photovoltaics uni-solar® solar shingles triple overlap works and looks like a conventional roofing shingle but also produces clean non-polluting electrical power mount on regular roof decking and felt uni-solar pv shingle 5 active underlay with common roofing nails they install coll exposure with consecutive overlapping layers each shingle fits over the inactive top 7 of the previous one as sunshine warms them up a special adhesive bonds the shingles together forming a weather resistant roof covering the triple overlap bottom of each shingle has 12 electrical wires that connect below the roof deck made from uni-solar pv uni-solar triple shingle 5 active junction amorphous coll exposure silicon cells they meet shingle wind load tests and include bypass diodes 10 year warranty to

more research and testing since the earliest days of civilization people used solar energy even cavepeople chose their dwellings to best use the sun ancient greeks persians and chinese used solar architecture and designed entire cities with solar principles romans in the second century b.c used the sun to heat their public baths hero of alexandria made a solar pump in the first century a.d leonardo da vinci made plans for industrial applications of solar power in the early 1500 s european scientists made solar ovens in the 1700 s the photovoltaic effect was discovered way back in 1839 in the 1860 s and 70 s a french inventor made the first solar engine a solar pump that moved over 500 gallons of water an hour and a device that used the sun to make ice in 1904 a solar water pump in california steadily did 1,500 gpm 1904 also saw the first commercial solar power plants in 1913 egypt had a 55 hp solar engine pumping 6000 gpm world war i intervened however stopping development in 1900 over 1600 homes in california used solar water heaters one company in the 1920 s was selling over 1000/year by 1941 more than half the population of miami florida used solar heated water the world war ii governmental freeze on copper however stalled the us solar water industry and rapidly falling gas prices after the war almost completely killed it inexpensive coal and gas prices as well as utility promotions from 1945 to 1968 caused a 500 increase in electricity generation and decreasing interest in solar unfortunately this trend continued with little regard for the environmental consequences until recognizing the dangers and difficulties with waste disposal an infatuation with the possibilities of cheap nuclear power further diverted interest and solar research development today we may need solar power more than at any other time in history as the developing world rushes towards the progress achieved in the west the negative environmental consequences became more critical if the rest of the world used as much energy and resources as north america we would need two extra planets to provide enough resources today s us pollution levels from power plants one billion tons of carbon dioxide 6 million tons of nitrogen oxides and over 5 million tons of sulfur oxides going into the atmosphere each year solar energy s story stretches beyond human recorded history for a reason in many ways the use of solar power paralleled the success or failure of the civilization for example switching from solar architecture to wood heat was a significant contributing factor in the fall of the roman empire throughout history civilizations have nurtured solar energy to their advantage or ignored it to their peril though the question may be the same given modern population technology and lifestyle the consequences of our decision become increasingly critical uni-solar laminates 60 watt easy install low shipping charges best price per watt peel-and-stick
