- Every day we are being misled or getting ripped off by some unscrupulous sales man trying to make his commission, bonus or quota. Being caught in the “Close” is about the salesman using the technique effectively. The Solar industry is continuously mis-representing efficiency to you, the customer about to spend 5, 10, 20, 40 thousand for a system. How? By telling you their efficiency is the best. But what you don’t know is it may be for a short 1-2 hour period or even minutes at the PEAK efficiency. The rest of the time it’s not so good. So your overall efficiency levelized over 24 hours is, well pretty dismal.
That’s right they don’t want “off peak” to make a levelized playing field for EFFICIENCY over a 24 hour period. Makes sense to some degree. The sun doesn’t shine at night, unless you count reflecting moon beams. It’s awfully dark on a cloudy night, not to mention some hellatious thunderstorms have turned day into night, it’s that dark. And overcast days don’t help with enriching that tan you managed to acquire baking in the sun. But I do remember getting burnt on cloudy days at the beach. Must have been my imagination, a wind burn, that is what it was, a wind burn. Or was it something else? I remember some one mentioning UV. I can’t see it or feel it like the sun rays, so that couldn’t be it, or could it?
We are entering a new phase, a paradigm shift for the energy industry. Customizing your longitude and latitude characteristics to the generation facility for your power. UV, IR, and VL all come into play some time during the day and night. Visible light (VL) is pretty obvious as well as the Ultra Violet (UV) , that ‘s why we wear our sunglasses to protect our eyes from UV, not because we look good in them. And then the IR, what is infrared (IR)? It’s complicated to explain as you will see from the Wikipedia definition: “Infrared Technology is based upon (IR) light that has electromagnetic radiation with a wavelength longer than that of visible light, measured from the nominal edge of visible red light at 0.7 micrometres, and extending conventionally to 300 micrometres. These wavelengths correspond to a frequency range of approximately 430 to 1 THz, and include most of the thermal radiation emitted by objects near room temperature. Microscopically, IR light is typically emitted or absorbed by molecules when they change their rotational-vibrational movements. “ Got that? Well to put it more in the terms of how it is used in solar applications they go on to say:
Sunlight at zenith (climax or high point) provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 527 watts is infrared radiation, 445 watts is visible light, and 32 watts is ultraviolet radiation.”. The wafer type solar cells available today can only process visible light. That leaves out over half of the energy available from IR and the remainder in the UV. 56% of the available energy to be converted to electricity is LOST using today’s solar cells. Tomorrow using the Solterra Renewable Technology flexible solar cell you will be able to capture that lost energy in the IR and UV region. And what is really exciting about this new Nanotechnology with Tetrapod Quantum Dots is it’s absorption capability 24 hours a day! Like enhanced night vision goggles the IR at night is enough to continue generation of power around the clock. So when someone tries to sell you on their solar cell being the most efficient, ask them to tell you the 24 hr energy absorption and overall efficiency rating for the panel. That will stop them dead in their tracks and ask them what is their LCOE?
LCOE is the Levelized Cost of Electricity over the life of the power generating facility. Starts from construction costs and runs to disposal, a “cradle to grave” cost in which to compare overall generating cost. The lower the LCOE the better you are. Now you have something tangible to compare.
