- Q: Why might energy from the solar panels sometimes be near zero even in the summer?
- Hey Cosmic, forget about Wayfare and Jenny here, but I have to say your question is a bit vague. When you say the panels produce near zero, how near? Are you using a watt meter, ammeter, or some other sort of metering device. Solar electric, or photovoltiac panels are made almost entirely of silicone wafers. Same as computer chips, when they get hot, the resist the flow of electrons. This is why most panel manufacturers advise installers to upgauge wiring if the temperature falls below 40 degrees F (5C) regularly. Below 0 C, you have to upgauge 2 wire sizes. A good quality panel will put out 50% of its rated power in very cold climates, so it stands to reason that they will put out substantially less in hot weather. Many people think places like the SW United States is great for solar because it's always sunny. In Las Vegas for example, they have 27 sunny days a month, and in August, the temperature frequently reaches 50 degrees C (20F) so people with photovoltiac panels are not even getting half their rated power on a good day. I'm not sure this is what you are asking about. Our home has been powered by the wind and sun for 2 years now. In the summer in the upper midwest, the days are warmer of course, but also much longer than in the winter. So our batteries will frequently fill up by 2:00pm, and the charge controller will taper off the solar charging the rest of the day to minimize overcharging. If you were to check the meters at 3pm, you might notice only 3 or 4 amps coming in when the array is rated at 42. This is normal for us in July and August. These are some reason why a solar array produces near zero in the summertime. Take care Cosmic, Rudydoo
- Q: . The 2v battery will only be turning a small 2v motor that will be turning very slowly yet possibly or a long time. 2. -2 hours max per day it will be running3. I want it to be fully sufficient on solar power once the energy in the battery runs out. What specifications for my panel do you think I will need. However, i have limited space so the smaller the better as long as it can do the jobP.S: I don't know much about electricity and solar power so simple answers please :)
- Are you concerned about your higher energy bills? What about the atmosphere, are you worried about its resources that are nonrenewable? Solar energy and how to make solar panel are the solutions for you. Let us talk about the charges of pv strength and how practical it is for YOUR budget. The first thing you should know is that the size of your house has nothing to do with the cost on how to make solar panel. So for those people fortunate sufficient to are living in a gigantic property, pv panels are not here to overwhelm you with charges. What you do need to consider into consideration are items like how much sun you get a day, in which you stay, and how very much power you use a day. After you can appear to individuals conclusions, we can commence the math. Permit us do an instance together to figure out a ballpark expense for pv panels. Take a peak at your power bill as it is now and locate how numerous KWH you used, We will say that variety you found was 800 KWH. Now we are going to divide 800 by 30 and we get a whopping 26. 7. Don’t forget that quantity. It is how very much estimated KWH you use a evening. If you locate that you are exposed to six hours of sunlight a morning you would then consider the 26. 7 and divide it by 6. You reply should be four. 45 (or 4,450 watts). If you multiply that reply times . 5 you have successfully observed out how a lot of photo voltaic panel watts you need. The installation costs then are associated to the quantity you found above. Each and every watt usually costs $7-$9. All your installation fees need to be integrated with that estimated ending price. Now that you know how very much your method will charge, you will be relieved to know that it actually pays for itself inside six many years. There are also tax exemptions for people that select to use pv vitality. It is an investment that is really worth anyone’s time and funds Hope It's Help.
- Q: where to find used solar panels?
- That's not a good idea. Solar panels wear out, and you probably won't know how worn out they are until you buy them and install them. Which is a little bit too late for most refunds. Your best bet if you're dead set on being foolish, is probably some place like craigslist.
- Q: Can solar panels be used in areas with high levels of air turbulence or strong winds?
- Yes, solar panels can be used in areas with high levels of air turbulence or strong winds. However, it is important to ensure that the solar panel installation is designed to withstand such conditions. Proper anchoring and mounting systems, as well as reinforced frames, can help secure the panels and prevent damage or displacement due to wind forces. Additionally, selecting wind-resistant solar panel models can further enhance their performance and durability in such environments.
- Q: I jotted down some notes for my Technology and Architecture class and I'm trying to figure out what i meant when i said 'Treated with gases at extremely high temperatures.' I have NO idea what I was talking about :) Im trying to figure out if what I am talking about is about Silicon, Polychristaline, or a Solar Cell/Panel.
- Some steps in making semiconductors use gases at very high temps, and solar cells might.
- Q: Can solar panels be used in areas with high levels of snow or ice?
- Yes, solar panels can be used in areas with high levels of snow or ice. However, their efficiency may be reduced during winter months due to reduced sunlight exposure and accumulation of snow or ice on the panels. To mitigate this, solar panels can be installed at an angle to allow snow to slide off, or they can be equipped with heating systems to melt the snow or ice. Additionally, regular maintenance and cleaning may be required to ensure optimal performance in snowy or icy conditions.
- Q: i want to join multiple solar panels into a bank so i only need one length of wire, i am going to use diodes to stop them sending power back into the one before it. is this ok or do i need something else?
- That depends on the product of solar panels you buy. I was recently talking to an installing company that sells solar panels that have the DC to AC built into each panel. That way you could simply string them together and add as much as you want as you can afford it. It really isn't much more expensive than any other method of install.
- Q: Can solar panels be used for powering security systems?
- Yes, solar panels can be used to power security systems. Solar panels convert sunlight into electricity, which can be used to power various devices, including security cameras, alarms, and sensors. This allows security systems to operate independently of the electrical grid, making them more reliable and cost-effective in remote locations or areas prone to power outages. Moreover, solar-powered security systems are also environmentally friendly, reducing reliance on fossil fuels and minimizing carbon emissions.
- Q: I need to have more information about what are solar panels. will you help me?
- Solar panels are made up of lots of solar cells. They don't give loads of energy. A line goes around the cells and... that's all I know lol
- Q: Can solar panels be used in areas with high levels of air humidity or moisture?
- Yes, solar panels can be used in areas with high levels of air humidity or moisture. However, it is important to note that excessive moisture can affect the performance of solar panels over time. Therefore, proper installation, regular maintenance, and periodic cleaning are crucial to ensure their efficiency and longevity in such environments.
