- High efficiency, multicrystalline silicon solar cells with high transmission and textured glass deliver a module effi ciency of up to 16.0%,minimizing installation costs and maximizing the kWh output of your

system per unit area.

- Tight positive power tolerance of 0W to +5W ensures you receive modules at or above nameplate power and contributes to minimizing module mismatch losses leading to improved system yield.

- Top ranking in the “TÜV Rheinland Energy Yield Test” 


FAQ:What's your products warranty?

No less than 90% within 10yrs and no less than 80% within 25yrs.

FAQ:What's the power range can you supply?

We can supply from 5W to 315W solar panels.

FAQ: Can you design the solar system?

Yes, We can supply the battery and controller/inverter for your system with the solar panels together.

FAQ:How much Power can I expect to get from my Solar PV’s?

Typically an installed 1kWpk array will produce 800kWh/year. 2kWpk will produce 1600kWh/year and so on.

Why are PVs rated in kWpk rather then kilowatts?


kWpk means the power expected to be generated under the comparatively ideal conditions known as STC. In other words, a 100Wp panel will produce a maximum of 100W in peak (STC) conditions - this is equivalent to a bright sunny midsummer day in the UK.

How can I connect my Solar PV system to the grid?

You will need to use a grid-tie inverter. If you wish to get paid for the electricity you produce, you will need to ensure a G83-certified inverter is used and that it is installed by a Microgeneration Certification Scheme member whose membership number will need to be provided to your electricity supplier.


How much will I get paid for the electricity I feed into the grid?

If you install a qualifying small system (1-4kWpk) in the UK before October 2012 you will get paid 16 pence for every kWh you generate regardless of whether you use it yourself or export it to other users. This is a generation tariff or feed in tariff. It will go up each year in line with inflation. If you also use the electricity you have generated this means you do not have to buy it from the electricity company and so you will save around 11-15p per kWh at todays prices (Prices subject to change of course). Energy you generate but don't use yourself, i.e. you export it to the electricity company, will attract another payment to you of 4.5p per kWh. This payment is also index linked to the RPI so it will increase in line with inflation.

Is it true that I can get my electricity meter can spin backwards?

Not usually, nor is it legal to do this. The very old meters may cause this to happen however the company installing your PV will advise you if you need to ask for a meter replacement from the company supplying your electricity. This is usually free of charge.

Q:How much does a solar cell cost?
Figuring out exactly the cost of the solar system you have can take a little detective work.
Q:Is it complicated to make a solar cell work well?
It is quite complicated to make the sun power generate the power we need.
Q:Where can I help my company to buy the 3 Busbar Solar Cell for our project?
Maybe you would like to check this out; Solarworld Brands Mono 3-Busbar Solar Cell Made in Germany. Is this what you are looking for?
Q:How does a solar cell raise industrial efficiency?
A solar cell provides long-lasting electricity which is vital in factories, that's how it raises efficiency.
Q:Is there any easy way to make a solar cell? I want to make a DIY solar cell with my child at home.
I sent a private message to you about my personal experience of diy solar cell.
Q:Are bulk solar cells better than the normal solar cells?
Bulk solar cells are not absolutely better than normal solar cells, it is decided by what kind of material.
Q:How's the feedback of using 260 watt photovoltaic solar panel? Anybody ever used that?
The 260 watt photovoltaic solar panel is very normally used in the market, and the feedback is not bad based on its quality.
Q:Is it possible to learn how to make solar cells by yourself?
I did that when I was 15 years old, and I succeeded!
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?
You can check our product, here are the product details for your information: Mono Solar Cell, 4BB:6x6 inch (156mm*156mm)
Q:Why and what is the low efficiency solar cell?
The technical problems will cause the low efficienct of the solar cells, including solar and thermal energy, solar cells are now either absorb light energy, or absorb heat, there is little light and heat absorbed together.
