Production description

A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. 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. 


Depending on construction, photovoltaic modules can produce electricity from a range of frequencies of light, but usually cannot cover the entire solar range (specifically, ultraviolet, infrared and low or diffused light). Hence, much of the incident sunlight energy is wasted by solar modules, and they can give far higher efficiencies if illuminated with monochromatic light. Therefore, another design concept is to split the light into different wavelength ranges and direct the beams onto different cells tuned to those ranges.[citation needed] This has been projected to be capable of raising efficiency by 50%. Scientists from Spectrolab, a subsidiary of Boeing, have reported development of multijunction solar cells with an efficiency of more than 40%, a new world record for solar photovoltaic cells.[2] The Spectrolab scientists also predict that concentrator solar cells could achieve efficiencies of more than 45% or even 50% in the future, with theoretical efficiencies being about 58% in cells with more than three junctions.

Q: In terms of efficiency and cost, what is the best solar panel. I am limited in the number of panels I can put up (probably 6-8) so they must be efficient, but cost is important also.What about these panels that can collect a wider range of light frequency?
You have to decide which is more important to you, cost or efficiency. The most efficient solar panels that are commercially available cost more than twice as much per square foot than the cheapest ones. Ultimately, I believe that the cost per watt was actually better on the cheaper, least efficient panels, but then you need a lot of square footage in order to generate any substantial power. So it comes down to what you have more of, space or money. The new panels that collect a wider range of light are not currently available commercially, and when they are I am sure that they will be expensive. I have read the research but have not heard of anyone mass producing them yet.
Q: Can solar panels be installed on walls?
Yes, solar panels can be installed on walls. While they are commonly mounted on rooftops for optimal sun exposure, they can also be installed on walls using specialized mounting systems. Wall-mounted solar panels are a viable option for locations with limited roof space or where the roof is not suitable for installation.
Q: How do solar panels affect the electrical grid?
Solar panels can have both positive and negative effects on the electrical grid. On the positive side, solar panels generate clean and renewable energy, which reduces the reliance on fossil fuels and decreases greenhouse gas emissions. Additionally, solar panels can help decentralize the grid by allowing individual households or buildings to generate their own electricity, reducing strain on the overall grid. However, the intermittent nature of solar power can pose challenges for grid operators, as it requires careful management to balance supply and demand. Moreover, the increased number of solar installations can also lead to voltage fluctuations and grid instability if not properly managed. Overall, while solar panels offer numerous benefits, their integration into the electrical grid requires careful planning and coordination.
Q: I jotted down some notes for my Technology and Architecture class and I'm trying to figure out what i meant when i said 'Treated with gases at extremely high temperatures.' I have NO idea what I was talking about :) Im trying to figure out if what I am talking about is about Silicon, Polychristaline, or a Solar Cell/Panel.
Let’s start off and discuss the three main types of photovoltaic (PV) panels: Monocrystalline Solar Panels - Monocrystalline cells are cut from a block of silicon that has been grown from a single crystal.These tend to be the most efficient, but also the most expensive solar panels. They have been considered the go-to panels for the last couple decades, and also boast being the oldest and most dependable. Polycrystalline Solar Panels - Polycrystalline cells are cut from multifaceted silicon crystal. They don’t come from a single piece of silicon crystal, but rather from many different crystals. These solar panels tend to be less efficient than monocrystalline solar panels of the same size. This means a 200 Watt Monocrystalline panel will usually be smaller than a 200 Watt Polycrystalline panel. Thin Film or Amorphous Solar Panels - These panels are not made up of any crystals. They are actually a thin layer of silicon deposited on a substrate or base material like metal or glass. Thin film solar panels tend to be the least efficient per square foot, but they are also the cheapest. The best application for amorphous panels is if you have a large amount of surface area and space doesn’t matter.
Q: When I make a solar panel, what do I use to store the energy. For example I am going to make a solar panel to power my lights in my room. But I dont want the lights only to come on when the sun is out because that would be very pointless. So... Do I use the panels to charge something like a car battery and then run wires from the battery to an extension chord which will go to a surge protector? It sounds awesome, but I have to put it all together. The help is very appreciated. Thank you guys.
Let us know when and where you'll try to make your solar panels so that we can enjoy the fireworks from a safe distance.
Q: I need a new roof soon and I was wondering what the difference in cost would be from a standard shingle roof to a roof including solar panels. Does anyone know the cost difference?
The solar panels are very expensive to provide much power. If u go that way do not skimp on the support as a high wind will blow them away. In Ecuador I put in a remote site for communications. It was working good when a Strong wind blew $0.000 worth of solar panels all over the jungle.
Q: Are solar panels worth the investment?
Yes, solar panels are worth the investment. They not only help reduce electricity bills, but also provide a clean and renewable source of energy. Additionally, they can increase the value of a property and contribute to a greener and more sustainable future.
Q: Just wondering if it is possible to recycle solar panels and where that would be done. If it is possible, is there a money refund in return. Or would it be better to just take the metal off and get a refund in that way? Looking for basically any answer here.
It looks like you can. Although, I haven't been able to find like a drop off location or anything like that. Here's two phone numbers if you want to ask them. It's Sunday, and I'm assuming they're closed, otherwise I'd just call for you. San Diego (69) 562-783 or Berkeley (50) 843-3. It's a company called Borrego Solar. They look like a BIG solar company that specializes in commercial, residential and public sector turnkey, grid–connected solar electric systems. With over 25 years of experience. They sound like they would know about recycling, and at least be able to give you more information. I think because it's such a specialized item that is being recycled, there aren't going to be many options/drop off locations. Which ever option you choose (disassemble, or recycle as a whole) might depend on if you're looking to save the environment or make a buck. I got some information from the first link below, and the second link is to that Borrego company.
Q: For those solar panels that you install on your rooftops, do they generate electricity when it's cloudy? And if yes, how much electricity does it generate compared to sunny days? For example...like only 25% electricity generated compared to sunny days?
No, silicon photovoltaics reacts to a very specific frequency of infrared light which matches the bandgap energy of it's outer electron shell. This frequency is reflected by clouds. However, thermal solar collectors such as evacuated tube collectors can function under cloudy skies albeit at a lower rate and there is at least one hybrid photovoltaic and thermal panel designed to take advantage of this.
Q: Are you a Solar Panel Specialist/Genius/Enthusiast?
Yes and No. I'm hardly a 'genius' or 'specialist' but I have built a couple solar panels on my own. They're actually pretty easy to construct and you can find all of the materials at your local hardware store. Each panel cost me about $60 to make. Solar technology is jumping by leaps and bounds, becoming more and more efficient :photo voltaic cells, for example. Solar energy is a viable energy source, that's for certain.
