SolarTuner

Plan smarter solar projects with SolarTuner. Explore rooftop installations, check balcony solar kits and prepare detailed solar PV plans directly from your phone. SolarTuner brings measurements, visual panel design, production estimates and project documentation together to help you understand your options before installation. PLAN YOUR SOLAR PROJECT Create a plan for a roof, balcony, facade, ground-mounted installation or carport. Enter the available area, system details and electricity consumption to explore different system configurations. For more complex projects, Pro supports multi-surface planning so you can account for surfaces with different orientations and slopes. MEASURE DIRECTION & TILT Use your phone's sensors to measure surface orientation and tilt. Capture measurements for panel planning and production estimates, or use manual direction controls where available. On the map, a rotatable compass overlay helps you adjust the intended panel direction when an automatically detected orientation does not match the surface. DESIGN PANELS ON THE MAP With Pro, draw installation areas and position panels on the map to explore how a system fits your available space. Adjust panel dimensions, orientation and layouts, work with panel arrays, and refine placement across different surfaces. Compare practical layout options before moving on to production and cost estimates. ESTIMATE SOLAR PRODUCTION Estimate annual solar electricity production using your location, system size, orientation, tilt and shading assumptions. Explore how changing peak power or other inputs affects the result. Depending on the selected calculation method and service availability, online estimates can use established solar and climate data services such as PVGIS/JRC, NASA POWER and NREL PVWatts. EXPLORE COSTS & SAVINGS Review estimated production, electricity use, potential annual savings and payback. Adjust the available economic assumptions to explore different scenarios. Pro adds monthly production, long-term savings, battery scenario comparisons and advanced inverter controls to help you evaluate a proposed system in more detail. CHECK BALCONY SOLAR KITS Use the Balcony Solar Kit Check to review key parameters of a planned balcony setup and get a structured overview of the system. This tool is also available to free users, making SolarTuner useful for smaller installations as well as larger PV projects. MANAGE PROJECTS & EXPORT RESULTS With Pro, manage multiple projects using save and import tools, create detailed PDF reports and export CSV data for further review. Bring together measurements, panel layouts, production estimates and financial results in project documentation that you can save or share. UNLOCK SOLARTUNER PRO Start with the free tools and unlock advanced features with a one-time Pro purchase. Pro includes map-based panel design, custom layouts, multi-surface planning, detailed PDF reports, CSV export, extended analysis, battery scenario analysis, advanced inverter controls and additional project tools. No recurring subscription is required for this Pro purchase. LOCAL-FIRST PROJECT STORAGE Projects, measurements and locally generated reports are stored on your device by default. Features such as online maps, solar data requests and information submissions require data to be sent to the relevant services. See the privacy policy for details about data handling and the services used by the app. IMPORTANT SolarTuner is a planning and estimation tool. Actual production and savings depend on site conditions, weather, equipment, tariffs and installation quality. Results do not replace professional technical assessment, structural analysis, electrical planning or advice from a qualified solar or electrical professional.
