The government giveth and the government taketh...an industry propped up with government subsidies can not and will not survive. Look at the areas that are saturated (in HECO eyes) with PV...all expensive neighborhoods where people pay high taxes then get tax breaks for going green. Middle and lower class don't pay high taxes (if at all) so they don't benefit from the subsidies. 
I do give credit to the "believers" for always trying and hanging in there...but not on my dime thank you.
