I was very confused with all the ads for solar on TV and all the different companies. I was pleased when I called Hello Solar, they were completely different to the other companies and weren't just trying to sell me any system. They took time to assess my needs and recommended the system that is perfect my household and my family. They also suggested that I go for a bigger system so that I could enjoy more savings but also future proof my home from more expensive electricity bills. I decided to do that and was happy that I was advised that it was optional and advised, but not necessary. Very happy with my decision.
