- Q: What do I need to use this as a battery charger
- I hope this will help you choose your charge controller / battery charger more effectively. Good luck!
- Q: I don't know anything about where to buy solar panels. I just want to save on the electric bills.
- Solar panels could supply an air conditioning unit but it would be SUPER expensive to do. Air conditioners are power hogs.
- Q: Can solar panels be installed on residential complexes or apartment buildings?
- Yes, solar panels can be installed on residential complexes or apartment buildings. Many residential complexes and apartment buildings have successfully installed solar panels to generate clean and renewable energy for their residents. This not only helps in reducing electricity bills but also contributes to a greener and more sustainable environment.
- 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: Does a solar panel work under a full moon a tiny bit, or not at all? Likewise, if you used mirrors or lenses the concentrate sunlight, is there a maximum to how much a solar panel can handle?
- Under a full moon your solar panels can put out full rated voltage but no amperage. You do not want to put mirrors on your solar modules because you will just simply burn them out. They are made to use what the sun puts out and the extra heat from the mirrors would be too much. Plus you would have to build something to make the mirrors follow the sun or the reflected light would be moving on you all day as the sun moves. If you was to take apart one of those mirror balls that you see on dance floors and put all the little pieces on a board at angles to all aim at one spot. you would have a lasor beam of a sort. You can melt steal like that. Think what that would do to your solar panels.
- Q: Solar panels are all divided into these squares, forming a grid like pattern. Is it possible to have a single piece of solar panel?
- Yeah, but if something happened to it you would have to replace the whole thing. This way you only need to replace a small bit of it if there's a problem. Plus, they're easier to transport.
- Q: Solar Panels not working very well, they have faded. Is there any paint or anything else I can do to restore them? Thanks Eileen
- Unfortunately Eileen the panels are bound to fade as its par for the course. Over time much like everything else (from an AC condenser to your knees and hips) everything starts to go south. When did you purchase and install your panels? If this was done within the past few years then something is definitely wrong, and you should have the manufacturer and installer come back and replace the panels....on their dime of course. Is the warranty on your panels still in effect? If so then its definitely something that they have to come back and take care of. There is a company I know of called Sun Electronics that has a 20 year warranty on their products, so if its worth anything you might want to buy your new panels/system from them. The panels around today are more efficient than those of years past, and with the cost coming down due to economies of scale and the tax incentives you might want to consider getting a new system. Sorry to let you down though Eileen!
- Q: Got a small project here in a remote location. There is to be a 2 volt deep cycle battery, the equipment to be powered from battery and solar panel to charge battery. The 2 volt battery puts out 55 AH. the max constant power draw from the equipment to be powered is 7.9 watts. Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight?And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge?Thanks to all the input!
- Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight? Maybe theoretically, but you're going to have very little margin for losses and clouds. I'll bet it has very little power when cloudy. 7.9/30 = 0.26. So at 00% efficiency, you'd need it to be charging more than 25% of each 24 hour period. In a summer with long days and a climate with few clouds, you might make it. But I think you're very close to the edge. And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge? For an ideal battery: time = Q V / P time = 55 A h * 2V / 7.9W time = 83 hours So you've got pretty good margin on your battery.
- Q: I am doing a big project for school, and I have decided to do it on solar panels. I am new to the subject but have done some research on it; I would like to buy a single panel, a charge controller, an inverter and a battery, to charge a simple lamp. My question is if the items in the links will work together and if the panel will produce electricity?
- go with a 2 volt dc lamp bulb [auto lamp] then you wont need the inverter, all solar panels produce dc current
- Q: Are there any risks of fire associated with solar panels?
- Yes, there are some risks of fire associated with solar panels. While solar panels themselves do not combust, there have been instances where electrical malfunctions, such as faulty wiring or improper installation, have led to fires. Additionally, if a fire breaks out in the vicinity of solar panels, it can be more challenging for firefighters to extinguish due to the electric current flowing through the panels. However, when installed and maintained properly, the risks of fire are relatively low.
