Starting 1 July 2025, Bulgaria’s solar energy sector will be hit with a sharp rise in environmental taxes, placing them among the highest in the European Union. A new report from the Bulgarian Association for Electrical Engineering and Electronics (BASEL) highlights the sweeping changes set to affect the cost of solar energy systems, including photovoltaic panels, batteries, and inverters.
The eco fee, currently set at around 2% of a product’s value, will surge to 16%. This increase far exceeds the usual rates in other EU countries, where similar environmental fees typically range between 0.3% and 3%. The steep rise is expected to significantly drive up the overall price of solar system installations across Bulgaria.
BASEL attributes this dramatic change to actions taken by private recycling firms rather than government policy. Three of the four companies in Bulgaria authorized to manage the recycling of solar equipment have simultaneously raised their service fees tenfold. This move, made without official regulatory backing or a clear explanation, affects the alternative system through which importers and manufacturers can pay eco fees directly to recyclers instead of through state channels.
The impact on households could be substantial. BASEL estimates that for a standard rooftop solar setup of 15 panels, the eco fee will increase from the current 25–45 euros to as much as 200–360 euros. Since most residential systems in Bulgaria require between 15 and 20 panels to meet energy demands, the cost burden on homeowners will be significant. The higher fees will also apply to other key components like inverters and batteries, further raising the cost of complete solar installations.
Experts warn that this increase in environmental taxes could deter investment in renewable energy, slow the growth of solar technology adoption, and place additional financial pressure on individuals and families aiming to transition to cleaner energy sources. As the deadline approaches, stakeholders are calling for more transparency and potential regulatory intervention to avoid long-term setbacks in Bulgaria’s clean energy transition.
