Before our recent solar Phil explained everything clearly and without “sales hype”. We went with his recommendations then the installation went completely smoothly, on time, all cleaned up after. Top service!



  • It really is a different experience with Formula Sun, in an industry dominated by aggressive high volume sales companies, we offer similar prices, more knowledgeable advice and superior after sales service.
