Q: I am doing a project on solar energy at the moment and I was just wondering how.
my theory is that when sunlight hits the panel it excites the electrons from the rays there by making them move more quckly and attract them to a source with less elctrons making the panel positiveli charge and the electron collector negatively charged thereby connecting the negatively charged particles to which ever body it wishes to donate it too thereby causing electric charges
Q: Can solar panels be used in areas with high levels of humidity?
Yes, solar panels can be used in areas with high levels of humidity. While high humidity can affect the performance of solar panels to some extent, it is not a significant barrier. Modern solar panels are designed to withstand various weather conditions, including high humidity. In fact, some studies suggest that solar panels can even benefit from the occasional rain or humidity, as it helps in cleaning off dust and dirt, thereby improving their efficiency. Regular maintenance and cleaning can further mitigate any potential impact of humidity on solar panel performance.
Q: Has anyone actually used those kits online like energy4green or earth4energy to build their own solar panels or windmills? I'm so tempted but with my budget can't afford to waste any money. They have a 60 day money back policy but that doesn't include the money used to buy the supplies to try and build the things. My electric bill is almost $300 a month due to my stay at home disabled veteran husband who went from Utah snow to Florida sun and he has to have the AC on really cold. If anyone has actually built one can you tell me of your experience and if it actually is worth the money? I do lots of D.I.Y. projects but am a novice with electric besides installing a ceiling fan and changing out a light switch.
Electric panels are not feasible for most people. They are two super thin layers of polarized material. When the sun hits them electrons move from the first to the second layer with an amount of force. You can't duplicate that at home. What you could do is setup solar heating panels and run them against a Stirling engine. This technique is typically more efficient than normal electric panels anyway in industry. They have heat on one side and cold on the other to generate force. Hook that to any generator to produce electricity. If you are successful building a home system, blog about it, others will want to know precisely how you did it.
Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
You should be fine with the series as long as you use a multimeter and verify configuration Get a charge controller. Will be worth the small cost and prevent many issues.
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, the efficiency of solar panels may be reduced during winter months due to reduced sunlight exposure. It is important to design solar panel systems in snowy regions with proper tilt and orientation, as well as implement measures like snow removal to ensure optimal performance.
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]
Have okorder . This will absolutely save yourself!
Q: I am planning to run a couple of dc motors on solar current. I have a couple of 450mA 4V, 200mA .5V, 00mA 9V solar panels with me. I need to run a pair of .5A 9V motors. Suggest me a circuit along with other equipments I might require. For your info, I am trying to build a solar powered drone / UAV
I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
Q: Can solar panels be installed on a hotel or hospitality facility?
Yes, solar panels can be installed on a hotel or hospitality facility. In fact, many hotels and hospitality facilities have already embraced solar energy as a renewable and sustainable source of power. Installing solar panels can help these establishments reduce their carbon footprint, lower energy costs, and demonstrate their commitment to environmental sustainability.
Q: if i was to put a solar panel (sp) just outside of the earths atmosphere ans another solar panel (sp2) 0km away towards the sun. which one would generate more power (sp or sp2)? and how much more? is there a ratio to work out the power output and distance from the sun? would the 0km distance between the panels make a large difference in power output?many thanks in advance
You do realize that the sun is 50 million km away don't you?
Q: Can solar panels be installed on waste treatment plants?
Yes, solar panels can be installed on waste treatment plants. Waste treatment plants often have large open areas, such as rooftops or unused land, which can be utilized for installing solar panels. This can help the plant generate clean, renewable energy, reduce its reliance on grid electricity, and lower its carbon footprint. Additionally, solar panels can also provide shade and protect the facilities from extreme weather conditions.
