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: I'm thinking of these solar panels that people have on their rooftops in domestic properties. I suppose I mean after how long do you break even with respect to just carrying on without them and getting you electricity from the utilities companies? Or answer in any way you think is pertinent. The more info the better.
It's generally stated that it takes 0 years for them to pay for themselves. But the concept of paying for themselves is a primitive concept used by those who do not understand finances. You're still losing money when it pays for itself. A more appropriate analysis would be the Internal Rate of Return calculations, Excel makes this calculation easy. Overall,?solar power?is expensive power and works out about 38 cents per kwh ( proper economic estimates typically place it between 23 cents to 45 cents per kwh ). Some idiot here will insist solar doesn't cost that much per kwh, it does unless you're uneducated in finance. Note, it's also not clear if the energy produced by?solar panels?exceeds the energy required for their manufacture, delivery and installation. It takes a lot of energy to melt silicon and the costs triple if you try to recycle the toxic wastes which is why the panels are made where it's still possible to dispose of the toxic wastes. They could very well be causing more environmental damage then they save. With the Europeans what happens is the feed in tariffs makes the solar panels worthwhile. They still don't really pay for themselves but they allow you to take some of the tax money from your neighbors, a bit of an ethical dilemma really but ethics never stopped Europeans.
Q: Exactly How much power will this kit produce? for example. Will it only be able to power the 2 light throughout an entire day or would it be able to power a couple TV's with a couple lights. Or a Refrigerator? washer dryer? I'm just wondering exactly what it will be able to do and if it's worth paying $200 for if it'll only power two lights. Don't get me wrong, That's great and will make a difference but i'm looking for something that will make a little bit of a bigger difference. Would the 80 watt monocrystalline solar panel be much better? if so, what would it be able to power? double?
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: Can solar panels be used to power a farm?
Yes, solar panels can be used to power a farm. By harnessing the power of the sun, solar panels can generate electricity that can be used to run various farm operations such as irrigation systems, grain dryers, electric fencing, and even power agricultural machinery. This renewable energy source not only reduces reliance on fossil fuels but also helps farmers save on energy costs while promoting sustainability.
Q: Can solar panels be installed on a prison or correctional facility?
Yes, solar panels can be installed on a prison or correctional facility. Installing solar panels can help reduce the facility's reliance on traditional energy sources and lower its carbon footprint. Additionally, it can save money on electricity costs in the long run. However, there may be certain security considerations and regulations that need to be addressed to ensure the panels do not pose any risks or vulnerabilities.
Q: Can solar panels be installed on a car?
Yes, solar panels can be installed on cars. These panels can convert sunlight into electricity, which can then be used to power various components of a car, such as the battery, air conditioning, or even the motor. Solar panels on cars are a growing trend as they offer a sustainable and renewable energy source, reducing dependency on fossil fuels and lowering carbon emissions. However, the effectiveness of solar panels on cars may vary depending on factors such as the size of the panels, the amount of sunlight available, and the energy demands of the vehicle.
Q: I have 2 20 watt Solar panel. I have it hooked up to solar controller and batteries to inverter. Am trying to figure out how much watts am getting. I found the voltage but how do I find the amp reading on a mutimeter?
While you can measure voltage on a like without a load, the measure of amperage is more closely related to the amount of power that is being drawn. The amperage is measured with the meter in series (not parallel like voltage) with the load. What it ends up measuring is the load that is being drawn from the solar panel and not the potential of the panel.
Q: Can solar panels be installed on windows or glass surfaces?
Yes, solar panels can be installed on windows or glass surfaces. These solar panels are known as transparent or semi-transparent solar panels and are designed to allow light to pass through them while still generating electricity. They are commonly used in buildings where traditional solar panels may not be suitable or aesthetically pleasing.
Q: Can solar panels be installed on a community center or recreational facility?
Yes, solar panels can be installed on a community center or recreational facility. Solar panels can provide renewable energy for the building, reducing reliance on fossil fuels and lowering energy costs. Additionally, it can serve as an educational opportunity for the community to learn about sustainable energy practices.
Q: I am doing research for a project.Please reply soon! :)
Photolvoltaic arry is the more technical name and the more accurate name for solar panels. Photo indicates light and voltaic indicates a voltage is produced.. Array is just a layout of these little light sensitive electricity generating panels. Actually Solar only idicates the SUN and not light in itself..
Q: Do solar panels increase property value?
Yes, solar panels can increase property value. Studies have shown that homes with solar panels tend to sell for higher prices compared to similar homes without them. The energy cost savings, environmental benefits, and potential tax incentives associated with solar panels make them an attractive feature for potential buyers, ultimately boosting the property's value.
