ABOUT US

We are a high-tech group wich specializes in solar products design,research, manufacture, sales,solar projects design and installation. 

Our present annual capacity is 6 million for wafer, 60MWp for solar cells,200MWp for solar modules and one hundred thousand for solar applications. It is expected that the annual capacity of 2012 will be up to 30 million for wafer, 300MWp for solar cells, 1000MW for solar modules and 2 million for solar applications. 


INTRODUCTION

This installation Manual contains essential information for the electrical and mechanical installation that your must know before installing CUSTOMER PV modules. This also contains safety information you need to be familiar with .All the information described in this manual are the intellectual property of CNBM and based on the technologies and experiences that have been acquired and accumulated in the long history of CUSTOMER. This document does not constitute a warranty, expressed or implied.

CUSTOMER does not assume responsibility and expressly disclaims liability for loss, damage, or expense arising out of in anyway connected with installation, operation, use or maintenance of the PV modules. No responsibility is assumed by CUSTOMER for any infringement of patents or other rights of third parties that may result from use of PV module.

CUSTOMER reserves the right to make changes to the product, specifications or installation manual without prior notice.

 

WIRING

To ensure proper system operation to maintain your warranty, observe the correct cable connection polarity(Figures 1&2) when connecting the modules to a battery or to other modules. If not connected correctly, the bypass diode could be destroyed.

PV modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative of the next module. Figure shows modules connected in series .

Q:how much money can I make a year for the electricy I sell from a solar panel?
Ultimately it depends on your utility and the country you're in. In countries like Germany, Spain and the UK, the utilities will pay a higher price for the power you produce then what they sell it to you at. Otherwise, in countries that don't have such arrangements, net metering is best where what you produce is discounted from the amount you buy per month therefore so long as you produce less than you use, you get the full retail rate, otherwise you may get only half the retail rate with some utilities. Obviously, the solar panels are rated and won't produce much more than the rated power, a 4 foot by 2 foot panel would usually be rated at 00 watts but in most situations will produce about 80 watts and would probably cost about $500 US installed. If you assume 8 hours of usable sunshine a day, 70% sunny days, a 25 year service life, monthly billing and 0 cents a kilo watt hour retail rate, you can expect at most a -.67% per annum return on your investment, that's a negative sign out front. Basically without any subsidies, you will lose money on the panel, sure you're get some money every month, about $.34 per month for that 00 watt panel but it won't make back it's money at at a rate of 0.0 per kwh. With subsidies it might be a good investment but it's still not a good deal without subsidies.
Q:how can i build a solar panel?
Have okorder.com . This can surely guide anyone!

Q:how do I become a solar panel contractor?
Contact some solar panel manufacturers or distributors. I recently started working for a solar panel dealer and they can't find enough qualified workers to install here in the US. Desperately seeking electricians but don't pay well.
Q:Maintenance for solar panels....?
All panels should be cleaned to function best. Brush or wash off dirt and leaves. They should be checked for structural integrity and lack of rust. Solar Thermal panels should be checked for signs of leaks and/or discharge from pressure relief valves. Solar Photovoltaic should be checked for electrical function and grounding.
Q:How do you connect solar panel?
You need a charger Controller but 55 watt panel is not a whole lot of power. So yes you can buy a very good one but it will cost a lot more. For a 55 watt panel you only need a 4 to 7 amp controller. But why not buy a 0 amp so you can add a second solar panel etc... A PWM (Pulse Width Modulated) is the cheapest and most robust type MPPT (Maximum Power Point Tracking) These controllers actually detect the optimum operating voltage and amperage of the solar array and match that with the battery bank. The result is additional 5-30% more power out of your array versus a PWM controller So unless you have a system over 200 watt the PWM works very good I have two of the PWM myself
Q:SOLAR PANEL ENERGY! HOW DOES IT WORK?
This forum of solar panel is for electric You also get a diffrent type of solar panel this type of panel has a liquid that flows through it and is heated up by the same photovoltaic cells but is ran through the water tank to keep the water warm
Q:Can solar panels be connected directly to motor?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
Q:A question about solar panel?

Q:Increase Solar Panel Efficiency?
If you have a way to keep silicon panels cool, that really helps. On a hot summer day, our array was down 20% in production. I sprayed a hose to wash the panels, and for a few minutes, the power spiked to 20% ABOVE normal. The usual thing to do is mount the panels exposed to the wind if you can, or at least 8 off the roof otherwise. A few lucky souls with access to free stream water on their property have been known to use water cooling under their panels.
