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:Can solar panels be installed on universities or educational campuses?: Yes, solar panels can be installed on universities or educational campuses. In fact, many universities and educational institutions have already embraced solar energy and installed solar panels on their campuses. This helps them reduce their carbon footprint, save on electricity bills, and set an example for students and the community in adopting sustainable practices. Additionally, educational institutions often have ample roof space or open areas that are suitable for installing solar panels, making it a feasible and beneficial option for them.

Q:Can solar panels be used for powering Wi-Fi networks?: Yes, solar panels can be used to power Wi-Fi networks. Solar panels generate electricity from sunlight, which can be stored in batteries or directly used to power Wi-Fi routers and other network equipment. This allows for the creation of off-grid Wi-Fi networks in remote areas or during power outages, providing reliable and sustainable connectivity.

Q:There is a charge controller that has what i believe to be only port for a solar/ wind turbine control panel and i don't know if it has more than port for panels. So would i be abed to link 2 panels to port or do you think the controller has more than portBTW it is for marine use.: It will not hurt the panels to hook multiple ones in parallel (all red or positive wires together, and all black or negative wires together), and connect it to the single port on your charge controller. The more alike the two panels are, the better this will work. With two absolutely identical panels, you should get twice the power. With mismatched panels, somewhat less. This arrangement will not hurt the charge controller, either. The worst that happens is that the controller isn't able to take full advantage of all the power available. By the way, it's not advisable to connect both solar and wind together.

Q:Can solar panels be installed on bridges or highways?: Yes, solar panels can be installed on bridges or highways. This is known as solar roadways or solar bridges. These panels can generate electricity by harnessing sunlight and can be integrated into the surface of bridges or highways. However, the feasibility and practicality of such installations may vary depending on factors like structural considerations, cost, maintenance, and local regulations.

Q:If you were to be asked to write a material(s) report on either -solar panelsor -aircraft fuselageWhich would you choose?well i was asked to choose between these two,so i guess that if i choose what the majority wouldn't, i might just score a little bit higher,what do you think?if you are the lecturer you would want something different right?: Fuselage, solar panels are boring...check out the design considerations for the fuselage of the old SR-7 Blackbird, a really amazing aircraft in its day.

Q:I own a townhome in the Phoenix area (my power company's SRP, if that makes a difference). Phoenix is a great place for solar. I could probably save money, in the long term, if I got some solar panels.But I am currently extremely broke, so I can't buy solar panels unless I will more or less immediately be paying no more than I am now per month, with little or nothing down. And most of the solar leasing places won't work with me, because (as is common for townhomes) I don't technically own my roof. I have permission to put things on it, but the property management people (or whoever actually owns my roof) won't sign the lease or whatever.Anyone know of either a way to buy solar panels without paying significantly more per month than I already do for electricity, or a solar leasing company that can work with the restrictions I have?: There are companies who would install solar panels on your roof for no cost. The catch is that they get the power generated for the first 20 years which is the useful life of the panels then you get what's left of the obsolete panels, meanwhile you're required to purchase your power from them at allegedly reduced rates but there is no guarantee that they would remain reduced versus the market once they have you locked in. It's like how the cell phone companies will give you a free cell phone if you sign a contract. Keep in mind that once you've factored in the installation costs and the useful life of the panels, the effective costs of solar photovoltaic energy is about 23 cents to 43 cents a kwh while grid power is about 5 cents per kwh to the consumer, 3 cents per kwh to the utilities for coal generation. It's just that so few people understand how to project an initial capital expense with periodic future returns through discounted cash flow, hence people think solar power is free out of ignorance. Without government incentives, there are no economic benefits to solar and most solar installers structure the sales such that they gain the economic benefit instead of the consumer who is often ignorant of how to calculate the financials.

Q:Basically I need a custom solar panel created. I won't go into detail but the dimensions need to be around 4''x2.5'' and be as thin as possible.: There's no way that home built system that will generate enough power to run your home off the grid. That's all hogwash! No wind = no electricity generated. No sun = no electricity generated. I'm looking into a grid tie solar system. I'm still working out the math for my home. They are expensive ($20k - $50k) before tax credits, but they have been designed by engineers, not back yard, shade tree wanna-be engineers. They will put power into the grid during the day (making your meter run backwards) and you'll draw the power back at night (when there's no sun). This is perfectly legal. It must be installed by power company approved techs. That's how power companies are going to meet their green energy mandates for the future. You'll generate power for the power company and get paid wholesale prices for it (during the day). But you'll buy it back at retail (at night)

Q:how does solar panels work?: Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.

Q:i used 734 killowatts of power last month, any idea on how many solar panels i would need. What im looking for is to somehow hook up my central air to solar panels.: LOL!! There is a lot more to this than you might imagine. This is a very rough approximation but look at the attached and column labeled 6.3KW. Look down that column and you see where it says Est. First Year KWH Generated ,025. So if we were to assume that each month it will produce ,025/2 kwh. (not true for January but I am trying to keep this simple. The installed price without any rebates is $44,050. ;-) Sorry! You will find some a little cheaper... some a little more expensive but none are a LOT cheaper than this. (this price does not even include energy storage, so the sun goes down and you will stop producing electricity). This is why, when people start looking at this sort of thing, they always do what they can to conserve electricity first. It is always much cheaper to conserve, then worry about alternate energy.

Q:Can solar panels work at night?: No, solar panels cannot generate electricity at night as they rely on sunlight to produce power.
