- Q:I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt
- The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
- Q:Can solar panels be installed on airports?
- Yes, solar panels can be installed on airports. In fact, many airports around the world have already adopted solar power systems to generate clean and renewable energy. These panels can be installed on rooftops, parking lots, or open spaces within the airport premises, effectively reducing their reliance on traditional energy sources and contributing to a more sustainable aviation industry.
- Q:Can solar panels be used in areas with high levels of seismic activity?
- Yes, solar panels can be used in areas with high levels of seismic activity. However, proper installation and design considerations are crucial to ensure their durability and structural integrity. Reinforced mounting systems and flexible connections are typically employed to allow for movement during seismic events and minimize potential damage. Local building codes and regulations should be followed to ensure the safe and reliable use of solar panels in such areas.
- Q:What is the impact of roof material on solar panels' performance?
- The choice of roof material can have a significant impact on the performance of solar panels. Certain materials, such as metal or asphalt shingles, are more conducive to efficient solar panel installation and operation. These materials provide a stable and sturdy base for mounting the panels, ensuring proper alignment and minimizing the risk of damage. Additionally, the reflectivity and heat absorption properties of the roof material can affect the overall efficiency of solar panels. Light-colored or reflective roofs can help reduce heat absorption, keeping the panels cooler and improving their performance. On the other hand, darker or less reflective roofs may lead to increased heat buildup, potentially reducing the efficiency of the panels. Ultimately, selecting a suitable roof material is crucial in maximizing the effectiveness of solar panels and optimizing their energy generation capabilities.
- Q:Can solar panels be used to heat water?
- Yes, solar panels can be used to heat water. Solar water heaters use the energy from the sun to heat water, typically through the use of solar thermal collectors. These collectors absorb solar radiation and transfer the heat to a liquid, which is then circulated to heat the water. This renewable and environmentally friendly method can be used for residential and commercial purposes to provide hot water.
- Q:how fast does a 25watt solar panel generate power to a battery? trying to figure out a conversion factor here to get a rough estimate of how many i would need to power my house, please help?
- To figure our how many you need, take a look at your power bill. It will tell you how many kilowatt/hours you used during the month. My bill says I use about 2000 kilowatt/hours per month, or about 2000 kwh /30 days=67 kw/h hours per day. That is 67,000 watt hours. To supply that with solar panels, you have to generate at least 67,000 watt hours, but you don't have a full day to do it, since you have to do it while the sun is up. So you put the energy into batteries during the day, so you can use it at night. A 25 watt panel generates about 25 watts when fully illuminated by the sun. If you fully illuminate it for an hour, you get 25 watt hours. If you get 2 hours of sunlight a day, that would seem to imply that I need 67000 watt hours/25 watts /2 hours=45 panels. But for most of the day, the sun isn't hitting the panel fully, so it isn't going to generate the full 25 watts. When the sun is 45 degrees to the side, you only get about 70%. When the sun is 60 deg to the side, you only get 50%. And what do you do on cloudy days? And the shorter days in the winter? To make up for this, you have to increase the number of panels to make up for the loss. So in reality, I might need double this number of panels, for realiable solar power throughout the year. That works out to about 90 panels, or ,250 watts worth for my house.
- Q:Can solar panels be used in areas prone to hurricanes or earthquakes?
- Yes, solar panels can be used in areas prone to hurricanes or earthquakes. While these natural disasters can pose risks to solar panels, proper installation and structural reinforcement can ensure their resilience. Additionally, advancements in technology have led to the development of more robust solar panels that can withstand extreme weather conditions. However, it is important to consider local regulations, building codes, and additional safety measures to mitigate potential risks.
- 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:I have a solar panel I bought for a diy project and it has a small plug on the end of it, but I need to remove this plug to expose the positive and return wires so I can solder a bunch of stuff together. How do I cut off the plug without shorting out the solar panel when I make the cut? Can I just leave it in the dark a while before cutting? I don't think I can remove the wires from the solar panel end before cutting.
- Just cover the panel and cut the wire the voltage will be so low it would be like shorting out a battery
