how are solar panels energy efficient
How much energy on this particular solar panel produce?
It http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100660082 lists "123 W maximum output, 7.16 amps, but is that per day, per hour or minute? How much does the use Watt AC half unit? How much is a use of energy efficient light bulb? All in all scenarios we say that the company no longer uses electric power source, How many of these groups do you estimate would be needed to supply our tiny house?
Some great answers than 123 watts per hour is alive in an area that has 5.5 hours of sunshine average solar radiation data that would give me a base of 676 watts produced per day for a panel. This STC is 123 watts likely or standard test conditions is far from standard, ideal 70 degrees Fahrenheit with a flash 1000 is PTC or conditions of the physical evidence does not always labels and not always accurate due to varying conditions. Heat is a huge factor in the production of PV. The panels must be derated by the current rating after correction reason or line loss correction PTC temperature correction these corrections represent investor loss around 15% in standard panels of 676 watts per Our day has been reduced to 574 watts per day per panel lets start with the bulb. a standard 60-watt bulb uses 60 watts per hour. With a panel we have chosen, there would be 5 hours and 45 minutes of illumination If switching to a 15W CFL and have average 38 hours lighting one Central Air big difference if used around 2000 to 2500 watts for hour.This rule is not hard and fast that the units can vary, as conditions of use allows 2000 times per hour 8 hours of use is 16,000 watts you need 28 panels by the CA. Probably another 28 for the rest of the house Of course, this panel must be true to 15 degrees south, mounted with a year's worth of electricity bills and a site visit could come spend closer, but let's say you need 60 of those panels of this system provide 973kHw a month at my place of hours of sunshine per day 5.5 This would be a network system as discounts tied most states require a network linked system to qualify for the discounts
