Solar + Heat Pumps: The Electrification Bundle for Multifamily
Solar alone is a revenue line. Solar plus heat pumps is a full building-electrification play — with rebates that often cover the delta.
Why they compound
Heat pumps triple the electric load per unit. That load absorbs more of your on-site solar production, meaning less low-value grid export and more high-value on-site consumption. NOI per kWh generated goes up.
The IRA overlap
- Heat pump rebates: up to $8,000/unit for low-income properties, $2,000/unit for market-rate under 25C.
- Combined with 30% ITC on solar, out-of-pocket net cost on an electrification retrofit drops 40–55%.
Where it works
Older gas-heated multifamily in cold-climate cities (Chicago, Boston, Minneapolis) where gas rates have risen sharply. The tenant sees lower total energy bills; the owner sees lower vacancy from a modernized amenity.
Where it doesn't (yet)
Buildings on utility-billed master-meter gas with structural retrofit costs above $6K/unit. Wait for the tenant turnover before doing full electrification.
