Tigo Energy's Certified Solar Solution Enters Romania's Surging Renewable Market

MONTEVARCHI, ITALY – February 09, 2026 – Tigo Energy, a prominent provider of intelligent solar and energy software solutions, has officially entered the burgeoning Romanian renewable energy market. The company announced it has secured critical certification for its EI Residential solar-plus-storage solution from the nation's key distribution system operators, including Distribuție Energie Electrică Romania (DEER), Distribuție Oltenia, and Rețele Electrice. The approval covers both single-phase and three-phase configurations, making the integrated system available to installers and homeowners across the country.

This strategic move positions Tigo to capitalize on Romania's aggressive push towards energy independence and decarbonization. By meeting the stringent grid-compliance standards, the company provides a crucial new option for a market that is rapidly expanding and maturing.

Romania's Ambitious Solar Ascent

Romania is currently in the midst of a remarkable solar power expansion. Driven by a national goal to source over 38% of its energy from renewables by 2030 and achieve net-zero emissions by 2045, the country has become one of Europe's most active solar markets. After adding a substantial 1.7 GW of solar capacity in 2024, projections for 2025 estimate another 2.2 GW will be installed, pushing the nation toward its target of exceeding 10 GW of total solar capacity by the end of the decade.

A significant portion of this growth is fueled by residential adoption. The number of "prosumers"—homeowners who both consume and produce their own electricity—is skyrocketing, approaching nearly 290,000 by late 2025. This trend is heavily supported by government initiatives. The popular "Casa Verde Fotovoltaice" program, which covers up to 90% of installation costs, is expected to benefit another 100,000 households in its next iteration and now includes subsidies for energy storage. Furthermore, a separate program funded by the REPowerEU plan will offer up to €10,000 per household for installing both photovoltaic panels and batteries for self-consumption.

“Romania is entering a new phase of solar growth, where residential storage and grid compatibility are becoming increasingly critical,” said Mirko Bindi, Senior VP of Sales EMEA & MD Europe at Tigo Energy, in a recent statement. “By working closely with distribution system operators, we ensure that our solutions support grid stability while enabling the continued expansion of rooftop solar through a fully integrated energy ecosystem.”

An Integrated System for Installers and Homeowners

Tigo Energy's market entry is defined by its comprehensive EI Residential Solar Solution, an all-in-one ecosystem designed to simplify the transition to solar energy. The system combines the company's foundational Flex MLPE (Module-Level Power Electronics) products with a line of single-phase and three-phase hybrid inverters, modular DC-coupled battery storage, and the Tigo EI Link, which acts as a central communications hub.

For solar installers, the system's design addresses common pain points. The company touts a commissioning time of less than 10 minutes, a significant reduction that allows for more efficient project completion. This speed is complemented by the Tigo Energy Intelligence software platform, which provides module-level monitoring. This granular data allows installers to remotely diagnose issues, verify system performance, and manage their entire fleet of customer installations efficiently.

To further support its professional partners, Tigo offers a robust support structure. The Tigo Academy provides online training courses, while the Green Glove program offers a white-glove service for installers new to the system, including a professional design review and direct access to technical experts during the first installation.

For homeowners, the integrated system offers a pathway to greater energy independence and cost savings. The combination of solar generation and battery storage allows households to maximize self-consumption of the energy they produce, reducing reliance on the grid and insulating them from fluctuating electricity prices. The system's full backup capability also provides crucial resilience during power outages.

Bolstering Romania's Evolving Energy Grid

The certification of Tigo's solution is not merely a commercial milestone; it is a critical technical validation that speaks to the challenges and opportunities within Romania's energy infrastructure. As renewable sources proliferate, maintaining grid stability becomes paramount. The country's National Energy Regulatory Authority (ANRE) has been actively updating its grid connection regulations to manage the influx of new projects, prioritizing mature developments and ensuring new installations contribute positively to grid health.

Successfully navigating this complex and evolving regulatory landscape demonstrates that the EI Residential solution meets stringent technical requirements for grid interaction. This includes the ability to adhere to new rules that require automated output reduction during periods of grid congestion, a key feature for preventing instability. Tigo's approval provides grid operators with confidence that these distributed energy resources will function as reliable partners rather than unpredictable variables.

This focus on grid compatibility is especially important as Romania scales up its energy storage capacity. The government has set ambitious targets of installing 5 GW of battery energy storage systems (BESS) by 2026 to help balance the grid. By offering a pre-certified, integrated solar-plus-storage solution for the residential sector, Tigo is directly contributing to this national objective from the ground up, empowering thousands of individual homes to become part of a more resilient and flexible national energy network.
