Structure
A PV module is a packaged, connected assembly of typically 6×10 solar cells. Solar PV panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 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. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

- Q: How will i construct solar panel?
- The first step to planning your system is to evaluate rebate options and obtain permits. Deciding the size of your system is the next step. With a grid-tied system, size is less critical, because the grid supplies power when your PV system falls short. Systems as small as a couple hundred watts are practical, but you can also install panels that will produce enough electricity for all your needs.
- Q: we are trying to reduce a solar panel from 9 volts to 3 volts. What do we need to make this work...
- Solar panels generate DC power. Changing DC voltage is hard, which is why the power grid is AC voltage. AC voltage can easily be changed with a transformer. To keep the DC power (watts) the same at a lower voltage you need a DC to DC converter. That basically changes the power to AC with an inverter, changes the AC voltage to the new value, then rectifies it back to DC. It is probably hard to find a commercial unit that handles those voltages and then it will be expensive. But I have a simple solution in the special case of a solar panel. Solar panels are made up of smaller solar cells. The basic solar cell has a very low voltage, like half a volt. The panel has many of them connected in series to make a higher voltage. Just cover (shade) some of them and the voltage generated by the panel will be less. Of course that reduces the power. And you may need to experiment with shading different parts of the panel and measuring the result with volt meter.
- Q: Can solar panels be installed on a telecommunications tower or antenna?
- Yes, solar panels can be installed on a telecommunications tower or antenna. In fact, many telecom companies are increasingly adopting this practice to power their equipment and reduce reliance on grid electricity. Solar panels can be mounted on the tower structure or integrated into the antenna design to generate renewable energy and ensure continuous power supply for telecommunication operations.
- Q: Can solar panels be installed on a carport structure?
- Yes, solar panels can be installed on a carport structure. In fact, carports are a popular location for solar panel installations as they provide ample space and can generate clean and renewable energy while providing shade and protection for vehicles.
- Q: Let's say I can buy solar panels for my business for $5,000 and my payback period is 8 years. Would it be correct to assume that my money is best spent elsewhere (such as paying down debt) if I am being charged an interest rate of 3.9%?
- Without doing any calculations, I would assume that paying down debt would be a better use of your money. Solar panels are only going to get less expensive and more efficient with time so waiting before you invest in solar panels is a good idea. Of course, to properly evaluate the prospects of going solar, you should consider the tax credits available in your state and the promotional value to your business.
- Q: I have a cabin in the woods and need more light. I do have enough sun but I was wondering how or where do I get a solar panel to lead to a power outlet? In a perfect world I would like to get a solar panel with a connecting wire to an outlet or something so I could power a small TV. I know its hard enough but can I get that pre-made? Or even lastly should I look at wind power consider I would like this to be under $500? Thank you for putting up with this bundle of questions.
- First okorder /
- Q: Is there a material that is capable of absorbing enough UV radiation to make it worth using as a flexible solar cell?Not flexible as in aluminum, but a material such as plastic (polycarbonate).
- They are working on printable flexible panels. So why stop with the roof? Many of the surfaces could be covered to take advantage of the sunlight no matter where it hits the jeep. However the actual power acquired would not make much of a difference while driving. It would allow the Jeep to charge back up while your out backpacking.
- Q: Are solar panels safe for the environment?
- Yes, solar panels are safe for the environment. They generate electricity using sunlight, which is a renewable and clean energy source. Solar panels produce no greenhouse gas emissions, air pollution, or waste materials during operation. Additionally, they do not deplete natural resources, as sunlight is an abundant and infinite source of energy.
- Q: Due to erratic power cuts in my area I want to make up by using a 30watt solar panel. My decoder is 30watt but my TV is 70W. I need something small. I don't have problem with sound. Just picture.
- Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
- Q: I am doing a school project and we need to find the cost of solar panels for our school. The problem is i don't know what size the system needs to be. Is it 000 watts or 000000 watts?Also can you find the cost of the system?Thanks
- Without them providing the amount of energy your school uses then it's impossible to know how many panels you would need. Just phrase it in the form of how much space or how many panels would be needed to create (X) amount of power. Ask the amount the school uses then go from there. Let's put it this way, with today's solar technology you would probably have to cover most of the roof of the school with solar panels and it still wouldn't be enough to run the school entirely. Never mind the cost of out-fitting a building of that size, it would take far to many years to pay off and would probably never offset the cost of electricity they are paying now considering maintenance, upkeep and replacement costs associated with these systems. If it was that easy and cost effective, they would have already done it. Make sure you squeeze that into your report somewhere. Find out how much electricity costs in your area, its on any electric bill, it should show the cost per Kw/h somewhere (If separated by peak time and non-peak time, your school would be peak time). After you get that and how much the school uses, do the math and include a graph comparison showing the cost of both. You should be able to find the costs of solar panels online somewhere. Do a side by side comparison from start up cost, upkeep and all versus using the current source. Good luck on your report.
