Solar panel prices were up 30 percent for orders placed in March compared to a year earlier, while prices for AC cables, also used for solar panel installations, are as much as 75 percent higher compared to levels in 2019 and 2020, Dr. Stelios Loumakis, president of SPEF, the Hellenic Association of Photovoltaic Energy Producers, has pointed out.
In response to these higher costs, the SPEF president called on authorities to abandon any thoughts of reduced tariffs for new solar energy projects currently being developed.
Installation costs for XT/MT substations have also risen considerably, up by 20 percent over the past year, according to Dr. Loumakis.
In addition, power grid operator IPTO’s connection term costs have also risen to levels double those of a few years earlier.
These connection term increases are not exclusively linked to higher-priced equipment but also to network upgrades being carried out by IPTO in order to boost capacity, projects whose cost is passed on to investors.
