1. Structure of Polycrystalline Silicon Solar Modules 60Cell-245W Description

Solar panel refers either to a photovoltaics (PV) module, a solar hot water panel, or to a set of solar photovoltaics modules electrically

connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be

used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Each

module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a

module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16%

efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only

a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar

modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q: I need to use solar panels to charge lead acid batteries in an off-grid application. I understand that solar panels have a open circuit maximum voltage and an maximum amperage under no resistance, and that one can optimize the power output by regulating the load (resistance). If so, is just connecting 2 -volt solar panels to a lead-acid battery inefficient? Are there devices that will maximize 2 volt output power (by varying the resistance)? Am I on the right track here? Thanks for any help.: The answer is actually quite complicated, but if you're planning on building just a very small system, most likely, the panel will be small and weak. In this case, connecting a panel that is 8 volts open circuit directly to a lead-acid battery is probably the most efficient way to charge. There are charge controllers that you can buy, some of which actively track the maximum power point for charging your battery. Unfortunately, those controllers might eat 5 or 0 watts, just to get you another few percent of charging efficiency. If your panel is only 50 watts in the first place, you can see that this is not a good deal. If you're getting serious panels (clue: price $500 each), then you may very well benefit from a charge controller with MPPT (max power point tracking). Lead-acid, either a flooded cell like your car battery, or AGM, are the standard for solar energy storage. Lithium ion is better in many ways, being less sensitive to temperature, state of discharge, and they are also lighter. Charging them is also more straightforward with the right circuitry. The problem is, they cost like $500 per kWh, compared with less than a tenth that price for lead-acid.

Q: Can solar panels be installed in areas with high humidity?: Yes, solar panels can be installed in areas with high humidity. While humidity can slightly affect the efficiency of solar panels, it does not prevent their installation or operation. Modern solar panel technology is designed to withstand various environmental conditions, including high humidity, and they can still generate electricity even in humid environments.

Q: I have to get a lot of information on how solar panels are developed and distributed in America because I have to do two pages on this. Please help me get information in this I really need it!! Thankss...: The first link below is one of the best sites for recent news about solar panels. You should be able to find stories about solar panels under development today. A little bit of the history: Solar panels have been around for about 50 years now. They were first used to power spacecraft. Solar power for domestic use started to develop rapidly in the 970's during the first oil crisis, but as energy prices fell in the 980's solar development slowed. Most of the large solar panel makers were purchased by large oil companies who seemed not to be too interested in solar. In the late 990's as concerns about both Peak Oil and Global Warming grew there was renewed interest in solar power and a number of new companies were started to develop new kinds of solar panels. Many of these new companies have grown larger than the older solar companies still owned by big oil companies. Over the last 7 years or so growth in the solar market has been explosive with a compound growth rate of almost 40% per year. In 2005 the solar industry for the first time started to consume more silicon than all other electronic industries combined resulting in a world wide silicon shortage that is still with use. New silicon refineries are coming on line and the shortage is expected to diminish by 2008 or 2009. Check out the two links below. They will help you a lot.

Q: I thought they were going to make solar powered cars and solar power plants among other things. It was only nearly 0 years ago that solar power was the big thing. Just curious, why did it die out?: they still make them,i have them on my camper to charge the batteries, they are not cheap, however. you can get them at r.v. supply stores. in fact the ones they make now, are quite efficient, many people in the countryside use them for their homes, i dont know why the development for cars is so slow, though.

Q: Can solar panels be used for powering outdoor lighting?: Yes, solar panels can be used for powering outdoor lighting. Solar panels capture sunlight and convert it into electricity, which can then be stored in batteries. This stored energy can be used to power outdoor lighting fixtures, making them independent of the grid and environmentally friendly.

Q: By best I mean safest places. If I were to install them on my roof am I risking due to damage from weathering? Such as rain or snow. I don't get very high winds around here, nor any natural disasters such as hurricanes or tornadoes. Does anyone have solar panels that have been durable for a long time? Is it worth the investment?: Solar panels have to be installed so that they face the equator, so they would have to point south in the U.S.. There are panels designed for exterior mounting and panels designed to go behind glass walls, I've even seen some that are made to replace roof shingles. You'll have to determine if they are worth it or not. Most companies that manufacture the panels rate the output based on the area in which you live. If you live in the north, payback is usually over 20 years, closer to the equator the payoff is quicker, but still a while. The question of worth is relative: are you trying to save money or help save the world? Any alternative to hydro carbon is great for the environment, but most are still very expensive.

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!: o work out the wattage correctly, the panel needs to be sized according to how much power you are going to use. (Later on you're going to need a bit of info on each electrical item you need to be solar powered).

Q: Was looking at 0w solar panel kit. Does this mean, all I can use is something like a 0W CFL light bulb and nothing else?: No. The way to set it up is to store the power generated by the solar panel in a battery, then use the battery to power your lights, radio, etc, when you need the power. A standard deep-cycle marine battery is typical for panels of this size (WalMart for approx $90). A 0W panel will generate between 30 50 Watt-Hours of power over the course of a day (May-Aug weather-dependent), so this would equate to running a laptop for -2 hours, or a 0W CFL light for 3-5 hours, or a 20W stereo for .5-3 hours, etc. I find it is much easier to speak in terms of watts. Divide the watt-hours by the watts of the appliance to get the number of hours it can run. Hope that helps!

Q: How do solar panels perform in cloudy weather?: Solar panels do generate electricity even in cloudy weather, although their efficiency is reduced compared to sunny days.

Q: How do solar panels affect the roof's structural integrity?: Solar panels do not typically affect the roof's structural integrity. Properly installed solar panels distribute the weight evenly across the roof and are designed to be lightweight. In fact, they can even offer some protection to the roof by shielding it from the elements. However, it is important to have a professional assess the roof's condition before installation to ensure it can support the added weight.
