Solar software, particularly solar design software, is a key asset in creating outstanding solar system designs, project proposals, and ensuring a solar company meets compliance requirements and relevant regulations.
From design planning to optimization and analysis of models you’ve built, to creating sales proposals and ROI analysis, and even down to installation and monitoring, solar software tools are built to make each phase of the solar project and sale have faster turnaround times, saving you time, resources, and even nerve cells.
Just as your team’s sales rep, engineer, installer, and maintenance tech all play different roles, solar software tools are not all the same – they have different functions and features. To ensure your system operates smoothly, carefully consider the software selection for your solar project management needs.
If you’ve ever tried using one solar PV software for everything, you’ve probably seen the cracks — and maybe that’s why you’re out looking for another, more suitable PV software solution.
Most solar business software platforms focus on design aspects like 3D modeling and visualization using LiDAR data or drone surveys, while others prioritize workflow automation, simplifying repetitive stages from site surveys to permitting, installation, and down to the final inspection.
Although true, there are more highly industrialized solutions that offer end-to-end assistance. Still, in case you only need a solution that focuses on a single aspect of your operation, then you don’t need to subscribe to a full-fledged solution. If you’re a sales-focused solar company, then you may not need a full engineering suite, and vice versa.

The key to selecting the best solar power software is to match it to your current needs. Don’t focus too much on just what sounds impressive on paper.
With your team, think about: “Where do we spend most of our time in the solar project cycle?” Then, pick the tool built for that phase.
Here are our personal cherry-picked tool recommendations:
Whenever possible, we highly recommend trying demos or free trials first before committing. That way, you can test the waters and see which best suits your team’s adoption rate, clients’ needs, and most of all, your budget.
With the rise of AI and automation, we can expect its impact on the next generation of solar software solutions. For instance, consider a solar power plant design software that uses drone footage for instant solar system design. Or a solar management software platform that predicts panel degradation even before it happens.
There is just so much we can think of! And with further innovation, possibilities are endless…
Perhaps by 2030, that’s half a decade from now, these solar software companies can evolve to offer fully integrated suites covering AI-powered solar estimating software, solar proposal tools, and solar panel monitoring software — all in real-time.
We hope this comprehensive solar software tool guide 2025 helps you pick the best choice. Choose not the most flashy one on paper, but one that makes your next solar projects work 100x faster, easier, and far more accurate.
