3. Upkeep, if you own it

InverterString inverters usually last 10 to 15 years; replacing one costs about $1,000 to $2,500 installed. Microinverters usually carry 25-year warranties.

With a string inverter we count one replacement around year 12, about $2,000 in today's dollars.

The roof will need replacing in the next 25 yearsRemoving and reinstalling panels for a new roof costs about $200 to $300 per panel, or $1,500 to $6,000 for most homes. We count it around year 15.

How the check works

Every offer is turned into the same two numbers: what each kWh of solar power costs you over the contract, and what it saves on your bill. If it saves more than it costs, the deal is good. We also show what the same system would cost to buy at the median 2026 price of $2.57 per watt, so you can see what the leasing company is keeping.

Exported power counts for less in many states now, so we use your state's credit rules. If the system includes a battery, we count the power it moves to the evening, and leave its price out when judging the panels' price per watt. If you'd own the system, we count its upkeep too: a replacement inverter around year 12, and new-roof costs if you expect them. A lease or PPA company pays for its own repairs. Totals are shown as you'd pay them and in today's dollars. How the numbers work.
