Today, the very best solar power systems can reach an optimum efficiency of approximately 15-20%. It’s because the fact that our current solar panel technology won’t enable the panels to utilize all available wavelengths of sunshine. As an example, in a ray of sunlight, there are several wavelengths. Several of these we’re not able to even see with your human eye alone. The same goes for solar panels.
Sunrgi, an Israeli based solar panel company, has evolved a "concentrated" solar cell that can multiply the wavelengths of light to generate a lot more solar energy with a smaller system. Whilst the company is keeping a tight hang on the technology which allows this advanced solar power, they predict their new panels will produce a kWh to get a mere 7 cents. For the average household, this means a power bill of around $80 monthly! This beats what most Americans pay now- more than $200 a month for electricity. Even better, Sunrgi’s new panels convert an astonishing 37% of sunlight to usable solar panel technology! This really is a lot more than double the amount industry standard. Sunrgi is expecting their first panels out by mid-2009.
The University at Tel Aviv is additionally making huge advancements in solar panel technology. Researchers there have scrapped thinking about using semiconductors in their cells. Instead, they’ve genetically engineered "proteins using photosynthesis for output of electrical energy". Commercial output of such a technologies are a long period down the road, these panels would cost 100x less than conventional silicone and could provide an efficiency around 25%. This will make these panels very popular with poorer countries that want to travel solar but cannot afford conventional silicone panels.
Another promising technological advancement will be the increase in efficiency of thin-film solar panel systems. These thin film panels use 40% less silicone than conventional polycrystalline panels, and so are much less expensive. Unfortunately, next to your skin less efficiency- around 6%. After 2009, some researchers are estimating they shall be capable of producing thin film solar panels with efficiency between 8-10%. This will make then more much like conventional solar panel systems. Plus, more and more people will be able to purchase these less inexpensive panels.
Further developments in solar power technology are in the battery systems you need to use alongside your panels. Annually, new batteries turn out that stay longer and store more energy than previously. This raises the environmental friendliness of solar panel technology to ensure batteries don’t have to be given away or recycled as often.
Solar technology may appear expensive, but the long-term benefits are priceless. Where else are you able to get 25 years of reliable energy costs around $80 monthly? Most certainly not from a utility company. Solar panel technology is reliable, has zero carbon emissions and just will pay for itself within 8-10 many years of purchasing. Money for hard times with the world’s electric supply, residential solar powered energy systems will be the optimum solution to a limitless resource: sunlight.
