How Tower works
Clear first. Verified before you commit.
Your first estimate is designed to help you understand the possibilities. A real proposal requires your permission and verification of the property, utility usage, equipment, and financing.

Tower Solar LLC is a Pennsylvania solar information and project-support company. We help homeowners understand preliminary system sizing, production, pricing, and purchase options before choosing whether to request a verified proposal. Calculator results are educational and do not replace a site survey, engineering review, installer proposal, or utility analysis.
Where we work
Our primary service area includes Philadelphia, Bucks County, Montgomery County, and nearby South Jersey. Preliminary online estimates may be available for other U.S. properties.
How we work
We begin with transparent assumptions and do not send your information to Tower Solar unless you choose to contact us. Equipment, contractors, incentives, financing, and final pricing require separate verification.
