- Q: Rooftop solar panel (not sure if rubber or plastic?) has leak arising from thin vertical crack in panel about long. Any ideas for repair?Thanks.
- Depending on the material and operating temperature of the panel, it MAY be possible to fix it very simply and easily by applying Hot Glue Gun adhesive over the cracked area. The high temperature glue gun adhesive melts at approximately 60 degrees Farenheit, and if the collector temperature does not quite reach, or exceed that operating temperature, then that repair method should work. Another possibility is an aerosol spray can product called LeakEnder. This is usually available at your local hardware store, or the major home improvement centers [like Lowe's, Sutherland's, Home Depot, McCoy's, etc.]. After preparing the area to be patched by cleaning, you just spray the LeakEnder patching material on the crack and an eighth of an inch or so around. IF the operating pressure or the collector is very low, it MAY even be possible to patch the leak with nothing more than a narrow strip of DUCT TAPE!!!!! Another possibility, but unless carefully accomplished is to weld the crack with a Soldering Gun and some scrap plastic from packaging material. The problem with this fix is that you must be very experienced in application of heat from the Soldering Gun, OR you will melt a larger hole in the collector tube than the crack was. Regardless of patching method, it is CRITICAL that the cracked area to be patched MUST be CLEAN and DRY BEFORE applying any patching material. Good luck!
- Q: Hi, I am starting to get curious about the pros/cons of installing solar panels - has anyone done it and is it worth it?
- Solar is mroe expensive than just about every other form of generation for a centralized plant, but can still be cost-effective for a consumer living in the right place. This is because while a coal-fired plant may produce electricity for 2-3 cents per kWh, by the time it's marked up to retail, distributed, and taxed to get to a residence, it may be 5 cents per kWh - a figure which solar can match in many places.
- Q: I was wondering if they create other forms of energy besides electrical that is unwanted. Like heat due to the friction of something, or sound. Also why is a solar panel not able to collect 00% of the energy that is striking its panels. And how could the efficiency of this be hypothetically improved.
- Science. The best solar panels we have only get like 22% of the sunlight for conversion into energy. That is simply the best they know how to make with current technology. And for that your talking about a mobile panel that tracks the sun as it moves at the equator. A solar panel in say Canada is lucky to get 0% even on a sunny day. But even if a solar panel got 00% efficiency, it's still not a lot. Sunlight is too diffuse to be a good power source, and you'd need to cover lots of ground to get power. Worse, you can only get power when the sun is out during the day. So for power at night you'd need a battery, or another source of power. The 'newest' idea is to capture sunlight to make 'lasers' that boil water, to turn turbines and make electricity. They cost way more then they are worth right now though...
- Q: what direction should solar panels face to get the best exposure of the sun.
- depends on the exposure.[trees other buildings, etc.] If you don't have trackers to keep the panels facing the sun , just plain old due south ,I've heard, is best for best average exposure.
- 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.
- Just cover the panel and cut the wire the voltage will be so low it would be like shorting out a battery
- Q: Can solar panels be used to power outdoor lighting?
- Yes, solar panels can be used to power outdoor lighting. Solar-powered outdoor lighting systems typically consist of solar panels that collect and convert sunlight into electricity, which is then stored in batteries. This stored energy is used to power the outdoor lighting fixtures at night or in low-light conditions. This sustainable and cost-effective solution eliminates the need for traditional electrical wiring and reduces energy consumption.
- Q: I'm writing a lab and I have to put information about solar panels in it. The history, who started them, why they are useful etc. any good sites that can help me?
- Good question, but I don't think big oil likes solar panels.
- Q: Can solar panels be used in areas with high levels of saltwater exposure?
- Yes, solar panels can be used in areas with high levels of saltwater exposure. However, it is important to take certain precautions to prevent corrosion and maximize their performance. This can be achieved by using materials that are resistant to saltwater corrosion, such as stainless steel or aluminum frames, and encapsulating the solar cells with durable and protective coatings. Regular maintenance and cleaning can also help ensure the longevity and efficiency of solar panels in such environments.
- Q: i wanted to buy solar panels but this guy told me one will just power one light bulb what i want to know is how much thay cost and is it true tat if more power leaves your house than goes in the power company has to send u a cheek
- Whether you get a check for excess power generation depends on where you live. Some places in Texas will do that, the largest 3 utilities in California will not. The bottom line is that you should not expect solar panels to be a moneymaker. They may or may not be a money saver in the long run, depending on your situation. Solar hot water can pay back in a few years, if it displaces an electric water heater, and if it's in a location that is generally warm. Solar electric usually takes longer to pay back, if ever. The best payback is for those who have expensive electricity already, and are also in a sunny area. As an example, our system cost $2k net, and saves us about $600 / year in electricity (i.e., all our usage). It will take 20 years to pay back the installation cost, but I admit we did it for more reasons than the financial.
- Q: Do solar panels increase property value?
- Yes, solar panels have been found to increase property value. Studies have shown that homes with solar panels tend to sell at a higher price and faster than those without. Additionally, the potential for reduced energy bills and the positive environmental impact of solar energy can make a property more attractive to potential buyers, thus increasing its overall value.
