I say yes, I had a system put in a few months ago. I paid $6K and my utility paid $0K. I should break even in about 6 years. The system is guaranteed for 25 years, so I will have at least 9 years of free energy. I went from a bill of around $200 per month to under $20 in the summer. I will pay a little more in the winter months because less daylight, but I don't use as much energy in the winter. Each year electricity goes up an average of 5%, so while my neighbors have a larger bill each month, I'll be staying under $50 for a long time. Even without the rebate I would have a break even time of about 0 years, still 5 years of free energy.s
Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.s
If you mean a LASER pointer, then the answer is YES. However, the light is concentrated on a very tiny spot, so the panel will NOT generate much. Laser pointers are rated in milliwatts. A typical red laser pointer is rated at maybe 3 milliwatts. So, that is all that will be transferred at MOST. You don't get something for nothing, so the panel MAY put out 3 milliwatts from the laser pointer, but probably less since the solar panel is not 00% efficient. Solar electrical panels rely on sunlight over a large area measured in terms of many square FEET of area. As for driving lamps, the lamps do not care where the power comes from, only that the voltage and current are correct. Most bulbs will work equally well on AC or DC. Solar panels are used to charge batteries, and the batteries are used with an inverter to supply 0 VAC to things like appliances. What you CAN do is use a laser pointer to turn off a photoelectrically controlled light, such as a streetlight, maybe. Many streetlights have a photocell on top which looks at the sky and turns on the light when it is near dark until shortly after dawn. If you can shine a laser on the dome of the photocell, it MAY be bright enough to fool the photocell into thinking it is daylight and turn the streetlight off for a while...s
There are many, upon many variations of equipment needed for a complete solar home. I would call several contractors in your area that deals with it and get estimates. You have to look at what your wattage diet is at your home. How many watts are you using for your AC and heat. Which can vary by age, efficiency, insulation of home, etc. Look at your electric bill for a normal summer month and a normal winter month, then estimate your heating and cooling (Sometimes can be as much as 70% of the bill). You will see on your bill your toal kilowatt hours. ( Kilowat = 000 Watts) Solar systems can start as low as $2.00/watt, but can rapidly approach $20.00/watt depending on the difficulty of application etc.... Here is the great thing, in many areas of the country there may be rebates from the county or state. And what you don't use can be fed back into the grid, and you get paid for it. But as always - Call a quailified contractor and get the right system for your home.s
Yeah lead acid is the desirable yet once you've a higher image voltaic setup like 200watts or extra you extremely want a cost controller in addition they favor to be vented because even as they're charged the produce hydrogen that once concentrated burns and is no longer good to respire in. the worst section about lithium ion is they imeadiatly commence to decompose once they're used so that they in straight forward words very last 2-4 years the position lead acid can very last over 2 years if good maintained.s
