Trusted by 2,500 renewable energy professionals ⭐⭐⭐⭐⭐

European Partner for the long run.

With 13 years of industry experience, we know technology alone is not enough. While we embrace AI and innovation, we believe great business is still about people. That’s why our experts are there for you personally. From smooth onboarding to fast, reliable support, we’ll be right by your side.

Integrated with your setup.

All-in-one does not exist. For an optimal business process you need multiple providers. That's why we value connectivity. Our software integrates easily with tools you already use, for a smooth workflow across your whole team, preventing double work and minimising errors.

Precision without complexity.

Accurate engineering shouldn’t mean complicated software. Create precise roof layouts, string plans and technical documentation in minutes, not hours. With an intuitive workflow that new users can learn in a day, your team gets productive fast and your business scales with ease.
The Platform

Design Faster. Sell More. Grow Profitably.

Plan, quote, sell, manage and deliver every energy project.

Start your Free Trial

Create polished, personalised proposals in minutes, online or as PDF, with 3D visuals, savings, costs and benefits. Manage costs, components and customer interactions in one system, from inquiry to signed offer, without switching tools or re-entering data. Result: fewer errors, faster sales, more deals closed.

Learn more

Build accurate project designs quickly with our 3D site modeler, using satellite imagery, orthophotos, LiDAR data or drone-based models. Assess shading, optimize layouts and dimension inverters, batteries and strings before stepping on site. The same project model automatically generates roof plans, string plans and single line diagrams, without duplicate work, for fewer site visits and faster projects.

Learn more

Keep every project moving from sale to installation, with tasks, progress and milestones in one shared workspace. Phase-specific task lists for planning, permitting, procurement, installation and handover ensure clear ownership. Sales, engineering, project management and installation teams collaborate seamlessly, preventing bottlenecks. Result: fewer delays, less rework, full visibility.

Learn more

Permitting documents, installation documentation, commissioning papers and handover reports are automatically generated from the data already in your system. Versioned documents, approvals and project information stay in one central location, eliminating duplicate data entry. Result: more projects with the same resources, fewer mistakes and delays.

Track project status, sales activity and implementation performance in real time, including won deals and bottlenecks that could impact delivery or revenue. Custom project views turn data into action. Full visibility helps you spot problems early and make informed decisions. Result: greater control, fewer surprises, 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.

Comes with everything you need to get the job done

System Designer

Create 3D model of the building with module layout, shading simulation and string assignment in a single view. Inverters and batteries are placed and sized directly in the model, including automatic compliance checks for the strings.

Maps, LiDAR and Drone Data

Map data, LiDAR building data (BKG, Swisstopo) and drone imagery processed via photogrammetry, including from partners such as Airclip and Airteam, as a data foundation for every project, usable individually or combined.
Learn more

Extensive Product Library (PIM)

Access to several thousand components from a central product database, including PV modules, inverters, batteries, EV chargers, energy management systems, heat pumps and thermal storage. All data up to date and ready to use for project planning.

Convincing Customer Proposals

Create professional proposals for residential as well as commercial and industrial projects, including feasibility calculations, e-mobility load profiles and a custom electricity tariff model. Proposals can be shared as PDF, online, or with legally binding e-signature.

Integrated Profitability Analysis

Make selling energy systems profitable. See at a glance how profitable a project is for your own business and how much room there is for discounts, before the proposal even goes out.

Technical Planning & Documentation

A complete set of implementation-ready documents is automatically generated from the sales design: roof plan, string plan and single line diagram, including all technical specifications and labels.
Learn more

Integration with Mounting Systems

Transfer project designs directly to common mounting system software, such as K2, Solar.Pro Tool, Novotegra, Clenergy or GSE. No more manual data transfer required.

Price Synchronization & Ordering

Synchronize prices and product catalogs directly with your preferred distributor and place orders with a single click. In Switzerland, including Krannich, Solarmarkt and Solexis, in Germany with Tepto, in the UK with UK Greentech, and in Sweden with Aprilice.

Permitting & Administrative Documents

Every energy project comes with a lot of paperwork. Permitting documents and other administrative documents can be automatically filled in from existing project data, saving time and reducing errors.

Project Management

Configure your own workflows for each project phase and hand off projects smoothly from sales to the project team. Task management, reminders and phase-specific checklists keep quality consistently high across every project.
Any Project Size

Residential properties and Commercial & Industrial installations

Choose from load profiles tailored to different building types and use cases, making it easier to model your project accurately.
