Solar Module Introduction
Solar Module is the core part of solar PV power systems, also is the highest value part of it. The function of Solar Module is to convert the sun's radiation to electrical energy, or transfer it to battery and store in it, or to drive the load running.
The Product has been widely used in space and ground, it mainly used for power generation systems, charging systems, road lighting and traffic signs areas. It could offer a wide range of power and voltage, and with high conversion efficiency, and long service life.
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: Can solar panels be installed on an RV or camper?
- Yes, solar panels can be installed on an RV or camper. In fact, many people choose to install solar panels on their recreational vehicles to harness renewable energy and reduce reliance on traditional power sources while on the road. Solar panels can provide a sustainable and efficient way to charge batteries, power appliances, and even run electrical systems in an RV or camper.
- Q: when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?
- Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.
- Q: What Are Solar Panels Made Of?
- Silicon, simular to aluminum foil. When assembled correctly will produce electricity. This is a prosition process to construct. Check out DIY sites on the internet. I hope this was helpful?
- Q: Would like to know if the DIY Solar panel systems can be as efficient as a commercial grade panel.
- What kind of panel are you talking about? Solar thermal, as in for hot water/room heating? Or photovoltaic? In the end its a matter of how good your DIY skills are and from what level of DIY you are talking about. eg, if you are buying the panels and installing them yourself, then there should be no difference. If you are fabricating the panels then you better be good at what you do. Creating photovoltaic cells is not a simple task. Soldering purchased cells together to create panels is tricky as they are easily damaged. Efficiency should not be a problem, but finish might be as well as robustness. It would be safer to buy complete panels and just mount them yourself and set up the batteries ans switch gear. But use good gear and follow instructions very carefully. With thermal panels you might not get the same levels of efficiency by using cheaper materials, std glass instead of non reflective for instance, but if space is not an issue, then you can get more heat out by going bigger and still save overall.
- Q: I'm building a solar panel for the first time and have the tabbed solar cells. I put together 4 strings of 9 cells. And the cells are each 0.55V, 3.6A.Because I'm going to be using the panel indoors and leaning it up against a window pane, I put them in a 24x36 inch poster-size frame. The frame has a plexiglass cover and a thick cardboard backing. My question to you is this. Will the cardboard backing up against the metal underside (positive side) of the solar cells be ok? I don't know if it may catch fire or if holes may burn through when there's full sun.My guess here is it should be ok. But maybe I'm wrong. If I am wrong, or if something should be put in between, please let me know what I should use.Thanks everyone!
- In commercial panels some sort of polymer is often used for backing. With a 2V panel there are 36 cells, which means they can still output about 4V for charging a 2V battery even when hot. The voltage reduces about 2.2mV per degree C per cell. Commercial panels are meant to work up to about 60 degrees C, which is quite normal in the sun. I have found just lying them on the grass the air circulation is reduced, and they get too hot to charge a 2V battery. This means the backing should have good thermal conductivity while being an electrical insulator, as well as mechanical strength. The cells are often encapsulated in a thermosetting plastic first, then laid face down so a liquid polymer can be poured as backing.. I have removed commercial panels from their frames and re-packaged them to work in a very wet environment. I suppose cardboard would work, but it is unlikely to have good cooling so the expected voltage would be lower. As you intend to only operate indoors I suppose it is unlikely you have full sun most of the time anyway, so there could be less heating and less output current accordingly. I think the cardboard is only useful for a short time, and is not strong enough. Temperature wise it is marginal. The link below uses plywood for the backing. The backing is supposed to provide strength too. A sheet of some sort of plastic or laminate (including melamine laminate as in kitchen bench tops) comes to mind too. The cells are supposed to be bonded to the backing for better thermal conductivity. Use silicon RTV to stick cells to the backing, very thinly.
- Q: If I wanted to put some solar panels on my roof, how many would i need and how many watts would they have to be to be able to power my whole house?
- Well, the best way to buy solar panels is to shop by watts. Solar panels come in a wide variety of watts, from to over 200. However, the more watts a panel has, the more it costs. I would suggest getting small things first, and gradually converting to solar power so as to help the environment and save money. If you have an outdoor pool, buy a solar collector to heat it. It will extend your swimming season and once you hook it up, you won't have to worry about it. (My cousins have this on their pool.) Also, there are solar cell phone chargers available for purchase, you could get one of those. As for your house, you would need several solar panels and a converter to be able to power your whole house on solar energy.
- Q: Ok, so I've been having much success with the joule thief circuit and a LED, but i tried hooking it up to a small solar panel that can put out 2.5v on it's own, and can light up a white LED dimly by it self to the joule thief and it will not work ....my question is why? I already trouble shooted it, the circuit is not the problem, is it the amount of amps the small solar panel is capable of? not enough?
- Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
- Q: I don't know anything about solar and what connections that have to be made. any advice and wisdom would be appreciated. thanks
- Solar Power For Laptop
- Q: Is it as simple as buying the panels, an inverter and plugging it into a wall-socket, assuming it would just send power back into the outlet and supplement my house's electrical usage, or... Is it not that simple?Remember, I'm talking about a SMALL system, and I don't care how little power it'd make, or how uneconomical it would be.
- For one thing, you would be trying to supplement the entire electrical grid. Same reason you must have a cut out relay for an emergency generator. Cause without one, you generator would be trying to power the whole regions electrical system. You could set up a solar system to just power specific things, like a gate opener, etc. But thy would have to be wired separate from the house a.c. electrical system.
- Q: Home depot has solar panels but they are so expensive? were is the best place to get them?
- Best okorder /... Of course sometimes you can get very cheap solar panels if you are in the right place at the right time... A friend of mine got the solar array from one of the road service companies... it had some minor defect so they were replacing it and throwing away the defective one... it still put out a good bit of power and it was free for him... but that is all luck.
