Under a lease, pricing typically starts with a base payment, then increases by a contractual escalator, often around two to three percent annually, though zero-escalator options exist. A PPA instead multiplies actual solar generation by a negotiated cents-per-kilowatt-hour rate, sometimes with a production floor or cap. Checking whether pricing includes maintenance, monitoring, and inverter replacements matters deeply. Ask how taxes, city fees, or utility bill adjustments might affect your final cost. Request a side-by-side, twenty-year cash flow so you can visualize year-by-year differences, not just the first month.
With both structures, the provider typically owns the system, claims federal tax benefits, and handles maintenance, while you pay for electricity or a monthly fee. This arrangement can reduce upfront costs but shifts decisions about equipment and service schedules to the company. Confirm whether the provider registers a UCC filing on your property records for collateral. Identify who handles warranty claims and roof penetrations. Ask if you must trim trees to protect production. Understanding roles prevents finger-pointing later, and helps you plan for roof replacements, shade changes, or unexpected service events over decades.
