Exploring the Romanian Solar PV Market: Project Dilemmas Amid Opportunities

In recent years, the Romanian solar PV market has entered a period of rapid development. Driven by the EU Recovery and Resilience Facility (RRF), the energy crisis, and rising electricity prices, the market has shown a significant growth momentum in the past 2-3 years. Large-scale ground-mounted solar PV parks of 50MW-200MW have become the mainstream of the market. The country is fully deploying renewable energy to reduce its dependence on natural gas, and the investment return rate of solar PV projects continues to rise. However, behind the rapid development of the emerging market, there are many difficulties restricting project implementation: insufficient grid capacity leading to queuing for grid connection of large-scale power stations, cumbersome and time-consuming approval processes involving multiple departments, lack of experience of local construction teams in wiring large-scale power stations, unstable supply chains for high-specification solar PV cable procurement, coupled with capital dependence on EU subsidies and slow fund arrival. These problems have jointly become the "roadblocks" for the advancement of the Satu Mare solar PV park project.

As a key local new energy project, the Satu Mare Solar PV Park has a planned installed capacity of 50MW and requires a large number of high-specification solar PV cables that meet EU standards, covering the entire scenarios of DC side series connection, AC side step-up power distribution, and control and communication. The core dilemmas faced by the project party are: queuing for grid connection may lead to delayed project commissioning and shorten the investment return cycle; complex approval processes increase time costs; non-standard wiring by local construction teams is prone to rework; high-power cables have special specifications, and the local supply chain cannot guarantee delivery time; the power station is large in scale, resulting in high difficulty and cost of later operation and maintenance; slow arrival of subsidy funds leads to prominent cash flow pressure. After multiple screenings, the project party finally chose GERITEL, mainly recognizing our comprehensive advantages of "product compliance + customized solutions + full-process services" and rich experience in undertaking similar solar PV projects.

Why Choose Us? Dual Support of Compliant Certification and Product Advantages

The core premise for the project party to choose GERITEL is that our products fully meet EU standards and have

(Certificate No.: B 126326 0001 Rev.00) — this means that our solar PV cables do not require additional compliance testing, can be directly adapted to the local power grid in Romania, greatly shortening the project preparation time and avoiding rework risks caused by non-compliant products. This is also one of our core competitive advantages distinguishing us from other suppliers. In addition, the full range of solar PV cables we customized for the project needs achieve precise matching in performance, specifications, and adaptability, fully meeting the power station construction needs.

The core product adapted for series connection inside the DC side solar PV array is the H1Z2Z2-K cable, which adopts tinned copper conductors. Compared with ordinary copper conductors, the tin-plated layer can effectively prevent oxidation and extend service life, adapting to the long-term outdoor operation of solar PV power stations; both the insulation layer and outer sheath are made of XLPO weather-resistant materials, with outstanding UV resistance and high-temperature resistance. The long-term working temperature can reach -40℃~90℃, which can easily cope with the four-season climate changes in Romania and avoid insulation aging and sheath cracking; the common cross-sectional areas are 4mm², 6mm², and 10mm², with a rated voltage of 1kV DC, which accurately matches the DC transmission from solar PV modules to inverters. The transmission loss is reduced by more than 30% compared with ordinary DC cables, reducing later operation and maintenance costs.

In the AC side step-up and power distribution link, we provide two types of core cables: low-voltage (LV) power distribution cables adopt the YJV model with specifications of 3x70mm² and 3x95mm², and medium-voltage (MV) cables have specifications of 3x150mm² and 3x180mm², with a rated voltage range of 10–35kV, which can perfectly meet the needs of connecting the AC power output by the inverter to the step-up substation and the national power grid. Both types of cables adopt XLPE insulation materials. Compared with traditional PVC insulation cables, they have stronger temperature resistance (long-term working temperature ≤90℃), excellent insulation performance, anti-aging and anti-cracking properties, and are smokeless and halogen-free when burned, making them more environmentally friendly; the sheath is made of PVC or PE weather-resistant materials, which are wear-resistant and corrosion-resistant, suitable for outdoor buried or overhead laying, adapting to the complex outdoor environment of the power station, while reducing energy loss during long-distance power transmission and improving grid connection efficiency.

The control and communication link adopts the H05VV-F European standard flexible cable, with a multi-core copper conductor design. The common specifications are 2×1.5mm² and 4×1.5mm². The good flexibility facilitates complex on-site wiring, greatly reducing construction difficulty and time; it is mainly used for power station monitoring systems and inverter status collection, with stable low-voltage control signal transmission and low loss, helping the project party to grasp the power station operation status in real time and providing convenience for later operation and maintenance. In addition, all cables are produced in a standardized manner with clear color distinction (black for DC side, gray for AC side, and blue for control and communication cables), compact structure and light weight, which not only facilitates construction distinction, but also reduces transportation and construction costs. At the same time, they have strong mechanical strength, which can resist outdoor mechanical damage and extend service life.
