Solar Module Introduction

Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells. These early solar modules were first used in space in 1958.

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.

Q:would a lazier work on a solar panel?
If you mean a LASER pointer, then the answer is YES. However, the light is concentrated on a very tiny spot, so the panel will NOT generate much. Laser pointers are rated in milliwatts. A typical red laser pointer is rated at maybe 3 milliwatts. So, that is all that will be transferred at MOST. You don't get something for nothing, so the panel MAY put out 3 milliwatts from the laser pointer, but probably less since the solar panel is not 00% efficient. Solar electrical panels rely on sunlight over a large area measured in terms of many square FEET of area. As for driving lamps, the lamps do not care where the power comes from, only that the voltage and current are correct. Most bulbs will work equally well on AC or DC. Solar panels are used to charge batteries, and the batteries are used with an inverter to supply 0 VAC to things like appliances. What you CAN do is use a laser pointer to turn off a photoelectrically controlled light, such as a streetlight, maybe. Many streetlights have a photocell on top which looks at the sky and turns on the light when it is near dark until shortly after dawn. If you can shine a laser on the dome of the photocell, it MAY be bright enough to fool the photocell into thinking it is daylight and turn the streetlight off for a while...
Q:Why should I use a Charge Controller for my Battery and Solar Panel based on these provided details?
Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
Q:How much should a 00 watt solar panel cost?
On OKorder, they seem to be priced around $400. You do realize it takes more than just the panels...
Q:Any companies that have solar panels?
Yes there are companies that sell solar panels, many of them specialize in solar, a simple google search with your state or city name and the word solar should get you many results. There are actually two kinds of solar panels that get installed on homes, one kind creates electricity, the other heats up water. Depending on how large a system you installed, you could have all of your electricity or hot water powered by solar, which would mean you'd use less nonrenewable resources like coal, oil, or natural gas. The other difference the solar panels would make would be in your electric or gas bill, that number would go down right away, but you'd have to wait a few years before the money you save there would cover the cost of buying the panels, the number of years depends on your state, and the size of your system. Starting in January there will be a 30% federal tax credit, that would mean savings for every installation in the US. Also a lot of states now have a rebate program, which means the system is even less expensive.
Q:What do I need to install a 40 watt solar panel?
There okorder.com/ Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:A question about Solar Panels?
Take a look on OKorder at some of the books on how to design solar energy systems. It is a bit more complicated than you might expect. I'm not sure what you consider to be a standard solar panel, but the 3' ones I have produce about 5 watts of power in full sunlight. Put simply, you need to convert the power from the solar cells (variable voltage) into a constant voltage usable for charging a batteries. Most of the low cost modules for this purpose can't handle more than about 00 watts. Larger systems are available that handle thousands of watts but they are quite pricey. Since you can't take out more than you put into your battery system, you can calculate about how long you can run a high-current appliance based upon its wattage rating, that of the battery system (adjusted for loss of converting to AC), and the charging system.
Q:How would you connect a solar panel to a fan?
Panels are rated nominally, and you can look at your fan to see what the ratings for the fam are to determine sizing of the panel. Current multiplied by the volts (rated) gives you the wattage of the motor- just use this as a guide for sizing the panel. You do want a little more power from the panel than the motor draws for purposes of starting the motor and for having the fan operate at lower sun angles as well. You can add a battery if you chose, but it is not a requirement. Just treat the leads of the panel like those of a battery red (+) and black (-) just connect those to the fan, if you match color for color, no problem. If the markings are not present and no wires are on the fan, try it one way, if it is the wrong way- reverse them. AC operated fans will require an inverter to convert the DC to AC. These draw a certain amount of power as well. In general the same rules of thumb apply. It is just easier though to stick with a DC motor.
Q:Can I install solar panel straight to battery on my truck?
If you were going to do that it would have to be the right size solar panel and you would need a solar battery charger so it doesn't fry your car battery
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!
