Wasn't the 100% purchase tax a temporary war-time measure? I believe it settled at 33.33% after the war for luxury goods, and was later reduced to 25%.
In the early days of VAT there was also the 8% standard rate and the 12.5% luxury rate, which at one point was increased to 25% for a while. There was also a ridiculous situation in which an attempt was made to apply a different rate depending upon the intended use of an item, e.g. buy a replacement capacitor for a piece of essential office equipment and it was standard rate, by the same capacitor for your domestic TV set and it was "luxury" rate. How they ever thought that would work I have no idea!
Re food, as I understand it the U.K. and Ireland are the only two EU countries which don't tax it, and was how the zero-rated category came into existence. It wasn't exempt under the (then) EEC VAT rules, but there was nothing to stop them making it taxable but with a rate of zero percent! Last I heard, the EU was still kicking up a fuss about how "unfair" that supposedly is.
But back to solar, the installations I've seen around this area generally use net metering and PG&E credits the customer for anything fed back into the grid. On the lease scheme at the house we were looking at, the solar company also had its own separate meter indicating energy output from the inverters.
