St. Louis publishes no contractor license list we can check, so this list counts permits only. Ask for the license number and check it with the state before you hire. Typical job is the middle job value written on their permits, which can differ from the final price.

Get quotes from up to 3 solar installers

Five quick questions. We send your request to up to 3 contractors who work near you, and email you who they are.

You decide who to hire. Your details go only to the contractors you pick. How we use your details

1. Where is the job?

We match contractors who work near it. We never ask for your street address.

2. What do you need?

Pick any that fit.

3. When do you want to start?
4. What is your rough budget?

A range is fine. It helps contractors reply with a real number.

5. Where should we send it?

Your contact details go only to who you pick here.

Sent. We have your request.

Over the next few days we email you up to 3 contractors who fit, and pass your request to them. Replies usually come within a few days.

Your job room keeps the request, your photos and every reply in one place, with an assistant that checks prices against city permits. Keep its link: it is the key to your job.

Paying for your solar system

Three common ways. Compare the total you will repay, not the monthly payment.

  • Home equity line of creditBorrow against what your home is worth. Rates are usually lower, but your home secures the loan, and approval takes a few weeks.
  • Personal loanNo collateral and a fast answer. Rates are usually higher and you repay sooner.
  • Contractor financingMany contractors offer a plan through a lender. Get the rate, fees and total cost in writing, then compare it with your bank.
