About time too! The sooner the PV installation industry matures and gets concerned about quality installs of high performance units at moderate prices the better.
Unsustainably high installation rates are just inviting the cancellation of subsidies before the industry matures enough (a smaller number of larger and more financially and technically robust installers) and PV prices decline enough (20% decline for each doubling of module production with cooling installation demand as subsidies are reduced in Europe have returned prices to the long-term downwards trend line www.solarbuzz.com) for PV to be an automatic 'must have' for every new house/shop/warehouse builder.
Average factory gate prices for crystalline silicon modules are now $1.50 US (pvinsights.com). Allow 100% for balance of system and installation and prices are $3000/kW giving lifetime electricity cost in southern Australia of around 17cUS/kWhr, already competitive on a substitution basis with mains power in Australia at about 21cAUD/kWhr.
A moderate Feed In Tariff (equivalent to the retail peak electricity price to reflect PV's time of production) and the industry is pretty much set.
