DUET is a next generation energy yield modelling solution for new and existing utility-scale solar assets. From site design through to operations, the 3D physics-based model delivers clarity where standard 2D models rely on guesswork. DUET protects asset value and reduces underperformance risk across solar portfolios with advanced capabilities such as sub-hourly yield simulations, near-shading, custom racking inputs, terrain-inclusive simulations, and cell-level irradiance modelling. These capabilities enable users to narrow the P50/P90 spread, unlock higher energy yields, and deliver breakthrough returns. Proven daily on 130+ operating solar assets, DUET enables operations teams to compare actual asset performance to validated benchmarks to identify and quantify system losses. Pinpointing underperformance events faster and more effectively is the key to maximizing availability and achieving production targets. During construction and commissioning of an asset, teams can use DUET to accelerate capacity and performance tests with custom workflows specifically designed to streamline the process. DUET’s extensive features help teams comply with new testing standards for PV systems like IEC 61724-2. On the design side, the physically representative model built with DUET allows teams to replace empirical loss assumptions with leading edge, physics-based irradiance modelling to achieve 99+% accuracy against field-measured data. An accurate and capable model that supports every phase of a solar asset’s lifecycle is vital to eliminating team silos and ensuring contracted targets are exceeded and profitability is protected. DUET achieves this by combining a decade of research with leading edge technology that offers unmatched precision and user experience.
Ecosuite is distributed energy resource management software designed to deploy and operate DERs at scale using open-source foundations and AI technology. The platform offers asset management tools powered by edge-compute technology for grid operations, enabling monitoring, maintenance, and control of assets via mobile and web interfaces. Ecosuite includes Foresight, an AI-enabled feature for predictive maintenance, energy forecasting, and project underwriting. The software integrates a Department of Energy-funded data science toolkit for managing diverse energy resources. Modules streamline project milestones, cashflow forecasting, partner engagement, and underwriting processes. Finance and underwriting tools support investment decisions, while grid services function as an energy network operating system. Built on open-source infrastructure and validated by the Department of Energy, Ecosuite addresses portfolio performance and operational efficiency through collaborative methodologies.

Enact’s platform enables sales teams to design, price and sell remotely, finalize contracts and track project execution. End-customers can also leverage Enact’s platform to manage their solar and energy storage transition and track financial outcomes
At Eturnity we admire the power of renewable energies and are convinced that it will be possible to supply the world with energy from renewable sources only. By simplifying sales, consultation and quotation processes for decentralized energy systems we help making the energy transition more efficient and affordable for everyone. Eturnity designs, fosters and develops a cloud-web platform which revolutionizes the way solar and heating installers, consulting companies and energy utilities sell decentralized energy systems. The Eturnity software integrates the complete sales and consultation process from the first end-customer contact to the final quotation into one single platform. The process is seamlessly integrated and thereby simplifies the acquisition process and improves information efficiency. On-site consultation, layout and dimensioning, simulation, profitability calculation and the generation of quotations can easily be manged on one platform. By providing attractive quotations and comprehensible information to end-customers the platform furthermore fosters customer-centricity and thus enhances success and efficiency of consultation processes.
Free Energy PRO is a unified B2B SaaS and CRM platform for solar installers and energy efficiency contractors. It features a high-precision satellite CAD PV Planner to draw multi-pitch roofs, calculate module tilt and obstacle exclusion, estimate PVGIS annual energy production, and export multi-page branded PDF quotes for commercial and residential roofs.
GeoT*SOL is the professional software for planning and designing heat pump systems, both for existing and new buildings. The program offers a choice of different heat sources (air, water, geothermal), operating modes and numerous system configurations for every location. Photovoltaic and solar thermal systems can also be seamlessly integrated into the design. Based on a dynamic minute simulation, electricity consumption, seasonal performance factors, operating costs and other system data can be calculated, taking into account blocking periods and tariffs. Finally, key results are compiled in a freely customizable project report for the customer.
Gridcog is energy modelling software for solar, battery energy storage system (BESS), hybrid, behind-the-meter and e-mobility projects. It simulates the physical and commercial performance of each project, interval by interval, across multiple sites and markets. Developers, independent power producers (IPPs), investors, consultancies and large energy users use Gridcog to size solar and battery projects, model revenue from wholesale markets, ancillary services and power purchase agreements (PPAs), assess merchant exposure and negative pricing, and test dynamic grid connections. Results include IRR, NPV and cashflows across scenarios, ready for investment approval. Gridcog shows developers and investors the full range of a project’s returns, with every assumption visible, before they commit capital. Gridcog has modelled more than 18,000 energy projects across 40+ markets, has teams in London, Berlin, Madrid, Perth and Melbourne, and is backed by ABB, DNV, Axpo and VERBUND.
HelioTest is a capacity testing software for solar PV projects. It replaces the spreadsheets and ad-hoc scripts most engineering teams still use to run ASTM E2848 capacity tests and contractual availability tests, with a guided workflow that takes you from raw measured data to a stakeholder-ready PDF report in one session. Set up your site once (PV parameters, array orientations, sensor layout), upload measured data as CSV or pull it directly from SolarEdge and AlsoEnergy, and HelioTest applies the ASTM E2848 filtering and regression automatically. Every test run records the inputs, filters and site geometry used, so results are reproducible and defensible in front of lenders, offtakers and independent engineers. Built for real-world sites: supports bifacial modules, multiple array orientations, and sites where only GHI irradiance sensors are available. Availability tests run alongside capacity tests in the same workflow. HelioTest is used by EPCs, asset owners, owner's engineers and independent consultants who need repeatable, documented performance tests without the cost of a one-off consulting engagement. Start free, buy a single test one-time, or subscribe for ongoing testing across a portfolio. A managed service option is available for teams who prefer to have tests run for them.
Built on UL Solution's trusted HOMER hybrid power optimization platform, HOMER® Front models the technical and economic performance and dispatch of utility-scale energy storage systems – either independently or along with solar and wind.
