How to compare solar companies

When people say "solar company" they might mean any of these:

• Manufacturers make the panels, inverters or batteries. They don't install.
• Installers design and physically install systems. This is who does the work on your roof.
• Dealers / sales orgs sell under a brand and subcontract the install.
• Financiers provide the loan, lease or PPA and often the monitoring and warranty.

Many large "solar companies" are a mix — a brand and financing layer on top of a network of local crews.

Comparison checklist

• Who actually installs — in-house crews or subcontractors?
• Price per watt after all fees, cash vs financed.
• Equipment brands and warranty terms.
• Licensing and insurance in your state.
• Who you call for service in year 5.
