Characteristics of Polycrystalline 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. .

Thanks for your time.
- Q: Why would someone use a solar panel? Does it have to do with the economy right now, global warming, or what?
- solar cell is a solar cell solar panel are many solar cells.... Typically people refer to a single solar panel as a solar panel, even though they should be reffering to it as a solar cell. A solar panel is a panel of solar cells working in conjunction with each other. I hope that makes sense it is just the incorrect terminology people always use.
- Q: In terms of efficiency and cost, what is the best solar panel. I am limited in the number of panels I can put up (probably 6-8) so they must be efficient, but cost is important also.What about these panels that can collect a wider range of light frequency?
- You have to decide which is more important to you, cost or efficiency. The most efficient solar panels that are commercially available cost more than twice as much per square foot than the cheapest ones. Ultimately, I believe that the cost per watt was actually better on the cheaper, least efficient panels, but then you need a lot of square footage in order to generate any substantial power. So it comes down to what you have more of, space or money. The new panels that collect a wider range of light are not currently available commercially, and when they are I am sure that they will be expensive. I have read the research but have not heard of anyone mass producing them yet.
- Q: I need a new roof soon and I was wondering what the difference in cost would be from a standard shingle roof to a roof including solar panels. Does anyone know the cost difference?
- The solar panels are very expensive to provide much power. If u go that way do not skimp on the support as a high wind will blow them away. In Ecuador I put in a remote site for communications. It was working good when a Strong wind blew $0.000 worth of solar panels all over the jungle.
- Q: Can solar panels be installed on a gas station or fueling facility?
- Yes, solar panels can be installed on a gas station or fueling facility. In fact, many gas stations and fueling facilities have started installing solar panels to generate renewable energy to power their operations. This not only helps reduce their carbon footprint but also cuts down on electricity costs.
- Q: It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.
- you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
- Q: Can solar panels be installed on multi-story buildings?
- Yes, solar panels can be installed on multi-story buildings. In fact, multi-story buildings are often ideal for solar panel installations as they have a larger surface area to accommodate more panels. Additionally, the height of the building can provide better exposure to sunlight throughout the day.
- Q: I own a townhome in the Phoenix area (my power company's SRP, if that makes a difference). Phoenix is a great place for solar. I could probably save money, in the long term, if I got some solar panels.But I am currently extremely broke, so I can't buy solar panels unless I will more or less immediately be paying no more than I am now per month, with little or nothing down. And most of the solar leasing places won't work with me, because (as is common for townhomes) I don't technically own my roof. I have permission to put things on it, but the property management people (or whoever actually owns my roof) won't sign the lease or whatever.Anyone know of either a way to buy solar panels without paying significantly more per month than I already do for electricity, or a solar leasing company that can work with the restrictions I have?
- There are companies who would install solar panels on your roof for no cost. The catch is that they get the power generated for the first 20 years which is the useful life of the panels then you get what's left of the obsolete panels, meanwhile you're required to purchase your power from them at allegedly reduced rates but there is no guarantee that they would remain reduced versus the market once they have you locked in. It's like how the cell phone companies will give you a free cell phone if you sign a contract. Keep in mind that once you've factored in the installation costs and the useful life of the panels, the effective costs of solar photovoltaic energy is about 23 cents to 43 cents a kwh while grid power is about 5 cents per kwh to the consumer, 3 cents per kwh to the utilities for coal generation. It's just that so few people understand how to project an initial capital expense with periodic future returns through discounted cash flow, hence people think solar power is free out of ignorance. Without government incentives, there are no economic benefits to solar and most solar installers structure the sales such that they gain the economic benefit instead of the consumer who is often ignorant of how to calculate the financials.
- Q: I want to purchase some or one solar panel for my home. I don't know where to buy them from. I've loooked online and if i could buy them online that would be best, but if you knew of a website that has good prices than that would be great!Thanks

- Q: I have two solar panels and I have measured that they produce V by themselves. I am trying to generate .5V, but whenever I hook them up in parallel I get something like .02V. What it happening?
- . You want series, not parallel. (Add the voltages. Coonect '+' of the first to '-' of the next, and take your feed from the extreme ends.) 2. if you parallel them and you get less voltage than one alone, you got your polarity crossed up and are reading the difference between them.
