We put Solar panels on the roof of our Marae, which were promised to reduce the bill. At the time, we were not advised that this would raise the price of the main power that we were billed each month and that without a battery there was no real point of having solar panels. Now, that may make sense now!! BUT this was not explained to us four years ago when we purchased the solar panels. We were promised free to cheap power. This has not happened and since then there was no real attempt to help us with our concerns when our power went up. We would not have purchased solar panels, but the person who sold them to us did not care much for our needs. Made the sale and then vanished!
