- Q: this solar panel i saw was for 500 dollars(i get a 25% discount)and i was curious will they produce electricity? or just heat?what do they do?is it a good investment?here is a link to the one i would like, no reviews but it looks new to the site.
- Also crystalline silicon, but almost triple the power. I would suggest that you have a lot more research to do before just buying a panel. A single panel like that isn't immediately useful unless you have a device that takes exactly that voltage, and is not critical. A solar water pump might fall into that category. For anything else, you would need additional equipment, such as a battery, charger, and inverter. Even at these prices, a single panel is unlikely to save you money over the electric company in the long run, unless your electricity is very expensive. There is economy of scale, so larger systems can and do save money, at least for people located in the right place. If you have a remote cabin where there is no electric company, then this could be worth it.
- Q: Can solar panels be installed on sports stadiums or arenas?
- Yes, solar panels can be installed on sports stadiums or arenas. In fact, many stadiums around the world have already adopted solar energy systems to generate electricity and reduce their carbon footprint. The large roof surfaces of these venues provide ample space for the installation of solar panels, allowing them to harness clean and renewable energy from the sun.
- Q: Can solar panels be installed on walls?
- Yes, solar panels can be installed on walls. Wall-mounted solar panels are known as solar wall systems, and they are a viable option for generating electricity from the sun. These panels are typically installed vertically on the sides of buildings or other structures, allowing for efficient use of space.
- Q: How do solar panels affect the overall energy consumption of a building?
- Solar panels can significantly reduce the overall energy consumption of a building by generating clean and renewable electricity. By harnessing the sun's energy, solar panels provide a source of power that displaces the need for fossil fuel-based electricity from the grid. This not only helps to lower energy bills but also reduces the building's carbon footprint, making it more sustainable and environmentally friendly.
- Q: please no dumb answers and list where you got the info.Also how much does it cost to install solar panels for a regular sized house?
- Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
- Q: I want to be more green and if I get the panels will I still have a regular electric bill?
- There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
- Q: i have 2 questions.. I have a 6v solar panel, if i wanted to charge batteries with that it what batteries could i charge? Could charge normal AA batteries with it our do i need special batteries.2. I have a 6v solar panel that produces watt. I want to light a bulb with it but whenever i hook it up the solar panel won't light it up. I think the current of the solar panel is too low. How can i increase the current of the solar panel
- [] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.
- Q: I want to install solar panels in my roof and most installers don't recommend any particular brand. Do you have experience with any particular brand that has worked for you or anybody you know? Does the brand of the panel make a difference?
- Bp380j Bp 80w Solar Panel (brand 80w 2v Module) Bp380j Bp 80w Solar Panel (brand 80w 2v Module) Ventamatic Solar Panel 0 Watt, Model# VX SOLAR PANEL Ventamatic Solar Panel 0 Watt, Model# VX SOLAR PANEL Additional 0 Watt multi-crystal solar panel for use with Item#s 336620, 336622. ... 8 x 3, Works With: Solar Fans, Solar Panel Bushnell Trail Scout Pro Solar Panel Accessory 9750C Bushnell Trail Scout Pro Solar Panel Accessory 9750C PANEL (CLAM) $59.95 BH Photo-Video-Audio Note: This is just a partial list. However, a brand does not really matter for solar or wind power. Most of them comes after the testing done by the government. Also if you can find local electrician to suggest how to get second hand panels for your house would be even better...
- Q: Ok so i'm writing this research paper on why solar panels are the best way to quot;go greenquot;. I need at least 5-7 reasons why they are good. and a common counterargument that i could defend. I've already come up with incentives and efficiency but i need a few more Please help its very important and worth half my grade
- I'm a big fan of solar panels, and we even have an array on our house, but I would have a hard time supporting the thesis that solar panels are the best way to go green. Conservation and efficiency are. Using less is better than making more. If someone has the money for panels, but their house is poorly insulated, their money would be better spent on insulation. Pretty much anyone in the solar industry would agree. And solar hot water makes sense over a much wider geographical range than solar electric.
- Q: I am doing research for a project.Please reply soon! :)
- Photolvoltaic arry is the more technical name and the more accurate name for solar panels. Photo indicates light and voltaic indicates a voltage is produced.. Array is just a layout of these little light sensitive electricity generating panels. Actually Solar only idicates the SUN and not light in itself..
