- Q: My hubby and I are waiting to move in to our camper but have to figure out how many solar panels, batteries, etc. to get. I can't find the info per appliance for Watts and amps, but does anyone have a good, general idea of how many Watts it'd take to run the whole shabang? It's a 999, 25-foot Sportsmen tag-a-long, if that helps..It's got the following, and we'd like to run the propane things off of electric:*Refrigerator/freezer*Microwave*Oven/stove*AC/Heat*Will have a tv, phone chargers, laptop charger, but those will be unplugged when not in useThanks so much! It's such a headache.. You get SO MUCH different info from different places.. OI..
- whenever i do my gf, i use up to 900 watts of power
- Q: can anyone help me? i was thinking of installing solar panels to cut bills but would it be a waste considering its gonna need a circulating pump running almost 24/7 (which will use electricity) and even still will only provide me with quot;warmwater? also would it be possible to install the solar panels for the sole purpose of providing sufficient power to run electric heaters instead of using gas/oil? this way allowing me to have a warm house without the expensive bills. brobably talking about running 7 heaters/electric radiators.
- Are you thinking of installing electric solar panels or thermal solar panels or both? It would be better to install electric solar panels for electric heating. You can run 7 heaters as long as you do the calculations for the number of panels need for the daylight hours, and the required battery bank to supply the required power.
- Q: Can solar panels be installed on a south-facing wall?
- Yes, solar panels can be installed on a south-facing wall. In fact, a south-facing wall is often the most ideal location for solar panel installation as it receives the most sunlight throughout the day.
- 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: Are there any fire risks associated with solar panels?
- Yes, there are some fire risks associated with solar panels, although they are relatively rare. The main causes of fire incidents include faulty installation, poor maintenance, electrical malfunctions, and extreme weather conditions. However, the risk can be significantly minimized through proper installation, regular inspections, adherence to safety codes, and using high-quality components. Additionally, advancements in technology and industry regulations continue to enhance the safety of solar panel systems.
- Q: Say if i had a 2KW system is thtat just one big solar panel or does the whole system have little solarpanels together.?
- Solar panels are arrays of individual solar cells connected in series and parallel, and.. A high quality, monocrystalline silicon solar cell, at 25 °C cell temperature, may produce 0.60 volts open-circuit (Voc). The cell temperature in full sunlight, even with 25 °C air temperature, will probably be close to 45 °C, reducing the open-circuit voltage to 0.55 volts per cell. The voltage drops modestly, with this type of cell, until the short-circuit current is approached (Isc).
- Q: I have a solar panel 7.5V .25W 50mah, connect 2 in parallel to power a RC boat. The boat use to run on 6cell battery pack - 7.2V 800Mah.The dc motor requirement based on the provided battery pack, i assume would be 7.2V and rated at (7.2V * .8Amp) = 2.96 Watt.Would two of my solar panels run this DC motor ?are my calculations or understanding correct ?do lend a hand dear ''world''
- solar cells are not rated in mah, they are rated in ma or amps. I'll assume this one is 50mA. Two in parallel will give you 300mA, so that will charge a 800mA-hr battery in 800/300 = 3 hours. Theoretically, in bright sunlight if the array is exactly at right angles to the sun's rays. The problem is, depending on the type of cells, the battery pack will need 8 volts or so to charge, and your solar cells won't deliver that. If the sun is at an angle, you may get only 3-5 volts. so you have to put them in series, so you will get only 50mA out of them, which will charge the battery in 6 hours of bright sunlight. Would two of my solar panels run this DC motor ? If the motor is .8 amps, you need the battery, the arrays are not near enough. Or are you attempting to replace the battery pack with the solar array? Your english makes that difficult to understand. If so, put them in parallel to get the 300mA, but that would run the .8 amp motor very slowly. If you had 2 of the solar panels, it might run at close to full speed if the sun is bright and shining directly on all the panels. But where did you get the .8 amps for the motor? The 800Mah rating of the battery has ZERO to do with the motor current. So the answer above is based on your number, which I suspect is totally wrong. .
- Q: can solar panels have glass between the panels and the sun?
- As above, but also make sure the panels you use will still produce if partially shaded. Some older panels will quit producing if you so much as put your hand over a small portion of it. Newer ones don't do this but are more expensive. As you may need more panel area to produce enough energy to fill a battery (if that is how you go) make sure you have the room/roof area for additional panels.
- Q: i really love the idea of solar and want to start out small, so i'm new to this.I plan on getting an 85w panel to charge my laptop. what other equipment is needed to accomplish this?would i need to get a battery or does the solar panel hook directly to the laptop. Does one end just lead to a conventional outlet similar to a wall outlet?could someone please give me a detailed explanation with options about this? i would greatly appreciate it.
- humm..... .need HUGE solar panel (alot) 2. wires 3. aligato clips . put the panels on the roof 2. use the aligator clip to clip the wire from the panel to the bars of the pluger of the comp. charger 3.tada mark me best:)
- Q: I don't want to spend a fortune, maybe talking like over $200 but I would like to power my computer, the monitor, my tv, and a small fridge.I looked up the price on some but it does not make any sense to me because it says that it has reached the price of less than $ per watt but if I look up a 20 watt solar panel it is $560 dollars. Why would it not be $20 because they said $ a watt.Where would be the best place to buy the cheapest solar panels?
- The first thing you need to do is look at the power needs of those things. Add up the power (Watts) to run all of those things at the same time. Then you're also in trouble if you plan to run those things when it's not peak sunlight, so you'll need some battery setup. And some appropriate fuses and diodes and a controller of some kind to protect your panels and the things you are powering. It would take a bit of physics and electrical knowledge to do this and do it safely. I built a car that ran off of solar energy in a college project last school year. We had a bank of Kyocera 50 Watt panels that cost 250 each. So, you won't be able to do this for under 200, sorry. If you wanted to spend more I could figure out everything you needed for you, but money will be a problem. And I don't know if it will really be cost effective.
