My friend, who lives in the hills in Los Angeles shares a long driveway with other houses. The LA DWP just did their site map, as they require before a customer can install solar. They said the install would require an upgraded power line. My friend was quoted 30K to dig a 250 foot trench from his power meter to the street to house this new line. I'm don't know if Tesla quoted this or DWP. As is, due to this unexpected cost increase, he plans to abandon the install. Have any of you encountered this situation? Do you have recommendations about how my friend might reduce this cost.
