Solar Purchase vs. Solar Lease in Walnut Creek
Compare the two paths most buyers and property owners weigh before moving forward locally.
System Ownership (Direct/Loan)
Usually the better fit when you want a simpler path, tighter short-term cost control, or fewer moving parts during the decision process.
Power Purchase Agreement (Lease/PPA)
Usually the better fit when long-term performance, durability, or a stronger upside matters more than the lowest upfront number.
