I've worked as an electrical engineer for some time and it's worth talking about energy use and what you can do to save money.
How can I reduce my power bill? Here in Australia Solar PV has been a booming industry for many years now, but is it worth the cost of having solar panels put on your roof? How many should I get? And battery storage, what about that?
Well let me hit you with easy to understand answers to those questions, and then I will go on and on about the reasons why and some projects you can take on to squeeze more bang for your buck out of your energy use.
- How can I reduce my power bill? Use less power.
- Should I get solar panels? Yes, have solar PV installed.
- How much solar should I get? Minimum 1.5kW but more than 3kW is diminishing gains.
- Should I get battery storage? No, battery storage is not currently worth it.
Okay they were big bold statements and let me reinforce again that is is about saving money - If you want to go off-grid for instance due to remote location or being a prepper - you have to have battery storage. If you are a power head and want to boast, you'll need more than 3kW.
