Does Solar on a Rental Property Improve Tenant Retention? The Data Says Yes.

Every property manager knows turnover is the most expensive line in the budget. So what happens when tenants get a 20% utility bill reduction baked into the lease?

Why turnover is the real enemy

Industry average turnover cost: $3,800–$5,500 per unit when you include lost rent, make-ready, and leasing commission. On a 100-unit property with 50% annual turnover, that's $190,000–$275,000 a year disappearing into the floor.

A retention improvement of just 5 percentage points pays for almost any amenity upgrade you can think of.

What we're seeing across NOI properties

Properties live on the platform for 12+ months show:

+6.4 pp improvement in renewal rate vs prior 24-month trailing average
-11% average tenant utility burden (the bill they actually pay)
+14% increase in 90-day positive rent collection (correlated, not necessarily causal)

The headline tenant outcome: 15–25% lower utility bills. That's not a small "rewards program" win — that's $40–$80 a month back in their pocket every month.

Why solar drives retention specifically

It's a daily benefit. Unlike a gym they never use or a package room they barely visit, the lower utility bill shows up every month.
It's portable framing. Tenants tell friends. "My building has solar; I pay less for electricity." That's organic leasing.
It survives rent increases. When you push rent 4% at renewal, the solar savings cushion it. Renewals close faster.

How to position it in the lease

Best practice: include solar enrollment as a default opt-in in the lease addendum. New tenants sign as part of move-in. Existing tenants get a one-pager and a magic-link enrollment. Take rates we see:

Default opt-in at move-in: 92–96%
Active opt-in (existing tenant rollout): 78–85%

Either is dramatically higher than typical "energy program" enrollment, because the value prop is concrete and the friction is minimal.

The retention story for your investors

If you're raising or refinancing, NOI uplift from solar is the line that gets attention. The retention story is the one that makes the NOI line credible. Show both.
