Q: my solar panel is 5v 50 mA, and im making iphone USB charger so i need to connect + with 00 ohm resister and to data - and + so what resister will be okay..?: Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.

Q: How much energy can a solar panel produce?: The amount of energy a solar panel can produce depends on various factors such as its size, efficiency, location, and the amount of sunlight it receives. On average, a typical solar panel can generate between 250 to 400 watts of power per hour.

Q: How do solar panels affect roof ventilation?: Solar panels can have both positive and negative effects on roof ventilation. On one hand, solar panels can provide shade to the roof, reducing heat absorption and helping to keep the attic space cooler. This can decrease the need for excessive ventilation and potentially lead to energy savings. However, solar panels can also obstruct the airflow on the roof, limiting the natural ventilation and potentially causing heat buildup. Therefore, it is important to consider the design and placement of solar panels to ensure proper roof ventilation is maintained.

Q: Can solar panels be damaged by hail or other elements?: Yes, solar panels can be damaged by hail or other elements. Hailstones, strong winds, and other extreme weather conditions can potentially cause physical damage to solar panels, such as cracks in the glass surface or dislodging of components. However, most solar panels are designed and tested to withstand such elements to a certain extent, and reputable manufacturers often provide warranties to cover any damages caused by hail or other weather-related incidents.

Q: Can solar panels be used in areas with limited space?: Yes, solar panels can be used in areas with limited space. There are various types of solar panels available, including smaller and more compact designs that can be installed in tight spaces such as rooftops, balconies, or even on the sides of buildings. Additionally, solar panel technologies are continuously evolving, allowing for improved efficiency and the ability to generate more power from a smaller surface area.

Q: Are solar panels affected by shade?: Yes, solar panels are affected by shade. When a solar panel is partially shaded, it can experience a decrease in efficiency and generate less electricity. Shade can create "hot spots" on the panel, leading to the overall reduction in power output. Therefore, it is important to install solar panels in areas with minimal shade to maximize their energy production.

Q: I wanna get a solar panel to charge or 2 car batteries. Then connect the battery to a 800watt power inverter so that I can power a tv. Will the 8watt solar panel charge my batteries and around in how long?I just wanna use the panel to charge the batteries, no to use the panel directly with my electronics. Thanks for your answer and help me with that.: 8w will be .5 amps or so.That would charge a .5 amp battery in an hour.scale that up to whatever your battery amp-age is and you will have an idea.But given that car power is upwards of 40 amp/hour,your looking at 60 hours+ for a full charge on small battery.I run a 400w inverter for emergency lights and tv (get the occasional power cuts)from an old truck battery with big amps and charge it with an optimate,but in doing so I found that I had to run a amp check on power draw to find the lowest use lights.and tv,Some of the so called low power consumption compact fluorecents had widely variable draws,after testing one was found that drew .68 amp and I chose the lowest mesured tv amperage draw.not exactly an answer to your qu,but end use is the same.Running the lamp only I eventually gave up checking on the drain after about 30 hours and now just periodicaly charge the battery.Rounding off.tv draw maybe 3 amps for a small set and watched for say 6 hours would be 8 amps drawn.that would need -2 hours on your proposed set up in ideal conditions.I have kept the figures rough because there is always losses in any system .so it comes down to how much tv you watch and how much the sun shines

Q: hey so im doing this project for my technology class and i was wondering what different colours solar panels can be. also is it possible to have kentic power as a back up power if batteries dont work? thx in advance: I have only seen solar panels in a dark blue because of the material they are made of. Now the case can be any color I guess but aluminum (silver) seems to be common.

Q: i trying to make a solar panel. right now i dont have money to go and buy a copper sheet. so can i make it out of aluminum foil. if there is a way please tell me how. and what do i use for wires. i making this to charge batteries.: Making okorder /

Q: Can you connect a solar panel to speakers that use a wall outlet plug, by cutting the plug off and connect copper wire between the solar panel and cord?Confusing i know. I'm trying to connect a solar panel to speakers for a science project.: NO NO you will cause a fire and lots of damage. Do not play with the power from a wall outlet. Outlets supply 20 or 240 volts AC Your solar panel supplies low voltage (perhaps 2 volts) DC. The two are totally incompatible. Speakers require no power, just the audio signal from a power (audio) amplifier. .
