CNBM Poly 245W Solar Panel with TUV UL CE Certificate For Residential 

Introduction

Electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive [transition metals]. The cells must be connected electrically to one another and to the rest of the system. Externally, popular terrestrial usage photovoltaic modules use MC3 (older) or MC4 connectors to facilitate easy weatherproof connections to the rest of the system.

Multiple solar cells in an integrated group, all oriented in one plane, constitute a solar photovoltaic panel or solar photovoltaic module. Photovoltaic modules often have a sheet of glass on the sun-facing side, allowing light to pass while protecting the semiconductor wafers. Solar cells are usually connected in series and parallel circuits or series in modules, creating an additive voltage. Connecting cells in parallel yields a higher current; however, problems such as shadow effects can shut down the weaker (less illuminated) parallel string

 Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 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, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Micro-inverted solar panels are wired in parallel which produces more output than normal panels which are wired in series with the output of the series determined by the lowest performing panel (this is known as the "Christmas light effect"). Micro-inverters work independently so each panel contributes its maximum possible output given the available sunlight.[6

Q: if you move a solar panel or there was a vibration that caused the panel to move, would that affect it?
No. I've got one on top of my RV and taking it down the road at 70mph doesn't hurt it at all.
Q: I know that one LED can't power a solar panel. I have found 40 kmcd LED's on OKorder. I know that several of them (28 totale each one with a 470 ohm resistor all at 2 VDC) can show a reflection on a wall in daylight 60 feet away..
Your question has a lot of science involved that I don't understand perhaps the link posted in my source for this answer could help you out? It a site containing only info on LED Lights. Good Luck
Q: I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.
Yes, you can purchase a solar photovoltaic array to keep your batteries charged. You will need a Photovoltaic Cell Panel that produces 27 + watts (6volts x 4.5 amps = 27 watts) at 6 volts of electricity, a Charge Controller that allows only 4.5 amps of power through to the battery and will reduce the amps as the battery nears full charge and shut off the Panel when the battery is fully charged, and a 6v. Battery. Figure you will need a photovoltaic panel capable of producing a minimum of 27 watts if you are going to charge a completely dead 6 v. battery in one day. (with a clear sky). The way the system works is the sunlight strikes the cells on the panel and releases the excess electrons in the cells, they travel along central wires to your battery and charge the battery. When the sun sets, the procedure is reversed and the electrons flow backwards from the battery, into the photovoltaic cells. That is where the Charge Controller is needed. It acts a one way gate and lets the electrons go into the battery, but won't let them go backwards to the Panel. Just set your panel in the sun at the optimum angle for the season and your latitude on earth, connect the charge controller and then the battery, and it will keep your battery charged. Don't waste your money on the small wattage solar photovoltaic systems that claim to keep your battery charged. They simply can't do it unless your battery is in like new condition and is fully charged when they are hooked up. If you battery is a few months old, the small wattage photovoltaic systems can't keep up with the loss of power from sulfation inside the battery.
Q: When you consider that solar panels will not produce enough electricity in their service life to cover their cost should we subsidize them anyway? that much of the cost of a solar panel is the energy to manufacture, install, transport and maintain them. Shouldn't the market determine whether they are worth installing?Is subsidizing them taking money away from research that could be spent on more viable alternatives?Should we be taxed to pay for others solar panels when they don't work?
Yes, okorder /... Bottom line is that government subsidies encourage people to buy solar panels, and make it possible for many who could otherwise not afford it. The more solar panels are purchased, the more the price will go down, and the more quickly the technology will be able to advance.
Q: am having a 75 watts siemens solar panel and is giving me 2.89volts during bright light, i wanted to know can this be used to charge 00Am/hr battery?
Many of the panels used on homes are designed to produce 2 volts DC. 0 of them wired in a series would produce 20 volts DC. An inverter is used to change the DC voltage to AC. The other aspect of electricity is amperage. With electrical units wired in series the voltage is added. When they are wired in parallel the amperage is added. The Volts x Amps produced will give you the wattage. A wise homeowner will examine their electric bills or the equipment used to determine their demand. They will consult tables that let them know how much sunlight their area receives each year as this will alter the rated performance of the panels. Then they will try and determine how much of the demand they want to fill. 80% may be economical. Then they also want to determine what they will do with excess electricity that may be produced during the summer months of intense sun and how they will supply the shortfall of low sun winter months. From all this they will determine the number of solar panels they need to purchase.
Q: I'm wondering if the cost of the panels and equipment have come down enough to make them viable in areas like Seattle or Vancuver for example.
The key is the average insolation value for the location. This is a number that represents the effective numbers of sunlight available per day. The insolation for Seattle varies from 2.9 and 3.57, depending on who is reporting the number. The insolation where I live, near San Francisco is 5. For me, solar is paying off.
Q: Can someone tell me the average savings you get PER solar panel installed? I do not have the money to invest in a bunch of them at once, so I am forced to buy one at a time, when I have the money. So how much can I expect to save after I buy the first one?
No matter what or how you do it it is best to get off coal and nukes. So it cost a little bit of money you are buying 30 years of electric. How much will you spend adding in cost of living increases over the next 30 years? Solar really is pretty cheap if you take the time to do the long term math. If you use your cost at to days rates it does seem like a lot. But if you do the math like in real life with 3.5% compounded cost of living increases per year and 6.5% fuel increases per year. Well, you pay a lot more renting power. One other thing to think about and Al Gore keeps pointing it out is, Will your off spring be alive in 50 years from now if you don't buy the solar panel? Kind of like not going to the doctor because you can't afford the bill. Well I would rather owe a bill to a doctor that I will have trouble paying then not be alive at all to try. If you don't have the money to jump in and go full blown Green you should buy a starter system. You can get a system that can be expanded to 3000 watts (enough to power an energy efficient home). Would cost you about $8000 USD to get started and then you could add three solar modules at a time till you get it up to the 3000 watt max. And even have backup power. Or you could just buy a 000 watt system for about the same price and just add 3 of them over the years. There are many ways to get started. The deal is everyone needs to get started even if it is a small system. If all 50 million homes in the USA would install a small 000 watt system with 4 hours of sun light a day. We would provide (000 watts times 4 hours times 365 days times 50 million homes) 29,000,000,000,000 watts not from coal or nuke plants per year. I wonder if that would help?
Q: Home depot has solar panels but they are so expensive? were is the best place to get them?
Depending on where you live, the combination of federal, state and city tax credits and rebates can offset the cost of solar panels substantially. Even so, unless you use a lot of electricity, it may take a few years for the panels to pay for themselves. You are essentially paying for your electricity in advance. The more you use and the more it costs per kW/hr, the quicker the cost will be offset by the savings. Don't install solar panels on a home you're renting or one that you will likely sell in the next few years. It's not practical to un-install them and move them to a new house. Energy conservation is the way to cut your enery bills with the lowest up front cost. If you haven't had an energy audit, see if your energy provider does them at low or no cost. Install timers on air conditioner thermostats. If you have electric water heating, have a timer installed on that as well. Water heating is one of the biggest energy wasters out there. Why keep the whole tank of water hot when you only use it in the morning to shower? If you have your heart set on having solar panels but can't afford the upfront cost, research the companies that do installations in your area. Some have lease and lease/purchase options now.
Q: I just connected my 5 Watt 2V solar panel directly to my 300 Watt 2 inverter. It worked for about 2 minutes then it popped (sparks, smoke etc)! What the hell did I do wrong? I thought the solar panel was 2 volts? Can someone with experience with these things help me out?
An 300W inverter will draw 25 amps from a car battery but the solar panel will only produce about 4 amps. By drawing too much power with the inverter you lowered the voltage so much in the panels wiring that the amp rating on the internal wiring was exceeded and they melted. Next, time run the panel to a voltage regulator, then the regulator to a car battery, then the battery to the inverter.
Q: That one costs money but looks like it might work. I don't really have the money for it but if it works then it would probably be worth it. Do homemade solar panels really work or is it just a gimmick? I'm really interested to see if anyone has actually tried this and to see what they say about it.Thanks
Solar photovoltaic cells oxidize, commercial panels are hermetically sealed but DIY panels degrade rapidly with time. Sizing the broken solar cells by individual measurements are labor intensive and the additional soldering makes them unreliable. Also, their irregular shapes result in less of the panel's surface area being covered with cells. They do work but not well and they deteriorate quickly.
