Create polished, personalised proposals in minutes, not hours. Present customers with a professional (online or PDF) offer that clearly illustrates the system in 3D as well as savings, costs and benefits. This builds trust and helps them make confident decisions. Manage costs, components and customer interactions in one system, from initial inquiry to signed offer, without switching tools or re-entering data. Fewer errors, more professional proposals, and a faster sales process that helps you close deals while customer interest is at its peak.

Build accurate project designs in minutes with our powerful 3D site modeler. Use the best data available for every project, including satellite imagery, orthophotos, LiDAR building data in Germany and Switzerland, or even drone-based 3D models.

Assess shading, optimize layouts and dimension inverters, batteries and strings with confidence before stepping on site.

Use the same project model throughout the entire customer journey, from visually compelling sales proposals to detailed engineering deliverables. As projects move forward, refine the design and automatically generate roof plans, string plans and single line diagrams without duplicate work. Reduce site visits, avoid planning errors and deliver projects faster with a single source of truth.

Keep every project moving from sale to installation. Assign tasks, track progress and manage project milestones in one shared workspace. Create phase-specific task lists for planning, permitting, procurement, installation and handover, ensuring everyone knows what needs to happen next.

Collaborate seamlessly across sales, engineering, project management and installation teams. Follow up on open items, prevent bottlenecks and keep projects on schedule with clear ownership and visibility.

The result: fewer delays, less rework and always knowing exactly where every project stands.

Spend less time on paperwork and more time on profitable projects. Automatically generate permitting documents, installation documentation, commissioning papers and handover reports from the data already stored in your system.

Keep versioned documents, approvals and project information in one central location while eliminating duplicate data entry across teams. Automating repetitive administrative work helps your team deliver more projects with the same resources while reducing mistakes and delays.

Know exactly how your business is performing. Track project status, sales activity and implementation performance in real time. See where every project stands, how many deals have been won recently and which bottlenecks could impact delivery or revenue.

Build the project views you need to turn data into action. With complete visibility across your business, you can identify problems early, stay ahead of trends and make informed decisions with confidence.

The result: greater control, fewer surprises and a more profitable business.

Embed on your website or use as a stand-alone tool to capture quality leads and deliver personalised PDFs. Give potential customers instant insights into their renewable energy options and costs. Our fully customisable online calculators work 24/7 as a first touchpoint for Solar, Heating or EV Charging projects.

Shadow Analysis

Use real shading data to optimise panel placement. See shading from roofs, buildings, and terrain. Heatmaps show shading on all roofs. Get panel-level shading factors for better planning.

Drone photogrammetry

Use drone-to-3D PV planning. Turn drone imagery into a high-precision 3D model and orthophoto for accurate PV planning that is based on real measurements, not guesswork.
New Integration!
New integration with Airclip

String Design

Design electrically compliant strings, auto-generated or manual. Adjust strings with click & drag and quickly assign strings to MPPTs and batteries. Instant compliance checks to prevent errors early.

Single-line Diagrams

Automatically generate a clear, standardised electrical schematic of the entire PV system. From modules to inverters and grid connection for streamlined documentation and compliance.

Eturnity’s software for calculations and quote creation provides us with strong support. We particularly appreciate the extensive component library, as well as the ability to add our own custom components. What really stands out is that the software is continuously developed and regularly enhanced with new features. Capabilities such as 3D roof and layout planning, multiple quotation statuses, and the ability to track tasks and quotes over time are just some of the many possibilities Eturnity offers.
