    my apologies I meant tile as well - was failing to multitask.

    Slate frequently lasts longer if the bed is good(used to live in a slate roofed house). Tiles crack more often.

    Though shingles (they mean the asphalt ones not Cedar) are from fossil fuels and guess where most of our asphalt comes from Tovarich?

    Though Cedar which are both beautiful and fairly green can last 50 years apparently.

    Metal has 50 years but cooking panels isn't a good idea.

    Even if some of the tiles fail internally so long as the configuration is redundant the output will just fall. So you may not need a new roof any sooner. Also being plastic and probably on a flat baseboard decent external insulation should be easier.

    Tesla are offering a 25 year guarantee.

    Now US roofs are more likely to be shingle and last 30 years

    Now I suspect placing flat slate like tiles on a backing like ply / tile backing would be the most economical way to create a solar roof. Tiles would probably be flatter and less likely to move.

    Yep.

    Thanks to someone posting the energy dashboard link I started looking it all up.

    So I'm going to invest my profits from dirty energy into cleaner energy, and I shall be able to look my younger relations in the face.

    Edited to say: my own utility supplier is a green energy electricity supplier to the grid. They were amongst the cheapest with best customer service and the least chance of going bust when I changed to them. Now I'm stuck with them....

    Also get an inverter with a passive heat sink and install it in a cool place such as a garage as the ones with fans chew quite a lot of electricity

    The Tesla wall is a nice design, but like most designs, it's form over function at a price.
    Yeah I guess, depending on how much hot water you use. The long and short of it is that between hot water tanks, house batteries and perhaps car batteries there should be no need to feed energy back into the grid, and every kwh harvested can be used. Come to that, I'd rather mine dogecoin with my excess than give it back to SSE. Time to pull the lever on some panels I think - I've got massive south facing roof space.

    Another point is that once we all move to EVs, we'll have 20-30+kwh of storage sitting in the drive. Obviously you can divert any excess energy into that, rather than get whatever pitiful feed-in tariff is on offer, but also I believe there are ways to use the car as a battery for the home electrics as well - or even to function as part of a distributed grid.
    Even if it ended up costing me more (certainly in the short term) I'd love to get off grid and stick a couple of fingers at the energy companies. No doubt they'll bring in legislation to try and stop us soon, as I think they have done in Aus and US.

Then pull the plug on gas and electric so I don't have to pay the standing charges..

    That's what a Tesla Powerwall system gives you .....

    For most home owners that is not the case, you'll want to boil the kettle, or cook something, which will cause a big increase in your demand. During the day the requirements will be enough to run a computer or two. In the evening, add in the lights. Don't forget your fridge/freezer/iron/central heating/hot water.

    But yes, if you set up a separate circuit for the steady demand stuff, you could run that efficiently on a suitable generator.
