- Q: I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?
- You can do this, but it isn't the best way to go. There is no problem with joining the solar panels. There are two ways to do this, in series and in parallel. A series combination will add the voltages that each panel is producing together, but not the amperages. For example, if five panels are producing 6V at 300mA each, the end result will be 30V at 300mA for a series array. A parallel combination combines the amperages of all the panels, but not the voltages. So, in our earlier example, five panels at 6V and 300mA would provide 6V and 500mA (.5A) if wired in parallel. Series-parallel combinations are also possible, giving some of the benefits of each method. This would probably better understood by doing a quick search on Google Images for series, parallel, and series-parallel. You CAN connect the solar panels directly to your battery bank with no regulator. Unfortunately, without a regulator, the connection is two-way. When the sun is out and the solar panels are producing more voltage than the batteries, the batteries will charge. However, when the panels are producing less voltage than the batteries, the batteries will instead send power into the solar panels, which will be dissipated and wasted. The panels may charge your batteries during the day, but they will discharge them at night.
- Q: Ok, so I've been having much success with the joule thief circuit and a LED, but i tried hooking it up to a small solar panel that can put out 2.5v on it's own, and can light up a white LED dimly by it self to the joule thief and it will not work ....my question is why? I already trouble shooted it, the circuit is not the problem, is it the amount of amps the small solar panel is capable of? not enough?
- Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
- Q: Can solar panels be installed on a library or educational institution?
- Yes, solar panels can be installed on a library or educational institution. In fact, many libraries and educational institutions have already embraced solar energy and installed solar panels on their rooftops or surrounding areas. This helps them reduce their carbon footprint, save on electricity bills, and serve as a sustainable example for the community.
- Q: How do solar panels affect satellite dish reception?
- Solar panels can potentially interfere with satellite dish reception if they obstruct the line of sight between the dish and the satellite. However, modern satellite technology and proper positioning of both the panels and the dish can often mitigate any negative impact on reception.
- 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: Is this a good kit for building a solar panel?
- Only okorder /
- 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.
- Unless you're very rich, you won't be able to afford solar panels that can meet the average demand of a home. In the US, the average demand for a home is 920 kwh per month, which amounts to 3,833 Watt panels if you assume 8 hours of usable sunshine and don't take into account your location. At current installation rates that's easily a $9,65 project. If you assume a 25 year useful life, it amounts to a return of 3.3% per annum at 0 cents a kwh not counting the costs of repair, insurance, the inverter, any fees to the utility for net metering if any etc. You would be better off putting $9,65 into a mutual fund until better technology or government incentives came along, in some areas, the government subsidies can make it worth your while. Also, keep in mind that in many areas, the net metering arrangements only deducts the power you've generated from your bill so you would want to size the array to meet your base usage in order to get the most from your investments. So meeting your actual needs would result in a loss on the return as there will be months where your usage is less than your average. In theory, if you put $7,208.69 into a mutual fund expected to return 4.4% per annum then you could withdraw enough to pay each month's power bill for 25 years at $0.0 a kwh and therefore be self sufficient through financial means. You would get more mileage focusing on heating and hot water as heating and hot water is 75% of a home's energy use and can be addressed with lower cost technologies like passive solar and solar thermal panels. You have to put it into perspective, it's an investment and you want a return that's competitive with your investment opportunities.
- Q: The intensity of sunlight at the distance of the Earth's orbit is 380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? Assume that the satellite's attitude control jets keep the panel oriented perpendicular to the incoming sunlight.
- This is pretty much an exercise in knowing units and dimensional analysis. Watts are in Joules/second. So every second a square with the area(meters^2) of meter^2 receives 380 joules from the sun. In your case the square is the solar panel. So find the area of the solar panel in m^2. If you multiply area times intensity you can see that the meters cancel out and you are left with Watts(J/s). Since you want the Joules received in an hour you again multiply by how many seconds are in an hour. Leaving you with joules. What you have now is the total energy, but your solar panel is only 26% efficient, so just multiply by .26 and you will have your energy.
