Product Description of Polycrystalline Solar Panel

CNBM Solar Polycrystalline Series (25W—310W)

CNBM Solar photovoltaic (PV)module is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array.Poly- or multicrystalline silicon(poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified. Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient. US DOE data shows that there were a higher number of multicrystalline sales than monocrystalline silicon sales.

Q:Hi, I am starting to get curious about the pros/cons of installing solar panels - has anyone done it and is it worth it?: The trouble is that it is so expensive to have installed and as you say it will take many years before you actually start saving above what the installation cost was, I personally would not go ahead and make that sort of investment, it would be more profitable to keep the money in a building society, get the interest from it and use that to pay for your electricity but the main thing that I have against solar Panels is that unless you stay in that house for at least twenty five years you will not reach the point where you are saving and to capitalise on it you would have to stay there for many years more, so you will not have the option of moving house without losing your investment and at the moment having solar panels does not increase the value of the property, it is just a good selling point, when you buy your new house, you would probably have to start all over again and then because of the years will never live long enough to reap any benefit from it.

Q:i already have solar/gas water heating, but was wondering if getting solar panels for electricity installed was a good idea.: Definitely, your idea is a perfect one. Solar electricity panels work well.

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:Can solar panels be installed on historic buildings?: Yes, solar panels can be installed on historic buildings. However, the installation process needs to be carefully planned and executed to ensure that it does not damage the historic fabric or compromise the architectural integrity of the building.

Q:How do solar panels affect the roof's structure and integrity?: Solar panels can have some impact on the roof's structure and integrity, but they are designed to be lightweight and installed without compromising the roof's stability. Properly installed solar panels distribute the weight evenly, reducing the likelihood of any structural damage. Additionally, solar panels can help protect the roof by shielding it from the elements, potentially extending its lifespan. However, it is crucial to consult with a professional to ensure proper installation and minimize any potential impact on the roof.

Q:Can solar panels be installed on streetlights?: Yes, solar panels can be installed on streetlights. They provide a sustainable and cost-effective solution by harnessing the sun's energy to power streetlights, reducing the dependence on traditional electricity sources and lowering overall energy costs. Additionally, this renewable energy option helps to reduce carbon emissions and promote environmental sustainability.

Q:looking for a solar panel to charge my laptop on the road, macbook is 60 watt 6.v 3.5a, what should i be looking for in a solar panel?: an significant questions is what voltage output is the skill grant? what's the wattage while the laptop has been used for hours and then related to the charger with the computing device off? this often is the skill attracted to can charge the batteries. Your answer desires to be waiting to take action skill score. additionally thinking the fashion of Apple skill plug the relationship thoughts would be few. fold-able image voltaic panels + small 2 volt battery + inverter + Apple skill grant or fold-able image voltaic panels + DC to DC regulator for particular Apple computing device DC voltage which contains the recommendations-blowing plug and polarity. Can a internet-e book or pill or clever-telephone meet your vacationing computing desires? all of them use much less skill and could require much less image voltaic kit.

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:How much space do I need for solar panels?: The amount of space required for solar panels depends on various factors such as the size and type of panels, the efficiency of the panels, and the energy needs of your household or facility. On average, a 1 kW solar panel system typically requires around 100 square feet of space. However, it is best to consult with a solar installer or expert who can assess your specific requirements and provide accurate information regarding the space needed for solar panels.

Q:Can solar panels be used to power a skyscraper?: Yes, solar panels can be used to power a skyscraper. Advanced solar technologies and efficient panel setups can generate significant amounts of electricity, making it feasible to meet some or all of a skyscraper's power needs. However, considering the high energy demands of skyscrapers, a combination of solar power with other renewable sources or grid connection is often employed to ensure a reliable and consistent power supply.
