Q: Can solar panels be installed on sloped roofs?
Yes, solar panels can be installed on sloped roofs. In fact, sloped roofs are one of the most common locations for solar panel installation. The angle and direction of the roof can affect the efficiency of the panels, but with proper installation techniques, it is possible to maximize their energy generation potential on sloped roofs.
Q: I'm curious to know if the small solar panels on a calculator (ie TI-32) could produce a voltage similar to what is used in a single-use (disposable) camera, approximately 4V.
It isn't Volts that matter if you're trying to put the calculator solar panel on the camera. It would be the amps. The calculator's solar panel will put out however many volts or very close to what the battery puts out. If you want you can test it out with a Volt/Ammeter. You see, those cameras use 2 double A batteries. They are going to put out a higher current than the small dime shaped battery in the back of your calculator; a higher voltage perhaps too. Those disposable cameras have a photo flash capacitor in them that has to charge. You can hear them charge up when you tell it to turn on the camera's flash. Sounds like a winding then the little orange light comes on. That light means the capacitor is charged. You SHOULDN'T be able to change out the batteries in the camera with a solar panel from a calculator without having to wait days for that flash capacitor to charge. Sorry. EDIT: HOWEVER, you can take multiple solar panels and wire them in a parallel circuit to get more current(amperes) or wire them in a series circuit to get a higher voltage. If you were to do this you could power whatever you wanted with them. Even your house if you were to get a rectifier to convert the power from DC to AC.
Q: Can solar panels be installed on parking lots or garages?
Yes, solar panels can definitely be installed on parking lots or garages. In fact, these areas are often ideal for solar panel installations due to their large, open spaces and exposure to sunlight. Installing solar panels on parking lots or garages not only helps generate clean energy, but also provides shade and protection for vehicles, making it a practical and sustainable solution.
Q: Can solar panels be used for powering outdoor events or festivals?
Yes, solar panels can definitely be used to power outdoor events or festivals. They are a sustainable and reliable source of energy that can provide electricity to run lights, sound systems, food stalls, charging stations, and other equipment needed for such events. Additionally, solar panels can be easily set up in open areas, making them ideal for powering outdoor gatherings without the need for grid electricity or noisy generators.
Q: Do solar panels require permits for installation?
Yes, solar panels generally require permits for installation. The specific requirements and regulations for obtaining permits may vary depending on the location and local building codes. However, in most cases, permits are necessary to ensure compliance with safety standards, electrical codes, and zoning regulations. It is advisable to consult with local authorities or a professional solar installer to determine the exact permitting process in a specific area.
Q: I have four power packs for solar lights. They have 3 AA .2volt batteries of 2450 mAh capacity installed in series for a total supply voltage of 4 volt maximum for the lights. I want to charge all four packs at once off a single 6 volt solar panel. With the four packs wired in parallel, what capacity output (wattage) panel do I need to charge the batteries in an 8 hour day?
3 cells in series makes a 3.6volt 2.4AH battery. You multiply the volts but not the capacity. In parallel would be .2volts, triple capacity. So 4 packs in parallel is 9.8AH. Rule of thumb for charging a flat battery is divide capacity by 0 for amps and charge for 5 hours. amp at 6 volts is doable, that would be 6 watts People who make batteries and solar cells usually over-rate them so I doubt that a solar panel of less than 20 watts rating will fully charge these batteries if they are flat. I'd google to see how you might control the charge current with a simple circuit.
Q: i'm making a small solar panel powered fan but it cant run the cellphone vibration motor even i have place two x2 solar panel.
Did okorder / . Possibly this could immediately instruct each and every one!
Q: Can solar panels be installed on historical landmarks or monuments?
Yes, solar panels can be installed on historical landmarks or monuments, but it requires careful consideration and planning to ensure that the installation does not compromise the historical integrity or aesthetic value of the site.
Q: Okay, so I have a science fair coming up soon and I need help with my project. SO - What should I use to demonstrate with the propeller? A toy boat? Plane? And I only have mini solar panels ; so how do I put the solar panels on the toy boat/plane to make the propeller move off of the sun's energy? Thanks. Steps please!
Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
Q: i just took a trip to florida, they are cutting down anything that doesnt float and putting up buildings. Most of these cost a bundle, bill gates may pay cash for them, but most people will have many payments. Since pools, satellite dishes, and docks if near the water seem to be standard issue, why not a couple solar panels and water heater. It is florida after all, and if you are allready paying a half million or so for a house, what is another 0k gonna mean to you. Why dont they make it mandatory to include these on all new housing and condos and businesses. With that many the price would come down quickly and pay for itself long before the house is payed off and/or florida is flooded due to global warming.
Because not only does that just make TOO much sense, it comes down a cost factor, even though, as you say, what's another couple K for saving the environment. Sad thing is, even though they *JUST* figured out that global warming (loved that news story a couple weeks ago) is caused by humans abusing the earth, Americans especially just don't care enough. Our culture is so spoiled now that we refuse to be told what we need if it's not what we want or if it will cost us $5 extra.
