    By Felicity Carus - 16 October 2012, 10:00

    Business transactions are very often about relationships — the solar industry is no exception. But have plunging prices of PV thrust upon the nascent global market by the Chinese really spoilt the industry with too much choice? Has the young bachelor industry been too busy speed dating with $0.65/Wp panels at the expense of a stable and more meaningful relationship between investor, developer and consumer expectations of a quality product that is going to stand the test of time?

    Elon Musk has almost single-handedly driven advances in electric vehicles in the US with his company Tesla Motors. I’ll go out on a limb and say that without Tesla, Ford and GM wouldn’t have paid too much attention to electric vehicles. But the denizens of Detroit got wind of the auto-upstart. Tesla has not yet balanced the books since its extremely successful public offering in 2010, but its stock trades are around three times that of Ford and well above GM.

    A 100lb punch bag, sandbags and a ball bearing the size of your fist are not necessarily what you would associate with state-of-the-art testing for solar panels. But at UL’s solar laboratories in San Jose, California, these experiments that look like they were cooked up in an eccentric inventor’s garden shed, put panels of all flavours through their paces on safety testing before they reach the US market.
