It is the software solar companies use to design systems, estimate power, send quotes, track leads and run jobs. Most companies use more than one tool.
We sort it into 9 types: Design & simulation, CRM & lead management, Monitoring & asset management, Proposals & sales, Operations & project management, Site selection & GIS, Storage & microgrid, Aerial & thermal inspection, Dealer & sales teams.
Start with the job you need done. Open that category, read two or three reviews, then compare the two closest. Check how each one charges, if it has a free plan or trial, and what it connects to.
Design software plans the panels, checks shade and estimates power. A CRM tracks leads, calls and deals. Some tools do both. Each review shows which jobs a tool covers.
