Q: I know that one LED can't power a solar panel. I have found 40 kmcd LED's on OKorder. I know that several of them (28 totale each one with a 470 ohm resistor all at 2 VDC) can show a reflection on a wall in daylight 60 feet away..
The 40 kmcd rating is a measure of luminous intensity (how bright it looks), not a measure of output power of the visible light. We can estimate the performance of your proposed system as follows: The LEDs on OKorder each are rated about 20mA maximum at about 3.2V, or 64mW (milliwatts). If you use 470 ohm resistors connected to 2VDC, the current that will flow, per LED, will be about: (2V-3.2V)/470ohm = 0.0872A = 8.72mA The power taken from the 2VDC power source will be: P2v = 2V x 8.72mA = 224.6mW (per LED) The power input to each LED will be about: Pled = 3.2V x 8.72mA = 59.9mW (per LED) The LED has a luminous efficiency that can range from about 4.2% to 22%. This efficiency is the ratio of the amount of visible light output (in watts) divided by the input power (in watts). The OKorder listing doesn't identify the output power level (either in watts or in lumens), so let's assume a 0% efficiency. The LED output power will be about: Pout = 59.9mW x 0% = 5.99mW (per LED) A solar panel converts visible light to electrical energy with an efficiency that ranges say about 6% to 8%. Suppose the solar panel efficiency is 2%. Then the electrical power output by the panel will be about : Pe = 5.99mW x 2% = 0.72mW (per LED) If you shine 00 LEDs on the panel, the output electrical power will be 00 times that amount: Pe00 = 0.72mW/LED x 00 LED = 72mW <===ANSWER The power taken from your 2V source will be about: P2V00 = 224.6mW/LED x 00 LED = 22460mW = 22.46W The system efficiency will be about: Eff = solar output / battery input = Pe00 / P2V00 = 72mW / 22460mW x 00% = 0.32% SUMMARY: If you shine 00 of the LEDs on the panel, you will capture back about 0.32% of the energy expended, or regain about 72mW.
Q: Can solar panels be installed on a boat or yacht?
Yes, solar panels can be installed on a boat or yacht. Many boat and yacht owners opt to install solar panels to harness the sun's energy and power their electrical systems on board. These panels are typically mounted on the boat's roof or deck, and can provide a sustainable and renewable source of power for various applications while out on the water.
Q: I am doing a project on solar energy at the moment and I was just wondering how.
my theory is that when sunlight hits the panel it excites the electrons from the rays there by making them move more quckly and attract them to a source with less elctrons making the panel positiveli charge and the electron collector negatively charged thereby connecting the negatively charged particles to which ever body it wishes to donate it too thereby causing electric charges
Q: Can solar panels be used in areas with high levels of dust storms?
Yes, solar panels can still be used in areas with high levels of dust storms. However, it is important to ensure regular maintenance and cleaning of the panels to prevent dust accumulation, which can reduce their efficiency.
Q: I live in Los Angeles area, I see the ads that, they will install solar panel for $0. I would like to know what is the catch ?Thanks You.
The catch is you pay a monthly electric bill to the company that installed it. There are a couple ways to pay for solar power. One way is to pay the full cost of installing it then get all the power it makes at no cost. The other way is they install it for free and they become like a second power company. You pay them for the solar power and still pay your electric utility for any power from their generator that you use. The idea (usually a promise) is that the monthly rate will be lower than the power company charges. I would prefer to pay the full cost of the installation and own the power it makes from then on. But you need to have enough cash, or the ability to borrow enough, to pay that way.
Q: I'm doing a project for school where I will buy a solar panel and utilize/improve the power output of the panel. I want the panel to have an improved amount of energy output compared to the original. My budget for the solar panel itself is ~$00. Anything else that will be needed is covered.Also, I will be comparing the power by lighting a light bulb and checking to see the output energy of the panel.Where or how should I approach this project?What are the parts of the solar panel that I will need to buy?What factors could I change/improve to improve the overall energy output?What are the things (other than the panel) that I will need to buy?How can I attach a light bulb to the solar panel?
when you're in Malaysia, i'm no longer effective why you desire a heater, except perhaps a water heater. For that, use a photo voltaic heater right away. For the electrical energy, the most value-efficient thanks to do that's to stay linked to the grid, and offset your bill with photo voltaic. That way, you do not favor to oversize the photo voltaic for contingencies. there'll be compromise on your way of existence, each and every thing that plugs into the wall today will nevertheless plug into the wall and artwork advantageous.
Q: Can solar panels be installed on shopping malls or retail centers?
Yes, solar panels can be installed on shopping malls or retail centers. In fact, many commercial properties are now adopting solar energy systems to reduce operating costs, promote sustainability, and generate clean electricity. The large roof areas of shopping malls and retail centers offer ample space for solar panel installations, making them ideal candidates for harnessing solar power.
Q: Can solar panels be installed on warehouses or industrial facilities?
Yes, solar panels can be installed on warehouses or industrial facilities. In fact, these types of buildings often have large rooftops or open spaces that are ideal for solar panel installations. This allows them to generate clean and renewable energy, reduce their reliance on traditional power sources, and potentially save money on energy costs.
Q: hi guys, i need help, okay lets say i decide to put solar panels near a place where its inhabitated by people, what kinda of environmental factors should i consider? Will the solar panels cause any damage to the enviromnent around it? Will it affect the plant and animals around it? should i consider the weather? its for my class so if u guys can help thankx.
I wouldn't worry about what the solar panel is going to do to the surrounding environment, I would worry about what the surounding environment is going to do to the solar panels.
Q: Can solar panels work at night?
No, solar panels do not work at night as they rely on sunlight to generate electricity.
