Actually, most will get the full amount, just not all at once. Unlike the Federal credit, any entitlement not used in the current year is carried forward and may be used against next year's tax, and again the following year and so on, up to five years.

Anyone who can afford a 600h is likely making over $100K per year and liable for $3500 or more per year in State income tax.

True, most will not get the full amount this year but higher income taxpayers can easily use it all in 3 or 4 years.
