Why No Taxes?
Going granola doesn’t stop at environmental awareness. At Teragy Solar, we’re dedicated to cultivating a company worth existing. A company who’s focus isn’t purely based on profits and growth, but customer experience, environmental impact, and reliability. This is why our sales goals always come second - and with that, comes tax savings we pass on to you.
As a yearly special, we pass our tax savings down to our customer. Based on state published sales tax and nexus laws, we keep track of our sales in every state. As long as our sales are below your state’s taxable threshold, you are exempt from paying sales tax. We do this extra work, to help lighten up your project budget. Need more details?

Buy today and save now. This “No Sales Tax” special expires as soon as we reach your state’s tax threshold.

How is shipping handled?
Shipping and freight costs are calculated at final check out. Shipping costs associated to equipment shipped outside of freight are final. Freight shipping costs will be finalized after the sale, as freight costs can vary based on destination, weight, size, and season. In the event freight shipping costs surpass estimated costs, a Teragy Representative will call to assist in paying the rest of the balance.
