At this time, the best solar power systems can reach an optimum efficiency of about 15-20%. The reason is , the fact our current solar panel technology won’t permit the panels to utilize all available wavelengths regarding. By way of example, within a ray of sunlight, there are various wavelengths. Several of these we simply cannot even see with our human eye alone. The same goes for solar power systems.
Sunrgi, an Israeli based screen company, is rolling out a "concentrated" solar cell that will multiply the wavelengths of sunshine to make a lot more solar energy on the smaller system. Whilst the clients are keeping a strong hold on tight the technology that allows this advanced solar technology, they predict their new panels will make a kWh for a mere 7 cents. To the average household, this equals an electric bill of about $80 each month! This beats what most Americans pay now- well over $200 a month for electricity. Better yet, Sunrgi’s new panels convert a whopping 37% of sunlight to usable solar power! That 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 cell technology. Researchers there have scrapped the idea of using semiconductors within their solar cells. Instead, they’ve got genetically engineered "proteins using photosynthesis for production of electrical energy". Commercial output of this kind of technology is a long period down the road, however these panels would cost 100x below conventional silicone and might produce an efficiency around 25%. As a result these panels very attractive to poorer countries that are looking for to look solar but do not want conventional silicone panels.
Another promising technological advancement may be the boost in efficiency of thin-film solar power systems. These thin film panels use 40% less silicone than conventional polycrystalline panels, and therefore are much less expensive. Unfortunately, next to your skin less efficiency- around 6%. By the end of 2009, some researchers are estimating they will be able to produce thin film solar panels with efficiency between 8-10%. This makes then more comparable to conventional solar panel systems. Plus, lots more people should be able to get yourself a dvd less inexpensive panels.
Further developments in solar power technology come in battery systems you need to use alongside your panels. Annually, new batteries emerge that keep going longer and store more energy than any other time. This boosts the environmental friendliness of solar panel technology to ensure that batteries must not be thrown out or recycled normally.
Solar power might appear expensive, however the long-term benefits are priceless. Where else could you get Two-and-a-half decades of reliable energy costs around $80 a month? Definitely not from your utility company. Solar panel technology is reliable, has zero carbon emissions and just covers itself within 8-10 years of purchasing. In the future of the world’s electric supply, residential solar energy systems may be the solution to some limitless resource: sunlight.
