Prysmian – PRYSOLAR, the Group’s new PV cable solution
What is PRYSOLAR, Prysmian Group’s innovative PV cable solution presented at Genera 2023?
On the occasion of Genera 2023 – the International Energy and Environmental Fair held in Madrid last February – Prysmian Group has launched Prysmian PRYSOLAR, the most innovative cable solution for solar power generation.
But what are solar cables, why are they so relevant and, most importantly, what is Prysmian PRYSOLAR?
What are solar cables and why are they important
Solar cables, also known as solar photovoltaic cables or solar PV cables, are specifically designed cables used in photovoltaic systems, in which they play a critical role: solar cables are used to transmit the electrical power generated by solar panels and serve as a conduit where the electricity travels, connecting the components of the whole circuit and ensuring the efficient and safe flow of power and hence the effective functioning of solar power installations.
Solar cables are thus crucial to provide a safe and reliable performance of any photovoltaic system, since their failure disrupts power generation.
What is Prysmian PRYSOLAR?
As stated above, solar PV cables play a key role in power generation. Nevertheless, extreme climate events like heavy rains and floods may cause cable deterioration and failure with negative consequences on power generation capacity, reliability of power supplies and return on investment.
To face and overcome these challenges, Prysmian Group has launched PRYSOLAR cables, the most innovative PV cable solution, fully compliant with the applicable global standards EN 50618 and IEC 62930 and enhanced with long term resistance in water up to 1800 V DC. Thanks to an innovative and first-in-the-industry test protocol that certifies long term resistance in water for DC cables, in fact, Prysmian PRYSOLAR offers extreme climate strength and +30-years lifetime.
The characteristics of Prysmian PRYSOLAR
Given the important role solar photovoltaics play in the fight against climate change (since they are crucial to achieve carbon neutrality targets), and given that global photovoltaic capacity is set to increase to 19000 GW and cover more than 50% of global electricity demand by 2050, it is essential to provide PV systems with innovative solutions in order to face the most unpredictable challenges and events that could affect the areas where solar panels are installed.
And that’s exactly what Prysmian PRYSOLAR is designed for. Thanks to its characteristics, this innovative solution provides:
- Extreme climate strength
- Reliable return on investment (+30 years of lifetime)
- Increased operational efficiency of assets
- Sustainable supply chain
“Solar photovoltaic generation is set to cover more than 50% of the global electricity demand by 2050. Return on investment, asset efficiency, OPEX and Levelized Cost of Energy are the main and most critical priorities for our customers in the solar industry. Prysmian PRYSOLAR, is the new generation of cables designed to provide our solar customers with peace of mind in these areas.”

Nevertheless, they are critical system components, and their failure disrupts power generation. Utility-scale solar farms are growing in size and operating voltage, and the geographical areas where they are installed are more and more subject to extraordinary climate events: extreme and unpredictable. Extreme climate events like heavy rains and floods may cause cable deterioration and failure with negative consequences on power generation capacity, reliability of power supplies and return on investment.

More information on EN Standards: https://www.en-standard.eu/ + European Standards is an expression of requirements for products, processes or services to meet the requirement of fitness for a particular purpose.
EN Standards have got a positive impact on facilitating the free movement of goods in international trade, seeking to rationalize production, helps to promote environmental protection and competitiveness, ensuring adequate consumer protection in the Internal Market.
Currently, EN qualified technical recommendations are not binding and their use is voluntary.
EN standard, such as publicly available documents, is accessible at all stages of formation and use in practice.
These European Standards, unlike legislation, which may occur without consultation and consent of all the concerned documents, when addressing fundamental questions agreed upon by all stakeholders.
EMR Additional Notes:
- EN 50618:
- This European Standard applies to low smoke halogen-free, flexible, single-core power cables with cross-linked insulation and sheath. In particular for use at the direct current (d.c.) side of photovoltaic systems, with a nominal d.c. voltage of 1,5 kV between conductors and between conductor and earth. The cables are suitable to be used with Class II equipment. The cables are designed to operate at a normal maximum conductor temperature of 90 °C, but for a maximum of 20 000 hours a max. conductor temperature of 120 °C at a max. ambient temperature of 90 °C is permitted. NOTE The expected period of use under normal usage conditions as specified in this standard is at least 25 years.
- AC (Alternating Current) & DC (Direct Current) & UC (Universal Current):
- Direct current (DC) is an electric current that is uni-directional, so the flow of charge is always in the same direction. As opposed to alternating current, the direction and amperage of direct currents do not change. It is used in many household electronics and in all devices that use batteries.
- Direct current has many uses, from the charging of batteries to large power supplies for electronic systems, motors, and more. Very large quantities of electrical energy provided via direct-current are used in smelting of aluminum and other electrochemical processes.
- in contrast to AC power, DC power is entirely made up of active power, meaning that there are almost no losses due to the capacitance of wires when DC power travels long distances. In fact, high voltage AC transmission systems have losses of 7% to 15% with aboveground transmission.
- Alternating Current is used in homes as Direct current can not be easily stepped up or stepped down with the help of transformers whereas alternating current can easily be converted from low voltage to high voltage or vice-versa with the help of transformers.
- “UC” is used for “Universal Current”, that translates to “either DC or AC”. So a 24 V UC input can accept either 24 V AC or 24 V DC.
- CapEx vs. OpEx:
- Capital expenditures are a company’s major, long-term expenses while operating expenses are a company’s day-to-day expenses. Examples of CapEx include physical assets, such as buildings, equipment, machinery, and vehicles. Examples of OpEx include employee salaries, rent, utilities, and property taxes.
- The levelized cost of energy (LCOE), also referred to as the levelized cost of electricity or the levelized energy cost (LEC), is a measurement used to assess and compare alternative methods of energy production.
- The formula to calculate the LCOE is (Present Value of Total Cost Over the Lifetime)/(Present Value of All Electricity Generated Over the Lifetime).
- LCOE is the metric selected to represent typical electricity generation cost elements in a common framework including project finance (FCR), capital expenditures (CAPEX), fixed and variable operations and maintenance costs (FOM and VOM), and annual-energy-production-per-kilowatt plant capacity based on capacity factor, …
- Lower LCOE is better. The project could be profitable if the LCOE is lower than the maximum power price the plant can get. On the other hand, the project will probably not be economical if the LCOE is higher than the cost of power.
