National Energy Installers

What National Energy Installers does

National Energy Installers (NEI), a Costa Mesa, California-based LLC founded in 2010, is a commercial and industrial energy infrastructure EPC that designs, builds, and funds integrated onsite energy systems. The company combines solar PV (rooftop, ground-mounted, and parking canopy variants), battery energy storage systems, microgrid controls, natural gas generation, EV charging infrastructure, and power distribution (switchgear, transformers, interconnection) into unified energy systems for clients. NEI claims 330+ MW of solar installed across commercial, industrial, multifamily, and residential projects over the past four years and has conducted over 5,000 residential consultations.

NEI serves a diversified vertical set including healthcare, data centers, manufacturing, commercial real estate, multifamily housing, affordable housing, education, and municipal/public sector clients. Its core go-to-market is direct enterprise field sales with dedicated National Accounts Project Developers, supported by a consultative sales motion offering free expert consultations. Revenue is generated through multiple engagement models: one-time cash purchase EPC contracts, recurring-revenue Power Purchase Agreements (PPAs) with zero client capital outlay, and recurring site lease arrangements where property owners monetize land/roof assets. NEI complements its EPC core with financing partnerships (Sunstone Credit) and tax advisory partnerships (RETE-accredited CPAs) to optimize ITC capture under IRA frameworks including FEOC compliance.

The company operates with a small named team of approximately ten officers and directors (CEO Michael Murphy, CIO Christopher Deligiannis, VP National Sales Caden Murphy, SVP Utility Operations Jennifer Murphy, VP Enterprise Sales Paul Holmes, VP Permitting Operations Kris Reaser, Director Engineering Daniel Rincon, Director Office Operations Kelly Sullivan, RME Ryan Cudd, Senior Project Manager Gretchen Cabugao) and is privately held with no disclosed institutional capital, with the Murphy family appearing to hold significant ownership. It holds California CSLB license #1038437, BBB accreditation, and a website (nationalenergyinstallers.com) actively publishing content through 2026.

Direct peers

• Semper Solaris: Semper Solaris is a California-headquartered solar, battery, roofing, and HVAC installer with strong C&I and residential presence. Like NEI, they emphasize integrated energy infrastructure and serve multi-vertical customers across Southern California, making them a directly comparable EPC peer.
• Baker Electric Home Energy: Baker Electric is a long-established Southern California-based solar, storage, and EV charging EPC focused on residential, commercial, and custom home projects. Geographic overlap with NEI (Costa Mesa / SoCal) and a comparable integrated solar+storage+EV offering make it a direct regional peer.
• PetersenDean Roofing & Solar: PetersenDean is a residential and commercial roofing-and-solar contractor operating across the Western U.S., offering integrated roofing, solar PV, and battery installations. Overlap in California C&I and integrated solar-plus-roofing offerings makes it a directly comparable peer.
• Trinity Solar: Trinity Solar is one of the largest privately-held residential and commercial solar EPCs in the U.S., offering a similar multi-state, multi-segment solar-plus-storage installation model. Like NEI, they emphasize engineering-led execution and have an in-house national accounts capability, making them a directly comparable C&I solar EPC.
• Borrego Solar (EDF Renewables subsidiary): Borrego Solar is a commercial and utility-scale solar EPC and developer, now part of EDF Renewables. It directly competes with NEI in mid-to-large commercial solar+storage EPC and shares the engineering-led, project-ownership approach to customer delivery.

Regional players

• Solar Optimum: Solar Optimum is a Southern California-based solar, storage, and EV charging EPC serving residential and commercial customers. Same geographic market (SoCal) and overlapping product portfolio (solar + storage + EV) make it a strong regional peer.
• LA Solar Group: LA Solar Group is a California-based commercial and residential solar installer with experience in multifamily and affordable housing projects — overlapping with NEI's multifamily and C&I rooftop solar focus, though operating at smaller scale.

Others

• Sunstone Credit: Sunstone Credit is the dedicated commercial solar financing partner NEI uses to structure customer loans. As a financing ecosystem participant, it is an enabling peer — not a direct competitor, but adjacent to NEI's PPA and project-ownership value proposition.

Broad incumbents

• ENGIE North America (Distributed Solar & Storage): ENGIE is a global energy services and distributed generation incumbent that develops, owns, and operates commercial and industrial solar, storage, and microgrid projects across the U.S. — directly overlapping NEI's C&I solar+storage and PPA-driven business model.
• Tesla Energy: Tesla Energy offers solar, Powerwall storage, and Megapack utility-scale storage products plus commercial and industrial installations. As a much larger incumbent with hardware (panels, batteries) and a national footprint, it competes with NEI in commercial solar+storage, though at very different scale.
