I was very enthusiastic about getting solar on the property I purchased. I thought I had researched very well and was up with what I needed for my property. Turns out I knew pretty much nothing. The property was old and needed a lot of electrical updating including underground cabling, new switchboards and more. The electrician was also a solar installer and I was going to get him to install a 10 kw system on the garage was the roof was renewed.
I wanted the system for independence. The money saving was secondary. I thought the solar could provide power if the grid went down but it turns out the solar system relies on the grid (although there are inverters rolling out that can supply some power recently). So without a battery there is no independence and batteries are not recommended at this time.
I was told that I would get my money back in 6 years or less which sounds promising until I spoke to other people I knew who had solar. Two were told they could not put back into the grid because the grid couldn;t handle it. They were told this after they installed and are unlikely to ever get their money back.I then found out that during winter (I am all electric including heating) the standard system of 6.6 kw would only supply enough for my hot water with a 9.6 kw allowing for a bit more use but during summer I would have copious amounts of electricity that I don’t need to feed back into the grid. So basically I am producing electricity for the grid more than myself, no independence and no guarantee the grid will accept my excess. Then the government suggested charging for putting electricity back into the grid and cutting off in peak times (when I finally have some power being produced). It was the death knell on my dream of having solar panels.
I am not suggesting I would never entertain installing again but it was unlikely. I did get a change over switch fitted so if the power goes off I can run the house on a generator.
