- Q:Can solar panels be installed on a concert venue or entertainment facility?
- Yes, solar panels can be installed on a concert venue or entertainment facility. Solar panels can be mounted on rooftops, parking lots, or even integrated into the design of the venue itself. These installations can help offset the energy consumption of the facility, reduce carbon emissions, and potentially save on electricity costs in the long run.
- 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:Can solar panels work in cloudy weather?
- Yes, solar panels can still work in cloudy weather, although their energy production may be reduced. Cloud cover reduces the amount of sunlight reaching the panels, resulting in a lower output. However, modern solar panels are designed to generate electricity even in low-light conditions, making them still effective in producing energy during cloudy days.
- Q:Could you have a solar panel in space that would transmit electricity remotely? Maybe have some kind of receiving antenna to pick up the energy? Perhaps there could be a string of them orbiting the Earth?Why wouldn't that work?
- Absolutely. Many satellites and other spacecraft that have been launched throughout history carry solar panels to power themselves. The International Space Station alone has hundreds of square meters of solar panels. Transmitting the power from one place to another wirelessly is a bit more difficult, but not fundamentally impossible. So far we don't have any good technology to do it over long distances. But we're getting there. One proposed future source of power is 'solar power satellites', orbiting devices that would collect sunlight and turn it into a microwave laser that would be fired down to the Earth and collected in a giant dish kind of like a radio telescope. The idea is that this would be non-polluting, environmentally friendly, reliable, would help to boost investment in space technologies, and wouldn't take up the large amounts of land area required for traditional solar power. However, some people have argued that it is a bad idea on the basis that if the laser accidentally missed the dish, and came down in an inhabited area, it might cause human fatalities or damage to the environment or human artifacts.
- Q:I want to be more green and if I get the panels will I still have a regular electric bill?
- The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array isn't producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. The best thing is to contact a professional installer to get a quote based on your location and electrical usage. Solar electric does not make financial sense in all areas. Our array cost $2,000 but don't use that as a guide. Yours might be 0 times that, or half that, depending on your area and needs.
- Q:Can solar panels be used for large-scale power generation?
- Yes, solar panels can definitely be used for large-scale power generation. As technology has advanced, the efficiency and capacity of solar panels have greatly improved, making them a viable option for generating significant amounts of electricity. In fact, many countries and companies are already utilizing solar farms and large-scale installations to harness the power of the sun and contribute to their energy needs.
- Q:How long does it take a 5 watt, 2 volt solar panel to charge a 2 volt R.V. battery?
- depends on the sunlight. And on the size of the battery. But it may never charge, as you need at least 5 volts to charge a 2 volt battery. So unless the sunlight is bright enough to generate 5 volts, all you will do is discharge the battery through the solar panel. But a large battery is 00 amp hours of capacity. Even if you had a 5 volt 5 watt panel, that generates only amp at most, so it would take over 00 hours to charge that size battery. .
- Q:i need how a solar panel works, if possible make as easy to understand as possible like because of this , this happens and if you could please put a web source you got it from
- Sunlight (photons) hit a piece of silicon and knock electrons out of it. That causes a flow of electrons, which is electrical current. simple enough? a better explanation from wikipedia: A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight such as solar panels and solar cells, while the term photovoltaic cell is used when the light source is unspecified.
- Q:Can solar panels be used in conjunction with wind turbines?
- Yes, solar panels can be used in conjunction with wind turbines. This combination of renewable energy sources is known as a hybrid system and can provide a more reliable and consistent electricity generation. By utilizing both solar and wind power, the system can generate electricity during both day and night, as well as during varying weather conditions. This integration allows for a more efficient and sustainable energy production.
- Q:If I put a 5000 watt solar panel kit on my roof in Dublin (Ireland) - how much electricity would I realistically expect to get?An educated guess at a percentage of 5000w would do.
- Note that aiming is important - the sun is going to be perpendicular to the panels for only a few hours a year unless they are on an adjustable mount, so picking the time you most want power should be a factor in the angle they are mounted at - you can't keep the highest level of sun for summer into the winter time when the sun is much lower in the sky for a shorter time.
