So, I guess at first it started with the app. You see the great part is with the app is that yeah, you can view your output and your input and you can adjust your consumption during all parts of the day. And you can monitor it from you know, holiday if you're on holiday with a family, right through to being in the office or sitting in the house with the air con on. We also have the capability of monitoring each individual panel and obviously at all parts of the day so we do see which halves or which parts of the roof have the bigger outputs and at times you can readjust your installation if you have to. So what made us choose the system in particular was definitely the warranties, definitely the make of the panels, and also the support that you get. You're getting a better panel you match it with a superior inverter that is done by a great installer and it's all hand in hand. So we have a complete superior system on the roof and also the customer service is second to none.
