Q:what are solar panels?
A solar panel is a device that collects and converts solar energy into electricity or heat which can be used by (for example) nearby buildings. Solar photovoltaic panels can be made so that the sun's energy excites the atoms in a silicon layer between two protector panels. Electrons from these excited atoms form an electric current, which can be used by external devices. Solar panels were in use over one hundred years ago for water heating in homes. Solar panels can also be made with a specially shaped mirror that concentrates light onto a tube of oil. The oil then heats up, and travels through a vat of water, instantly boiling it. The steam created turns a turbine for power. The basic element of solar panels is pure silicon. When stripped of impurities, silicon makes an ideal neutral platform for transmission of electrons. In silicon’s natural state, it carries four electrons, but has room for eight. Therefore silicon has room for four more electrons. If a silicon atom comes in contact with another silicon atom, each receives the other atom's four electrons. Eight electrons satisfy the atoms' needs, this creates a strong bond, but there is no positive or negative charge. Silicon atoms combine for years to produce a large piece of pure silicon. This material is used on the plates of solar panels. Combining silicon with other elements that have a positive or negative charge can also create solar panels.
Q:Could solar panels contribute to global warming?
Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!
Q:Solar panels on the roof?
Lots of folks are installing them in my neighborhood in the Mid-Atlantic. I'm going to hold off until I can ask my neighbors how much their electric bill has gone down, after they've had the panels for a year or so. I don't see any reason to rush into it. Also, I'm a little concerned about what happens if a leak develops in your roof during or after installation. Who pays to fix that? That, plus the west side of my house faces the street, and I don't think I want my solar panel array to be greeting guests and visitors...I'm just not that in love with the looks (although the shingle- or tile-like versions of panels that Tesla is advertising would not be bad). So the panel installers would have to be satisfied with an east-facing installation on the rear slope of my roof.
Q:What are solar panels made of?
photograph voltaic panels take power (and in all probability some oil for the plastic) to fabricate, yet that power, and the carbon footprint, is paid for many circumstances over in widespread operation, via the electrical powered energy that the panel generates. The life of the middle photograph voltaic cells is long (there are nonetheless some panels from the 970's that are nonetheless out and dealing), and contemporary panels are oftentimes warranted for 25 years, showing that even the manufacturers have self assurance in thier lifespan. yet whilst it ultimately comes time to eliminate the panels, the aluminum physique is as particularly recycled as the different aluminum, and the tempered, low-iron glass could properly be recycled, too. The plastic substrate is unavoidably solid - it has to stand up to the solar for some years. i do no longer understand what could desire to be achieved with that. The cells themselves are a intense grade of silicon, which has fee on the scrap industry. some panels are no longer made up of silicon - yet lots of the factors could desire to be recycled in a similar fashion. i'm no longer attentive to any intense panels being dumped or discarded at present. they're worth lots, even broken, that some hobbyist or surplus place will purchase them.
Q:Mitsubishi Solar Panels For Home Installation: How Much Do The Panels Cost?
Panels will cost in the range of 300-600 dollars for about 00 watts on average ( enough for one large lightbulb to run a few hours a day). The rest of the system needed will cost $2500-$4000. That is for the equipment. Cost for Installation?? Figure about 0 year life on equipment. It will probably never pay back investment, but will cut power usage. You can reduce power usage much more cost effectively buy simply conserving (Hot water temp. down, CFE bulbs, Better insulation, Better windows, Heat/Air a little colder/hotter, Attic ventilation, Geo Thermal heating/colling system). All of these measures will pay back sooner and save power usage. Solar will never pay back without major subsidies from the taxpayers. Particularly if in an area that has many cloudy days. Check it out. The calculations are basic and the facts are available if you really want them. Don't believe any salesmen or Environmentalists. They don't want you to know the facts.
Q:How may solar panels/wind turbines may be made affordable?
Wind okorder.com/ For the period 87 - 200: Low Risk = bonds = .8% ROI High Risk = stocks = 5.4% ROI For the period 982 - 200: Low Risk = bonds = 5.% ROI High Risk = stocks = 6.% ROI
Q:I have 700watts ups and 2V,65amp battary..i want to add solar panel to just only charge my 2v,65amp batt.?
Are okorder.com/ or hook up several meters and supervise the process regularly. The UPS has no role in the charging—only the discharging.
Q:Solar Panel/Energy help?
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
Q:How much should a 00 watt solar panel cost?
that's going to run a a hundred watt gentle bulb as long because of the fact the sunlight in shining. Or in case you had 8 hours of sunlight shine on the panel stored in a battery you may get 8 hours of light at evening (if the device replace into a hundred% effective which it heavily isn't) you will get approximately 5-6 hours of light from the a hundred watt gentle bulb. In 0 hours of light you will get kwH. So if the capacity business employer can pay you $0.0 for each kwH that's going to take 60,000 hours of light to get returned you $six hundred. approximately 20-30 years.
Q:Can you connect a solar panel to a regular plug, using copper wire?
If you mean powered computer speakers, I think you have a chance. They're low power, and often low voltage. What you want is a parent or your science teacher to give you advice. You will want to find the kind of speaker that has a power adapter that plugs into the wall. The power adapter will put out, say, 6 volts at 200 mA. That's what you want to replace with the solar panel, not wire to the part that plugs into the wall.
