Say WHAT??Quite frankly, the environmental benefits of building solar into a grid-connected home is questionable as well, as you're generating electricity at a time when the grid has more than enough electricity available.
If the avg. US elec bill/yr = $1000 give or take and the avg. US elec used/yr = 8000 kwh give or take this thing pays for itself in one year.When solar panels are available for less than $1 a watt (and trade price is not far from that already for some amorphous panels) we're going to see a huge takeup of solar for these sorts of applications.
Yes, there is an unlimited supply of coal, wood & oil in/on the Earth :whistling2:My personal belief is that the future of solar is not for powering big homes in California or the like - I suspect that this will never be a cost effective solution at any time in the future
i am doing this exact thing, and I think you have GREATLY under-estimated the cost of running AC electric to a shed. For my application, as in your example, going solar will show an immediate return on investment. The downside is I won't be able to run an aircompressor, or a beer fridge out there, but I will have lights inside and out, and i'll be able to keep a charger for my cordless tools out there as well. i have a charger that plugs into a 12vdc cig lighter, and am going to use 12v LED lighting, so i don't even need an inverterLet's assume you have a shed at the bottom of the garden and you'd like to fit a security alarm and some lighting. The cost of running a power cable down the garden is likely to cost you $100 by the time you've included circuit breakers, fittings and so on. A solar electric system is likely to cost you a similar amount, and of course you're keeping away from high voltage electricity, which makes it simpler and easier to install.
And how big of a battery array would be needed to power a fridge?Not really... you store the power in a battery and use it when you need it. That way your battery can charge up during the day and you can use the power whenever you want it.
It also means that you can have a smaller panel than you'd need for instant power without a battery, because the solar panel would be trickle charging the batteries every day.
