- Q: Can solar panels be installed on windows?
- Yes, solar panels can be installed on windows. There are specially designed solar window panels available that can be installed on the glass surface of windows to harness solar energy. These panels are transparent and allow light to pass through while generating electricity from the sunlight.
- 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: Can solar panels be used in commercial buildings?
- Yes, solar panels can be used in commercial buildings. Many businesses and organizations are incorporating solar panels into their buildings to reduce energy costs, decrease their carbon footprint, and take advantage of potential tax incentives or subsidies. Commercial buildings have ample roof space to accommodate solar panels, and with advancements in technology, solar panels can be integrated seamlessly into the building's design.
- Q: I contend:As far as the solar panels causing global warming I'll try to explain. If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). The net heat gain is zero. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The result is a net gain in earth's temperature.Right or wrong?
- One piece of technology: Hydro-energy storage. Pump water up to an artificial lake at the top of a mountain to store energy, and then let the water run down through turbines to retrieve the energy later, eliminating most or all of the need for batteries. Usually this stuff saying renewables suck is BS when you actually try. Yet another method, are solar power towers which last longer than solar panels and continue to generate energy at night. While a non-universal storage method, it's good for storing the sun's energy in the mechanism that generates the power. According to some studies, they are the best option next to wind turbines. I'll describe a particular model. A field of mirrors beams light to a part of the tower which contains salt, for it's incredible heat storage capacity when molten. In turn, the heat from that region heats water which spins some turbines, generating lots of energy. Currently, the best models continue to generate electricity at night and for a few consecutive cloudy days. I think whoever was saying that was probably trying to delay response. There are too many ways around that to be true, and saying that it contributes more to Global Warming than fossil fuels is a lie. This is why some government intervention is needed: The companies aren't responding to new ideas, and they happen to often be fossil fuel companies as well. If you don't create the environment where it lowers fossil fuel consumption, then they win because prices stay high.
- Q: i am looking for solar panels and wind mill to put around our house and i was wondering were to find them
- Your best bet would be to go down to a place that has magazines and look through their solar magazines, like Solar Today and Home Power. In these you'll will find many places online where you can buy solar and wind power products. They also have good reviews so that you can be an informed consumer and don't end up buying poor quality products. I've seen performance reviews on a variety of models.
- Q: What is the impact of roof age on solar panels' efficiency?
- The age of a roof can have a significant impact on the efficiency of solar panels. An older roof may have deteriorated shingles or structural issues that can affect the installation and performance of solar panels. Additionally, an older roof may require repair or replacement in the near future, which would require removing and reinstalling the solar panels, incurring additional costs and potential damage. Therefore, it is important to ensure that the roof is in good condition before installing solar panels to maximize their efficiency and longevity.
- Q: I am told there are night vision goggles to see at night due to invisible light still hitting earth. I am also told that there are other beams, x-rays etc hitting earth.Why couldn't they invent a solar panel with dual power in the day?It could harness both visible and invisible light, and at night be single?Anyone know why they can't make an invisible light solar panel?Is this possible?What happens if future cars have night vision windshields instead of lights?
- They are actually working on building photovoltaic panels (Photovoltaic is actually the correct term for sunlight--electricity. Ordinary solar panels are those that use sunlight to heat water) that harness a larger range of wavelengths. From what I can gather the problem is either finding a material that absorbs more wavelengths, or finding a way to get multiple materials to coexist in a single panel. This situation will no doubt improve over time as new things like Nanotechnology give us the ability to create much more complex substances designed at the molecular level for light capture. Panels that can harness a wider range of the spectrum do exist, but the technology is in its infancy, and therefore expensive and not widely known. This isn't too surprising when you consider that Photovoltaic technology itself hasn't been in the mainstream all that long. I am a bit doubtful of photovoltaics that work at night, for the simple reason that at night there is less of *every* kind of energy falling on earth. Less visible light, infrared, etc. Infrared just happens to be particularly good at giving away hot objects, which is how Night Vision goggles work. For the same reason, a night vision windshield might be a very useful tool, but it would still have difficulty picking out colder objects, and those that reflected less infrared light. In other words, you might see cars and pedestrians, but you could easily miss the upcoming embankment 0.o .
- Q: Can solar panels be used to power a restaurant?
- Yes, solar panels can be used to power a restaurant. Solar panels harness energy from the sun and convert it into electricity, which can be used to power various appliances and systems in a restaurant, including lighting, refrigeration, cooking equipment, and HVAC systems. By installing solar panels, restaurants can reduce their dependency on traditional energy sources, lower their electricity bills, and contribute to a cleaner and more sustainable environment.
- Q: How much does 000 square feet of solar panels cost? This is for a pool with dimensions 75ft by 25ft? How much will it cost including installation fee and the water heater?
- a clean insulating conceal may be lots extra decrease priced and doubtless do as lots sturdy as growing to be electrical energy to warmth the water. A green domicile over it ought to cost as much as panels, yet be lots extra useful.
