Q: I am searching for producers or distributors of solar panels. Thanks!: There are ton's of distributor around that can provide you a cheap solar panel that didn't came from China.

Q: I am interested in installing a home solar panel system. In my city, we get a little over 5 hours of sun, and I typically use about 800-900 kwh per month.The available roof space is small- approximately 600 sqft.The online calculators provided on various sites are not uniform, thus providing inconsistent responses with the same input data.I think I need a 5kw system approximately. Can anyone verify that and provide a link for a reasonably priced system to meet my needs? Prefer grid-tied, but off-grid is acceptable as well.Thanks!: I'm sure that you will discover everything related solar energy at www.okorder .

Q: What is the biggest solar panel you can buy?How much energy can it produce in kwh?Thanks :): come to tn

Q: Hi All,I need some resources for a research project i'm doing on Solar Panels/Cells.So do you know of any good books or online materials that basically covers how solar cellwork from level 0 to calculating the energy output based on intensity of the light and the area of the panel. Book titles will be preferable but i'd like to build a strong base before tackling long and complicated formula(s)... so any suggestions? Your help will be appreciated :)THANKS IN ADVANCE!!: My guess is that you must pick up everything that have to do with solar power at www.okorder .

Q: I've run out of things to keep me entertained recently and as part of a larger project, I was curious if its possible to 'McGuyver' up a solar panel out of common materials?: Building your own panels can be an interesting experiment, but if you are looking for solar panels to provide significant, consistent output, you should buy factory made ones. I get lots of calls from people who built their own panels and get a fraction of the advertised output from them. Plus, factory built panels will last 40 - 50 years, with a 25 year warranty, how sure are you that you can build something that can withstand the outdoors for that long? The price of panels has dropped a lot this year, plus with rebates and tax credits, it's getting more affordable.

Q: How Much energy does Solar Panel Produce,and How long can Solar Panels go without maintenance.: Solar panels come in many kinds, using a variety of technologies and sizes, but the most common is still the crystalline silicon type. The power produced is variable, but the better ones you can buy approach 20% efficiency, and the peak energy from the sun is 200W/m^2 (Watts per square meter). This only occurs when the panel is lined up with the sun on a clear day with the sun high in the sky. The efficiency is also affected by how the electrical energy is taken from the panel, and the temperature of the panel. In the full sun the temperature approaches 60C, so the voltage drops. The links below provide a lot of information about such matters. A BP panel 50mm x 674mm gives a peak power of 20W. This is .07 square meters. As you can see this is very close to 20%. (The third link). However this is less in practice because the sun may not be full sun and may not be perpendicular to the panel. The output drops as the cosine of the angle to the sun, more or less. Even with peak sun this would produce only about 00W charging a 2V battery directly, unless an electronic Maximum Power Point Tracking (MPPT) charge control is used.

Q: i need to make a mini-solar car which shouldn't cost much. it's for my science project. for now, i just found out how to make a solar panel using copper oxide, but it does not generate enough power to power up the engine of the toy car [ the small engine they used in the toys, like from TAMIA]: There are several types of solar panels. If you mean photovoltaic panels for generating electricity, that is a really advanced project that few amateurs are equipped to do. In the long run, it will be a lot cheaper and easier to buy factory made PV panels. You can try building one by sandwiching an array of photovoltaic cells between a sheet of glass or plexiglass and a sheet of aluminum. Remember that this assembly must be able to withstand great heat, and it must be sealed to make absolutely sure it does not leak.

Q: Aren't batteries bad for the environment?Toxic?Expensive? With small solar panels phones, iPod's, laptops other small electronics could be smaller, slimmer, more efficient cost people less to charge every day. Maybe a small battery inside as a backup and to store the Solar energy for night time. But overall, batteries should be optional. So big question:Why aren't electronics being produced with solar panels?: Solar panels could still be expensive, which would also raise the cost of the item.They also are made with chemicals that harm that enviroment(not too badly, but ya know..) You would also need to charge them, of course, in sunlight and most people enjoy the benefit being able to plug something in and still being able to use it. Not saying it's a bad idea, just the world we live in.

Q: Can solar panels be used to power a construction site?: Yes, solar panels can be used to power a construction site. They can provide a clean and renewable source of energy to run the equipment and machinery needed for construction activities. By utilizing solar power, construction sites can reduce their reliance on fossil fuels and lower their carbon footprint.

Q: I got a really great deal on 2 houses because they were fixer-uppers. I'm living in one and the other I'm renting out. However, the previous owner did everything himself in 950 95, so needless to say, things are not to todays standards. Both houses need rewiring (there are no ceiling lights, few outlets, and mine has two old fuse boxes and the other has a breaker box but it pops the breaker a lot). The only reason they are still functional is because both houses use natural gas for water and heat, so otherwise, they electrical work is getting us by, but who knows for how long. I thought that maybe instead of redoing the electric, that I could just add solar panels to compensate for the small electric boxes. Also, since I would have to hire electricians to do all the work, which would be more cost effective (not including the decrease in utilities since I don't pay the utilities in the rental anyways)?: A solar panel does not replace the wiring in your house. All it does is supply power to the house, the same way a line in from the street does. After the power gets to the house, regardless of how it got to your house, it goes through exactly the same wiring to get to outlets and lights. Your problem is not that the power coming in from the street is insufficient; the power company can supply all you'd ever need. The problem is that your houses are not wired to receive or use more power. You need to upgrade the service panel so it can bring more power into the house, and upgrade the wiring inside the walls so you have the number of outlets and lights required by today's codes and which most of us need for all the things we plug in these days. Solar panels, while they are cheaper than ever, are not a low cost thing to install. It will take years to recover their cost, and if the rules are the same where you are as they are here, you can't use the cost of installing them as a write-off against the cost of the house until you sell it. They are a capital expense, not a maintenance and repair deduction which you can use each year against the income you receive from the rental. Doing a conventional rewiring is your best bet.
