Solar Islands concept by CSEM
Transcript of Solar Islands concept by CSEM
By: Dhruv Amin
Their are many ways to make Renewable energy
Wind Turbines, Water Turbines, Tidal, Solar Chimneys/Solar Towers and one of them is Solar Islands that is going to be new and has a fresh design
The Solar Island™ platform is compatible with Concentrated Solar Power (CSP), Solar troughs Fresnel mirrors (STFM), Low Concentration Photovoltaics (LCPV), and Photovoltaics (PV)
The Advantages and Disadvantages
The History of Solar Technology Around The Globe
Each of the 100 solar panels on the islands are positioned at a 45 degree slope. The entire island can then rotate 220 degrees in the direction of the Sun to adjust the amount of solar energy it can harness throughout the day. This entire idea has been here since 2008 from a Swiss researcher called Thomas Hinderling.
So what is a Solar Island?
It's a concept made by a Swiss company called CSEM ( Centre Suisse d' Electroniqueet et de Microtechique), Its French
The Types of Solar Island Panels
The azimuth of the sun is a horizontal angle of the sun. This prevents the shadowing of other technologies, a problem that would affect other solar technologies. Since there is no shadow the full sun’s heat gets transferred to the solar technologies, at least 30% more than other solar technologies.

This Island can float or be built on land
Solar Islands have a diameter of 5km and the height is 20m, solar panels also heat liquid to make water vapor
The Dome at the center contains water which produces steam in pipes and also leads to that plant
The solar islands can rotate a total of 220 degrees in the direction of the Sun to gain more solar energy.
1. Thermo-solar panels are placed on a membrane
2. Solar Panels turn to the position of the sun
3. The steam is stored in a high pressure steam tank to produce electricity
4. Then the underwater pipeline takes steam to shore or tankship
5. Where steam turbine uses the steam to generate up to one gigawatt of electricity
6. Overpressure enables floating of membrane 20 meters above sea or land level
7. Water channel ensures airtight connection
Circular Floating Torus
The Efficiency of the Solar Islands is about 10% to 20%, but about 80% of energy is lost
Solar towers have Full tracking (they follow the sun light), but 70% space lost
Solar Troughs have Elevation tracking (they follow the sun light), 50% of space lost
Dishes have Full tracking (they follow the sun light), but 80% of space lost
These are all the different kinds of Solar Island Panels there can be
In 2009 a prototype was launched (started building) in Dubai, from that achievement a Swiss energy company called CSEM invested £70 million. They decided to build three solar islands on Lake Neuchâtel in Switzerland.
The company says that the solar islands will be installed on the lake nearby the (Lake Neuchâtel, Switzerland) marina. So in 27th February 2013 they built a prototype.
25 meters in diameter and is used as a laboratory to test concentrated solar power (CSP) technologies.
CSP plants concentrate sunlight onto boilers to produce steam, which is sent via a pipeline to a shore-based plant where it drives steam turbines, which generate power.
Pros of Solar Islands
The cost per kWh is 5 times lower because a low-EFC type panels can be used. The thermal principle allows to store energy, so energy can also be supplied at night. The water that is used to generate electricity and the cooling is an abundant substance. It can be built anywhere: Land or Water. Raw materials used in making electricity are in abundance that is water and sunlight. Sun tracking for more efficiency is also available.
Cons of Solar Islands
The money that has been invested into this project is huge. The cost includes the construction and also the equipment needed for the islands is huge. On top of that the price of repair is high if a natural disaster occurs and some areas in the world do not receive so much Sun light necessary for solar panels
From solar energy to electricity the efficiency is between 10% to 20%. The Solar islands has a radius of 1.5km and only 6.4 square kilometers active surface giving 1.5tWh per year of electrical energy (1.5 billion per year) it can power up to 137 to 150 houses per year if each home uses 10,908kWh per year (the average of american homes) It depends on how much you use. Most countries are shown interest towards this idea. The company of CSEM has founded a company called Nolaris Inc. Nolaris Inc. is in start-up mode, but the company has potential contracts in Malta, Qatar, Chile, and Tunisian. One has already been built in Dubai and its very efficient for it to be over their because of the hot sun.
