What you get
What does a Westhaven estimate include?
- The right battery, not just the right panels. Today the math works when you store your own power and use it instead of selling it to the grid for pennies. So your estimate includes the battery matched to your home, with the specs and the cost laid out next to the solar, not bolted on later.
- Every option for your home in plain English, not just the one we'd sell.
- A design modeled on your roof and usage. Never a template.
- The production number we're prepared to put in a signed Power Guard contract.
- Time to decide on your terms. The homework is yours to keep.
