Q:i trying to make a solar panel. right now i dont have money to go and buy a copper sheet. so can i make it out of aluminum foil. if there is a way please tell me how. and what do i use for wires. i making this to charge batteries.
Presumably you plan to create a focused parabolic reflector and have it oriented to heat the bottom of a pan. It will obviously need to be larger than the pan in order to gather sunlight outside of the pan's shadow, as well as gather and concentrate enough light onto the bottom of the pan to heat its contents. If you use black paint on the bottom of the pan, make sure it's high temperature paint (available at auto supply stores, often used to paint engine blocks and exhaust manifolds). Yes, a cover on the pan will make it hotter.
Q:. Does it really only cost $200 in contrast to $5000 or more?2. How much would it cost to build panels that would energize an entire average household? (washer, dryer, water heater, lights, fans, a/c)3. Is there a place to get the info on how to make them for free instead of paying E4E?4. Are the professional solar panels better? more efficient? 5. Will the electric company in So. Cal. really pay you?6. Do you have to be certified to do this professionally? or an electrician? If so what schools teach it?7. Would wind generators be of any use in So. Cal.? I mean don't you really need to get the fan spinning to get energy?8. Are there any extra unseen costs? (tools, energy converter, ect)9. How much is it to get an electrician to hook you to the grid?0. Is it better to hook to batteries or the grid? Pros, cons, why?

Q:Can solar panels be installed on a pergola or gazebo structure?
Yes, solar panels can be installed on a pergola or gazebo structure. However, it is important to ensure that the structure is sturdy enough to support the weight of the panels and that they receive adequate sunlight for optimal energy production. Additionally, proper wiring and mounting techniques should be followed to ensure safety and efficiency.
Q:This is for my science project and i cannot figure it outWe assumed that blue light shining on a solar panel would give off the higher volt reading because it has the shortest wavelength and the highest energy, but it was actually the lowest. Why does this happen? Im very confused And cant find the answer anywhere.... ,thank you!!
It is based on what the solar panel is made out of. Many of them will generate electric into the NIR region.
Q:Just curious.
Solar panels are built with light-sensitive panels. These panels soak up the energy from the sun's light. This energy is changed to electric power. This power is stored in batteries to use whenever / wherever it is needed.
Q:How do solar panels withstand hail and other extreme weather conditions?
Solar panels are designed to withstand various weather conditions, including hail and extreme weather. They are typically made with durable materials such as tempered glass, which is highly resistant to hail damage. Additionally, the panels undergo rigorous testing to ensure their ability to withstand high winds, snow loads, and extreme temperatures. The frames and mounting systems used to secure the panels also contribute to their resilience against severe weather. Overall, solar panels are built to be robust and reliable, enabling them to endure hail and other extreme weather conditions.
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:. Do they scratch easily? How do I remove snow from them without scratching them?2. What does the upkeep of many solar panels consist of? I want to have my electricity completely off of the grid.3. Are all solar panels made from the same material, regardless of size?
. Do they scratch easily? No How do I remove snow from them without scratching them? Just wipe the snow off 2. What does the upkeep of many solar panels consist of? Clean them with tap water and paper towels once a month. 3. Are all solar panels made from the same material, regardless of size? Basically the same.
Q:Can solar panels be installed on a government building or facility?
Yes, solar panels can be installed on a government building or facility. In fact, many governments around the world have been actively promoting the use of solar energy by installing solar panels on their own buildings. This helps them reduce their carbon footprint, save on energy costs, and set an example for others to follow in adopting renewable energy sources.
Q:Can solar panels be used for charging electric scooters?
Yes, solar panels can be used for charging electric scooters. By connecting the solar panels to an appropriate charge controller and then to the scooter's battery, solar energy can be harnessed and stored to power the scooter, providing a clean and renewable source of energy. However, the efficiency of solar panels may vary depending on various factors such as the size of the panel, sunlight availability, and the scooter's power requirements.
