Jump to Section
Solar sales are moving from the kitchen table to Zoom. You need a tool that can design a system, calculate savings, and sign a contract in one flow.
Overall Winner: Aurora Solar (Best for Accuracy)
Visit Aurora
1. Aurora Solar: The Titan
Aurora is expensive, but it prevents "Change Orders."
The Problem: You sell a 10kW system. The installer gets on the roof and finds a vent pipe where a panel should be. You have to go back to the customer and lower the system size. The customer cancels.
The Fix: Aurora's 3D modeling is so accurate that the install team rarely has to change the design. It uses LIDAR data for shade analysis, providing "bankable" accuracy that lenders trust.
What we liked
- Industry-leading 3D modeling and LIDAR accuracy
- Significantly reduces post-sale Change Orders
- Trusted by major solar lenders for production guarantees
Room for Improvement
- High monthly subscription cost
- Steeper learning curve for new sales reps
2. Solo: The Proposal Engine
Solo is faster. You request a proposal, and their team builds it for you (human-assisted). It looks great on an iPad. It integrates seamlessly with DocuSign and major lenders like GoodLeap and Sunlight for a one-tap close at the kitchen table.
What we liked
- Extremely polished and beautiful proposal designs
- Human-assisted design team builds proposals for you
- Deep integrations with solar financing partners
Room for Improvement
- Pay-per-proposal model can get expensive at scale
3. OpenSolar: The Free Alternative
OpenSolar is free (supported by hardware partners like Enphase and Qcells). It's a bit clunky compared to Solo, but it's fully functional and a great starting point for smaller installers.
