Should I delete one of them and pair again?"Photo Credit: RedditPhoto Credit: RedditAs a Reddit discussion unfolded, commenters pointed to several possible explanations.Some said the feature did not appear for them until PTO, or "permission to operate," the utility approval that allows a solar system to fully connect to the grid.Others focused on account and device setup, asking whether the vehicle had been paired to the Powerwall and saying Tesla might need to merge two separate sites into one.AdvertisementAdvertisementStill, not everyone agreed.One user wrote, "I haven't had PTO for 13 months now. I use charge on solar everyday."The missing setting may come down to account configuration, site setup, or the timing of utility approval, rather than any single universal rule.Why does it matter?For Tesla drivers with solar panels, Charge on Solar can be a money-saving feature, helping direct excess rooftop generation to an EV rather than drawing as much electricity from the grid.If it is unavailable, homeowners may miss out on some of the lowest-cost charging available: power already being produced on their own roof.Adding battery storage is one of the best ways to protect your home during power outages, lower long-term energy costs, and move closer to energy independence or even going off-grid.

Then the charge on solar appeared."Others suggested checking whether the vehicle is properly paired to the Powerwall and making sure the app has not split the home into multiple "sites."AdvertisementAdvertisementIf it has, they said Tesla support may need to merge them.Several replies also said the feature appeared only after PTO was granted, meaning some customers may simply need to wait for utility paperwork to clear.Get TCD's free newsletters for easy tips, smart advice, and a chance to earn $5,000 toward home upgrades.
