I thought about that. But recently evaluated panels on my 3000sqft home and the cost was $16k. Assuming that average installations are for less capacity, an average of $10k increase would probably not impact new house construction. Especially since the cost is offset by low energy payments and increase in home value.
Increase is home value is not always desirable, especially if you are tight securing a mortgage. With higher interest rate, this is going to be a no-no real soon.
