Best Free Solar Design Software of 2024

Pre-feasibility is all about accurate estimations of solar energy potential. It is important that the pre-feasibility study be done efficiently, in addition to providing accurate results. The iMaps, and pvPlanner, are both Solargis prospecting tools that provide quick access to reliable estimates of solar yield. The new Prospect tool increases the accuracy of estimates, and makes it easier for people to work together efficiently on the development solar projects. Solargis data is the most reliable and accurate among all solar databases. Numerous independent studies have confirmed this. Solargis data has been verified at more than 1000 locations around the world. Our validation map shows validation statistics for 180+ sites that are not confidential. Popular simulation software like PVsyst offers advanced capabilities for system design, energy modeling, and more. However, these tools do not have the best default weather data.

The RETScreen®, Clean Energy Management Software Platform enables low-carbon planning and implementation, monitoring, and reporting. RETScreen Expert is a premium version of the software that is completely free-of charge in Viewer mode.

Web Solar Cloud is an easy-to-use online tool for designing solar project. It helps you create professional solar designs quickly, even if you're new to solar design. The software will create a package of documentation for your local permit requirements, including detailed solar panel layouts and electrical diagrams.

PVSketch is a web-based app that simplifies the process of developing solar projects. Sales professionals have easy access to a precise layout tool via a friendly interface. PVSketch allows you to visualize solar energy solutions and generates accurate energy modeling. PVSketch is part the PVComplete platform. PVComplete allows solar installers, developers, and engineers to collaborate on a single platform that combines efficiency and accuracy. Sales professionals can quickly start a project online with PVSketch. Then, they can transfer it to PVCAD, our AutoCAD plugin for a detailed engineering plan. PVSketch makes solar design simple. In just five clicks, you can create a solar project that is rich in valuable information. A simple and intuitive drawing tool makes accurate solar design easy for anyone. A single click can create a complete layout, but if you dig deeper, you can refine your solar design to create complex designs.

Web-based PV design for commercial and utility-scale solar. Our innovative, patent-pending system for determining layout optimizes Ground Coverage Ratio. It also helps engineer higher yields on rugged terrain. You can handle complex boundaries and obstructions easily. SunDAT automates workflows and increases efficiency in your design process. This feature allows you flag areas in a solar array layout that require grade or avoidance, or areas that exceed a certain slope tolerance. You can also view heatmaps and export them to PVsyst. Additionally, you can calculate pile length. SunDAT allows you to export project data in multiple formats, such as PDF, DXF, and DAE. This allows you to import your design into AutoCAD or PVsyst to continue design and analysis. SunDAT Web software optimizes large scale utility and commercial PV design. SunDAT Web software can help you design a 150MW utility-scale rooftop solar system or a 2MW commercial rooftop solar system.

You can quickly and easily create permit-ready residential designs for solar power. In just minutes, you can export ready-to-submit permit package for as low $49 as Just click a button to generate a ready-to submit solar permit package. Each interaction is quick and easy. Lyra is so simple to use that even experienced solar professionals can jump in. Design just what you need for a permit, from a simple preliminary design to a down-to-the-component level permit-ready design. With a click, you can generate a permit package using the design. It's really that simple. Lyra's solar design tool can be used for free. We only need your email address to set you up and get you started on your first design. We work with solar design software firms to enhance their offerings. Contact us if you do not have permit packaging for your product offerings.

SolarEdge Designer is a web-based tool that allows solar professionals to reduce PV design costs and create winning customer proposals. This powerful selling tool can help you close more sales by helping you plan, build, and validate your SolarEdge residential or commercial systems. The design process is simplified with many automated procedures, including stringing, design validation instantly, and bulk Power Optimizer barcode map mapping. Easy export of site layouts to the SolarEdge Monitoring Platform. Provide compelling customer proposals that include detailed reports and energy simulations. These simulations have been independently evaluated by DNV GL. To accurately forecast system owners' electricity bills savings and ROI, you can use financial analysis capabilities. A 3D simulation of your customer's site will impress.
