Q: Can solar panels be installed on a sports stadium or arena?
Yes, solar panels can be installed on a sports stadium or arena. Many stadiums and arenas around the world have already implemented solar panel systems to generate renewable energy and reduce their carbon footprint. The large roof space and open areas surrounding these venues make them ideal locations for solar panel installations. Additionally, the energy generated by these panels can be used to power the stadium's operations and even contribute to the local power grid.
Q: Can the solar panels available be coated with a material (to improve it's looks) and not alter it's efficiency?
No. The only coatings I am aware of are those that reduce reflection so more light gets through the protective surface to the actual cells. Anything thing that affects appearance is going to be reflecting light back to the viewer and the photons of that light are not available for electricity or heat. If the appearance of the panels offends you, then they need to be concealed by a fence of panels around them that do not throw shadows on the panels.
Q: Is there any way to charge my laptop with a solar panel? Is there any panel like that. Or if I work on panels can I do something like that. If you know anything about it, can you just help me? Thanks a lot.
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
Q: Hi. I have been looking into getting solar panals but I only want them for one room. See, we're expanding the house by adding a basement, the basement isn't going to be that big but we wanted to have solar energy for the basement only. Could anyone give me a rough estimate on the cost of solar panals for my basement?
As Tex said, you have no idea whats involved. Start by looking into some sites that explain how they work and whats involved before asking how much on a small room. And how do you add a basement but not a main floor? and where is the basement roof?
Q: What is the environmental impact of solar panels?
The environmental impact of solar panels is generally positive. Solar panels produce clean and renewable energy, reducing our reliance on fossil fuels and lowering greenhouse gas emissions. Additionally, solar energy production does not generate air or water pollution. However, the manufacturing and disposal processes of solar panels can have some environmental consequences, including the use of toxic materials and energy-intensive production. Nevertheless, the overall environmental benefits of solar energy outweigh these impacts.
Q: Solar panels would change the world if they were widely available to us especially cheap, it will be worth it in the long end. Money would be saved like housands a year per person on utility costs.
Down the drain. That money is gone. Just more wasted money the government writes off and then tries to raise taxes to pay for.
Q: Someone Said It costed them 50,000 To Install Solar Panel In their House and 35,000 For Installation. Is that true?
It depends on the number and size of the panels. The minimum charge for a small bungalow would be at least $20,000 labor and material.
Q: Do solar panels require direct sunlight to work?
No, solar panels do not require direct sunlight to work. They can still generate electricity from indirect sunlight or even on cloudy days.
Q: I need a list of worldwide solar panel manufactures from china, US, Spain, Germany, Japan etc...Can any one direct ne to such place?I rather it will also contain comparison of parameters like efficiacy, quality etc and to be divedied by country of manufacturing.Thank you
You can't buy at that level unless you are connected to governement. A lot of production is already spoken for for years to come. Where you live determines what you can legally buy and install. The EU has it's own certification, the US has 2 sets, the Canadians have their own. Your answer also requires knowing the use for the solar panels, whether it is grid-tie, off-grid or standalone to power an appliance. And you have to choose mono crystalline, poly crystalline, or thin-film.
Q: Can solar panels be installed on a museum or cultural institution?
Yes, solar panels can be installed on a museum or cultural institution. Many museums and cultural institutions have embraced solar energy as a sustainable and environmentally-friendly solution for their energy needs. Installing solar panels not only helps reduce their carbon footprint but also saves on electricity costs in the long run.
