- Q: Can solar panels be installed on a concert venue or entertainment facility?
- Yes, solar panels can be installed on a concert venue or entertainment facility. In fact, many venues are increasingly adopting solar energy as a sustainable and cost-effective solution. Solar panels can be installed on rooftops, parking lots, or open spaces around the venue to generate clean and renewable electricity. This not only helps to reduce the environmental impact but also saves on energy costs in the long run.
- Q: I have a 20 watt solar panel that I want to set up. I need to connect it to the solar controller but do not know what cable to use. I plan on adding more solar panels down the line. What would be the best cable to use?
- on the controller, it writes which would be related with image voltaic panel which would be related with battery which would be related with load all of it write on the image voltaic controller. only see the controller
- Q: Can solar panels be installed on a sloped roof?
- Yes, solar panels can be installed on a sloped roof. In fact, sloped roofs are a common choice for solar panel installations as they offer an optimal angle for capturing sunlight. However, it is important to consider the pitch and orientation of the roof to ensure maximum efficiency and proper installation.
- Q: I would like to know how do you build a solar panel?
- At first, you will need about one square foot of thin copper plate, two alligator clips and short leads of wire, a wide mouth glass jar, tap water and salt. Cheers,
- Q: Why are they placed there? How come they aren't placed on the floor or window.My fiance and I are interested in putting solar panels on our new home. I was really curious and google wasn't giving me the answer. My roof is pretty small in our new house and I don't think it would fit there. Why is it usually placed there and is there another place? You will be chosen as best answer if you answer all my questions. Thanks in advance, and I would appreciate if nobody is rude. Otherwise, I will have to report abuse.
- The roof is the most popular location for panels, I'd imagine because: ) The space is not otherwise being used. Panels in the yard would take up play space, or shade the garden or lawn. 2) The roof is usually more free from shadows because it's high up. Something low to the ground could more easily be shaded by trees, fences, or nearby buildings. 3) The roof often has a built-in tilt that is more ideal for panels. Take a good look at your roof, especially if there is a south-facing side. The roof could be bigger than you think. Only 0% of our roof area is dedicated to solar panels, and that keeps up with our yearly electrical usage.
- Q: Can solar panels be installed on windows or glass surfaces?
- Yes, solar panels can be installed on windows or glass surfaces. These solar panels are known as transparent or semi-transparent solar panels and are designed to allow light to pass through them while still generating electricity. They are commonly used in buildings where traditional solar panels may not be suitable or aesthetically pleasing.
- Q: I riped two solar panels out of some solar light and tested them. I found out that they both produce 2 volts(I have no idea on the watts or amps). Iquot;ve hooked them up to an electric motor that can be driven by a AA battery, but when I hook the solar panels up to them nothing happens. What is wrong?
- The solar cells you have are not providing enough current to operate the motor. There are special low power motors which can operate directly from a solar cell but it sounds like you do not have one of these. Instead you have a common .5V DC hobby motor which requires substantially more current to operate. You can use the original circuit to charge the batteries and use the charged batteries to run the motor. The batteries would be able to supply enough current to operate the motor, but for a limited time. 8 hours of charging might give you less than 5 minutes of motor operation. An LED will draw about 20ma. In a solar light such a small current draw from an LED or two can provide hours of light. A Small DC motor might easily require 300ma to run and over 500ma to start. Running a motor from the same battery at over 5 times the current draw will result in less than /5 of the run time compared to the low current LED. So if an LED operates for 300 minutes the motor would run for less than 20.... The small solar cell size cannot provide enough current to operate the motor directly. Only by slowly charging a battery first would you be able to use the collected and stored Solar energy to operate your motor.
- Q: Can solar panels be used for irrigation systems?
- Yes, solar panels can be used to power irrigation systems. Solar energy can be harnessed by the panels and converted into electricity, which can then be used to run pumps and other components of an irrigation system. This renewable energy source offers a sustainable and cost-effective solution for powering irrigation systems, especially in remote or off-grid areas.
- Q: does anybudy know about solar panels? plz reply me
- How Solar Cells Work by Scott Aldous Inside This Article . Introduction to How Solar Cells Work 2. Photovoltaic Cells: Converting Photons to Electrons 3. How Silicon Makes a Solar Cell 4. 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: I just connected my 5 Watt 2V solar panel directly to my 300 Watt 2 inverter. It worked for about 2 minutes then it popped (sparks, smoke etc)! What the hell did I do wrong? I thought the solar panel was 2 volts? Can someone with experience with these things help me out?
