Solar Energy

One of the core applications of CTS technology is in the renewables sector
CTS technology can be used for grid connections from solar farms


For the solar industry, 2020 was a record year with 144 GW of new installation outperforming all other renewable sources, despite the COVID-19 crisis.

Solar energy is considered the ‘New King of Electricity’. With continuously improving technology and falling hardware prices, solar photovoltaic (PV) becomes the key energy source of the future. The economy of scale motivates solar energy developers to build bigger utility-scale solar farms on cheap to rent land. Often these locations are distant from existing network infrastructure requiring long cable connections.

Given the importance of maximising the amount of available renewable energy in the mix, it makes sense to use the most efficient cable possible to export power from the solar farm to the grid. Enertechnos’ CTS cable with lower losses than conventional cable can help to deliver more clean energy and to improve the return on investment of solar projects.

Many countries across the world consider solar energy as a key source for decarbonisation. This is particularly because it will benefit developing countries that are located around the equator where there is the highest solar radiation density.

It has been estimated that 500x500km of the Sahara Desert covered by PV panels can deliver enough solar energy for the world population. To achieve net zero, the International Energy Agency estimates that the world has to reach 630 GW a year of new installations in 2030, where 70% of that capacity is expected to be utility-scale solar farms.

In order to connect all these solar farms, over 50 thousand km of medium and high voltage cable will be required where CTS can play an important role.

Benefits of CTS for Solar Energy

CTS lowers transmission losses up to 20% while increasing revenue and delivering more value to solar developers

Lower cross section reduces leakage current that often limits utilisation of cable during low sun radiation (clouds, morning and evening). This can increase the annual solar farm output by up to 20%

Lower use of copper reduces the carbon footprint of solar energy and preserves environment that could be damaged by mining minerals

CTS cable can deliver the same power by lower cross section reducing costs of cable by up to 30% and need for raw materials

CTS cable can deliver power over long distance at lower voltage reducing need for additional higher voltage equipment
