In Pitesti, Romania, a solar panel installer is trying to build a new kind of power company. It starts with a gateway device that monitors a rooftop’s output, and ends with a virtual power plant (VPP) that treats a thousand scattered solar systems as a single, dispatchable asset. For founder Alex Nicoară, it’s a logical, if ambitious, climb from selling kilowatts to managing megawatts.
Solmag launched in 2021 as a straightforward hardware business, manufacturing and installing photovoltaic panels for homes and businesses around Pitesti [PitchBook, post-2021]. By 2024, it had rolled out a digital marketplace to connect those customers with installation partners, a move aimed at building what it called "the largest community of prosumers in Europe" [Energynomics, April 2024]. But the company’s Delaware-registered entity, Solmag Inc., points to a grander plan: a smart gateway that turns individual solar systems into grid-balancing tools, aggregated into a VPP that can sell power back to utilities during peak demand [F6S, post-2021].
From panels to a power plant
The pivot from installer to grid operator is a story of stacking business models. The first layer was physical,panels on roofs, with the associated site scans and project planning. The second was the marketplace, which charged installation partners 2,495 euros for 100 qualified leads [Energynomics, April 2024]. The third, and most capital-intensive, is the VPP layer. Here, the company sells a hardware gateway that connects to a home’s solar inverter, monitoring generation and consumption in real time. When aggregated, these devices form a virtual power plant that can be called upon by grid operators to provide capacity during stress events, like a heatwave [AI for Founders, 2026].
The early traction signal is modest but tangible: the company reported orders for over 300 of its IoT gateway devices following launch [CB Insights, post-2021]. For a VPP, each device represents a potential revenue-generating node. The unit economics, at least on paper, are compelling. Instead of a prosumer simply selling excess solar back to the grid at a low, regulated net metering rate, the VPP model aims to sell that same power at a premium during peak periods, splitting the revenue.
The founder’s calculated climb
Alex Nicoară, the CEO, is a serial founder whose path informs Solmag’s staged approach. His first venture was a cleaning services app called Cleany.ro, which later rebranded to Zumzi.com [Business Review, 2026]. That company reportedly grew to 26 employees and $400,000 in annual recurring revenue before being sold to an investor [2050hub.com, 2026]. He then invested $100,000 of his own capital to bootstrap Solmag, initially launching the solar panel marketplace [2050hub.com, 2026]. His co-founder, Iasmina Florina, is a second-year electrical engineering student at Politehnica University of Bucharest, bringing technical grounding to the hardware side [LinkedIn, Iasmina Florina, 2026].
The company’s funding has been a patchwork of accelerator support and founder capital. It participated in the Black Sea ClimAccelerator and received investment from IdEA Bucharest [PitchBook, post-2021]. Public records indicate a 2022 accelerator round of $293,000 [PitchBook, post-2021]. In 2024, the company was reportedly seeking a 500,000 euro investment for a 5% stake, implying a target valuation around €9.5 million [Energynomics, April 2024].

The grid-balancing bet
The core of Solmag’s future thesis rests on a simple imbalance: the grid needs flexible capacity, and rooftop solar owners have underutilized assets. A VPP solves for both. The company’s gateway device, compatible with various inverters, is the data-collection point [Solmag.ro, 2026]. The software layer then aggregates hundreds of these points, creating a profile of available capacity that can be offered to grid operators or energy traders. When demand spikes, the VPP can remotely signal participating systems to feed power back to the grid, earning revenue that is shared with the prosumer [AI for Founders, 2026].
This isn’t a novel concept in Silicon Valley or Berlin, but in Eastern Europe’s evolving energy markets, it’s less crowded. Solmag’s first-mover advantage would be its dual presence as both the installer that puts panels on roofs and the software company that manages them afterward. The risk, however, is that it’s attempting to master three distinct businesses at once: construction, SaaS marketplace, and utility-scale energy trading.
Where the wheels could come off
The ambition is vast, and the risks are layered. Building a VPP requires not just technology, but regulatory savvy and deep utility partnerships that a small Romanian startup may struggle to secure. Furthermore, the company’s public goals are exceptionally bold, including plans to franchise its platform in 18 countries, with each franchise generating a target of 20,000 euros per month [Energynomics, April 2024].
- Execution complexity. Managing a hardware supply chain, a two-sided marketplace, and a grid-balancing service simultaneously is an operational triathlon few early-stage teams complete.
- Regulatory hurdling. Energy markets are among the most heavily regulated. Navigating grid interconnection rules and securing contracts with transmission system operators is a non-trivial barrier.
- Capital intensity. The VPP model requires scaling the installed base of gateways before it becomes a meaningful grid asset. This demands significant upfront capital for hardware and customer acquisition, beyond the scope of accelerator grants.
The company’s answer appears to be a stepwise approach: use installation and marketplace revenue to fund gateway deployment, and use a growing network of devices to prove the VPP model to investors. It’s a capital-efficient theory, but the margins in installation are thin, and the leap to utility sales is long.
The next twelve months
For Solmag, the immediate milestone is converting those 300 gateway orders into installed, grid-connected units that can begin generating aggregated data,and, eventually, revenue. The company will also need to close its targeted 500,000 euro funding round to fuel this hardware rollout and further software development [Energynomics, April 2024]. A successful pilot with a regional grid operator in Romania would be the most convincing proof point, moving the narrative from device sales to active grid participation.
The back-of-the-envelope math is where the dream either crystallizes or evaporates. If Solmag’s 300 gateway orders represent an average 5 kW system each, that’s 1.5 MW of potential aggregated capacity. In a high-demand period, that block of power might be worth a premium of, say, €200 per MWh over the standard rate. One activation event could generate €300 in grid revenue, shared with prosumers. The model only works at scale,thousands of systems, not hundreds,but the unit economics point in the right direction.
Ultimately, Solmag isn’t just competing with other solar installers. Its true incumbent rival is the traditional utility itself, and the entrenched, centralized model of grid management. To win, it must prove that a distributed, digitally orchestrated network of rooftops can be more than a curiosity; it must become a reliable, bankable source of power.
