Project Solar Additional Costs (Adders)

Solar Adders Explained

Our quoting calculator is accurate in most situations, but every solar project is different. In about 20% of jobs there are a unique "adders" that can add cost to the job total.

When purchasing solar it is important to do your research and to know your costs. We do our best to be as transparent as possible by providing upfront quotes without having to talk to a sales person. 

Our quoting calculator already includes the base rates below and is based on the address provided. All other prices are NOT already included and would need to be added to your total cost manually. These costs below are listed at full rate, before the federal incentive, so true net cost will be 30% less. 

If you are unsure if an adder applies to you, our team will let you know before the contract is signed and before any money is committed.
