- Q: Single crystal solar panels and polycrystalline solar panels
- monocrystalline silicon market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.
- Q: i am looking at installing some solar panels and a wind turbine for electricity.has anybody got one of these and how much do they save you?thanks
- If you are planning on purchasing a solar or wind system installed etc. I believe it will take considerable time to pay off. If however, you are even remotely handy, building a 3kw wind generator is well within the realm of possibility. I have a smaller windmill that I built myself using some ingenuity and some parts bought on OKorder. That windmill and 4 2 v deep cycle batteries run myu 9 share well 24 hours a day. I spent about $250 to build the windmill, tower, and buy used batteries, and have saved an average of $60/month for months now. This really isn't rocket science either, I'm a freakin' cook =) for more on the subject of diy wind and solar projects see the resource below.
- Q: what is needed beside the panels and do you need an electrician to hook it up
- A decent installation needs a solar engineer to make sure the panels are aligned to take advantage of all the solar it can get. that or You need to hit the books on solar radiation. online I would try different programs to get the feel. we get less solar radiating in the winter then in the summer. this needs to correctly compensated.
- Q: hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.
- wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
- Q: I want to build solar panels for my house.Dose anyone try okorder is this really work?
- Build okorder
- Q: What would it take to make a heater for a small solar panel. I am looking into making a heater for a livestock tank to keep ice melted. I know that heaters take alot of energy to run, but my theory is that if heated mirrors on a car can melt ice with low voltage and im sure not extreme heat (40-60 degrees) then making a heater with just high enough temperature to keep from icing over and melting ice is possible. Where do I start? I would like to use an inexpensive solar panel that will generate enough heat to keep ice from forming and melt it at the beginning of the day. How can you make such a heater and apply Ohms law so that it will function correctly, what Wattage will the pannel need to produce to generate enough heat for the heater. The device will only have to be large enough to melt a spot large enough for an animal to drink.
- Absolutely. But I see your point about the Ohms law. I think you'd need technical schematics to get the raw details.
- Q: Can solar panels be used to power a restaurant?
- Yes, solar panels can be used to power a restaurant. By installing solar panels on the rooftop or in a nearby area, the restaurant can generate clean and renewable energy to meet its electricity needs. These panels convert sunlight into electricity, which can power various appliances, lighting, and other electrical systems within the restaurant. Additionally, solar panels can help reduce the restaurant's reliance on the traditional power grid, leading to potential cost savings and environmental benefits.
- Q: Can solar panels be installed in areas prone to hurricanes or tornadoes?
- Yes, solar panels can be installed in areas prone to hurricanes or tornadoes. However, it is important to design and install the solar panel system with the specific weather conditions in mind. This includes using appropriate mounting systems, ensuring proper anchoring and reinforcement of the panels, and using high-quality materials that can withstand strong winds. Additionally, regular maintenance and inspections should be conducted to ensure the panels remain in optimal condition.
- Q: What is the most efficient solar panel, how many would we need to power the United States, and how much land would it take?
- Annual power consumption in the US is approximately .2*0^5 Watt-hours. The average solar panel can generate 80W continuously. We can break up the calculation into parts: .2*0^5 Watt-hours per year 925 hours per year .3*0^ continuous watts 80W per panel 64383566 panels 000 sq. inches average solar panel area 650 million square miles (!!!) To give you a better idea, the total surfacre area of the United States of America is 3 million square miles. The surface of the earth is 96 million square miles. Not even 3 planets full of solar panels would be enough. Maybe it is easier for people to start using electricity more responsibly?
- Q: Can you connect a solar panel to speakers that use a wall outlet plug, by cutting the plug off and connect copper wire between the solar panel and cord?Confusing i know. I'm trying to connect a solar panel to speakers for a science project.
- 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.
