3. Q: Do you provide free sample?
A: Usually we do not offer free sample

4. Q: Could you print our company LOGO on the nameplate and package?

A: Yes, we can do that.

Q: how efficient are flexible solar panels?: I don't have a number, but in general, no one uses a flexible panel unless they are compelled to. The efficiency is lower, and my experience is that they don't last. I had one a few years ago, and it lasted less than 2 years. My rigid panels came with a 25-year performance warranty, and are still working great after 7 years.

Q: looking for a solar panel to charge my laptop on the road, macbook is 60 watt 6.v 3.5a, what should i be looking for in a solar panel?: Well that's a good idea,,,here's what ya need..First you need an array that will overcome the drain effect created by the in use or sleeping laptop...that is best solved by averaging out the real use of the machine in terms of watt/minutes...If you check your transformer you'll see it has a capacity which you have cited however the true use of the computer is about 40-50 percent of that in watt/minutes..but only while your using it and when in the sleep mode the watt/minute value drops even more to about 5%.... So if your actual use consists of 2 hours of use per day at 50% and 2 hours at 5% percent the actual wattage draw is only averaged out at 34watts/minute. optimally your panel should supply all your power from its photovoltaic conversion ,but in the real world application the panel only recharges ,over a period of time, the used power. So if you had a 5 watt (@ 2vdc) panel working 480 minutes and used up 35 x2=700 and 9 x2=8 for a total of 78 watts you would have 5 x 480 = 7200 watts input and a parasitic load of 78 watts in the two hours...well within the recharge state required.. For a little safety I would permanently wire a cigarette lighter type plug to the end of the panel this will keep the polarity correct and serve as a quick disconnet means...Also add a fuse at .5 amp... a good place to get these are on the internet....some are very expensive some a very cheap --go for a middle of the roader...Have a good one from the E...

Q: What is the impact of roof pitch on solar panels' efficiency?: The impact of roof pitch on solar panels' efficiency is significant. A steeper roof pitch allows for better solar panel orientation towards the sun, maximizing the amount of sunlight they can capture. This leads to increased energy production and higher overall efficiency. However, a flatter roof pitch can still be suitable for solar panels, as long as they are properly tilted or mounted to optimize sun exposure. Ultimately, the ideal roof pitch for solar panels depends on factors such as geographic location, climate, and the specific solar panel technology being used.

Q: So how does a solar panel work? Where does the energy get stored in? How much does one cost for a small 2 family home? How much money would we save on electricity?: In the short, a solar panel is composed of many solar cells...all tied together and in some sort of a frame for mounting. When energy from the sun hits it, it creates a reaction which can feed electricity through leads to a converter system which takes the Direct Current power and converts it into Alternating Current. If you rewire your house for DC products I suppoes you wo'nt need the converter. but most of these systems are retro-fits. Batteries provide back up source to the system when the sun goes down. So solar is converted to electricity through the panel, which goes to your solar system which both provides power to the house and to recharge batteries. The batteries take over when the sun is down. So you will need to know how much battery capacity you need by calculating the Amp hour rating of your applicances that you normally use at night like Microwave, TV, radio, refrigerator, etc. For some depending on the appliance....water heater (if electric) or stove) then you need to figure out how many panels you need to provide your normal daily energy use, figure out how many batteries you need, set up a distribution system that gives you what you need where you want it and wa la. Once done, you will be off the grid and paying nothing from the electrical utility. Some places due to deregulations allow you to sell excess power to local utilities too, but those systems need to meet tight standards.

Q: I am designing a solar panel but i need to have maximum power output.How can i optimize the equation for power Total power=voltage * current to get maximum power.: first place the panel so it is at right angles to the solar rays. Make sure none of the panel has any shade whatsoever. For best results use motor drives to keep it in that position as the sun moves across the sky. For overall maximum versus time, you need to be near the equator. Solar cells have a high internal resistance, so for maximum power transfer, you need a load of that same resistance. A good charge controller will use DC-DC converters to provide that load. .

Q: Where can I find the info (sites) that clearly gives the anatomy of a solar panel?Likewise, I want to know where can I find (sites) the solar panel that produces 3.75 v? Thank you very much!!!: You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.

Q: I bought a pack of OEM mini solar panels that produce 4.2v and 22mA and I was just wondering how many LED's I could hook up to one mini solar panel? I currently have one green LED with a resistor on the one panel but was wondering how many I could possibly run off of one panel?: Typically LED's run off low voltage and 20mA or so of power (it depends what kind of led you have). That being said if one of your solar panels only provides 22mA of power then your circuit would have to be a series circuit for you to connect more than one. In a series circuit the current supplied of 22mA will go through each LED whereas a parallel circuit the current would be divided for each subsequential led. So in your case i can see you getting away with 3 or so led's before the voltage drop across each led will cause the voltage to be insufficient enough to drive anymore. Keep in mind the LED's will turn on but the first one will be bright then next one not as bright and so on. If you opted out and bought a solar panel with 200mA and 4V you could wire the led's in parallel and get 0 led's to turn on with the same brightness or intensity. Hoped that helped!

Q: Can solar panels be installed on data centers or IT facilities?: Yes, solar panels can be installed on data centers or IT facilities. In fact, many data centers and IT facilities are increasingly adopting solar energy as a sustainable and cost-effective power source. Solar panels can be installed on rooftops or in open areas surrounding the facility to generate clean electricity and reduce their reliance on traditional grid power.
