Right now, the top solar panels can reach an optimum efficiency of around 15-20%. Simply because the fact our current solar panel technology doesn’t enable the panels to use all available wavelengths regarding. By way of example, within a ray of sunlight, there are many different wavelengths. Several of these we simply cannot even see with the human eye alone. The same goes for solar power systems.
Sunrgi, an Israeli based screen company, is promoting a "concentrated" solar panel that may multiply the wavelengths associated with to generate far more solar power on a smaller system. Even though the company is keeping a tight wait we’ve got the technology that enables this advanced solar energy, they predict their new panels will develop a kWh for a mere 7 cents. For your average household, this compatible an electrical bill of about $80 each month! This beats what most Americans pay now- more than $200 monthly for electricity. Better yet, Sunrgi’s new panels convert a stunning 37% of sunlight to usable solar power! This 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 can be making huge advancements in cell technology. Researchers there’ve scrapped the concept of using semiconductors within their solar panels. Instead, they’ve genetically engineered "proteins using photosynthesis for production of electrical energy". Commercial creation of this kind of technologies are many years later on, however, these panels would cost 100x lower than conventional silicone and could produce an efficiency around 25%. This may cause these panels very attractive to poorer countries that are looking to look solar but do not want conventional silicone panels.
Another promising technological advancement is the boost in efficiency of thin-film solar panels. These thin film panels use 40% less silicone than conventional polycrystalline panels, and therefore are a lot less expensive. Unfortunately, next to your skin less efficiency- around 6%. By the end of 2009, some researchers are estimating they shall be able to produce thin film solar cells with efficiency between 8-10%. This may cause then more just like conventional solar power systems. Plus, more people are able to buy these less inexpensive panels.
Further developments in cell technology come in it systems you may use alongside your panels. Yearly, new batteries come out that last longer and store more energy than any other time. This increases the environmental friendliness of solar technology to ensure that batteries needn’t be trashed or recycled as frequently.
Solar power may appear expensive, but the long-term benefits are priceless. Where else can you get 25 years or so of reliable energy costs around $80 per month? Certainly not out of your utility company. Solar power is reliable, has zero carbon emissions and just covers itself within 8-10 numerous years of purchasing. For the future from the world’s electric supply, residential solar energy systems could be the optimum solution into a limitless resource: sunlight.
