Q:question about Solar Panels?
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
Q:Blocking diode for solar panel?
At least a 2 amp diode. rated above the 2 volts that are commonly found on the market. A blocking diode must be able to stop a higher current and voltage than the panel maximum. A diode will work on any voltage and current lower than it rating.
Q:harbor freight solar panels ?
Put my panel on roof of my motor home, regulator in belly rack with house batterys. Have had no problems in a year or so and they keep the house batterys charged
Q:What home appliance can be powered by a solar panel?
Solar panels could supply an air conditioning unit but it would be SUPER expensive to do. Air conditioners are power hogs.
Q:can solar panels be refurbished?
Solar water heating panels can be salvaged for the copper and aluminum in them. Unless there's catastrophic damage, solar electric panels only weaken with time. Given that serious panels have a life of over 25 years, it's debatable whether anyone would want them after they've served their useful life, any more than someone would want a 386 computer from 985 running at 6 MHz. The glass and metal could be recycled, but the acutal solar cells I think would be thrown away. Contemporary panels are made ROHS compliant with zero lead, so are not especially toxic.
Q:Life expectancy of LEDs and Solar panels...?
LED's 6 years or longer
Q:Why do glass covers improve the efficiency of solar panels?
Clear glass will allow most of the electromagnetic energy of sunlight into the air-tight volume of the solar panel. The light strikes the black coated metal tubes and the black coated backing, and is absorbed as heat. Part of this heat will radiate as infrared radiation, and much of this will leave through the glass. But a great deal of it will initially remain in the metal as heat. This heat will be partially transferred to the surrounding air, but because the glass stops the mixing of this air with the rest of the atmosphere, this heat will stay mostly contained within the solar panel. If the glass were not there, there would be a huge loss of heat into the surrounding air.
Q:how do buildings circulate energy?
The answer depends upon the type of solar energy captured . Photovoltaic Solar Panels convert the energy into electricity. This electricity is ran throughout the building via wires. Thermal Solar Panels typically capture the energy in the form of heat. The hot water is circulated through the building in water pipes.
Q:solar panels and calculations?
The okorder.com The reference section has all the formulas you are looking for and there is a list of dealers by state, plus various state rebate information. Yes, you can hook up different panels to the same system. There are special controllers that regulate the voltage. I'm more of a hands on nuts and bolts guy so I can't help you with the formulas and engineering explanations. Another great place to get information is Home Power Magazine. You can get the issues online or in print. Thanks for going solar!
Q:Reflectors or mirrors around the solar panels.......?
In the 70's when silicon was really expensive, they played with using fresnel lenses to focus the sunlight on small solar cells but these panels had to be on heliostats and aimed directly at the Sun. These days, with nano-technology, there's a renewed interest in the concept but the fundamental weakness is that there are diminishing returns, at some point, it's just less expensive to have more solar cells.
