- Q: Can solar panels be used in space?
- Yes, solar panels can be used in space. In fact, they are commonly used to power satellites and spacecraft as they can efficiently convert sunlight into electricity even in the absence of an atmosphere.
- Q: I heard the wind turbines, solar panels so far provide America with around 2% of our energy. So since liberals appear to want to replace natural energy with man made products, that cause massive pollution by the way to make- How long will that take 30 years, 00 years? How many Wind Turbines will Airplanes and birds and parachute jumpers smash into, isn't that a problem? How do we rid of natural energy before we have the LIBERAL BACK UP PLAN - WE DON'T REALLY HAVE ? How do they think this is gonna work? Its not logical, we need to come up with more ideas! That Battery idea kinda sucks since Batteries Need natural energy to work.
- There is an abundance of free energy available on this planet. Wave, wind, solar, (underground), and many many others that I can't remember right now. If some of the multi-trillions currently being spent being spent by the US government on defence (and the rest of the planet defending ourselves FROM the US) were re-directed towards exploiting sustainable, long-term energy supplies, then much work would be generated and the cost of energy would drop significantly - in the long run. So, why are we not utilizing these sources of energy? Unbelievably short-sighted right-wing political ideology, that's why! One thing almost never reported about nuclear power, is that there isn't much nuclear power fuel available on this planet. I think I can quite honestly state that when the time comes when we are forced to move from non-renewable to renewable energy production, it will probably be far too late with far too much damage done and the environment will collapse and become incapable of supporting oxygen breathing life-forms. I concluded many years ago that capitalism will probably end all life on this planet one day. Capitalism IS right-wing politics! Do you now see where the problem is coming from?
- Q: I remember hearing somewhere that solar panels may attract light rays away from plants thus having a potentially negative effect on the plants. I can't remember where I heard it but I'm curious if there is any truth to it.
- not so. the sun shines on the earth and everything on it. the solar panels are on the earth like on top of your house maybe.if they were not sitting on top of your house , the sun would still be shining on your roof. it makes no sense to say they were drawing light away from other plainest when the sun would still shine on the place where they are if they were not there.
- Q: when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?
- That portion of the sun's light to which it responds, of which it converts 20% to electricity.
- Q: What is the impact of hailstorms on solar panels?
- Hailstorms can potentially cause damage to solar panels, particularly if the hailstones are large and the panels are not adequately protected. The impact can range from minor scratches and dents, which may not affect the overall performance of the panels, to more severe damage that can impair their functionality. However, advancements in technology and the use of durable materials have made modern solar panels more resistant to hail damage. Proper installation and maintenance, including the use of protective measures like tempered glass or hail guards, can further minimize the impact of hailstorms on solar panels.
- Q: If you need 9400 watts, 75 amps@ 240V, how many solar PV panels do you need?
- 75 amps @ 240 volts equals 8 kW not 9.4 kW, so first you have to make up your mind how much you want. Then you have to decide what size of solar panel you want. If it helps, the 6 units on our roof, each approximately m square, are rated for 4 kW in bright sunshine.
- Q: How do solar panels affect the resale value of a property?
- Solar panels can have a positive impact on the resale value of a property. Studies have shown that homes with solar panels tend to sell faster and at higher prices compared to homes without them. This is mainly because solar panels can lower energy costs for homeowners, increase energy efficiency, and contribute to a more sustainable lifestyle, all of which are highly valued by potential buyers.
- Q: Can solar panels be installed in rural areas?
- Yes, solar panels can be installed in rural areas. In fact, rural areas are often ideal for solar panel installations due to the availability of open spaces and ample sunlight. Installing solar panels in rural areas can provide clean and renewable energy to these communities, reducing their dependence on traditional energy sources and improving energy access.
- Q: Hi, wanting to set up the most basic solar panel system for a cabin in the woods that has enough power to recharge four 2V car batteries during the daytime (i am assuming; we want to run a mini fridge maybe a stove and a few lights at night off the batteries and be able to run it all just off solar during the day) It also needs to be able to power some simple tools during the day... Experience would be absolutely amazing since alot of the info on solar paneling is either really dumbed down, or ridiculously confusing.As of right now I am looking at a 3 panel (45watt in all) solar kit that needs a 300w inverter.... is this sufficient for my power needs? I am just a little perplexed, thanks so much!
- ever looked at the light from a 45 watt bulb? it's true that in a cabin, if you're in the right place, you can read from it. however, assuming that you get 6 hours of sun, you can run your light for 4-5 hours. and nothing else. if you're hoping to run a stove, you're going to need several hundred watts. not sure what tools you're thinking of, but i don't know of many that run on 2v DC. (not sure that i know of a stove that runs on 2v DC either, but you can look that up.) for tools, you might want to consider a gas powered compressor and air tools. that'll give you the strength that you need. yes, i know that's not what you were thinking, but pretty obviously you're going to need to do a bit more thinking. even a minifrig is going to use considerably more than 45 watts. and that would be 24 hours a day. remember, a minifrig has considerably less insulation. you can't save much and per pound, it takes more juice.
- Q: Can solar panels be used to power a space station?
- Yes, solar panels can be used to power a space station. Solar panels convert sunlight directly into electricity, and in space, where there is no atmosphere to scatter or absorb sunlight, they can generate a significant amount of power. Several space stations, including the International Space Station (ISS), rely on solar panels to generate electricity for various systems and experiments.
