- Q: if you move a solar panel or there was a vibration that caused the panel to move, would that affect it?
- probably not much. If you had it at an optimal angle to the sun and it vibrated out of that position then you could be loosing some efficiency.
- Q: I'm writing a post-apocalyptic story in it the main character finds a warehouse. Eventually he finds out the roof is covered with commercial solar panels. Given it's been over a year since the majority of the world died no manainence was done, do they still work?
- In my experience working with solar panels, I've found that the panels themselves are robust and can last years. How that energy is transferred from the panel to perform work (sorry for the boffinism) is where the complexity emerges, namely due to the fact solar panels produce DC current, and nearly all of our electrical appliances use AC current. In most cases, solar panels will either send energy through a DC/AC inverter directly to be used for appliances, or stored in deep cycle batteries, then converted to AC using an inverter when the user wants to use his/her appliance. Now to answer your question: the solar panels will be fine, and could conceivably be in fine working order with AC current available IF... and I cannot stress this enough (namely through years of field experience dealing with solar powered scientific instrumentation that was working well and then mysteriously not working)... IF rats and other rodents haven't eaten through the wires. This is probably the most likely reason that a set of solar panels wouldn't be working in your given scenario. Hope this helps, and good luck!!
- Q: Do solar panels require cleaning?
- Yes, solar panels do require cleaning to maintain their efficiency. Dust, dirt, bird droppings, and other debris can accumulate on the surface of the panels, blocking sunlight and reducing their ability to generate electricity. Regular cleaning helps ensure optimal performance and maximizes the energy output of solar panels.
- Q: I am working on a project and I have to build a house with solar panels. My teacher asked me how would I get solar energy if it is rainy or cloudy? I looked it up but didn't understand. Please help me!!
- Well you will not be able to produce any new electricity during cloudy or rainy times,your whole system has to be connected to a group of batteries to store the power you do make when the sun is shining.That is the power you will have to run on until the sun shines again.The more batteries you have storing power the longer you can go between recharges.
- Q: if so, would it be possible to make (or remake) an organism that could subsist off of sunlight and external heat like plants?
- Plants and algaes and cyanobacteria already exist. What exactly do you want?
- Q: i was told that by making a solar panel they cause more pollution than they will end up getting rid of. Is that true?
- Absolutely not. This is a myth. The energy payback of a solar panel far outweighs its cost. With current technology (which is vastly improving every year), the payback begins in about -4 years depending on climate. This means that after -4 years, the solar panel has generated the same amount of energy that was used in its entire creation up until the point that it was installed. The panel will then continue to generate power for another 20-25 years at 90-98% capacity if properly maintained. The U.S. Department of Energy has conducted extensive studies on the subject and the results (which i'm quoting) can be viewed on their PV Faq page...
- Q: I have a cabin in the woods and need more light. I do have enough sun but I was wondering how or where do I get a solar panel to lead to a power outlet? In a perfect world I would like to get a solar panel with a connecting wire to an outlet or something so I could power a small TV. I know its hard enough but can I get that pre-made? Or even lastly should I look at wind power consider I would like this to be under $500? Thank you for putting up with this bundle of questions.
- First okorder /
- Q: We have LED at the output of 40 watts and is used for 0 hours giving us 400 Watts-hr of energy consumed.Rechargable batteries needed are 2 V. 400/2 gives us 34 Ampere-hour battery needed. If we want it for 3 days, It would be 34x3=00 Ah. So the battery needed 00 AhNow how do I select the solar panel which can charge this/these batteries? What should be its rating?
- First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
- Q: but is that per day, per hour or minute?How much watts does the average AC unit use?How much does an energy efficient lightbulb use?All in all let's hypothetically say we no longer use the electric company for our energy source, How many of these panels do you estimate it would take to supply our small home?
- The watt is a measure of instantaneous output that can also be used as an hourly measure. volt at amp for hour = watt but also a 00watt bulb requires a 00watt power source, regardless of how long it is on, the 00watts is used as an instantaneous term here. Aircon starts at about 000watts and the new energy efficient bulbs are about 7-5 watts. If you have an electric cooker, that might use 3000 watts, your computer about 500 (very variabke these days though, many are now much lower than this) Your biggest concern would be storage, solar only works when the sun shines so you need a bank of batteries to charge during the day and provide power on demand, they require proper managenemt to ensure ther are charged properly and in turn, an inverter will be required to produce the AC power your appliances will need. It all represents a huge investment with a long payback time and you would still probably need to top-up with a generator during winter, or become ahmish.
- Q: I can't figure out how to charge a Ni Cd (BD 8V Firestorm) battery directly with a solar panel so I've come up with an alternative which might or might not work. I thought I would connect an inverter (I found a nice 400W for $30) to my trucks battery and plug the BD Firestorm battery charger into the inverter. Then I was thinking I could use a 5W solar panel to trickle charge the truck battery and keep it connected after the Ni Cd is charged to ensure the truck battery is topped off. The truck would not be running during this process. Will this solution work? Is there a better solution?
- Two of those solar panels connected in series will easily charge a 8V battery. I would not even be concerned about over voltage the solar cells will have plenty of internal resistance.
