- Q: Can solar panels be used in areas with high humidity?
- Yes, solar panels can be used in areas with high humidity. While high humidity may affect the efficiency of solar panels to some extent, they can still generate electricity. The performance of solar panels in humid environments can be optimized by using materials that are resistant to moisture and by ensuring proper installation and maintenance.
- Q: my dad met a guy representive for a solar panel company at a swapmeet Scam?
- Hard to say. Solar panels are becoming more common these days. May want to ask if the vendor is licensed and bonded contractor (if he's doing installation as well as panel sales). Find out the name of the equipment that this guy is selling (panels and other hardware) and do a search. For that matter, get the guys name and do a search on it to see he pops up elsewhere.
- Q: My project needs to build a thermal solar panel that would be used as a demonstrational rig. The dimensions i am allowed do not allow me to use a normal thermal solar panel so i have decided to use the heat exchanger from the back of a fridge. Although this is possible to use what equation would i use to prove the power of the sun would actually heat up the water. More importantly when the rig is demonstrated to students, they will need to be able to determine if the raise in temperature given by the thermometers is what should be given. Variables of the rig will include: Angle of the panel, Light intensity, Direction of panel, and more importantly the flow rate of the water travelling through the pipes. What equation includes those variables (change in temperature, flow rate) and would allow me to incorporate the angle of the panel. The light source would be a lamp so i would also need to know how much of the energy from the lamp is actually being used by the panel?
- If you only use it for demonstrational . 75W-00W small solar panels would be that you are looking for, you can use it heat up the water. With simple guide you can do it yourself easily and cheaply.
- Q: I have a solar panel I bought for a diy project and it has a small plug on the end of it, but I need to remove this plug to expose the positive and return wires so I can solder a bunch of stuff together. How do I cut off the plug without shorting out the solar panel when I make the cut? Can I just leave it in the dark a while before cutting? I don't think I can remove the wires from the solar panel end before cutting.
- A solar panel doesn't store energy. As soon as the light stops, the current stops instantly. If it's a 200-watt panel or more, it won't be harmed by a short circuit, but it might be good to turn the panel over or cover it with cardboard before working on it. The spark can slightly mar the contacts. Doing the work indoors is enough to cut down the current, too. For a 60-watt panel or less, I wouldn't even worry about the spark, the power output is too low to do any damage.
- Q: Can solar panels be installed on a rental property?
- Yes, solar panels can be installed on a rental property. However, it is important to check with the property owner or landlord before proceeding with the installation. Some landlords may have specific policies or restrictions regarding modifications to the property, so it is necessary to obtain their permission and potentially negotiate the terms of the installation.
- Q: Are there solar panel systems that I can plug directly into my house to help reduce my electricity bill? If so, are they very expensive? Any help would be greatly appreciated!
- I wish it was that easy! Maybe it will be soon. But at this time, no, there isn't. And if you have a solar collection system, you have to have a way to store the energy when you're producing more than what you are currently using. That usually involves an expensive battery array. But it's necessary. The power coming directly from the solar panels will be erratic and sending it to the battery array for storage and then use allows for the home to draw a consistent level of power. And this battery system also allows for storage of electricity for use when the sun isn't shining like at night. The system should be set up to use your power first, then go to the grid. It should also allow for distribution to the grid when your system has stored all the power it can and that's when your meter will run backwards and the power company will be paying you! There are a lot of federal and state income tax rebates for alternative energy installation costs. Check out what Oregon might toss into the package along with the Feds and see where you might come out.
- Q: How do solar panels impact the roofing material's lifespan?
- Solar panels can actually extend the lifespan of roofing materials. They act as a protective layer, shielding the roof from various weather elements like UV rays, hail, and rain, which can cause damage over time. Additionally, solar panels can help regulate the temperature of the roof, preventing excessive heat buildup that can accelerate the degradation of roofing materials.
- Q: The battery is 9ah and the solar panel is 20w
- You need a switch mode voltage converter, made to input 2 to 20 volts, and output around 7 volts. Some cell phone chargers can do that, or be modified for that voltage. Option B is to get another battery and use the system at 2V, and regulate that to 6 or 5 volts for charging (you can directly use your car charger), with switch mode regulators. I would find that system to be more flexible. Getting an 8Ah would leave extra capacity. BTW, for a 9AH battery, 20W is kid of big. I have a 36Ah battery and a 20W panel, and that is good for it.
- Q: Can solar panels be damaged by hail or other flying debris?
- Yes, solar panels can be damaged by hail or other flying debris. Hailstones, especially those larger in size, can potentially crack or shatter the glass surface of solar panels, impairing their function. Similarly, flying debris during storms or extreme weather conditions can also cause physical damage to solar panels, affecting their efficiency and performance. To mitigate these risks, solar panels are designed to withstand certain levels of impact, and some manufacturers even conduct rigorous testing to ensure their durability in harsh conditions.
- Q: What makes them stop working after a while?
- You can search on solar panel failure mechanisms for scholarly works. Amorphous silicon thin-film panels go through an annealing, and power drops off after a couple years. This includes most of those flexible rubber mat type panels. That's why those are not used on serious installations. Serious panels intended for rooftop service generally come with a 25-year warranty, suggesting that the technology is more reliable than your washer, dryer, TV, computer, dishwasher, or water heater. One brand of panel had trouble about 0 years ago, but the manufacturer replaced all that were turned in, even paying shipping both ways. It was a problem with that particular model, not the technology. Our polysilicon panels have been on the roof for 3 years, now, and I've seen no sign of wear, yet, either electrically or mechanically.
