Not fast enough as in pushing households to combat climate change when the main reason is systemic on a national/global scale not to mention countries who aren't on board at all and create way more damage?

With batteries down 80-90% cost/ increased efficiency and many states in the US adopting incentives (In my state you can get them installed for little to no cost) we are making great progress.

The angle on this shouldn't be targeted at whatever income your family makes and a single household impact but at the main sources or governments that'll effect those changes.
