One Connecticut homeowner found an unexpected alternative to a whole-home generator in a leased Tesla solar-and-battery system.

The resident claimed that, after a planned buyout, it would cost roughly half as much as a quoted generator installation. They took to Reddit's r/TeslaSolar forum to share their story.

Here's what to know

According to the original poster of the Reddit thread, the main reasons they leased their home energy setup were affordable backup power and virtual power plant incentives.

OP wrote, "My plan is to make the payments for five years and then exercise the buyout option. I had also recently received a quote for a whole-home generator with installation, and it was roughly twice the cost of the Tesla system after the buyout."

The Tesla setup included a 12-panel solar installation paired with three expansion packs and a Powerwall 3. After one commenter asked, "Are 12 panels enough to fill up essentially 4 batteries?" the OP responded, adding, "I keep at 80% grid charging off, no issues. My goal is to have a backup for outages, so even if I don't generate enough to offset cost I'm ok as it is still cheaper than a whole house generator."

Much of the discussion in the thread stemmed from Tesla's reputation as a solar and battery installer. But even after OP wrote that they "genuinely have nothing negative to say" about Tesla, another user explained that "I've heard a lot of positives during the initial planning and installation [about Tesla] and system works great for several years. It's when something breaks in the middle years while warranty is still active where I hear the disturbing support stories."
