What Eltex does

Eltex Solar, S.L.U. is a Barcelona-based residential renewable energy installer founded in 2021 that delivers turnkey solar photovoltaic systems to homeowners across 75 cities in Spain. The core offering is rooftop solar self-consumption installations, with bill savings of up to 70% (up to 90% when paired with battery storage and behavioral changes) and a 6-9 year amortization period against 30+ year panel lifespans. The product portfolio has expanded beyond solar into modular lithium battery storage (up to 5.1 kWh per module, 20+ year lifespan), air-source heat pumps branded as aerotermia (COP 3.5-4.5, ~75% less energy consumption than gas boilers), and European-made 22 kW wallbox EV chargers, all unified under a proprietary iOS/Android monitoring application.

The business operates on a direct-to-consumer model, generating leads through the eltex.es website with a free energy assessment (estudio gratuito) and assigning each customer a personal advisor who manages the full lifecycle from technical visit through permitting, installation, and post-sale monitoring. Components are sourced from Jinko Solar (panels), Pylontech (batteries), and Hisense (heat pumps), with financing facilitated through partnerships with ABANCA, Cetelem, and Sofinco (BNP Paribas Personal Finance) to enable €0 upfront offers. Revenue is generated primarily through one-time installation fees, with the Colab referral network paying up to €500 per closed deal as a secondary acquisition channel.

Eltex has completed more than 3,000 installations, holds a 4.5/5 rating from 925+ Google reviewers, operates in three website languages (Spanish, English, Catalan), and is reported to have saved 3,000 tonnes of CO2. The company employs 51-100 people, is headquartered in Barcelona's Sant Martí district, and closed a $2.1M funding round in December 2025 led by Vireo Ventures with participation from kopa ventures.

Direct peers

• SolarMente: Spanish residential solar installation startup focused on self-consumption, batteries, and EV chargers for homeowners. Closely matches Eltex's product mix, target customer, and direct-to-consumer go-to-market in Spain.
• Holaluz: Barcelona-based residential solar and green energy retailer operating across Spain. Holaluz directly competes with Eltex in Spanish residential self-consumption installations and offers bundled solar + battery products with similar digital-led customer experience. Most comparable peer given shared geography, customer segment, and product focus.
• Ecooo: Spanish renewable energy cooperative offering residential solar self-consumption installations. Comparable in targeting Spanish homeowners for distributed solar generation with a similar bundled product approach.
• Efecto Solar: Spanish residential solar installer operating across multiple Spanish regions, offering turnkey solar panel and battery installations for homeowners. Directly comparable product offering and target customer in the same Spanish market.

Others

• Factor Energía: Independent Spanish electricity retailer offering renewable supply contracts to homes and SMBs. Adjacent rather than directly competitive, but increasingly moving into self-consumption and EV charging services that intersect with Eltex's proposition.

Emerging players

• Plenitude (Eni): Eni's retail and renewable energy subsidiary expanding residential solar and heat pump offerings across Europe including Spain. Comparable in targeting the same residential decarbonization stack (solar, batteries, EV charging) at an earlier stage of Spain market penetration.

Broad incumbents

• EDP Solar (EDP España): Portuguese-Spanish utility with a residential solar offering in Spain. Competes with Eltex as part of a broader utility portfolio spanning generation, supply, and emerging residential distributed energy services.
• Repsol (Solar / Waylet ecosystem): Spanish integrated energy major with growing residential renewable energy and EV charging offerings. Competes with Eltex as part of a broader downstream energy, mobility, and home services portfolio.
