RE: Renewable energy - An investment in my future: My solar-array figures update
well, the battery option would probably save you a lot more. but then if you have the space you do not need the expensive lithium batteries and you can have a shed full of the saline type. Big and clunky but they are a lot cheaper and do the job just as well
We've considered adding a battery, the Tesla one, but at this stage it's cost-preventative, especially since we may only be here for another couple of years. We're happy with the 75% at the moment and could improve it with another 4-6 panels however we're mindful of the cost of adding them considering the uncertain timeframe we will be here. We'll demolish the house when we leave and so any capital works would probably be wasted.
It would be cool to be off-grid though.
Thanks for your comments.
If you have a DIY attitude and space, don't go Tesla. You can do something that works better and has way more storage.
I'm demolishing in a few years so I'm not injecting any more capital into works here. My wife's uncle and aunt live 100% off grid though and it would be cool. We go to visit a lot. Such a good lifestyle.
Definitely not worth the investment then. These are long term investments and really don't have a lot of re-sale value when you go to sell the home. People don't think a lot about operating costs (at least here) when they buy.
I considered setting it up here then relocating it to the next place but it didn't make a lot of sense to do so and seemed like a lot of hard work. We plan to set up storage at the next place, along with a larger array than we have now.
