Product Description:

Solar panel conversion efficiency, typically in the 20 percent range, is reduced by dust, grime, pollen, and other particulates that accumulate on the solar panel. "A dirty solar panel can reduce its power capabilities by up to 30 percent in high dust/pollen or desert areas", says Seamus Curran, associate professor of physics at the University of Houston and director of the Institute for NanoEnergy, which specializes in the design, engineering, and assembly of nanostructures.

Q:solar panels, electronics, gear, gadgets for my birthday?
solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said
Q:Which stores can you buy solar panels at?
This one.
Q:How big of a solar panel system would I need to get ?
I think if you have the land have a solar array on your land. Putting on the house could cause it to collapse! 400 kilowatts per week is a huge usage. Turn some stuff off and don't leave the entertainment stuff on standby. Fill empty spaces in your freezers with blocks of polystyrene and be sensible with usage.
Q:Can you connect a solar panel to a regular plug, using copper wire?
Leave the two positive terminals connected together.Disconnect the negative leads from each other. Get two amp diodes from radio shack. Connect each diode in series with each negative lead. there is a band on one end of the diode. Connect each diode so that the end with the band is attached to the negative side of each solar panel. Tie the other ends of the diodes together. This will become the new negative end of your solar panel supply. With the sun shining on the panels , you will now measure the voltage from the plus side of the solar panels to the new negative junction. Connect your load leds in place of the voltmeter and enjoy. Without the diodes , each solar cell thinks the other solar cell is the load. In effect each solar panel is shorting out the other. Some solar panels that you buy already have a diode in their junction box connected for that purpose. You need the diodes to provide the necessary isolation between the two panels, then they can both act in parallel to provide current to the load.
Q:Question about solar panels?
One key piece of information missing is the average number of peak sun hours per day. This will vary by location. It is latitude, regional weather, and site shading must be considered. Another consideration is the loses. The 60 watt solar panel is a DC voltage. The 2300 kWh is for the AC power consumed. There are loses in the inverter to change the electricity from DC to AC. There are also loses for wire resistance, soiling of the panels, wire resistance, etc. To work out an example of the math, I'll use 5 peak sun hours and a total efficiency of 80%. The math can be worked out as a single formula but I'll break it into steps for you. (2300 kwh/month)(month/30.4 days) = 75.65 kWh/day (60 W)(5 psh)(80%) = 240 Wh/day = 0.24 kWh/day/panel # of panels needed = Energy use / Energy generated (75.65 kWh/day) / (0.24 kWh/day/panel) = 36 panels.
Q:What are solar panels made up of?
Solar panels (aka photovoltaic panel) are most often made up of thin wafers of crystalline silicon or cadmium telluride. As photons from the sun enter the photovoltaic cell, electrons are freed from the substrate when are then collected by wires that run throughout the panel. And as we know electrons=electricity!
Q:What do I need to do to run my dehumidifier from solar panels?
Solar Powered Dehumidifier
Q:Solar panels with snow?
In heavy snow areas, snow can build up on panels. If you mount on your roof as most people do, the angle of the panels will help the snow to slide off. Some people encourage the snow to slough off with a very long-handled squeegee or stick. You will see a drastic power reduction when the panels are covered with snow, even if it's just a few of them. However, the panels are made to take snow load, they won't be damaged. Generally, they are also designed to resist hail up to a certain size, if that's an issue where you live. I'd suggest looking in the phone book or on the internet for a local solar installer, and asking them for references close to you. You can then contact the people there and ask how it's working out for them. Also try searching for an answer on the link below. It's a solar discussion forum with very knowledgeable people.
Q:how much does solar panels cost for you home?
Although its costs have been going down a little, solar power is still pretty expensive. To power a home you are looking at at between $8000 to $20,000 dollars (it will eventually pay for itself). There are systems that tie into the existing local power supply so that you have the city's power for back up (note: most power companies will buy electricty from you if you make more than you use). Then, of course, there are stand alone systems that operate without anyother power source (these are best for use in a place where electric lines aren't available or practical).
Q:Solar panels for a netbook?
That strikes me as completely impractical for most circumstances. The power output of your mains adapter is 30W and to do that you are looking at at least five or six square feet of solar panels costing in the region of $600 even from a surplus supplier I know. You could do it cheaper (maybe $50 on panels) but then you would be looking a more primitive panels and need perhaps thirty square feet of solar panels. This is a completely different exercise to creating a solar powered USB charger - the power requirement is a lot higher. Astronomy and space?
