Home rooftop solar is expensive. California incentives were advantaging the wealthy while the working poor were unable to use them. When these wealthy landowners hooked up the solar they got taxpayer-subsidized deals on, they were reimbursed at the retail rate for the energy they sent back into the grid. This meant power companies had to raise rates that mostly the working poor were paying for electricity.
Reducing the amount of new rooftop solar installs because of fewer incentives that only benefit the wealthy isn't dealing a blow to renewable energy (it's a drop in the bucket of renewable energy). It's dealing a blow to taxpayer-funded inequality.
Solar only makes sense in large arrays. It just doesn't make financial sense, except as a luxury, to install them on homes.
