Solar installation moves fast. You handle site surveys, system design, proposals, permits, installation, and inspections. The right apps help you stay organized and close jobs without adding extra admin work.
This guide covers the best solar apps for installers in 2026. We break them down by design tools, shading analysis, proposals, CRM systems, and documentation platforms so you can choose what fits your workflow.
Solar Design Software
Design software helps you create system layouts, calculate production, and prepare accurate proposals. These tools are often used during the sales and planning stage.
Aurora Solar
Aurora Solar is built for detailed system design and performance modeling. It allows you to create roof layouts, run shade analysis, and generate production estimates. Many larger solar companies use it for engineering-level accuracy and proposal support.
Aurora works well if you want advanced modeling and strong visuals for client presentations. It may be more than you need if you run a small crew and prefer simpler tools.
HelioScope
HelioScope focuses on accurate system simulation and layout. It allows you to model stringing, panel placement, and expected energy production. Installers often use it when they need reliable production reports.
This platform is strong for technical planning and engineering review. It supports teams that want detailed documentation before installation begins.
OpenSolar
OpenSolar combines system design with proposal creation. It allows you to build layouts, calculate production, and generate quotes in one place. Many small and mid-sized installers choose it for its accessible pricing.
If you want design and sales tools inside a single platform, OpenSolar can simplify your process. It works well for teams that want to move quickly from site survey to signed contract.
Shading Analysis Apps
Shade plays a major role in system performance. Digital shading tools help you measure solar access and document roof conditions during site surveys.
Solmetric SunEye
Solmetric SunEye is designed specifically for shade analysis. It captures sun path data and helps you determine how shading affects production. Many installers use it during on-site assessments.
This tool is ideal if you need accurate shade measurements for system sizing. It supports more technical planning and performance validation.
PVWatts
PVWatts is a production calculator developed by the National Renewable Energy Laboratory. It allows you to estimate system output based on location, tilt, and system size.
Installers often use it as a quick validation tool. While it does not replace full design software, it helps confirm production assumptions early in the process.
Documentation and Job Site Apps
Clear documentation protects your business. Photos, notes, and inspection records should be organized by project and easy to access.
CompanyCam
CompanyCam allows you to organize job site photos by project and share them across your team. You can capture before-and-after documentation, installation progress, and inspection details.
For solar installers, this is especially useful for roof condition documentation and final install verification. Keeping visual records organized supports smoother inspections and customer communication.
DJI
Drones from DJI help you capture roof photos safely and efficiently. Aerial documentation supports site surveys and marketing materials.
Instead of relying on ground-level photos, you can document roof layout and surrounding obstructions clearly. This strengthens both design accuracy and client presentations.
How to Choose the Right Software
Start by identifying your biggest bottleneck. If design takes too long, focus on layout and modeling tools. If closing deals is the challenge, invest in stronger proposal software.
As your company grows, CRM and documentation tools become more important. Organized data helps you scale without losing visibility. Choose apps that integrate into your daily workflow.
The best solar apps in 2026 are the ones that reduce manual work and improve clarity. When design, sales, and documentation are connected, your projects move forward with fewer delays and fewer surprises.
Stay organized from survey to install.
