Is Sunrun or Tesla cheaper for solar?▼
Tesla is generally cheaper on a per-watt basis for purchased systems ($2.00-$2.50/W vs $2.50-$3.50/W). However, Sunrun's $0-down lease eliminates upfront costs entirely. Total lifetime cost favors Tesla if purchasing, but Sunrun's lease requires no financial commitment.
Does Tesla still offer solar leases?▼
