- Q: solar panel capacity, how do it work
- Solar panels are made of solar cells.Solar cells are mainly made of a semiconductor called silicon,when sunshine on it,solar energy is converted into electrical energy by photovoltaic.The energy knocks electrons loose, allowing them to flow freely.This flow of electrons is a current, this current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.
- Q: Can solar panels be installed in areas with high seismic activity?
- Yes, solar panels can be installed in areas with high seismic activity. However, extra precautions need to be taken during the installation process to ensure their stability and resistance to earthquakes. Specialized mounting systems, such as those with adjustable foundation designs or seismic restraints, can be utilized to secure the panels in such areas. Additionally, it is crucial to comply with local building codes and regulations to ensure the panels are installed safely and can withstand seismic events.
- Q: Can solar panels be used in deserts?
- Yes, solar panels can be used in deserts. In fact, deserts are ideal locations for solar panel installations due to the high levels of sunlight and low cloud cover. The abundance of sunlight in deserts makes them an excellent environment for generating solar energy efficiently.
- Q: Can solar panels be installed on mining or extraction sites?
- Yes, solar panels can be installed on mining or extraction sites. In fact, installing solar panels on such sites can provide numerous benefits. They can help reduce the reliance on fossil fuels, lower energy costs, and decrease greenhouse gas emissions associated with the mining or extraction operations. Additionally, solar panels can provide a sustainable and renewable energy source, contributing to the overall environmental sustainability of these sites.
- Q: And I'm tring to decide if I should buy it. Let's say my house would need Megawatt per hour. That's 000 megawatts per hour. This solar panel produces 36 watts. I don't know how if that means per hour or what???
- There is no such thing as a megawatt per hour. Watts aren't a unit of energy, watts are a unit of power. Power is the rate at which energy is converted. Power is to energy as speed is to distance. Watt-hours or the famous kiloWatt-hour are units of energy. Also the Joule is the more scientific unit of energy.
- Q: i have a 2v 2a solar panel that i want to use to charge a 2v battery .Have found out that i need a charge controller so i don't over charge the battery.I have found a cheep one its 2v but 7a will it still work ?All-so im planing on running a 2v water pump off the battery with a timer,its for watering my garden.Will the timer have to be 2v as well ?any help on this would be greatly appreciated thanks .
- The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .
- Q: Has anyone actually used those kits online like energy4green or earth4energy to build their own solar panels or windmills? I'm so tempted but with my budget can't afford to waste any money. They have a 60 day money back policy but that doesn't include the money used to buy the supplies to try and build the things. My electric bill is almost $300 a month due to my stay at home disabled veteran husband who went from Utah snow to Florida sun and he has to have the AC on really cold. If anyone has actually built one can you tell me of your experience and if it actually is worth the money? I do lots of D.I.Y. projects but am a novice with electric besides installing a ceiling fan and changing out a light switch.
- What I've heard, is that for those sites implying that you can power your house and save money with homemade solar panels, is that if you try to get your money back, there is no response. Maybe if you used a real credit card, you could dispute the charges through your credit card company. Actually, I wouldn't be worried about buying materials and it not working - the more likely scenario is that you would get their instructions, and realize that they're practically worthless. In Florida, you have a chance to save money on your electric long-term, but it will be by investing maybe $0-20k, and then getting that back after 0 or more years. I'd suggest you contact a local solar installer and get a bid, even if it's only to scope out how much it would cost up front. Then you can shop around and see if you could save by installing it yourself. It's a serious project, not to be taken lightly. It took me about 3 months to put it up. It's possible that you will not save money by self-installing, as professionals may get better prices on the panels. The Florida state rebate is subject to availability of funds, and typically, I've heard people wait a long time to get it. The Federal rebate is a credit to your taxes, so you get it the next year.
- Q: Was looking at 0w solar panel kit. Does this mean, all I can use is something like a 0W CFL light bulb and nothing else?
- 0w Solar Panel Kit
- Q: Can solar panels be used for charging electric vehicles?
- Yes, solar panels can be used for charging electric vehicles. Solar panels convert sunlight into usable electricity, which can then be used to charge the battery of an electric vehicle. This enables vehicles to be charged with clean, renewable energy, reducing both emissions and dependence on fossil fuels.
- Q: How are solar panels made?
- Solar panels are made using a complex manufacturing process that involves several key steps. First, high-quality silicon ingots are sliced into ultra-thin wafers. These wafers are then treated with various chemicals to enhance their electrical properties. Next, metal contacts are added to the front and back of the wafers, allowing for the flow of electricity. The wafers are then assembled into a module, encapsulated in a protective layer, and sealed with a glass cover. Finally, the completed solar panels undergo rigorous testing to ensure their efficiency and durability before being ready for installation.
