Thank you for your question. We understand that the renewable energy 'world' can be a bit uncertain and many energy companies make 'green' promises they can't keep. That's why we've made sure SmilePower is verified by external auditors. This means they ensure that what you've consumed at your site, we've matched in generating the same amount of renewable energy. We also comply to Australian Government Standard ASAE 3000, for that bit of extra assurance.
