I am planning on keeping my Model 3 at a second home where I only drive it on alternating weekends. The home is a condo with a long (200 feet+) run from my meter to my carport. Including permits, I estimate that the cost of running power conduit and placing a 120V outlet at my carport would be about $2,000. A 240V 14/50 NEMA outlet would cost more and would be overkill for my situation. As an alternative, I was thinking I might be able to install a solar panel on the flat carport roof and use that power to charge my M3 battery during the 10 day intervals while I am away. I am in California with good sun most of the year. Any advice on the feasibility and cost of doing this would be super helpful. Thanks!
