Q:This is for my science project and i cannot figure it outWe assumed that blue light shining on a solar panel would give off the higher volt reading because it has the shortest wavelength and the highest energy, but it was actually the lowest. Why does this happen? Im very confused And cant find the answer anywhere.... ，thank you!!: I okorder /

Q:Can I add more solar panel let say up to 200 watt and adding two 2 volts battery using the same charges controller and power inverter?: That charge controller is notoriously cheap and burns up easily. If you are going add solar panels, also buy another charge controller to go with them. They can both be connected to the same battery bank. I don't believe the kit comes with batteries, so you would buy whatever size 2V battery bank your power requirements call for. The size of the inverter depends entirely on what you are going to power with it, not the size of the panel array. As long as you are not powering anything that is over the 300W rating, you don't need a new one. Just be sure to check the details of the inverter, is it 300W continuous, or can it handle up to a 300W surge? Also, it's a modified sine wave inverter instead of a pure sine wave inverter, so don't plug any sensitive electronics into it. They may not work, or you may get a buzz or hum from it.

Q:How often do solar panels need to be replaced or repaired roughly? Is it costly to do so?: Maintenance Of Solar Panels

Q:I recently got into solar panels, I have little background in electronics but I have done a little electrical work in the past and just want to make a small 36 cell panel to power a 2v battery that would run my a small tv (9 inch) and PS3 for a few hours every night. I have been looking up on how to do it before I get in over my head and I have a few questions.... After you solder all of the cells together then what? Do you hook all of the rows of cells together somehow? Can you connect them straight to a battery? After you hook to the battery do you hook up a power inverter to get the 2 AC plugs that would be needed? Thanks in advance for any help....: You will have to wire them in such a way that provides the battery with the optimal voltage for it to charge, which on a car 2v battery is around 4v. You said you have some background in electronics so this shouldnt be too difficult. You can connect them straight to the battery yes. Like you said, I believe a power inverter from 2VDC to 0VAC would work just fine. PS3 pulls a lot lot lot of current though so it probably wouldnt last too long. Look up the specs for PS3 and see how many amps it is pulling and purchase your inverter based off of that. I remember trying to run an xbox in my car one time and the inverter I had didnt work because of that. Be careful working with batteries, I had one explode in my face about a month ago.. scariest moment of my life! Good luck!

Q:I'm thinking of these solar panels that people have on their rooftops in domestic properties. I suppose I mean after how long do you break even with respect to just carrying on without them and getting you electricity from the utilities companies? Or answer in any way you think is pertinent. The more info the better.: It's generally stated that it takes 0 years for them to pay for themselves. But the concept of paying for themselves is a primitive concept used by those who do not understand finances. You're still losing money when it pays for itself. A more appropriate analysis would be the Internal Rate of Return calculations, Excel makes this calculation easy. Overall,?solar power?is expensive power and works out about 38 cents per kwh ( proper economic estimates typically place it between 23 cents to 45 cents per kwh ). Some idiot here will insist solar doesn't cost that much per kwh, it does unless you're uneducated in finance. Note, it's also not clear if the energy produced by?solar panels?exceeds the energy required for their manufacture, delivery and installation. It takes a lot of energy to melt silicon and the costs triple if you try to recycle the toxic wastes which is why the panels are made where it's still possible to dispose of the toxic wastes. They could very well be causing more environmental damage then they save. With the Europeans what happens is the feed in tariffs makes the solar panels worthwhile. They still don't really pay for themselves but they allow you to take some of the tax money from your neighbors, a bit of an ethical dilemma really but ethics never stopped Europeans.

Q:Can solar panels be used for powering Wi-Fi networks?: Yes, solar panels can be used to power Wi-Fi networks. Solar panels convert sunlight into electricity, which can then be used to power various devices, including Wi-Fi routers. This allows for the establishment of Wi-Fi networks in remote locations or areas with limited access to electricity grids. Additionally, solar-powered Wi-Fi networks are environmentally friendly and sustainable.

Q:I was just wondering what the minimum and maximm charging voltage and ampere is for li ion batteries. If i connect a solar panel, which only gets enough sunshine to generate voltage, will that still charge the battery, or would i have to series connect solar panels until they together reach 3,7volt?: One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .

Q:What is the difference between monocrystalline and polycrystalline solar panels?: Monocrystalline solar panels are made from a single crystal structure, resulting in higher efficiency and performance but at a higher cost. Polycrystalline solar panels are made from multiple crystal structures, which lowers their efficiency slightly but also reduces their cost.

Q:I need to reduce the average monthly home electricity bill by powering some of the household appliances using solar panels. Can I use a 250 watt solar panel to power a medium sized upright fridge?: Well you might reduce your bills, but you wont get your capital back for many years. Do you have LED lighting, I have, every-time one of my compact flourescent bulbs blew I would replace it with an LED, after two years most of my lighting is LED, a good investment I think. What devices do you have, heating and cooking is better with gas (much cheaper) Think about better insulation for wintertime.

Q:Would like to know if the DIY Solar panel systems can be as efficient as a commercial grade panel.: What kind of panel are you talking about? Solar thermal, as in for hot water/room heating? Or photovoltaic? In the end its a matter of how good your DIY skills are and from what level of DIY you are talking about. eg, if you are buying the panels and installing them yourself, then there should be no difference. If you are fabricating the panels then you better be good at what you do. Creating photovoltaic cells is not a simple task. Soldering purchased cells together to create panels is tricky as they are easily damaged. Efficiency should not be a problem, but finish might be as well as robustness. It would be safer to buy complete panels and just mount them yourself and set up the batteries ans switch gear. But use good gear and follow instructions very carefully. With thermal panels you might not get the same levels of efficiency by using cheaper materials, std glass instead of non reflective for instance, but if space is not an issue, then you can get more heat out by going bigger and still save overall.
