    Craig,

    What evidence have you of “plummeting prices” ?

    Prices are actually increasing due to a number of factors, the obvious being prices can’t keep going down forever!

    The cost of manufacture solar panels is beginning to increase as a result of supply chain prices, and labour component in installation.

    Another factor slowing the rate of installations is the reduction or termination of utility tariff fees and sunset clauses in local state and federal subsidies.

    You can’t simply parrot the same old out of date information, without sooner or later looking desperate.
