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: You okorder / Solar Pro Magazine another of their publications

Q:solar panels!!they are fantastic! cause they are the new way of quot;chargingyour home, without killing the earth!would you install them, or not? and make sure you say WHY: I would because it will help me consume less energy and it will not have any effect on our planet earth. AlsoThere is no waste involved like you would get with fossil fuels, and no pollution to expel into our atmosphere. In the middle of winter we would normally be using enormous amounts of fossil fuel, proving very costly. Residential solar power does not give us this problem. This will help our planet alot

Q:It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.: you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .

Q:I would like to connect a solar panel to a small fan. I am not sure as to what is needed to actually quot;connectthe two together. Any help is appreciated.: If your fan uses a tiny motor like in a cell phone vibrator, you might be able to use just a few solar cells. Otherwise, you might find the voltage and current from a pre-assembled panel, and get a fan that uses less power. You will then likely need electronics to match the two up, and maybe a battery to keep it going when the sun goes down.

Q:I have heard you can make your own solar panels.... But How?Where do you start? Is it cheap, or should I just BUY them already made?: If you're thinking of solar electric panels then forget it. It you just want to dabble in solar power then shop around for a 5 volt panel. Find out how many watts it puts out and then divide the cost $$ by the wattage. The lower the cost per watt the better of a deal you'll be getting That's generally speaking of course because it doesn't take quality into account but it's a practical way to compare panels. On the other hand, it you want to make a solar panel that will heat hot water then it's a different story. You can have a lot of fun with that project and you'll find a lot of plans on the Internet.

Q:Are there any fire hazards associated with solar panels?: Yes, while solar panels themselves do not pose a significant fire hazard, there are some potential fire risks associated with their installation and operation. These risks primarily stem from electrical malfunctions, such as faulty wiring, improper installation, or damage to the electrical components. Additionally, in rare cases, solar panels can contribute to the spread of fire by acting as a source of fuel or by hindering firefighting efforts due to their presence on rooftops. However, with proper installation, regular maintenance, and adherence to safety guidelines, the fire hazards associated with solar panels can be minimized.

Q:Can solar panels be used in areas with high levels of saltwater?: Yes, solar panels can be used in areas with high levels of saltwater. However, it is important to choose solar panels that are specifically designed for such conditions and have corrosion-resistant materials. Additionally, regular maintenance and cleaning of the panels may be required to prevent damage from salt build-up.

Q:Can solar panels be installed in a desert environment?: Yes, solar panels can be installed in a desert environment. In fact, deserts are often ideal for solar panel installations due to their high levels of sunlight and minimal cloud cover. The dry climate also helps to minimize dust buildup on the panels, making maintenance easier.

Q:What is the payback period for solar panels?: The payback period for solar panels refers to the time it takes for the savings from reduced energy bills to equal the initial investment in installing the solar panels. The payback period can vary depending on factors such as the cost of the panels, the amount of sunlight in the location, and the local electricity rates. On average, the payback period for solar panels is around 5 to 10 years, but it can be shorter or longer depending on these factors.

Q:Are there any safety concerns with solar panels?: Yes, there are some safety concerns with solar panels, although they are generally considered safe. The main concerns include the risk of electrical shock or fire due to improper installation or maintenance, potential harm from falling panels or debris during severe weather events, and exposure to toxic materials used in panel manufacturing. However, these risks can be minimized through proper installation, regular maintenance, and adherence to safety guidelines and regulations.
