- Q: Why might energy from the solar panels sometimes be near zero even in the summer?
- Solar panels are a little like batteries or christmas lights, they are often connected in series, if something is wrong in a string of them, current simply won't flow just like how all the lights in some christmas lights go out if one bulb goes out and you have to find the bad bulb by replacing bulbs one at a time.
- Q: can a small solar panel be charged with lamps?
- yes, although charged is the wrong term. But for every 00 watts you put into the lamps, you will get well less than 0 watts out of the solar array. Well less. .
- Q: I need to build a battery array to use with my solar panels I just bought. I want to be able to store enough energy to be draw from it at night, possibly around the clock. Is there a down side to using the deep cycle battery I bought from autozone and 6 or 7 more just like it, or do I need to get some other battery?
- There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
- 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?
- A study by the US Department of Energy shows that, depending on your solar panels, the energy payback is to 4 years. Solar panels usually last 25 years, so solar manufacturing is very green. That said, if you buy American made panels, it saves more carbon from the transport costs. Something to consider in choosing your panels.Actually, most panel manufacturers will recycle the panels after you’re through in 25 years. If they don’t, don’t buy those panels. However, it’s hard to say whether people will actually recycle them because most panels are still being used today. So it’s up to you find out about the manufacturer’s panel recycling program. From what I understand, they will come to you and take them away at no charge.
- Q: I am in the market for buying a home. There is one for salke that actually has solar panels on top. How are they used? Do you need to pay for gas and electric still. Does it really light up the house and keep it warm. WHat about the AC keeping hte house cool in the summer does it work for that too? Please explain in solar for dummy terms. I haveno clue about solar panels other thatn the fact that it needs sunlight to run.
- I think that rustoria67 bumped his head on some thing. There are thousands of homes using only solar panels to power their homes, and it no way near an acre of them. With the right setup Kw of panels will work. Remember one can't bring a boat to an airplane race and hope to win. Look at this link.
- Q: i need to make a mini-solar car which shouldn't cost much. it's for my science project. for now, i just found out how to make a solar panel using copper oxide, but it does not generate enough power to power up the engine of the toy car [ the small engine they used in the toys, like from TAMIA]
- There are several types of solar panels. If you mean photovoltaic panels for generating electricity, that is a really advanced project that few amateurs are equipped to do. In the long run, it will be a lot cheaper and easier to buy factory made PV panels. You can try building one by sandwiching an array of photovoltaic cells between a sheet of glass or plexiglass and a sheet of aluminum. Remember that this assembly must be able to withstand great heat, and it must be sealed to make absolutely sure it does not leak.
- Q: How hard is it to install solar energy panels on your house? Is this a reasonable way to produce 00% of your house's energy? Is there any danger?
- Yes, but it is still very expensive at the moment. Look into solar leasing where you rent your roof to a company that installs and owns the panels and pays you a portion for surplus energy beyond your usage. I looked into going off the grid a couple years ago and based on our usual consumption it was going to take a $40,000 investment with a 0 year payback for panels, inverter, and storage batteries.
- Q: Can solar panels be installed on flat roofs?
- Yes, solar panels can be installed on flat roofs. In fact, flat roofs are often considered ideal for solar panel installations due to their easy accessibility and the ability to optimize panel positioning. However, it is important to conduct a structural analysis and ensure proper waterproofing measures are taken during the installation process.
- Q: Can solar panels be damaged by hail or strong winds?
- Yes, solar panels can be damaged by hail or strong winds. Hail can cause physical damage to the panels, such as cracking or shattering the glass surface. Strong winds can potentially dislodge or loosen the panels, leading to structural damage or detachment. To mitigate these risks, solar panels are designed and installed to withstand certain weather conditions, but extreme hail or exceptionally strong winds can still cause damage.
