Planning & Design

Alo alo merci

Model the roof, place the panels, and show the customer exactly what their home will look like, from a quick 2D sketch to a fully detailed 3D layout, with obstacles, angles and shading accounted for.

WHY IT MATTERS

Every roof and every customer has different requirements.

Installers must define accurate roof data and design PV systems that reflect both real-world constraints and the end-customer’s expectations. The challenge is balancing speed and accuracy while making sure the final design matches what the customer actually wants: maximum output, visual appeal, or cost-efficiency.

THE TOOLS

One flexible toolkit for every stage of the design.

Customer-centric design support
PANEL FIELD TOOL Automatically fill roof areas with panels, or place them manually to match what the customer actually wants, the maximum output or the best-looking layout.
Roof modelling, made precise
ROOF TOOL Draw roof shapes with snapping aids that keep everything symmetrical and accurate.
Extrude with cascading updates
HEIGHT TOOL Adjust roof height and let the change cascade automatically across every connected roof section.
Placement guidance built in
OBSTACLE TOOL Define chimneys, skylights and other physical or planned obstacles that affect where panels can go.
Buffer zones, automatically enforced
MARGIN TOOL Set safety margins around roofs and obstacles to prevent invalid or unsafe panel placements.
Built for large, complex projects
SELECTIVE UPDATING Only the edited panel field re-renders, keeping even high-kWp commercial designs fast and responsive.
Customer benefits

Design freedom that still keeps you fast.

Design freedom, any project size

From a quick sketch to a fully detailed plan — equally suited to residential and commercial projects.

Efficient, guided workflows

Snapping, margins and auto-fill reduce manual work while helping you avoid design errors.

Real-world accuracy, digitally delivered

Model actual roof conditions, obstacles and constraints for a design that reflects reality.

Customer-centric flexibility

Tailor every design to what the customer values most — output, aesthetics, or budget.

Fast, visual communication

Show the finished system in 3D so the customer can understand and approve the design on the spot.

Smooth even at scale

Enjoy responsive interaction regardless of panel count or system size — including high-kWp commercial designs.
How it works

From roof to customer-ready 3D view.

Define the PV system

Create a quick visual proposal for a residential sale, or model a complex commercial roof in detail for engineering and permitting.

Refine the design

Adjust based on customer feedback, technical constraints, or site-specific details — shading, roof geometry, available space.

Showcase to the customer

Present a realistic 3D view that helps the customer visualise the system as if it were already installed.
Three steps from project to compliant PDF.

1. Your project data is already there

Modules, inverters, strings and components are already defined in Eturnity from planning, nothing to re-enter.

2. Eturnity draws the diagram

The Single Line Diagram is generated automatically, matching your most current project data, on a true drawing canvas, not a rigid template.

3. Fine-tune and export

Adjust freely where needed, then export a titled, submission-ready PDF for permitting, grid connection or the system manual.
Competitive advantage

Automated. Yet still flexible.

Most tools force a trade-off between speed and control. Eturnity’s Single Line Diagram is built on a true graphical canvas, so automation never comes at the cost of flexibility.
