The whole issue is energy storage, whether batteries, heat storage or whatever.
Tesla's solar tiles still need a lot of work.
roy is correct. The break even on costs is the problem.
Either the energy storage has to improve, the install cost has to drop, or both. In the last 4 months I've showed two clients that the numbers just don't work. Even with tax credits.
Currently the only thing that works/pays off is when installed as part of new construction which also requires the rest of the bldg to be super efficient. And that barely works. Rehab installs just don't make the numbers.
