- Q: What is the impact of roof orientation on solar panels' performance?
- The impact of roof orientation on solar panels' performance is significant. The orientation of the roof, specifically its tilt and direction, determines the amount of sunlight the panels receive throughout the day. Ideally, solar panels should face south and have a tilt angle equal to the latitude of the location for optimal performance. Deviations from this ideal orientation can result in reduced energy production. East-facing panels produce more electricity in the morning, while west-facing panels generate more in the afternoon. North-facing panels have the lowest performance as they receive the least amount of direct sunlight. Therefore, correct roof orientation is crucial to maximize the efficiency and output of solar panels.
- Q: Can solar panels be used to power a theme park?
- Yes, solar panels can be used to power a theme park. Solar panels can generate electricity by converting sunlight into energy, which can then be used to power various rides, attractions, and facilities within the theme park. Additionally, solar energy is a renewable and sustainable source of power, making it an environmentally friendly choice for theme park operations.
- Q: If you need 9400 watts, 75 amps@ 240V, how many solar PV panels do you need?
- 75 amps @ 240VDC is 8,000 watts.
- Q: I'm looking to mount a solar panel to the top of my 2003 Pontiac Montana and was wondering how i could do it without any screws? Magnets maybe?
- Build okorder /
- 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: Can solar panels be installed on factories or manufacturing facilities?
- Yes, solar panels can be installed on factories or manufacturing facilities. In fact, many industrial plants have started adopting solar power as a sustainable and cost-effective energy solution. Installing solar panels on rooftops or open spaces of factories allows them to generate clean electricity, reduce their reliance on grid power, and lower their carbon footprint. Additionally, the vast areas available in manufacturing facilities often provide ample space for large-scale solar installations, making them ideal candidates for solar panel installation.
- Q: The battery is 9ah and the solar panel is 20w
- Yes, certainly. So long as the solar panel's voltage exceeds the voltage of the battery (which is probably going, certainly if it can be a discharged battery, which is lower than 2 volts), then it will recharge the battery. Additionally, a 2 V solar panel can produce bigger than 2 volts. Nevertheless, the rate of charging is more likely to be depdendent on the availabilty of daylight. And of course, the better the capcity of the battery, the longer it takes to cost.
- Q: Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?
- I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
- Q: Are there any safety precautions to consider when installing solar panels?
- Yes, there are several safety precautions to consider when installing solar panels. Firstly, it is important to work with a licensed and experienced professional who is trained in solar panel installation to ensure proper installation and minimize the risk of accidents. Additionally, it is crucial to turn off all electrical power and follow proper electrical safety procedures before installing solar panels. Adequate fall protection measures should be in place, especially when working on rooftops or elevated areas. It is also important to consider the weight and structural integrity of the roof to ensure it can support the panels. Lastly, proper grounding and wiring techniques should be followed to prevent electrical hazards.
- Q: i trying to make a solar panel. right now i dont have money to go and buy a copper sheet. so can i make it out of aluminum foil. if there is a way please tell me how. and what do i use for wires. i making this to charge batteries.
- You can't make a solar panel to generate any reasonable amount of electricity from that. You need a semiconductor to start with, in order to have something that can generate free charge carriers(electrons and holes) from photons. Then you need a junction which can separate the charges. In principle you could make a Shottky Diode solar cell from copper if you could find a doped semiconductor to bond a sheet of it to the copper. To form a decent electric field there should be a significant difference in work functions between the copper and the semiconductor, this will generally require the semiconductor to be doped. On top of this you would need a transparent conductor (most used are things like ITO or other 'TCOs' - Transparent Conducting Oxides) to be the top electrode to inject replacement charges into the semiconductor to replace the effect of recombination current. In summary, it's difficult to DIY. You generally need complicated machinery to get decent crystal growth and/or doping.
