Q: Does the new horizons has a solar panel for it power resources instead using nuclear generator?: It uses the nuclear decay of plutonium in a 'Radioisotope Thermoelectric Generator, or RTG. The heat of plutonium decay is captured and converted to electricity. Pioneers 0 and , Curiosity on Mars, and other deep-space probes use this, as the sun's light is too dim to use solar panels.

Q: What is the average size of a residential solar panel system?: The average size of a residential solar panel system is typically around 5 kilowatts (kW), which is equivalent to approximately 20 solar panels. However, the size may vary depending on factors such as energy consumption, roof space, and individual preferences.

Q: Can solar panels be used in urban areas with limited space?: Yes, solar panels can be used in urban areas with limited space. Advances in technology have made it possible to use smaller, more efficient solar panels that can be installed on rooftops, balconies, and even walls of buildings. Additionally, solar panels can be integrated into various structures like solar canopies, awnings, or vertical facades, making them suitable for urban areas with limited space.

Q: I want to make 2V 4.5A solar panel to charge my battery used in my RC car project. I just like to know how should I amplify the current for 4.5A. I need the total circuit diagram. Can anyone help me. Please. I need some affordable methods please.: The simplest way to use these panels is simply to connect the panel to your battery, with a diode in series to prevent the battery from discharging through the panel (no sunlight condition). Just connect the battery for the required charge time then disconnect it. Full sun is required, no shadows on the solar panel! ---------- .

Q: I have a panel that quot;deep breatheproduces at 4% efficiency, what can it power, It's about 4ft by 2ft: Area is 4' * 2' * (0.3048m/ft)^2 = 0.743m^2. Incoming solar (assuming optimally oriented panel) averages about kW/m^2, so 743W max gross. 4% efficiency yields 300W. Most panels are about 0% - 5% efficient, which is about W. In either case, figure about /2 the theoretical efficiency for about 2 hrs per day. so, you can run something from 50 to 50W about 2hrs per day. Too small for any appliance except maybe a laptop or light bulb. Panels typically make about 2V, not enough to run household stuff anyway. Normally panels are used to charge batteries, then an inverter takes power from the battery to run your appliances. Good luck!

Q: Can solar panels be installed on a canopy or pergola?: Yes, solar panels can be installed on a canopy or pergola. In fact, these structures can provide an ideal location for solar panel installation as they are often situated in areas with good sun exposure. By placing solar panels on canopies or pergolas, you can maximize the use of available space while also providing shade and protection from the elements.

Q: I have 2 20 watt Solar panel. I have it hooked up to solar controller and batteries to inverter. Am trying to figure out how much watts am getting. I found the voltage but how do I find the amp reading on a mutimeter?: It is possible your meter does not have the capacity to safely measure more than 300 milliamps which is too small to measure current output from solar panels. Assuming no losses in the system or components, if your meter does not have the capacity to measure 0 Amps, you will need to get one that does. Analogs are better than digitial for this. Most often the 0 Amp circuit of the meter has a discrete positive plug location for the positive test lead. Most have a common ground connection with the rest of the meter functions. If you are measuring current at the battery in the charge mode- Negative lead of meter goes to positive terminal of battery and positive lead of meter goes to the cable that was connected to the positive terminal of the battery. Since the Wattage is a nominal measurement, if you measure between the panel and controller, take measurement on one leg of the panel, as you want to measure the current with the loaded active circuit. Meter is oriented the same way as the measurement at the battery would be made above only this time the meter is between the panel and controller. At peak solar conditions, expect current to be measured at 2.5 to3 Amps or more per panel. Under optimal conditions your panel will have higher output than their ratings indicate. Open circuit can be close to 20 volts. Never short circuit the output of the solar panels. It is volts multiplied by amps that gives you Watts.

Q: How do I clean my solar panels?: To clean your solar panels, you can start by rinsing them with a garden hose to remove any loose dirt or debris. If there are tougher stains or bird droppings, use a soft sponge or cloth with mild soapy water to gently scrub the surface. Avoid using abrasive materials or harsh chemicals that could damage the panels. Additionally, make sure to turn off the system and use caution when climbing on the roof. Regular cleaning every few months can help maintain optimal performance of your solar panels.

Q: So I'm trying to figure out what to ask for my birthday because its one of the few times I can get stuff for no reason, like stuff I don't normally go to the store to buy. (i dont go to the store to get much at all anyway).Anyway, I'm interested in solar panels and led and electronics and i was wondering if there is anything not over expensive that would be cool. Some things I'm interested in:solar, wind, water energyGadgets (multitools, swiss army knives)Vibram fivefingersdrawingmaking stuff (duct tape wallets, stuff out of altoids containers)basically technology and outdoors-gear stuffoh and im 6 turnin 7 male.: solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said

Q: I can't figure out how to charge a Ni Cd (BD 8V Firestorm) battery directly with a solar panel so I've come up with an alternative which might or might not work. I thought I would connect an inverter (I found a nice 400W for $30) to my trucks battery and plug the BD Firestorm battery charger into the inverter. Then I was thinking I could use a 5W solar panel to trickle charge the truck battery and keep it connected after the Ni Cd is charged to ensure the truck battery is topped off. The truck would not be running during this process. Will this solution work? Is there a better solution?: Your 5W solar panel has to put out about 5 volts or higher to charge a 2 volt battery. 5 watts at 5 volts is only 0.3 amps, which is only enough to handle the internal leakage inside a large battery, plus a bit. If you have a 00 amp-hour battery, that panel would take 300 hours of bright sunlight to charge it. But I do agree that it will keep the truck battery charged as long as it gets sun. Make sure you put a diode in series between the panel and the battery to prevent the battery from discharging through the panel when the sun goes behind a cloud. I'd be worried that if you charged the 8 volt battery frequently, the panel would not be able to replace the lost charge, and your 2 volt battery would wind up discharged. That 8 volt battery is .2 amp-hrs (if I got the correct one). That is 27 watt-hours. Allowing for losses, you car battery will have to deliver over 30 watt hours to charge it. Your solar panel will take over 6 hours of bright sun to make up that difference. That is over 24 hours this time of year. So if you recharged it more than once every 2 days, you will lose charge in the truck battery. .
