- Q: I need to use solar panels to charge lead acid batteries in an off-grid application. I understand that solar panels have a open circuit maximum voltage and an maximum amperage under no resistance, and that one can optimize the power output by regulating the load (resistance). If so, is just connecting 2 -volt solar panels to a lead-acid battery inefficient? Are there devices that will maximize 2 volt output power (by varying the resistance)? Am I on the right track here? Thanks for any help.
- The answer is actually quite complicated, but if you're planning on building just a very small system, most likely, the panel will be small and weak. In this case, connecting a panel that is 8 volts open circuit directly to a lead-acid battery is probably the most efficient way to charge. There are charge controllers that you can buy, some of which actively track the maximum power point for charging your battery. Unfortunately, those controllers might eat 5 or 0 watts, just to get you another few percent of charging efficiency. If your panel is only 50 watts in the first place, you can see that this is not a good deal. If you're getting serious panels (clue: price $500 each), then you may very well benefit from a charge controller with MPPT (max power point tracking). Lead-acid, either a flooded cell like your car battery, or AGM, are the standard for solar energy storage. Lithium ion is better in many ways, being less sensitive to temperature, state of discharge, and they are also lighter. Charging them is also more straightforward with the right circuitry. The problem is, they cost like $500 per kWh, compared with less than a tenth that price for lead-acid.
- Q: I am writing a lab for school and I need to know who invented solar panels? Any help would be great.
- Many people think that solar power is a new concept. That couldn’t be farther from the truth. Harnessing power from the sun has been dated back to ancient civilizations. The below link is a timeline researched by the Department of Energy that outlines the major historical milestones of solar power.
- Q: How do solar panels perform in extreme temperatures?
- Solar panels perform best in moderate temperatures, typically between 25 to 35 degrees Celsius. However, extreme temperatures can affect their performance. In extremely hot temperatures, solar panels may experience a decrease in efficiency due to an increase in heat-induced resistance. On the other hand, in extremely cold temperatures, solar panels may experience a slight increase in efficiency, as lower temperatures can reduce resistance and improve conductivity. Nonetheless, most solar panels are designed to withstand a wide range of temperatures and can still generate electricity in extreme weather conditions.
- Q: I am moving to Hawaii and the house we are living in has independent electricity. (solar panels and gas powered generators.)
- Any source capable of providing 300W should work but I'd recommend you get a UPS if you are relying on either of the two power sources you've mentioned.
- Q: Can solar panels be used to power a disaster relief operation?
- Yes, solar panels can be used to power a disaster relief operation. Solar panels are a viable and sustainable source of energy that can be deployed quickly in disaster-stricken areas. They can provide electricity for charging communication devices, running medical equipment, powering lighting systems, and supporting other essential operations during relief efforts. Additionally, solar panels are independent of existing power grids and can be set up in remote or inaccessible locations, making them an excellent solution for providing energy in emergency situations.
- Q: How do solar panels affect property value?
- Solar panels can have a positive impact on property value by increasing the overall value of a property. Studies have shown that homes with solar panels tend to sell for a higher price compared to similar homes without solar installations. The energy savings and potential income from selling excess electricity to the grid can make a property more attractive to buyers, leading to a higher selling price and increased property value.
- 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: Can solar panels be used in areas with high levels of bird or bat activity?
- Yes, solar panels can be used in areas with high levels of bird or bat activity. However, certain precautions should be taken to minimize potential risks. For instance, installing bird deterrents like netting or spikes can prevent birds from nesting or perching on the panels. Similarly, incorporating specialized designs or modifications can minimize the impact on bats. By implementing these measures, solar panels can coexist with bird and bat populations while still harnessing the sun's energy efficiently.
- Q: Does anyone own any and would you recommend them? right now i only own solar stake lights and i use them during the summer in my yard. But during the winter i take them out because they don't charge well. I live in toronto canada where it snows a lot during the winter, would it even be worth it to buy solar panels? Would they get covered with snow if the were mounted on my roof and get ruined? I plan on buying some when i purchase my own home.Any info would be appreciated:)
- The best sort of solar panel for $ to energy is the hot water type that use a vacuum tube system to heat your water. This saves you money on heating water and is relatively cheap to install compared to other things like wind or PV solar. I'm not too sure about where you live (I'm in the westcountry of the UK where wind energy IS viable... but usually it isn't). The best sort of Photo voltaic solar panel (that makes electricity)is still expensive yet very reliable as they only need photons to fall on them not neccessarily full sunshine and they are improving all the time. It depends on the pitch of your roof as to whether snow settles on them. One can have a system that sells power back to the national grid and then you buy what you need with a discount for what you produce. Obviously if you can afford enough panels one could even make a profit. Or you can go self-sufficient, but then you need batteries and an inverter to convert your 2 volt battery output back to 20 volts or whatever you use (it's 240 volts in the UK). Then it's a matter of how efficient your batteries are in amp hours. Dry mainainence free deep cycle batteries are best for this job and quite expensive still. Wind generators are only really practical if you can mount them high enough from the ground to where there is more constant wind. As I said that depends where you live and the prevailing winds. The very small ones are basically useless except for emergency lighting or something, so one needs a fairly large turbine to produce enough power for a modern home so planning restrictions should be considered when going down this road. For now, solar power is definitely the way to go, even as far North on this planet as Canada and the UK. Good luck. Once you have the system it's basically FREE energy!
- Q: Okay, so I have a science fair coming up soon and I need help with my project. SO - What should I use to demonstrate with the propeller? A toy boat? Plane? And I only have mini solar panels ; so how do I put the solar panels on the toy boat/plane to make the propeller move off of the sun's energy? Thanks. Steps please!
- Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
