- Q:Is there a free site or resource that will teach you how to do this? Hopefully step by step and tells you how to buy all the parts ect?Which is the best resource for sale earth4energy, homemadeenergy, ect? Do they actually work and also as well as those which are professionally done?They say it will cost under $200 for a panel, but how much will this panel actually produce I mean how many panels would you have to make to produce 00% of your homes energy?
- there are plenty of free sites that tell you how to install your own solar panels. Just google diy solar panels. as to how many panels you need, it depends on what all you're trying to have them run.
- Q:okay so my teacher is trying to install a solar panel but we have a problem we don't know where to ground it because it will be a movil house. guys do you have any ideas?
- Typically you mount it with the frame as a ground and you ground the frame with a wire or cable tied into the ground when the mobile home is parked.
- Q:Can solar panels be installed on metal roofs?
- Yes, solar panels can be installed on metal roofs. In fact, metal roofs are considered to be an ideal surface for solar panel installation due to their durability and compatibility with the mounting systems used for solar panels. Metal roofs provide a sturdy and stable foundation for the panels, making the installation process easier and more secure.
- Q:What is the efficiency of solar panels?
- The efficiency of solar panels refers to the amount of sunlight that is converted into usable electricity. It is typically measured as a percentage and can vary depending on factors such as the quality of the panels and the location of installation. On average, modern solar panels have an efficiency range of 15% to 20%, with some advanced models reaching up to 25%.
- Q:where I can find solar panel the has 4.8 volts? Like those solar walkway light or something that has 4.8 volts solar panel.Do you think I can get it from home depot?

Anatomy of a Solar Cell 5. Energy Loss in a Solar Cell 6. Solar-powering a House 7. Solving Solar-power Issues 8. Solar-power Pros and Cons 9. Lots More Information 0. See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
- Q:quot;Does it take more energy to produce a solar panel than what the same solar panel can generate in its useful lifetime?quot;
- No. That lie is put out there by people who would lose out if solar panels ever became widely used. It does take about as much power to produce them as the panels make in 2 years in a good location, but considering their useful lifetime is at least 20-30 years, that isn't much. Wind power produces as much power as is used to create the windmill in 7-9 months in a decent location. Neither will ever produce as much power as they required to be made if placed in the wrong location, like in the shade or a non- windy area. No coal plant would ever make as much energy as it took to build it if no coal were provided either.
- Q:I am told there are night vision goggles to see at night due to invisible light still hitting earth. I am also told that there are other beams, x-rays etc hitting earth.Why couldn't they invent a solar panel with dual power in the day?It could harness both visible and invisible light, and at night be single?Anyone know why they can't make an invisible light solar panel?Is this possible?What happens if future cars have night vision windshields instead of lights?
- They are actually working on building photovoltaic panels (Photovoltaic is actually the correct term for sunlight--electricity. Ordinary solar panels are those that use sunlight to heat water) that harness a larger range of wavelengths. From what I can gather the problem is either finding a material that absorbs more wavelengths, or finding a way to get multiple materials to coexist in a single panel. This situation will no doubt improve over time as new things like Nanotechnology give us the ability to create much more complex substances designed at the molecular level for light capture. Panels that can harness a wider range of the spectrum do exist, but the technology is in its infancy, and therefore expensive and not widely known. This isn't too surprising when you consider that Photovoltaic technology itself hasn't been in the mainstream all that long. I am a bit doubtful of photovoltaics that work at night, for the simple reason that at night there is less of *every* kind of energy falling on earth. Less visible light, infrared, etc. Infrared just happens to be particularly good at giving away hot objects, which is how Night Vision goggles work. For the same reason, a night vision windshield might be a very useful tool, but it would still have difficulty picking out colder objects, and those that reflected less infrared light. In other words, you might see cars and pedestrians, but you could easily miss the upcoming embankment 0.o .
- Q:Can solar panels be used for powering a telecommunications tower?
- Yes, solar panels can be used to power a telecommunications tower. Solar energy is a renewable and sustainable source of power that can efficiently generate electricity to meet the energy demands of a telecommunications tower. By harnessing the sun's energy through solar panels, the tower can operate off-grid and reduce its reliance on traditional power sources, making it more environmentally friendly and cost-effective in the long run.
- Q:Simplfy it so i can understand pls and put it in stages such as . sun hits solar panel plsHow many different types of solar panels are there?
- Solar panels is built of the solar cells in it..these cells are typically made of paper thick Silicon or Germanium metal (called semiconductors).When light falls on these solar cells the energy recieved from the light (photons)is used to emit electrons due to the nature of semiconductor material. These electrons being of negative charge are attracted by opposite positive charges or there is current flow from cathode to anode on these cells.This small electric charge generated is used to store in the battery connected...more the number of solar cells more the electricity generated .
- Q:Can solar panels be used in countries with limited sunlight?
- Yes, solar panels can still be used in countries with limited sunlight. While solar panels are most effective in areas with abundant sunlight, they can still generate electricity even in regions with less sunlight. Advances in solar technology and the ability to capture diffuse sunlight have made it possible for solar panels to be used in countries with limited sunlight. Additionally, the efficiency of solar panels has improved over time, allowing them to generate electricity even in low-light conditions.
