- Q:Do solar panels require regular maintenance?
- Yes, solar panels generally require regular maintenance to ensure optimal performance and longevity. This includes periodic cleaning to remove dirt, debris, and snow, as well as checking for any possible damage or malfunctioning components. Additionally, regular inspections and maintenance by professionals are recommended to identify and address any potential issues or inefficiencies.
- Q:i really need to know howbecause im building a solar powered car for science fair :]thank you!
- get some stuff, put it on the other stuff
- Q:What is the impact of roof pitch on solar panels' efficiency?
- The impact of roof pitch on solar panels' efficiency is significant. A steeper roof pitch allows for better solar panel orientation towards the sun, maximizing the amount of sunlight they can capture. This leads to increased energy production and higher overall efficiency. However, a flatter roof pitch can still be suitable for solar panels, as long as they are properly tilted or mounted to optimize sun exposure. Ultimately, the ideal roof pitch for solar panels depends on factors such as geographic location, climate, and the specific solar panel technology being used.
- Q:How do solar panels affect the property's carbon footprint?
- Solar panels can greatly reduce a property's carbon footprint by generating clean and renewable energy. Since solar panels generate electricity by harnessing the power of the sun, they do not emit any greenhouse gases or pollutants during operation. By reducing reliance on fossil fuels and grid electricity, solar panels help to offset carbon emissions that would have been produced by traditional energy sources, thus positively impacting the property's carbon footprint.
- Q:how much energy or electricity a solar panel produces?
- how many solar panels do I need for my house if in average I consume 880 kwh
- Q:I'm doing a project for school and I'm a little confused about energy and solar panels. I'm looking to propose installation of solar panels to power the computer lab at my school. From what I've read a computer and monitor use roughly 350 watts per hour. I was looking at solar panels and it says they produce various wattage. For example, I was looking at one rated at 200 watts. Does that mean 200 watts in a day? Or per hour? Please help.
- The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
- Q:Can solar panels be used in hot climates?
- Yes, solar panels can be used in hot climates. In fact, solar panels are more efficient in hot climates as they thrive in high temperatures. However, it's important to ensure proper installation and maintenance to prevent overheating and maximize their performance.
- Q:I need to build a battery array to use with my solar panels I just bought. I want to be able to store enough energy to be draw from it at night, possibly around the clock. Is there a down side to using the deep cycle battery I bought from autozone and 6 or 7 more just like it, or do I need to get some other battery?
- There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
- Q:Can solar panels be installed on water bodies or reservoirs?
- Yes, solar panels can be installed on water bodies or reservoirs. This is known as a floating solar power plant or floating photovoltaic system. It involves placing solar panels on floating platforms that are anchored to the bottom of the water body or reservoir. This innovative approach allows for the utilization of otherwise unused space, reduces evaporation, and provides cooling benefits to the solar panels, increasing their efficiency.
- Q:please no dumb answers and list where you got the info.Also how much does it cost to install solar panels for a regular sized house?
- Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
