Understanding solar savings for rental property
When the tenant pays utilities
When tenants pay utilities directly, the landlord typically doesn't see the bill reduction. Instead, value comes through a rent premium for a lower-cost, solar-equipped unit, or from an improved property valuation. A $40 monthly rent premium, growing 2% a year, totals about $15,375 over 25 years. The solar panel calculator is the quickest way to check whether the system size behind this estimate fits your roof and usage.
When the landlord pays utilities
This happens in situations where the landlord pays the utility bill directly, common in all-bills-paid rentals, multifamily buildings with shared meters, or short-term and furnished rentals. In that case, savings work the same way as for an owner-occupant, potentially over $61,000 over 25 years for a typical system. See the lifetime savings calculator for that full math. Utility rates drive the whole savings calculation, and the US Energy Information Administration's electricity data track them state by state.
A note on tax treatment
Tax treatment of solar on rental property can be complex, and rules differ for owner-occupied versus business or rental use, including depreciation options that don't apply to a primary residence. This tool does not attempt to model those benefits. Confirm your specific eligibility and any available deductions with a tax professional before making a purchase decision. If your production estimate feels uncertain, the real world vs nameplate output gap calculator gives you a second check on annual output.
Other value beyond savings
Solar can also support property value and marketability. See the home value increase estimator for how solar may affect resale or appraisal value, which applies to rental property as well as owner-occupied homes. If you plan to sell within the payback window, the resale payback recapture calculator is also worth checking. The US Department of Energy's homeowner's guide to going solar walks through the same decision step by step.
