Direct engineer access

The engineer who designs the plant is the one answering your emails. No account manager in between.

Fixed fees

Priced by project size and deliverables before work starts, with an instant quote online.

Built for construction

Two years on the construction side shape every layout: access, trenching and tolerances from the first draft.

Independent

An independent design practice: recommendations follow the numbers, not an equipment or EPC contract.

Software

Deliverables are produced in AutoCAD, PVcase, PVsyst and QGIS — the software developers, EPC contractors and technical advisers already work with, so files move between teams without conversion.

Frequently Asked Questions

Who does the design work?

Every project is designed by the founder and lead engineer. Clients deal with the engineer directly, not with an account manager.

Where should a project start?

No design yet: Conceptual Design — a PV layout on its own is the lowest-cost start. An existing design and a doubt about it: Design Audit.

Which project sizes and locations?

Ground-mount PV from 1 MW to 500 MW+, including hybrid PV and BESS sites. The focus is Europe: projects in 15 countries so far, delivered remotely.

How is the price set?

A fixed fee by project size (MWp) and the deliverables selected. The quote form gives an estimate in minutes; the price is confirmed in writing before work starts.

Can an NDA be signed before files are shared?

Yes. Ask for one before sending anything.

Is AC or grid connection design included?

DC and LV AC design are in scope. MV AC and grid connection studies stay with your team or are quoted separately through a partner network.
