Characteristics of Solar Panel

I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water

IV AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease.

VII Good performance of preventing from atrocious weather such as wind and hails.

VIII Resisting moisture and etching effectively, not effected by geology.

Currently,We have 250w-300w solar panel stocks in Both West and East Coasts made in Vietnam,India,Korea,Malaysia and Japan.Meanwhile,we also arrange production line in Wisconsin,USA.If you're interested,please contact us soon.

Thanks for your time.

Q:Solar Battery System?
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
Q:Solar Panel and Wind Power?
I live in the Southwest where the sun shines almost every day. I got a quote for Solar system to produce about enough to cover my annual usage. My annual average electrical usage costs about $2300, or about $90/MO. The system costs around $30,000 but I can get rebates and some of your tax dollars in subsidies to bring my cost down to under $20,000. I can borrow $20,000 for 3 years at 7% and pay $95/MO, so in 3 years I will have the system paid for. As you can see, I don't start Saving any money for a long time. Maybe the rates will go up in later years which will help, but My friends that have solar systems tell me things like controllers go bad over time and they cost like $3000. Will it ever pay for itself? Maybe. Please note. This still does not get me off the grid. This system will not support things like an electric stove, air conditioning, Pool pump running, etc. so I still need the grid for when these operate and my usage peaks. If I installed a system that would totally support everything 24/7 the cost would be astronomical. If you live in the east, midwest, or NW where you have cloudy days, your economic calculations will be much less favorable I would think, unless your power costs are much higher than mine..
Q:Using a solar panel to make energy?
Small solar panels produce almost no power that matters to anything. A whole square meter may produce 80 Watts when facing the noon sun in Arizona. take that down to 28 Watts in Erie Pa. The 80 Watts can charge a 2 volt battery at about 8 amps times 6 hours, or 48 Amp hours per day in Arizona or perhaps 5 amp hours/day in Erie. The amount of energy you can save declines as the battery is more charged so you need to use up the power stored before you have more to save. To do that charging you need a circuit that will carry 8 amps, including a voltage regulator. So, if your circuit can stand 20 amps the person in Arizona can run 2 square meters of panel. It may seem strange but the same is true for the person in Erie. The person in Erie has to allow for the maximum output of the panel, not the expected average. The person in Erie will occasionally have really clear skies and put out maximum rated amps. The amperage that the batteries can put out at maximum should not be used. That will destroy the battery. One puts a breaker on each output circuit to protect the circuit and a breaker that limits battery output to 20 amps based on a battery rated at 800 amps. That 800 amps is surge capacity. One or two panels does not really justify having this capacity for battery and circuitry. I can think of using it to provide an emergency LED lighting system.
Q:Is there a free solar panel program for veterans?
It varies from state to state.
Q:what is the cost of getting km sq of solar panels?
As okorder.com/ They are working on a reactor that makes diesel and electricity concurrently out of coal, biomass or possibly garbage in a non-polluting process.
Q:What is the working principle of solar panels?
the inorganic salts such as gallium arsenide Ⅲ-Ⅴ compounds, cadmium sulfide, copper indium selenium and other multi-compounds as the material of the battery;
Q:Why do people use solar panels?
I doubt the immediate economy has much to do with it. Solar panels require long-term investment, so in hard times, someone having trouble making ends meet is not going to be buying solar panels, when they could be buying food. It's like if someone has a gas guzzler, if they get laid off, they're not going to spend their savings on a new, fuel efficient car, even if it saves money in the long term. However, it's generally the more wealthy that install solar, and they're not impacted as much by a slow economy. Human nature being what it is, I doubt many people install solar to save the planet. There will be some, but I suspect most are interested in the long-term financial savings. I'm kind of unusual, in that our panels are break-even financially at best. The main reason I put them up was for the fun of learning and doing it.
Q:Solar panels?
There are RV solar panels but they are mostly for extending the life of the batteries, you should still bring a generator. There are marine solar panels and wind turbines which are larger but many sailing yachts are larger too.
