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 ski resorts?: Yes, solar panels can be installed on ski resorts. In fact, many ski resorts have already started implementing solar energy systems to reduce their carbon footprint and lower their dependence on traditional energy sources. Solar panels can be mounted on rooftops, parking structures, or even on the ground near the resort area, providing clean and renewable energy to power various facilities and operations.

Q:Can solar panels be installed on a historical building?: Yes, solar panels can be installed on a historical building. However, it is important to consider the impact on the building's architectural integrity and historical significance. Careful planning and consultation with preservation experts may be necessary to ensure that the installation is done in a way that respects and preserves the building's historic value.

Q:Mono-crystalline or poly-crystalline solar panel?: All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.

Q:Why does the new 200 Toyota Prius have solar panels at the top of the vehicle?: The solar panel powers the fan in the solar-powered ventilation system. The ventilation system helps to keep your car cool while parked out in the sun. If your car is cooler, then when you get into it after parking somewhere the AC won't have to work quite so hard to get you comfy when you start your car. Less AC use means less hybrid battery use (since the hybrid battery powers the AC), which means that your gasoline engine will run less (to recharge the hybrid battery), meaning better fuel economy for you.

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:So I want to power one of my car fans with some solar panels. I ordered quite a few and I want to power one of my fans under the hood. I've already disconnected the fan and pulled it out of the car to test it later.What all do I need besides the panels, fan, and wiring to make this work. This fan will not be tied to any other system. Currently, the fan is not operated by the car or any system of the car due to a modification made to the automobile allowing me to disconnect it from use months ago.Using the fan powered from the solar panels would help with the modification to increase air flow and speed into the area.Could someone please help me by telling me what else I need to make the fan operational from here?: The solar panel doesn't output enough power to run the fan directly, your best bet would be to just hook the fan back up to the battery, and then rig the solar panels up to help charge the battery and remove some of the load from the alternator. If you're trying to reduce your emissions/increase fuel economy then you'd be better of setting up a switch to disconnect your alternator when its not necessary to have it on. The alternator runs off a belt from the engine which requires some of the power output from the engine. Having this connected all the time increases the amount of gas used (marginally) but you'd be saving more gas doing that and using the solar panels to keep the battery topped up.

Q:What is the impact of bird droppings on solar panels?: Bird droppings can have a negative impact on solar panels as they can reduce the efficiency of the panels by blocking sunlight. The droppings can create shadows and reduce the amount of sunlight that reaches the panels, leading to decreased energy production. Additionally, the acidic nature of bird droppings can damage the surface of the panels if not cleaned regularly, potentially reducing their lifespan. Therefore, it is important to regularly clean and maintain solar panels to ensure optimal performance and longevity.

Q:how many solar panels in a grid tied system would it take to take see a difference in your power bill?: I just costed an 85W panel I found online as paying back in 30 years. And that's without the inverter. If you want to do it to save money, look on surplus sites for chipped cells and make your own panels. You can then get the pay back time down to about 5 years, even with the 9.60/kWh price here, which is lower than many places.
