- Q:Ok so i have to solar panels to charge a battery however the panels hooked up in series does charge the battery very slowly because series connections only multiplies the voltage but leaves the current the same. Is there a way i can also hook both of them up in parallel at the same time to multiply the current for faster charge? I know i can do this with 4 panels but i dont want to spend extra. So is there a way to hook up 2 solar panels in series and parallel at the same time? Thanks in advace
- No. Series means one thing, parallel another, and they are mutually exclusive.
- Q:How often do solar panels need to be replaced or repaired roughly? Is it costly to do so?
- New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link
- Q:i need to make a mini-solar car which shouldn't cost much. it's for my science project. for now, i just found out how to make a solar panel using copper oxide, but it does not generate enough power to power up the engine of the toy car [ the small engine they used in the toys, like from TAMIA]
- Have okorder . This will absolutely save yourself!
- Q:So I want to go completely solar. Do I need the connected solar panels alone for after sundown hours; Do I need something else in order to have energy to run my entire house throughout the night?In other words do solar panels store the energy for after sun-down or do I need other devices to store the energy?
- Unless okorder
- Q:how long till a 50 watt solar panel pays itself off in buffalo, ny if its $500. i have national grid and heres the link to the rates. i am residential.
- I have a small system and do not make enough to sell back (no batteries) so it was less than 7 years BUT when you are talking about putting the initial in to a high yield div account and comparing it then I would say it took only 4 years to pay for because I was invested like many others with the capital it would have taken to get a large system and that investment LOST money while my solar pays for itself every year bit by bit. With systems now more efficient and rebates bigger and the investment alternatives not any better it is an easy choice.
- Q:What is the impact of roof orientation on solar panels' performance?
- The impact of roof orientation on solar panels' performance is significant. The orientation of the roof, specifically its tilt and direction, determines the amount of sunlight the panels receive throughout the day. Ideally, solar panels should face south and have a tilt angle equal to the latitude of the location for optimal performance. Deviations from this ideal orientation can result in reduced energy production. East-facing panels produce more electricity in the morning, while west-facing panels generate more in the afternoon. North-facing panels have the lowest performance as they receive the least amount of direct sunlight. Therefore, correct roof orientation is crucial to maximize the efficiency and output of solar panels.
- Q:I am in need of solar panels and the batteries that I can store the energy in. I need to be able to run a laptop, cell phone, and LED lights from it. When I research I see all sorts of options with regards to watts, VMPs, and AMPs. I also see that I may need a controller, an inverter, and various other components. Can anyone help me through these terms and what i need to know in order to efficiently generate and store the electricity. Thanks
- You can not really store electricity. a battery may seem like it, but it won't store it forever. What you can do, is let a professional installer install solar panels on your house. They will connect this to the mains electricity. If you are not using the electricity, then it will be distributed to others. You will receive money for this (or actually, you'll have to spend less yourself). So lets say you use 000 kwh a month (is alot) But the solar panels produce 500 kwh a month (is alot) Then you will only have to pay for 000-500=500 kwh, while you used 000 kwh. Solar panels are an investment, they cost much to install, but they will save you're energy bill.
- Q:I need a solar panel for my laptop as i am going camping in the desert, and i need my laptop. There are two choices of solar panels, One is 0 watts and 2 V and maximum power current 0.56 amps. The other one is 2 watts, 2 V and no mention of current. My laptop plug says input 00-240V and .5A and then output 5V-5A. Which one should i get for my laptop. If there are other choices please tell me ill look them up on OKorder.Thanks
- I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
- Q:I need a solar panel which can light up 4 full loaded 5 rooms appartment houses
- good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
- Q:I am looking for an average sized solar panel (Just Panel), not 2 big n not 2 small. Any idea where i can find in abudhabigt;??
- I know where in Dubai , just go to Naif road where they sell the satellite equipment , there are a couple of shops that sell all kind of solar panels and dish equipment stuff. Sorry can't remember the name, But it is right in front of the paid parking lot (the private not public one).
