- 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: Can solar panels be used for powering public transportation?
- Yes, solar panels can be used for powering public transportation. Solar energy can be harnessed through solar panels and converted into electricity, which can then be used to power electric buses, trains, trams, and other forms of public transportation. This helps reduce dependence on fossil fuels, lower greenhouse gas emissions, and promote sustainable and clean energy solutions for transportation systems.
- Q: We have LED at the output of 40 watts and is used for 0 hours giving us 400 Watts-hr of energy consumed.Rechargable batteries needed are 2 V. 400/2 gives us 34 Ampere-hour battery needed. If we want it for 3 days, It would be 34x3=00 Ah. So the battery needed 00 AhNow how do I select the solar panel which can charge this/these batteries? What should be its rating?
- Be aware that you cannot discharge the full capacity of a lead-acid battery without destroying the battery. With a normal battery of this type, you would only want to discharge about 20%, so you would need a 70 AH battery bank. For the 3-day requirement, 500 AH. This is still within reason. If you didn't have the 3-day requirement, you might consider going with NiMH batteries. Back to the 500 AH bank, you would usually charge at at least 5% C, or 25 amps. At the 5 volts that you need for charging, this is 375 watts. Possibly you could go as low as 200 watts.
- Q: Actually I want to convert my home electricity on Solar Panel to cut down electricity costI have 2 AC's, a refrigerator, 3 Television, 2 Computers, 4 Fans etc
- good okorder lots of good ideas there
- Q: Is it as simple as buying the panels, an inverter and plugging it into a wall-socket, assuming it would just send power back into the outlet and supplement my house's electrical usage, or... Is it not that simple?Remember, I'm talking about a SMALL system, and I don't care how little power it'd make, or how uneconomical it would be.
- How to tie small solar panel system into my house's electircal system? It's very complicated. Just for starters, if you plugged your solar panel into your electrical outlet, you would probably see smoke and fire, not electricity. Of course anything CAN be done. But this one is truly unfeasible at the consumer level. The only way to send power back into a live system is to synchronize the phase voltages. In your case you would require the solar panels, a battery backup system, a voltage inverter and some type of industrial synchronizer (probably a generator) so you could sync your inverter output to the utilities output. Solar is still more of a standby or supplemental type power at this time. The easiest way is to supplement your hot water by using solar panels to heat water rather than create electricity. If money was not much of an option then you could theoretically run your whole house without the need for any synchronization but have a gasoline or diesel generator to keep your battery pack topped up when needed.
- Q: I'm writing a lab and I have to put information about solar panels in it. The history, who started them, why they are useful etc. any good sites that can help me?
- Yup, just Google solar panel history and away you go.
- Q: I have four power packs for solar lights. They have 3 AA .2volt batteries of 2450 mAh capacity installed in series for a total supply voltage of 4 volt maximum for the lights. I want to charge all four packs at once off a single 6 volt solar panel. With the four packs wired in parallel, what capacity output (wattage) panel do I need to charge the batteries in an 8 hour day?
- Each battery pack has the equivalent of only 2450mAh capacity at 4 volts, so for 4 battery packs like that, a total capacity of 9800mAh. Assuming that the solar batteries have no charge left after being on all night, and that day charging time equals night discharging time, the theoretical wattage would be 9800mA times 6 volts = 59 watts. Of course, battery charging is not 00% efficient, so you need more wattage than that. Plus, solar panels are rated at peak output at midday, while at other times of day their output is less than rated. And, the charging in parallel isn't a good idea, because real batteries have different internal resistances, some batteries would become overcharged, while other packs wouldn't get the charge they need.
- Q: Can solar panels be installed on a multi-story building?
- Yes, solar panels can be installed on a multi-story building.
- Q: I want to be more self sufficient and get solar panels for electricity in a small house any tips will help. i need to know how many watts is enough and ect.
- To clarify your thinking, ask yourself whether your goal is really to be more self-sufficient, or to save money. For most people, I think when they say they want self-sufficiency, they really mean they want to save money, not pay more. The money-saving route may come through putting in more insulation on the house, or double-pane windows, or energy-efficient appliances. Solar might play a part, but the kind of solar that pays back well (if at all) is the type without batteries. That doesn't give you self-sufficiency - if the power company has a blackout, the solar electric will automatically disconnect. Your power company may offer a free energy audit to help you save money. And if you are interested in pursuing solar electric (or even better, solar hot water), check with a local installer. They can size your system and give you a free quote.
- Q: Can solar panels be installed on flat roofs?
- Yes, solar panels can be installed on flat roofs. In fact, flat roofs are often considered ideal for solar panel installations due to their easy accessibility and the ability to optimize panel positioning. However, it is important to conduct a structural analysis and ensure proper waterproofing measures are taken during the installation process.
