Floating Solar

Floating solar energy opens up new opportunities for energy transition

Floating Solar is nowadays the third pillar of the global solar PV market!

Large-scale conventional PV plants usually require huge areas of land to generate commercially viable green electricity and land acquisition. Site preparation issues associated with traditional solar installations are by-passed now. Besides, in most cases, floating solar allows power generation to be located much closer to the areas where the demand for electricity is higher.

 

Making this way floating solar technology an attractive option for countries with high population density and competing uses for available land, or simply where water is an abundant asset and often disregarded.

 

 

In addition, the strict emission-control regulations set, the huge demand for land for various purposes, as agriculture, and the rising need for cheap electricity are driving to the growth of the installation of PV panels in regional waterbodies. And scale matters when it comes to all-in costs for floating solar applications, so larger floating solar projects will lead to lower all-in costs on a dollar-per-watt basis.

 

Floating solar has become a new, reliable and cost-effective solution to turn water bodies into solar power plants for the production of cleen energy, while conserving land, without competing with agricultural activities.

Floating solar installations are easier and faster to install and remove than other similar PV installations. They’ve withstand tougher conditions and are more efficient than other solar plants due to the water’s cooling effect mostly, that helps to reduce thermal losses. 

 

Nowadays there are more than 400,000 square kilometers (km2) of human-made reservoirs in the world, suggesting that floating solar has a theoretical potential on a terawatt scale, purely from the perspective of the available surface area.

Having it’s advantages in consideration, Universal Kraft is one of the pioneers in the technology and have already gained knowledge in this area with over 230 MW of designed projects

Floating Solar

Some challenges exist as well in floating solar installations, including for example the lack of a long- standing track record on the possible effects on water quality  besides complications related to the anchoring and mooring and the relative complexity of maintaining some parts of the installations – electrical components in particular, which may require some  insulation. But despite these engineering challenges, floating solar offers significant opportunities for the global and local expansion of the global solar energy capacity installed. 

  

How it works?

1.
Mounting System

The mounting system for floating solar is designed to keep the equipment stable due to the impact of weather conditions (such as wind and water flow). In addition, the system is used to connect PV module panels and other parts of the solar floating system.

2.
PV System

PV Generation equipment is used, mostly crystalline solar PV modules.

3.
Underwater Cable

The underwater cabling is used to transfer generated power from the waterbodies to the substation.

4.
Mooring System

The mooring system is a permanent structure used to halt the movement of the floating solar installation in the water. This allows us to adjust the water level fluctuations while maintaining its position in a southward direction.

The design of the anchoring and mooring systems, which are used to keep in place the floating platforms, will always depend on a wide range of factors such as water level and its variability, bathymetry,  soil conditions, float type, and wind load for example.
