yeah thats a good point! some solar is cheap and you can use it as roof tiles, it depends not only on what you need it for, but where you need it!...so if you got a BOL built and ready for living, then you could utilise a couple of these, for instance the roof tiles, or even solar paint (yep thats in the works, give it a year or 2, also transparent solar film to put on windows!)
