LONGi Solar and Globenergia publish 2025 PV Market Report reflecting shifting motivations, maturing technology and the rising visibility of Back Contact solutions

LONGi Solar and the Polish renewable-energy publication Globenergia have published the new national study “Photovoltaics in Poland. Voice of the Industry and Prosumer 2025.” The report is based on 723 survey responses, including 414 prosumers and 309 industry representatives, and provides a detailed picture of a market undergoing structural change. The results show that the number of new PV installations continues to grow, but at a noticeably slower pace compared with previous years. At the same time, several indicators point to a more mature market: around 27–29 percent of single-family homes already have a PV system, purchasing decisions increasingly prioritise technology, performance and durability over price, and both installers and prosumers rate their knowledge of core system components such as PV modules, inverters and energy storage as good.
Growth in Poland continues, but the market is clearly slowing compared with earlier years

The report records 1,582,629 micro-installations by August 2025, up from 1,526,123 in January 2025 and 1,392,821 in January 2024. This confirms continued expansion, but at a much lower pace than in previous periods. For context, the increase between 2021 and 2022 exceeded 83 percent, while growth between January and August 2025 reached only 3.8 percent. The report describes this as a shift toward stabilisation and maturity, not a decline in adoption.

Prosumer saturation limits the speed of further expansion

An estimated 27–29 percent of single-family homes in Poland are already equipped with PV systems. With nearly one in three suitable rooftops generating solar energy, the pool of first-time residential customers is naturally shrinking. As a result, market dynamics increasingly shift toward system upgrades, storage integration and optimisation of existing PV systems.

Prosumers show significantly more stable and positive sentiment compared with 2024

Prosumers assess the situation of photovoltaics in Poland more positively than in the previous year. In 2024, 33 percent described the situation as “very bad”; in 2025 this fell to 12 percent, with most respondents now choosing “average”. The report highlights several factors that contributed to the poor perception of the PV market in 2024. These include regulatory uncertainty, changes in support programmes, widespread dissatisfaction with the net-billing settlement system, a slowdown in new grid connections, rising prosumer saturation, and increasing price pressure across the sector. In 2025, this picture has become noticeably more stable. Only 12 percent of prosumers now describe the situation as “very bad”, and most respondents rate it as “average”.

Net-billing is the most significant barrier to new installations

For 62 percent of prosumers, net-billing is the main discouraging factor when considering PV investment. Installers similarly rank net-billing as a major barrier, often alongside uncertainty in legislation and permitting. Concerns relate to the predictability of returns and the complexity of the scheme, and the report identifies regulatory clarity as a key need for future growth.

Installers face price pressure and fewer orders, shaping a cautious industry outlook

Industry respondents most commonly identify intense price competition (40 percent) and a decline in orders (35 percent) as current market realities. This reflects a challenging environment in which companies increasingly rely on efficiency improvements and service differentiation. Despite this pressure, the majority plan to continue operating in the sector, signaling resilience.

Support schemes remain central to sustaining investment

Both prosumers and the industry strongly value public support. 93 percent of installers call for the continuation or redesign of “Mój Prąd”, a government grant programme launched in Poland to help households install small-scale renewable-energy systems. It aims to increase prosumer participation and support the country’s transition toward distributed energy.
74 percent of prosumers believe that financial support schemes for households should remain in place. Public funding remains the most influential driver of PV adoption, ahead of equipment prices or access to installers.

Choice of technology, performance and durability increasingly outweigh price in system selection

Prosumer decision-making is becoming more technologically informed, and the report shows a clear shift toward high-performance module architectures, including Back Contact (BC) solutions. Technical performance and efficiency now rank as the most important criteria for prosumers (27 percent), exceeding price (21 percent). Installers confirm the same trend, noting that customers increasingly evaluate modules based on long-term durability, degradation behaviour, and real-world energy production, particularly in low-light conditions.

Market shifts highlight increasing awareness of Back Contact technology

The report also indicates a rising presence of Back Contact technology in the Polish market. In the technology overview, the study states that Back Contact modules are gaining a growing share, largely due to their high efficiency, strong performance during morning and evening hours, and superior operation under diffuse light. Installers’ technology recognition data further supports this tendency: Installer awareness of IBC and HJT + Back Contact hybrid designs remains at an early stage, yet the growing recognition of these technologies indicates that Back Contact solutions are already present in the Polish market and steadily gaining visibility. Additionally, 13 percent identify modules with built-in shading optimisation, a feature the report explicitly links to BC/IBC architectures, noting that shading-optimised modules are “directly associated with IBC/BC design principles”.
Taken together, these findings demonstrate that the market’s growing emphasis on performance, reliability and advanced functionality corresponds with increased awareness and adoption of Back Contact solutions, which align closely with the attributes prosumers and installers now prioritise.

Energy storage adoption is becoming mainstream

A substantial 66 percent of prosumers either own or plan to install a home energy-storage system. Typical household batteries range between 8–15 kWh, often combined with EMS solutions that increase self-consumption and help navigate net-billing dynamics. This marks a notable shift toward greater energy independence and system integration.

Operational issues are mainly linked to grid conditions rather than equipment failures

The most frequently reported issues stem from external factors: over-voltage shutdowns (17–20 percent) caused by local grid constraints, and WiFi or inverter communication problems (14–20 percent). Component failures remain relatively rare. Importantly, 52 percent of prosumers report no issues at all, reflecting high equipment quality and improving installation standards.
Knowledge levels are high in core technical areas but weaker in regulatory topics
Installers and prosumers consistently rate their knowledge of PV modules, inverters and energy storage as “good”, demonstrating strong familiarity with essential PV technologies. Knowledge is less robust in dynamic tariffs, construction rules and grid-connection procedures, which respondents view as complex. These gaps reflect the continued need for clearer administrative and regulatory guidance.

Daniel Moczulski, Sales Director CEE, LONGi Solar (DG), concluded: “This year’s study confirms a decisive shift in the Polish solar market. Households now assess photovoltaic systems with a far more mature mindset, looking beyond upfront cost toward the stability, performance and long-term value of their installation. That evolution reflects a market that is no longer driven by early-adopter enthusiasm, but by clear expectations for quality and reliability. We also see the first signs of the next technological cycle. Back Contact architectures are still emerging in Poland, yet their growing visibility among installers shows that the market is opening up to higher-efficiency solutions. For LONGi, Back Contact is not an experiment, but the strategic direction of our global R&D. We are committed to bringing this technology into mainstream adoption, raising both the efficiency and resilience of rooftop systems across the country.”
