- Q: Can solar panels be installed on a metal roof?
- Yes, solar panels can be installed on a metal roof. In fact, metal roofs are often considered ideal for solar panel installation due to their durability and longevity. The metal roof provides a strong and stable surface for mounting the panels, and the sleek design of the panels can complement the aesthetics of the roof. Additionally, the metal roof's reflective surface can help enhance the overall efficiency of the solar panels by bouncing sunlight back onto them.
- Q: Can I install my 2v solar panel straight to battery to charge the battery on my 989 ford ranger?
- If you were going to do that it would have to be the right size solar panel and you would need a solar battery charger so it doesn't fry your car battery
- Q: Can solar panels be installed on a shopping mall or retail center?
- Yes, solar panels can be installed on a shopping mall or retail center. Many commercial buildings, including shopping malls and retail centers, have ample roof space that can be utilized for solar panel installations. Installing solar panels on these buildings can help offset energy costs, reduce carbon emissions, and provide a renewable energy source. Additionally, it can also serve as a visible demonstration of the business's commitment to sustainability and environmental responsibility.
- Q: I want to get solar panels but not spend 20,000!! I found out that you can get a panel to run only your AC unit, I also found something that will run my pool pump! Anyone own either of these? How did you do? Where did you go? How much was it, and was it hard to install?
- Solar panels are very expensive and take many years to pay for themselves. You'd be better off contacting your congressmen to lift bans on Nuclear and other producers of electricity. That would lower the costs and save much more than the hassle of hooking up solar power and batteries etc.
- Q: Can someone explain to me how solar panels can be used as modern architectural attributes? please help
- They aren't considered attributes - electrical solar panels are expanses of gray and aluminum covered with glass and water heating panels are expanses of black covered with glass. To cover the cost of investment they must be mounted at the best angle for the location and climate throughout the year and therefore may dictate the form of the roof (if sloped as on residences) or may not be visible in an architectural sense (if positioned on a flat roof of a commercial building.) No matter where placed, provision has to be made for safely accessing them for repair and maintenance.
- Q: Can solar panels be installed on concert venues or music festivals?
- Yes, solar panels can be installed on concert venues or music festivals. In fact, many venues and festivals are increasingly adopting solar power as a sustainable and renewable energy source. Solar panels can be installed on roofs, canopies, or even on the ground surrounding the venue, providing clean energy to power the event and reduce its carbon footprint.
- Q: Can solar panels be installed on a winery or vineyard?
- Yes, solar panels can be installed on a winery or vineyard. In fact, many wineries and vineyards have embraced solar energy as a sustainable and cost-effective solution to power their operations. The large open spaces, such as rooftops or unused land, provide ample opportunities for installing solar panels, which can help wineries and vineyards reduce their carbon footprint and lower energy costs.
- Q: i need to make a solar panel model for a project in science and i would like to know how to build a easy model at home that wont cost alot
- There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.
- Q: Can solar panels be used in areas with high levels of noise from transportation?
- Yes, solar panels can be used in areas with high levels of noise from transportation. Noise pollution does not affect the functionality of solar panels as they primarily rely on sunlight to generate electricity. However, it's important to ensure that the panels are properly installed and maintained to maximize their efficiency and minimize any potential disruptions caused by noise pollution.
- Q: I'm looking into buying solar panels, there are all kinds of ranges of energy output...but my question is, when ti says...say 50 watts of power...does that mean 50 watts a day, an hour, a minute, what?
- A 50-watt rating means the panel will produce 50 watts as long as the standard conditions are maintained. So if you had this bright sun and cool temperatures for 6 hours, the panel would deliver 50 x 6 = 900 watt hours, or a little shy of kilowatt-hour. Kilowatt-hours (kWh) is the reading on your electric bill. However, like most advertising, the 50-watt number is not realistic. They assume that the air surrounding the panel is very cold. 25 watts is a better number to use for this size of panel for engineering purposes.
