Green Products Has Located an Incredible Low Cost High Output Solar Design
At Green Products, we have come across a product from Cool Earth: Solar Balloons. Cool Earth was created with the mandate of producing electricity using solar power, specifically solar cells. Solar power is not a new concept, but how the sunlight is collected and concentrated is truly unique.
The current installed solar plants use flat-panels. Each panel is heavy, large, easily damaged, and costly to repair. This means the cost to produce a watt of electricity is 5-7 times greater than using natural gas and is not a feasible alternative to fossil fuels. This is no longer true with the Cool Earth solar balloon system.
One side of the balloon is made from reflective silver Mylar plastic. The other half is transparent to allow in sunlight. The silver material is parabolic-shaped to concentrate the sunlight on to a single point to achieve maximum light concentration. This is why high performance solar cells are used.
With the new design comes and the ability to increase sunlight concentration and reduce expensive solar cell material by 300 to 400 times. This cost reduction will bring the price down to a mere one dollar per watt. To give that some context: a typical flat-panel PV(photovoltaic) system on a residential rooftop is about seven to eight dollars per watt.
Each balloon is eight feet in diameter and can withstand over 100 mile per hour winds. The balloons are linked together in series, with the initial installation able to produce 10 megawatts, enough to power 3,500 homes during the day.
One of the areas under consideration is the need to add more peaking power plants, also known as peaker plants. A peaker plant is operational only when demand for electricity is at the greatest, like during the hot summer months. This green product could be used to eliminate rolling brown outages that we have encountered in the past few years.
Some of the more interesting aspects of this solar power station are how simple the design is and how multiples are pulled together to produce a solar power plant. Check it out.
