Q:solar panel design question?
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:I have a question about solar panels?
My mum has solar panels and her electricity is still on all the time. If she uses stuff during the day, it doesn't cost her anything, as the panels are generating electricity, but at night if she uses things, then it will cost her coz there's no sun and no electricity being generated. She's still connected to the grid to use electricity but because she's feeding the electricity produced by her solar panels back into the grid the company pays her a certain amount for the no. of Watts that's produced. They cost a lot to install, but as she is generating more than she's using (even taking night time into account) she is being paid more back. e.g. before panels she paid ~£30per month. Now she receives ~£70per month. so she's about £00 a month better off (coz she's saving the 30 AND being paid the 70 on top of that)! and will therefore gain the money back that she paid in in about 8 years or so. Hope that makes sense!
Q:Composition and function of solar panels
In addition to the quality of EVA itself, the components of the manufacturers of laminated technology is also very large, such as EVA glue degree is not up to standard, EVA and tempered glass, backplane bonding strength is not enough, will cause EVA early aging, affecting components
Q:Feedback on Solar Panels?
They work. If you have realistic expectations of them, understand their limitations and have a good knowkedge of electronics, you will be glad you have them, and you will also likely want to add more as you can afford them. If you need someone else to install them and you know little to nothing about electronics, your installation cost will be much higher. However they are not always a total solution, and for those wanting to continue using energy the way they do when attached to the grid they will be disappointed. You do need to make some changes to how you use energy. Get them for the right reasons, and at some point you can unplug your house from the gtid. Grid tir is fine for some, but highly overrated by those who wish to social engineer society to have things both ways- tied to the grid to produce power while letting the power company do it's thing to your appliances,
Q:Is there any way I can get solar panels with my restrictions?
Nope; I see no escape. Best advice I can give is this: sell out and move to a single home residence that has no HOA. If you want solar, I believe the main roofline should run east-west, so that the south exposure of the roof can be easily and economically populated with panels. APS is better than SRP wrt solar ....maybe. Im not sure, everythiong around here is APS so there's no balance. Ive occasionally heard rumors from SRP folks who are unhappy.... check into it before you buy.
Q:Will my off the shelf deep cycle battery I purchased at autozone work well with solar panels?
There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
Q:Can a solar panel be used as a NiCd cordless tool battery charger?
Two of those solar panels connected in series will easily charge a 8V battery. I would not even be concerned about over voltage the solar cells will have plenty of internal resistance.
Q:where to face solar panels?
Not compass south, but solar south. It's easy to find. Google Find Solar south and you can get directions. Even better are trackers, that will let your panels track the sun all day.
Q:How to install a solar panel system?
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!
