OpenSolar is free to start.
Powerlily is paid for by installers.
OpenSolar gives installers a free design, proposal and project platform funded by hardware, finance and service partners. Powerlily is a subscription your company pays for, so the platform answers to you, and it keeps going after the sale into the client portal, crew scheduling and multi-brand fleet monitoring.
Credit where it is due
What OpenSolar does well.
OpenSolar is a capable platform, and free is a real advantage. Its own pages list:
- A free core platform
- Design, proposals, CRM and project management at no subscription cost, funded by partners who pay to be on the platform.
- Built-in invoicing and payments
- Branded invoices, payment milestones and automated payment reminders.
- Hardware and finance in the workflow
- Distributor ordering with a calculated bill of materials, integrated finance options and permitting.
One record, from the knock to the service call.
The sale, the install and, on Pro, the monitored system share one customer record, so nothing is re-keyed between tools. The plan is priced for the company, not the seat.
Who pays for the software
OpenSolar is funded by manufacturers, finance companies, distributors and other partners. Powerlily is funded by the installers who use it. Your catalog, prices and finance choices stay your own, and online payments on Pro land in your own account with no Powerlily cut.
Premium imagery on the plan
OpenSolar offers free imagery with premium captures paid per image. Powerlily includes Google HD and Bing imagery from Essentials, EagleView from Standard, and Nearmap and drone survey processing on Pro. There is no imagery wallet to top up before a design.
Beyond the sale
After the signature, the same record runs the install and the years after it: crew scheduling, Site Safety forms, a branded client portal and multi-brand fleet monitoring. Lilypad takes it to the door and the roof.

Who each one is for.
- OpenSolar may fit if
- Keeping software cost at zero is the priority, and partner-funded hardware, finance and imagery options suit the way you buy.
- Powerlily may fit if
- You want software that answers to the installer paying for it, imagery included in the plan instead of a wallet, and the customer carried through installation, monitoring and service on one record.
