Sell a Commercial Solar & Battery Storage business

Owner-operator commercial solar & battery storage businesses trade at 2.5x–4.5x SDE for typical $500K–$3M SDE ranges. At $3M+ EBITDA scale the same operators sell at 5.5x–10x EBITDA. Multiples in this category are ebitda-based and data-sourced from AGC / FMI Construction Industry M&A Report 2025 + IBBA Q4 2024. Where you land in the range is driven by growth trajectory, revenue mix, customer concentration, and management-team depth beyond the owner.

Sunnova Business Solutions, Nautilus Solar (Power Sustainable), and PE-backed EPC platforms (Ares Infrastructure, Excelsior Energy Capital) drive commercial-solar consolidation. Active buyer archetypes in construction include National contractor / vertical integrator, Construction PE platform, Family office / long-hold. Which of these bids for your business depends on scale — sub-$1M SDE is typically individual or search-fund territory, $1-3M SDE opens up PE platforms and strategics, and $3M+ EBITDA gets full LMM buyer attention.

Commercial solar and battery-storage contractors with C&I project backlog, IRA-tax-credit-monetization capability (direct pay, transferability), and multi-state EPC capacity trade at premium. Beyond the industry-specific factor, the universal drivers in construction are bonding capacity and clean surety-carrier relationship; multi-year project backlog with reputable gcs / owners; union / prevailing-wage workforce where applicable (or explicitly non-union).

Commercial solar faces material interconnection-queue delays in most ISO regions and shifting incentive economics; buyers scrutinize your interconnection-backlog and PPA-vs-cash mix. Buyers in this category also standardly scrutinize project profitability variance and buried job losses and bonding capacity limits growth. Addressing these in advance in a well-prepared CIM materially reduces retrade risk during diligence.

Typical transaction range for commercial solar & battery storage is $3.0M–$100M in annual revenue. Below that, buyer pool narrows to individual and small-search-fund. Above that, PE platforms and strategics dominate. NAICS code 238220 — buyers screen by NAICS in most deal sources.

From the day you engage a broker to close, expect 6–12 months for a well-prepared business in construction. The prep work — financial cleanup, addbacks documentation, key-employee retention agreements, real estate lease sorting — is where 3-6 months of the timeline hides. Starting that early is what separates a full-multiple exit from a discounted one.
