The country is also becoming an increasingly attractive destination for photovoltaic park investments. However, this rapid growth highlights a major challenge: the lack of sufficient energy storage capacity, a key issue for the national energy system, warns Kilowat, a green energy solutions company.
The demand for photovoltaic power plants is rising, both through self-financed projects and subsidized programs. The Casa Verde initiative has played a crucial role in expanding green energy adoption, helping to lower energy costs over time. With the scheduled removal of the energy price cap on April 1, more Romanians are turning to solar energy to reduce expenses and secure their energy supply. Rising electricity tariffs have further accelerated interest in renewable solutions, particularly in the residential sector, where solar panels are becoming a smart long-term investment.
Once the price cap is lifted, most Romanians will have to pay market rates, with only vulnerable consumers eligible for financial aid. The state currently owes energy suppliers 8 billion lei in compensation for past price subsidies.
“Funding programs like Casa Verde, RePower EU, and ElectricUp 2 are keeping the photovoltaic sector in high demand, generating more projects in 2025 than in previous years. More customers are realizing the importance of working with experienced installers who will still be around 15-20 years from now. However, a key factor shaping the market will be whether energy price caps continue. Higher demand could lead to an increase in solar panel prices, so Romanians should consider installing them while costs remain reasonable. We expect a strong year ahead, though not without challenges. Businesses are also increasingly aware of the need to cut energy costs and become self-sufficient, as seen in the growing interest in Electric UP and AFIR programs,” said Albert Soare, founder of Kilowat.
A major obstacle in 2025 will be Romania's limited energy storage capacity. While photovoltaic expansion continues, storage solutions remain underdeveloped, impacting grid stability and efficiency. Lithium-iron-phosphate (LiFePO4) batteries are emerging as the preferred residential storage solution, offering greater safety and efficiency compared to traditional lithium-ion batteries.
“In 2025, we anticipate advancements in storage technology and lower battery prices. Energy storage is becoming a top priority, and Romania is working hard to address this gap. The entire renewable energy sector depends on integrating storage solutions. In the residential market, LiFePO4 batteries are gaining traction as a safer and more efficient alternative to lithium-ion, particularly in terms of fire safety,” explains Soare.
To support this transition, Kilowat is introducing advanced energy storage and conversion technologies to Romania, including Livoltek inverters. Additionally, ENPHASE microinverters and batteries, developed in the U.S. with contributions from Romanian inventor Nelu Mihai from Silicon Valley, are enhancing solar energy conversion efficiency. These microinverters enable direct AC production, eliminating conversion-related risks and improving overall performance.
Wind energy is also evolving, with new developments and the integration of mixed wind capacities expected.
Romania continues to make strong progress in transitioning to renewable energy. The country remains attractive to investors, and new photovoltaic parks are expected to become operational this year. The high public interest in reducing energy costs is further fueling the sector's growth.
Kilowat has installed solar panels for over 3,000 residential and corporate clients, with more than 2,000 of these projects completed through the Casa Verde program. For Casa Verde 2024, the company anticipates an increase in managed projects. It also installs solar systems for individuals financing their own energy solutions and businesses leveraging the Electric UP program or other funding sources.
Founded by the creators of SanoVita, Kilowat is among Romania's leading renewable energy solutions providers. With a team specializing in solar consulting and installation, the company offers comprehensive services, from sales and installation to energy storage solutions and post-installation maintenance. Kilowat has completed projects in both Romania and Germany.
The company holds ANRE authorization for medium voltage design and installation and is certified to install Huawei, Deye, Livoltek, Growatt, and Sungrow systems. It collaborates with authorized metal support suppliers such as K2 Germania, Aerocompact, and Grup Simex.
Kilowat also provides online system monitoring, performance optimization through software updates, and technical adjustments for maximum efficiency. With a dedicated after-sales support team, the company ensures long-term, reliable operation of photovoltaic installations.
