FAQ

We have organized several common questions for our clients,may help you sincerely:

1). What’s price per watt?

A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.

2). Can you tell me the parameter of your solar panels?

We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.

3). How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

4). How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The perfect time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.


What’s a typical solar panel efficiency rating?

Most solar panels  are around 11-15% efficient, The efficiency rating measures what percentage of sunlight hitting a panel gets turned into electricity that we can use. The higher the efficiency, the less surface area you’ll need in your solar panels. Although the average percentage may sound a little low, you can easily outfit a typical roof with enough power to cover your energy needs.

What are the most efficient solar panels?

In the lab, scientists have developed solar panels that are 40% efficient, or even slightly more than that. But there’s a big difference between the lab and the real world. Manufacturers haven’t yet figured out how to take these experiments and produce economically viable products. Thinking you should wait for new whiz-bang panels is one of the most common solar myths.

Should I choose the most efficient solar panels available?

High efficiency doesn’t mean better, it just means your panels use less space on your roof. Efficiency isn’t usually a critical concern unless you have an unusually small space for your solar panels. The most efficient solar panels cost a little more, so they’re a less common choice.

Factors that affect solar array efficiency include:

 

  • Panel Orientation

In the U.S., your roof ideally should face south, but a quality design can often compensate for other directions.

  • Roof and Panel Pitch

The “pitch” or tilt of your roof can affect the number of hours of sunlight you receive in an average day throughout the year. Large commercial systems have solar tracking systemsthat automatically follow the sun’s tilt through the day. These are expensive, however, and not typically used for residential solar installs.

  • Temperature

Some panels like it hot but most don’t. So, panels typically need to be installed a few inches above the roof with enough air flow to cool them down. Some photovoltaic panels are designed to be more efficient in hotter climates. Hot temperatures can reduce the efficiency of solar panels.

  • Shade

Basically, shade is the enemy of solar panel efficiency. With poor solar design, even a little shade on one panel can shut down energy production on all of your other panels (like a bad bulb in a string of Christmas lights). Before we design a system for your home, we’ll conduct a detailed shading analysis of your roof to reveal its patterns of shade and sunlight throughout the year. Then, our local installation partner conducts another detailed analysis to verify our findings. This is just one of many reasons to work with a highly experienced solar provider like.

Q:What is the current situation and the recent progress space solar cells in China?
The space solar cells is uniquely designed for the power supply for the space, which is very expensive to build and maintain.
Q:Can anybody tell me the power supply of the home solar cell?
In my old place, all I was using was the 50WAT solar cells, which is definitely good and useful for all my daily use.
Q:How can the huge solar cells be applied into the market?
The huge solar cells are more used in the industrial project, which needs more power supply in one time. Without the huge solar cells, it might not be able to work at all.
Q:How to make solar cells in a scientific way?
As far as I can remember, you do need some salt for making solar cells.
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
The process of solar cells' conversion first requires a material which absorbs the solar energy (photon), and then raises an electron to a higher energy state, and then the flow of this high-energy electron to an external circuit. Silicon is one such material that uses such process.
Q:What can be used as the materials for solar cells?
The thin-film absorbers
Q:What is the most commonly used material for solar cells?
Because of the commercialization of solar cells. The variety of solar cells includes monocrystalline silicon solar battery, poly silicon solar cell, non crystalline silicon solar battery, there are also,cadmium, copper indium, etc.
Q:How can I calculate the cost of using solar cells if I put a fully-functional solar system in my house?
Sunrun solar lets you get started for as little as $0 down, but to install it, it will cost you a lot.
Q:I am a purchasing manager for a EPC engineering company, and we are planning to purchasing some 4bb solar cells for one of our project in Taiwan, can I get a quotation online?
I did the purchasing for my client once, and I found out you can get to talk to many sellers if you spend some time searching on alibaba.
Q:Have you ever been to a solar cell power generation station?
I know a company named SUNPOWER is famous for that.
