RE: The Economics of Solar

I look at it purely economically in my own situation. I spent $22,500 in September last year for a solar and battery system here in Australia. It lets me go off grid and still have power (and charge the battery) in a black out. Could be self-sufficient if I'm careful with energy usage. That self sufficiency is more important as far as I am concerned, compared to the cost, but I am very happy with the costs prevented so far.

So far, since 9 September 2024, I've not spent $2692.54 due to real time usage and exports, and due to using the battery when the sun hasn't been shining, I've not spent a further $814.80

Furthermore, I've gotten a rebate of $980 for installing the battery, and various energy retailer credits of $200, and $150 of grocery gift cards (as a sign on bonus)

So, in less than a year, I've not spent $4837.34 out of my savings.

In less than one year, I've "paid off" 21% of the system. It feels like the best investment I've ever made.
