Q: I need to power a series of meraki wireless repeaters that plug into a standerd wall outlet. consuming 5v or .08 amps However I need this in a remote location (like out in the middle of nowhere) Using A solar panel as power supply and a battery to store the energy but, how and what do I use to convert the energy coming from the solar panel to the battery and the batteries power supply to match the needs of the meraki wireless repeater? How do I make this as compact as possible? Do I need a ac/dc converter? or dc/ac converter? Any suggestions or solutions would be great !: First things first. 5 Volts @ .08 amps would be .2 Watts. therefore you would need at least the same amount from a solar panel to replenish the batteries. But what puzzles me is the notion that plugging it in a wall outlet ? If you use 20 V @ 0.08 then the power consumption is 9.6 Watts And what is a meraki wireless repeater? I never heard of one. I'm a FCC licensed Ham and have some idea what is available. If you need 5 volts DC, you could use twelve Ni-cads in series and just keep them trickle charged with the solar panel That would make it compact. If you were to use an automotive battery (or motorcycle), then you would need a DC/DC converter.

Q: i want to go off grid with solar panels but i need to know how many vots and watts i need to power my house: Complex question.... Let me try to simplify it some: Make a list of every electrical device you MUST have. Add to the list how many hours a day it is actually ON. Add to the list how many watts (listed on the label or Volts times Amps) the device uses. (If you have a measuring device, use it.) For each item, multiply volts times hours = watt-hours (this is total energy used per day). Also, add the watts column for all the devices (this is the maximum instantaneous power to be used). Your solar panels should be able to provide power for your total load, so your panel's output power should equal the maximum instantaneous power used. If you can limit how many devices are used at a time, you may be able to reduce the panel size. Look at the total watt-hours. This is the total energy. Your panels generate maximum output when they are perpendicular to the sun at noon on a clear day. They generate reduced output in the morning and afternoon. They also generate substantially reduced output on cloudy days. Also, did you want electricity at night? On cloudy days? You will need batteries.. lots of batteries. And batteries are inefficient.. figure about 50% efficiency after a few years. Basically, here is a very rough formula: Panel_watts = Load_watthours / hours_sun_daily / 60%_angle_efficiency / 50%_battery_inverter_efficiency Once you've figured out the panel's watts, watts/volts=amps. Your system can be 2V with more amps, or 48V with /4 the amps... but the watts are the same. Just the wiring is different. For the battery bank, you need to determine how much backup power you will need for nights and cloudy days. Look at the watt-hours needed at nite, multiply it by the number of days and then by 2, to allow for battery aging. Unless you only have a couple devices and an LED light or 2, it is going to be VERY expensive.

Q: I'm re-doing my roof. Is it workable?Can I get a government grant or something to put solar panels on my roof?I know they did something like that for windows.: I don't think you can get a government grant? At least not just yet... But, you can get a nice Tax break for having installed solar panels on your home or for some their backyard works well. But, again you must be aware that having professionals install these panels can be quite costly. If you don't mind getting your hands a little dirty, tackling this project on your own isn't as hard as you might think! And you will be amazed at how much money you can save from the start. And if you get the family involved all the better! Building affordable solar panels for your home, is no pipe dream...But, you must be willing to do the work yourself! That's usually where most people fall short.

Q: Is there a cheaper way on how to make your own solar panels ? Can someone share their real life experience ? Thank you.: It used to be possible to get broken solar cells for free from solar cell and solar panel manufacturers and then it's just a matter of labouriously measuring the voltage and current characteristics of each fragment and soldering them in a combination of parallel and in series to get a crude solar panel with the desired output but the manufacturers have caught on and now sell the broken fragments by the pound so it's not really a cheap solar panel anymore but it's still very labor intensive and results in a fragile solar panel that is readily damaged and quickly degrades. Not really worth the trouble any more.

Q: Am using 800watts sukam inverter and have 55watts panel. What controller can i use to connect my solar system to have a max power . Already i have 200 Amp/hr battery: If that 55-watt panel has an open circuit voltage of 7-8 volts, you may get more efficiency by omitting the charge controller completely, and connecting the panel straight to the battery. 55 watts is marginally too small for a 200 AH battery at 2 volts, by the way.

Q: What happens to solar panels during a power outage?: During a power outage, solar panels are unable to generate electricity because they rely on the grid to function. This is because most solar panel systems are grid-tied and do not have a battery backup. Without power from the grid, solar panels are effectively rendered inactive until the power is restored. However, there are alternative solar panel systems with battery storage that can continue to provide electricity during an outage.

Q: Can solar panels be used for powering a wastewater treatment plant?: Yes, solar panels can be used for powering a wastewater treatment plant. Solar energy can be harnessed and converted into electricity, which can then be used to power the various components and processes involved in wastewater treatment. This renewable energy source helps reduce reliance on non-renewable fuels, lowers operational costs, and minimizes the environmental impact of the treatment plant.

Q: i am very much interested in making a solar panel, my problem is where i can acquire the main components in order to build it, i am staying here in abu dhabi UAE i'm always searching on the internet for shops that can provide me a DIY kit but i did not find one, i need somebody who knows where i can get these things, please let me know.: Have okorder . This can immediately instruct each and every one!

Q: I am learning all about heat radiation in Physics. There is a question I am doing about Solar panels. It asks, why do glass covers improve the efficient of solar panels? I dont really understand. How do they?? thanks :D x: Clear glass will allow most of the electromagnetic energy of sunlight into the air-tight volume of the solar panel. The light strikes the black coated metal tubes and the black coated backing, and is absorbed as heat. Part of this heat will radiate as infrared radiation, and much of this will leave through the glass. But a great deal of it will initially remain in the metal as heat. This heat will be partially transferred to the surrounding air, but because the glass stops the mixing of this air with the rest of the atmosphere, this heat will stay mostly contained within the solar panel. If the glass were not there, there would be a huge loss of heat into the surrounding air.
