The Growing Technology of Solar Power
At this time, the top solar power systems can reach a peak efficiency of approximately 15-20%. The reason is , the reality that our current solar technology will not permit the panels to use all available wavelengths of sunshine. For example, within a ray of sunlight, there are several wavelengths. Many of these we simply cannot even see with our naked eye. The same goes for solar power systems.
Sunrgi, an Israeli based cell company, is rolling out a "concentrated" solar cell that could multiply the wavelengths of sunshine to generate considerably more solar power on a smaller system. Even though the firm is keeping a good hang on we've got the technology that permits this advanced solar technology, they predict their new panels will develop a kWh for a mere 7 cents. For that average household, this equals an electrical bill of about $80 per month! This beats what most Americans pay now- above $200 monthly for electricity. Also, Sunrgi's new panels convert a whopping 37% of sunlight to usable solar power! This really is more than double industry standard. Sunrgi is expecting their first panels out by mid-2009.
The University at Tel Aviv can also be making huge advancements in solar panel technology. Researchers there've scrapped thinking about using semiconductors of their solar panels. Instead, they have got genetically engineered "proteins using photosynthesis for creation of electrical energy". Commercial production of such a technology is a few years in the future, but these panels would cost 100x lower than conventional silicone and may produce an efficiency around 25%. This will make these panels very irresistible to poorer countries that want to travel solar but do not want conventional silicone panels.
Another promising technological advancement will be the surge in efficiency of thin-film solar power systems. These thin film panels use 40% less silicone than conventional polycrystalline panels, and so are much less expensive. Unfortunately, there is also less efficiency- around 6%. After 2009, some researchers are estimating they shall be capable of producing thin film solar cells with efficiency between 8-10%. This makes then more much like conventional solar power systems. Plus, more and more people should be able to purchase a copy less inexpensive panels.
Further developments in solar panel technology will be in the battery systems you should use alongside your panels. Annually, new batteries come out that keep going longer and store more energy than in the past. This increases the environmental friendliness of solar panel technology so that batteries doesn't have to be trashed or recycled normally.
Solar energy might seem expensive, however the long-term benefits are priceless. Where else could you get Twenty five years of reliable energy costs around $80 30 days? Certainly not from a utility company. Solar energy is reliable, has zero carbon emissions and easily pays for itself within 8-10 many years of purchasing. For the future of the world's electric supply, residential solar powered energy systems would be the best answer to some limitless resource: sunshine.
