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: how much would you pay for a 2'x4' solar panel that puts out 24 volts and 74 watts?: Try okorder

Q: Can solar panels be used in areas with frequent thunderstorms?: Yes, solar panels can be used in areas with frequent thunderstorms. While thunderstorms may temporarily reduce the amount of sunlight reaching the panels, they are designed to withstand harsh weather conditions, including thunderstorms. Additionally, the intermittent cloud cover during thunderstorms does not completely eliminate solar energy generation, as panels can still capture diffused sunlight.

Q: What controllers and all that stuff do I need for these solar panels. Oh and the the batteries will be rigged up to a big electric motor so please leave information on how to wire the batteries to the motor...THANKS!!! 0 POINTS!: Many solar panels wired in parallel, 2 volt solar regulator, 2 volt battery e.g. 30 Ah, 240 volt inverter, autotransformer that can go down to 50 volts. There are many parameter to the electric motor missing. AC or DC, current needs for full load. How many watts the motor uses and the number of hours required will influence the solar panel, regulator and inverter specifications.

Q: Can solar panels be used for powering outdoor events or festivals?: Yes, solar panels can definitely be used to power outdoor events or festivals. They are a sustainable and reliable source of energy that can provide electricity to run lights, sound systems, food stalls, charging stations, and other equipment needed for such events. Additionally, solar panels can be easily set up in open areas, making them ideal for powering outdoor gatherings without the need for grid electricity or noisy generators.

Q: I found portable solar panels used for boats etc. and was wondering how I could effectly use them for my home instead. If you have used them in the past, please tell how they worked (good or bad).: Most people think all one needs is some solar panels to make power. It doesn't usually work that way. On a boat it is easy because most boats use batteries and DC power. If all you want to do is make DC power, you will need a battery to hook your portable unit / units to. You can then use the battery to supply power to something that uses battery power. You may need a voltage converter if the device is not 2 volt. To use the power you get from solar panels for AC power like your house has, you need a regulator, inverter, and controller to change the DC output from the panel (s) to AC and then control the power into your electric system. You also need a unit from your electric company installed. A decent minimal solar system for an average house may cost around $5000 - $0,000. It will take many, many years to pay back. For a full-use system with generator, it will probably take $30,000 - $40,000 IF you don't use it for air conditioning. If you live in an area where you have a lot of cloudy days, it will take many, many, many, many years to pay back. The reason everyone isn't using solar power is because it is not cheap and has not been cost-effective for most situations. Most Americans would not like it's inconvenience at times. It is not new science. It is in use many places and well known. It is great for some applications and as fuel and electrical power cost increase it will be used more. Don't believe the media and hollywood. They are not interested in truth. They are just interested in making you believe their way. Study and learn.

Q: Are solar panels suitable for all types of roofs?: Solar panels are suitable for most types of roofs, including flat, sloped, and metal roofs. However, the suitability may vary depending on factors such as roof orientation, shading, and structural integrity. It is recommended to consult with a solar installation professional to determine the best options for a specific roof type.

Q: I have had this 2v portable Solar Panel for my apartment for awhile. Only problem is that I have no balcony and I can barely get enough sun to use it with my Cobra 450 400-800 watt outlet converter. Can someone advise me a better method to use these? Like do I have to get more 2v solar panels? I have a small apartment and use it on one window. Also is it possible for me to buy a portable storage tank to store the energy gathered from the sun by the solar panel?: Like others have reported, the voltage may well be 2v, however the amperage is approximately .0 amps Thats the capability of photograph voltaic. relatives shops are monsterously greater useful. yet, the voltage is there, and the amperage is there, including that's- so, that photograph voltaic panel might desire to cost up a monetary business enterprise of four 2v batteries under pressure jointly in parallel.... it in simple terms could take approximately 3 weeks. it can be a great trickle cost. I play around with little 6v photograph voltaic cells, and in case you choose to work out it artwork, positioned a huge can capacitor around the photograph voltaic cellular leads for a minute or 2, then touch the capacitor to the motor leads... it is going to turn- proving the capability is actual. you in simple terms desire the Capacitor to save it up for slightly. interior the tip all of us have been given spoiled on the quite extreme performace capability of plug in electrical energy and chemical cellular batteries. Given the designed capability of those, any option source of capability is confident to be disappointing.

Q: Can solar panels be installed in extreme temperatures?: Yes, solar panels can be installed in extreme temperatures. Solar panels are designed to withstand a wide range of temperature conditions, including both hot and cold environments. However, extreme temperature conditions may affect the efficiency of the panels, reducing their overall performance slightly.
