Typically power is priced by Levelized Cost of Electricity (LCOE) where you amortize the total cost of ownership across the total power generated to get a per kwh cost which is what most grid operators care about. After all, large scale investors and governments don't care if a plant costs a billion dollars if it produces 20 billion in electricity.

What you are talking about is the Payback Period (PP) or Return on Investment (ROI) which is more important to homeowners adding a solar plant to their homes.
Both of these types of measure take into account both capital and operating expenses.
