Voltflo vs. The Alternatives
A straight comparison - no fluff.
Voltflo vs. HubSpot
The Problem with HubSpot
HubSpot is a powerful marketing platform - but it was built for e-commerce and SaaS, not solar. There's no concept of a solar proposal, no lead qualification flow for roof type and bill size, and no way to track which Google Ads campaign generated an actual installation. You end up stitching together third-party apps that cost more than the CRM itself.
The Voltflo Advantage
Voltflo captures and self-qualifies solar leads on your website, generates instant proposals with your own pricing, and tracks every lead back to its source - all out of the box. And if you want to keep HubSpot for your broader marketing, Voltflo integrates directly with it.
Voltflo vs. GoHighLevel
The Problem with GoHighLevel
GoHighLevel is a great automation tool for agencies. But solar isn't a generic service business - and GoHighLevel knows nothing about solar. You'll spend weeks building custom pipelines, writing qualification flows from scratch, and integrating proposal tools that still don't talk to each other properly. It's cheap to start but expensive in time.
The Voltflo Advantage
Voltflo is ready for solar from day one. The lead capture flows, pipeline stages, proposal generator and marketing attribution are all built in - configured for how solar installation businesses actually work. No setup marathon required.
Voltflo vs. Zoho
The Problem with Zoho
Zoho offers a wide suite of tools, and it's genuinely flexible. But that flexibility is the problem - you need a developer or months of configuration to make it work for solar. Most installers who try Zoho end up with a half-configured system that their team doesn't fully use.
The Voltflo Advantage
Voltflo is purpose-built. Your team doesn't need training on a generic CRM and then a separate workaround for solar. Everything they need - from first enquiry to signed proposal - is in one place, built the way a solar sales process actually works.
Voltflo vs. Monday.com
The Problem with Monday.com
Monday is a project management tool that's been stretched into a CRM. It's great for tracking tasks, but it has no lead capture, no proposal generation, and no marketing attribution. Solar installers end up using it alongside spreadsheets, separate proposal tools, and manual follow-up - defeating the purpose.
The Voltflo Advantage
Voltflo replaces the patchwork. Lead capture, pipeline management, proposals, booking and attribution in one platform. If you want to keep Monday for project delivery, Voltflo integrates with it - so your sales and operations stay connected.
Voltflo vs. OpenSolar
The Problem with OpenSolar
OpenSolar is a strong free solar design and proposal tool - but it doesn't capture and qualify leads on your website, manage a sales pipeline, or track which marketing channels drive real revenue. Many installers outgrow it as their business scales.
The Voltflo Advantage
Voltflo is the conversion and pipeline engine - many installers run both. Voltflo captures and qualifies the visitor before a design is ever needed, then manages the pipeline through to a signed job.

The Problem with Easy PV
Easy PV designs the system and builds the kit list - but it doesn't capture website visitors, qualify leads, generate commercial proposals, or manage a sales pipeline. It's a design tool, not a sales engine.
The Voltflo Advantage
Voltflo wins the customer. Different jobs - Voltflo owns the sales journey from first click to signed job. Many installers use Easy PV for design and Voltflo for the sales process.
