SOLAR PANELS GOOD QUALITY AND LOW PRICE-20W

Q:Can solar panels be installed on a theme park or tourist attraction?: Yes, solar panels can be installed on a theme park or tourist attraction. In fact, many theme parks and tourist attractions around the world are adopting solar energy as a sustainable and cost-effective way to meet their power needs. Solar panels can be installed on rooftops, carports, or even as ground-mounted arrays in open spaces within the park, allowing these attractions to generate clean energy while reducing their carbon footprint.

Q:Hi, I bought 50 6X6 inch solar cells, I also bought a 40 amp diode, I still need to buy a battery, and inverter and a voltage controller, could you tell answer me the following questions:) I would like t build a small panel at first, (may be 0 X 0 inch), with that I would like (or at least to try) to power my laptop for the hole day, so I wont receive a very high amperage, yet, all the inverters I saw at e-bay are rated over 400 amp, if I buy a 400 amp inverter, can I use it with such a small amperage?2) what about buying a small car inverter, will it work?3) suggestion about the battery and the voltage controller will be kindly appreciated.Thanks: I have an inverter that I use in my vehicle. It is rated for 400 amps this is it's maximum capacity. I can use it for less. It converts 2V DC to 20V AC. So Thais is all I need and may be your cheapest option. If your panels are producing a lot of amperage you may need a regulator to stop charging when your battery is fully charged.

Q:Im looking at making a self build iPad solar panel charger, Is it possible to get a small solar panel, a battery to hold charge and then a USB output? nothing fancy, just power in and power out?: Yes you can. You would need to look up and see the voltage output by a USB port and the current rating. You should be able to find it on the web. I have found it in the past. Check several sites to make sure that you have the correct values. Then wire up the solar panels to get the correct voltage and current capabilities. You may need to learn how a LM7805 works and wire one of them up to the circuit if you can't wire the solar panels to get the correct voltage. Make sure that you protect the solar panels from the weather and have some kind of protection for your iPad so that it does not get rained on and ruined.

Q:Are there any noise or sound-related issues with solar panels?: No, solar panels do not produce any noise or sound-related issues as they convert sunlight into electricity silently.

Q:I have 2 solar panels one is 5 watts 2 volts .2 amps or -The other is 50 watts 2 volts 2.6 amps or-Can I ...and what is the best way to hook them togeather to increase my amps being put back to my battery ?? I would be hooking them up to a 7 amp 00 watt charge controllerThe panels are rated 2 volt but the specs say they will produce more whennot connected to charge controllerPlease advise and should I even bother with the smaller panel ?: The answer is that the two panels should be put in parallel. The voltage out will drop to the voltage of the lower panel, but you should get most of the power, if the panels aren't too badly mismatched. I would try to get a multimeter and try to measure the actual current coming out of the panels in full sun. Sometimes the specifications on these smaller panels are very optimistic. If the whole setup is putting out less than 2 amps, I'd say wire the whole thing straight to the battery - little chance of boiling the electrolyte at those currents.

Q:Can solar panels be installed on a church or religious building?: Yes, solar panels can be installed on a church or religious building. In fact, many religious institutions have embraced solar energy as a sustainable and environmentally friendly solution to meet their energy needs. Installing solar panels on these buildings not only helps them reduce their carbon footprint but also promotes a message of stewardship and responsibility towards the planet.

Q:I mean when light hits the solar panel where does the energy go and what does it become? Be specific.: In a photo-voltaic cell, the energy of the light knocks electrons loose within a semiconductor, causing electrical current to flow. see science.nasa /science-news/sci... Some other kinds of solar energy plants use lots of mirrors to focus sunlight and boil water to drive a steam turbine and generate electricity.

Q:I want to install a solar panel system and our power grid can't work in reverse(so it get its electricity from us). My question is how do you prevent electricity from our panel to go to the grid without disconnecting the grid? How can we also use the grid and the panel at the same time when the panel are not creating enough power?PS dont say ask an electrician: If you are grid-tied, then a standard solar electric system will always feed back into the grid if you are not utilizing more power in your home than is being generated by the solar panels and inverter system. It is possible that a grid isolation device designed to prevent direct back feeding is available, but haven't heard of one in common use. New laws in most areas of the US are now mandating that utilities allow grid-tied alternative energy systems. Double-check you local laws. Sometimes you can't take the utilities word for truth--most will automatically say 'no' and will only relent when you show up with the law in hand. Unfortunately, some utilities have figured out another way to shut down alternative energy pioneers--they demand multimillion dollar insurance policies covering damage that their equipment could sustain from your little PV system. Technically, they are still in compliance with the law, they just make it impossible for a homeowner to meet their requirements. If you are getting the runaround, go to your state representative for help. It's amazing how contrite those utility people can be when a state senator (or even US Senator) has just sent a letter asking them why they are stonewalling a law-abiding and well-meaning citizen. Good luck, and don't give up!

Q:Can solar panels be installed on restaurants or food establishments?: Yes, solar panels can be installed on restaurants or food establishments. In fact, many food establishments have started to embrace solar energy as a sustainable and cost-effective solution to power their operations. Installing solar panels on rooftops or in parking lots can help these establishments reduce their carbon footprint, lower energy costs, and demonstrate their commitment to environmental sustainability.

Q:My home uses an average of 2400 kW per month (28,800 per year.) How much can I expect it to cost to install solar panels of this amount? (It is not my intention to go off of the electric company's grid. I would like to generate what I can / possibly sell back extra power)What quot;hiddencosts are there? What is the average life of them?What is the quot;best(cost effective and green) solution / approach?(BTW.... I am in southern LA if that makes a difference)Best answer will go to clear answer WITH links/resources to back it up!)THANKS A MILLION!!! I hope you have a safe and happy holiday season!!!: solar panels are expensive and you probably wont life long enough to recup the cost. last week the times quoted ?5000 to install, a potential saving of ?200 per year and 00 years to recoup. based on 400 hrs of sunshine. (uk) factor in your sunshine state hrs and you may just benefit.
