- Q: Hello, I am shopping for solar panels for my home and there are so many to choose from. My house uses 40 Kw of power a day. If you had to choose from the output power of a solar panel from below, which one would you choose and why would you choose it? 2 Volts 4 Amps 48Watts2 Volts 8.5 Amps 02Watts6 Volts 7 Amps 2Watts24 Volts 4.2 Amps 00.8Watts24 Volts 8 Amps 95Watts
- the last one has highest wattage. that will bring down the total number of panels you need to meet 40 KW. you probably need 220 panels
- Q: how much do you think it would cost for installation?i heard that solar panels can store electricity and any excess electricity gets sold back to the electric company. how much money can a home owner make from doing this?do you think solar panels are worth it?
- Almost sure that you will discover everything related solar power at www.okorder .
- Q: Can solar panels be used for air conditioning?
- Yes, solar panels can be used for air conditioning. By converting sunlight into electricity, solar panels can power air conditioning units, reducing reliance on the grid and providing a renewable energy solution for cooling purposes. However, the efficiency and capacity of solar panels may vary depending on factors such as the size of the system, available sunlight, and the energy demands of the air conditioning unit.
- Q: Can anyone give me a link to a website that sells really big solar panels? Enough to run a small cafe on entirely solar power.
- I cannot offer a source of info, but... Solar power is great, but not ideal (yet). Currently, one-story buildings that have a rooftop totally made up of solar panels can only get about % of the power needed by that means. Additional panels will be needed.
- Q: What is the principle of solar panels to convert solar energy into electricity?
- When the light is irradiated on the surface of the solar cell, a part of the photon is absorbed by the silicon material; the energy of the photon is transferred to the silicon atom, so that the electrons are moved and the free electrons are formed on both sides of the P-N junction to form a potential difference. When the circuit is used, the current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting the energy of the photon into electrical energy.
- Q: Can solar panels be used in areas with high levels of drought?
- Yes, solar panels can be used in areas with high levels of drought. Solar panels do not require water to generate electricity, as they rely on sunlight to produce energy. Therefore, they can be effectively utilized in regions experiencing drought conditions without any significant impact on their performance or efficiency.
- Q: Got a small project here in a remote location. There is to be a 2 volt deep cycle battery, the equipment to be powered from battery and solar panel to charge battery. The 2 volt battery puts out 55 AH. the max constant power draw from the equipment to be powered is 7.9 watts. Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight?And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge?Thanks to all the input!
- Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight? Maybe theoretically, but you're going to have very little margin for losses and clouds. I'll bet it has very little power when cloudy. 7.9/30 = 0.26. So at 00% efficiency, you'd need it to be charging more than 25% of each 24 hour period. In a summer with long days and a climate with few clouds, you might make it. But I think you're very close to the edge. And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge? For an ideal battery: time = Q V / P time = 55 A h * 2V / 7.9W time = 83 hours So you've got pretty good margin on your battery.
- Q: I'm wondering if the cost of the panels and equipment have come down enough to make them viable in areas like Seattle or Vancuver for example.
- Take okorder /.. You need to keep in mind that as long as you are renting your electric from the public utility you are doing just that and renting. You can resale the solar electric system if you move or if you just want to sale it and get some of your money back if not 20 % extra. Then all the years you used the system was all free electric. So it is already viable as you put it. Anything other then buying a system would not be. Here is a thought. The housing market slumped and if you paid 50K for your home it is now only worth if you can even sale it about 00K. Not worth the money but people are still buying homes even if they are not worth what they are being sold for. And then the cars and trucks people buy will never pay for them selfs but people still buy them and spend extra the more wasteful the car is. So why does solar have to pay for it's self or prove it's self? It has many times over but because you can't drive a solar panel drunk and party out in the bars with it is is not worth the money. I guess the is just being human and a double standard. What about the big up front cost of solar? I remember a 20% up front cost when I bought my home and my car and it is the same 20% or less for a solar loan. Plus the value of solar is going up not down like with homes and a car is not worth but half what you paid for it the minute you drive it off the car lot. I can only see good from solar un like other things we buy.
- Q: Can anyone give me a simple but informative explanation on how solar panels produce electricity/power? Thank you!
- This forum of solar panel is for electric You also get a diffrent type of solar panel this type of panel has a liquid that flows through it and is heated up by the same photovoltaic cells but is ran through the water tank to keep the water warm
- Q: Can solar panels be used in areas with high levels of noise from transportation?
- Yes, solar panels can be used in areas with high levels of noise from transportation. Noise pollution does not affect the functionality of solar panels as they primarily rely on sunlight to generate electricity. However, it's important to ensure that the panels are properly installed and maintained to maximize their efficiency and minimize any potential disruptions caused by noise pollution.
