I was wondering if building a solar-powered system in the future would deal with the factory based issues I have
Any thoughts
I have no immediate plans to do this but might consider as a long term solution

I have thought about it too . I think people who have done it complained about crap inverters being noisy.
Maybe it is possible to build a solar system that is optimised for audio, i don't know. Technology moves so fast.

Thanks for that Stu

Mr Nangle is/was involved in solar energy instalation. I know he suggested it as a way of bypassing mains problems for hifi, but then he would say that on a hifi forum in his position!

Cheap inverters will generate either squarewaves (like many computer UPS) or poor distorted sinewaves. In either case, it'll be worse than the problem you're trying to resolve.
An alternative is to rig up a DC solar system if you were to buy all hi-fi components that run on, say, 12V.

So much yet to be discovered on this
I'm guessing we will have to run on battery or battery/mains before too long

The thing is, High voltage AC is the most efficient form of power transmission. DC could only be local, never distributed at any kind of reasonable cost.

I think local generation is coming for most of us, sooner rather than later

Agreed.

You could use solar to charge batteries then feed the various supercap and linear power supplies. You'd need to mod the power supplies to get rid of the mains TX etc. Your class D amps help greatly due to their efficiency.
You could just use batteries and charge from the mains...

I'll be well behind the leading edge Clive. Let a few others blow things up and iron out the wrinkles  |

An alternative is to rig up a DC solar system if you were to buy all hi-fi components that run on, say, 12V. Thats what i thought. A DC system in the home would be ideal. Throw away the transformers and rectifiers. Each piece of equipment could have it's own reservoir capacitor and regulators to drop the voltage to what ever is needed. If the DC source voltage was adequate then the power amp output stages could be run without regulators. Several DCsupplies that are isolated from each other would be ideal so ripple from one piece of equipment does not pollute another. |

Yep, and Class D power amps would be ideal for getting the most from the voltage.

We will all have Teslas batteries in our garages before long anyway.

I'm half planning a sizeable personal solar farm at the bottom of the garden.
There are some mega ones around here.
Pays better than arable / livestock I guess, add sheep or Alpacas (if you are posh), to trim the grass around them..

I always saw the payback time far too long
From memory about 20 years. By which time they need replacing

Were the panels subsidised ? |
