Aviva loved her one panel wall-mounted solar hot water system so much, she called us back a few months after we installed it to ask us if it would be possible to add a second panel. Our answer: "Of course!".
One of the great things about solar hot water systems is that you can easily add a second panel to increase the amount of hot water you produce throughout the day. By doubling up on panels, Aviva now makes about 20% more hot water than with her original one panel system. Not a bad idea, considering her family is growing!
