Make solar feel
easy to understand.

Most solar quotes ask you to picture a number on a page. We'd rather show you the system on your roof. Adjust your energy goals below and watch your panels, battery, and EV charger appear in real time, before you ever talk to a sales rep.

  • Set your energy offset goal and watch your panel count adjust instantly.
  • Add battery backup or EV charging to see exactly what you're getting, not just a line item.
  • When you're ready, upload your utility bill and we'll turn this into a real quote.

Estimated pricing and system size are for illustrative purposes only and may vary based on roof orientation, shading, structural factors, local permitting, and current utility rates. Actual quotes may differ. West Coast Solar pricing shown reflects conservative published rates — final proposals are typically lower. This tool is not a contract or commitment.
Simple Process

Three steps.
That's it.

Most homeowners get their custom recommendation within one business day — no phone tag, no showroom visit.

Takes about 3 minutes to complete

We had talked to three other solar companies and felt like just a number. West Coast Solar walked us through everything. Our bill went from $310 down to under $20.
