Solar on a Rental Property: Who Pays, Who Benefits, Who Consents

Solar for landlord-owned rental homes

Solar on a rental works when the person who paid for the panels is the person whose bill goes down, or when the landlord captures the value another way. On most Colorado single-family and duplex rentals the tenant pays the electric bill, so a landlord installing solar is lowering someone else’s cost unless rent, utility billing or the lease is adjusted to match. That’s a deal-structure problem, not a solar problem, and it has clean solutions. We install on rentals across the Front Range and mountain towns, and we’ll walk you through the metering and lease questions before we quote.

Who pays the bill decides who benefits

If the tenant pays Xcel directly, solar reduces the tenant’s bill and the landlord sees nothing on the statement. If the landlord pays utilities and folds them into rent, solar drops the landlord’s cost directly. If it’s somewhere in between — a flat utility fee, a ratio utility billing system — the savings follow the arrangement.

Landlords who add solar to tenant-paid-utility rentals usually recover it through rent: a solar-powered house with a $30 electric bill instead of a $150 one supports a higher rent and a longer-staying tenant, and both are worth more over ten years than the bill itself. Colorado doesn’t cap rent, so the arrangement is a lease-negotiation matter; put the expected bill reduction in the listing and let the market price it.

Meters, duplexes and shared systems

A single-family rental with one meter is the simplest case: the system feeds that meter, and whoever holds the account gets the net-metering credit. A duplex with two meters is harder, because one array can only offset one meter without special tariffs. Options are two smaller systems (one per meter), one system on the meter with the larger load, or moving common loads — laundry, exterior lights, a heat pump — to a house meter the landlord holds and offsetting that.

Xcel and some other utilities allow certain forms of meter aggregation or virtual net metering for multi-unit buildings under specific rules; those programs have changed and have eligibility limits, so verify the current version with the utility before designing around it. For a duplex we most often quote two systems and let the tariff decide.

Tax treatment: residential rules don’t apply to a business asset

A rental is a business asset, and that changes the tax picture. The federal residential credit (§25D) ended for systems placed in service after December 31, 2025, but it also never applied to a property the taxpayer doesn’t use as a residence. The commercial §48E credit and 100% bonus depreciation can apply to solar on rental property placed in service by the end of 2027 (or with construction begun by July 4, 2026, for a longer window), as of September 2026. That can materially improve the return compared with an owner-occupied home.

Whether your specific rental qualifies, how depreciation flows through an LLC, and how it interacts with passive-loss rules are questions for your CPA, not for us. We supply the invoice, the placed-in-service date and the system documentation; the accountant does the rest. Don’t let anyone, including a salesperson, tell you a credit is certain.

Lease, PPA or purchase for a rental

Cash purchase at $2.80–$3.25 per watt plus the business tax treatment usually produces the best return for a landlord who plans to hold the property. A Colorado RENU or Concert Finance loan spreads it over 20–25 years, often below the rent uplift the system supports. A lease or PPA puts the system on the roof with no capital and a monthly payment typically 20–30% below utility rates, but the provider owns the system and the lease transfers with the property at sale, which some buyers dislike.

For a landlord, a PPA has an extra wrinkle: the monthly payment is yours, the bill savings are the tenant’s unless the lease is structured around it. Purchase or loan is simpler to align with rent.

One more contract to read is the tenant’s. Roof work, a panel upgrade, a few days of crew traffic and a utility shutoff for interconnection all need the tenant’s cooperation. Colorado leases generally give landlords entry for repairs and improvements with reasonable notice, but a friendly conversation and a written schedule beat a legal right. We coordinate directly with tenants when landlords ask.

What to do next

1Confirm who holds the electric account (tenant or landlord) and how utilities are handled in the lease.
2Count the meters; for a duplex, tell us which loads are on each and which the landlord controls.
3Ask your CPA about §48E and bonus depreciation for this property and how you hold it.
4Decide how you’ll recover the value: rent adjustment, landlord-paid utilities, or a utility charge in the lease.
5Give the tenant written notice of the install schedule; we’ll coordinate access and the interconnection shutoff with them.

Figures are honest ranges from our Colorado pricing and public data, not a quote. Utility rules and incentives change — we confirm the current ones before any design.

FAQ

Questions we hear

My tenant pays the electric bill. Why would I install solar?

Because a house with a $30 bill rents for more and turns over less than one with a $150 bill. Landlords recover solar through rent or by taking over utilities, not through the bill itself. We’ll show you the expected bill reduction so you can price it into the lease.

Can one solar system offset both units of a duplex?

Not on two separate meters without a utility aggregation program, and those have eligibility limits that change. We typically quote two smaller systems or one system on the meter with the bigger load. Verify current aggregation rules with your utility.

Do I get the 30% residential tax credit on a rental?

No — that credit never applied to non-owner-occupied property and it ended for systems placed in service after 2025 anyway. The commercial §48E credit and bonus depreciation may apply to a rental as a business asset through 2027. Ask your CPA.

Does the tenant have to agree to the installation?

Practically, yes. You need roof and panel access, a day or two of crew presence and a brief utility shutoff. Most leases allow entry for improvements with notice, but a cooperative tenant makes the job faster. We can coordinate scheduling with them directly.

Is a lease or PPA a good idea for a rental?

It avoids capital but leaves you paying a monthly amount while the tenant gets the bill savings, unless the lease passes that through. It also transfers with the property at sale. Purchase or a loan is usually easier to align with rent and with the business tax treatment.

Will solar help when I sell the rental?

A paid-off system is a straightforward selling point, especially to investor buyers who look at operating cost. A leased system requires the buyer to assume the contract, which can slow a sale. We don’t quote a specific value uplift; it depends on the market.
