1.Structure of Solar Module Description

Solar panel refers either to a solar hot water panel, a common type of a solar thermal collector, or to one or more solar photovoltaics (PV) modules, electrically connected and mounted on a supporting structure.

A PV module is a packaged, connected assembly of typically 6×10 solar cells. Solar PV panels constitute the solar array of a photovoltaic systemthat generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

2.Main Features of the Solar Module

 1).High conversion efficiencies resulting in superior power output performance.

 2).Outstanding power output even in low light or high temperature conditions

 3).Optimized design for ease of soldering and lamination

 4).Long-term stability,reliability and performance

Specification of  Solar Polycrystalline(270W-290W)

CNBM Solar photovoltaic (PV)module is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array.Poly- or multicrystalline silicon(poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified. Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient. US DOE data shows that there were a higher number of multicrystalline sales than monocrystalline silicon sales.



3.Characteristics of Polycrystalline Silicon 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.

IX.The certificate issued by international authority: UL, TUV, IEC, VDE, CE.



1.    Always wear protective head gear, insulating gloves and safety shoes (with rubber soles).

2.    Keep the PV module packed in the carton until installation.

3.    Do not touch the PV module unnecessarily during installation. The glass surface and the frames get hot. There is a risk of burn, or you may collapse because of electric shock.

4.    Do not work under rain, snow or windy conditions.

5.    Use insulated tools

6.    Do not use wet tools

7.    Do not drop tools or hard objects on PV modules

8.    When installing PV modules far above ground, do not drop any object(e.g. PV module or tools).

9.    Make sure flammable gases are not generated near the installation site.

10.  Completely cover the PV module surface with an opaque material during PV module installation and wiring.

11.  Plug in the connector tight and ensure the wiring work.

12.  Due to the risk of electrical shock, do not perform any work if the terminals of PV module are wet.

13.  Do not touch the terminal box and the end of output cable ends ( connectors) with bare hands during installation or under sunlight, regardless of whether the PV module is connected to or disconnected from the system.

14.  Do not unplug the connector if the system circuit is connected to a load.

15.  Do not stamp on the glass at work. There is a risk of injury or electric shock if glass is broken.

16.  Do not work alone (always work as a team of 2 or more people).

17.  Wear a safety belt if working far above the ground.

18.  Do not wear metallic jewelry which can cause electric shock during installation.

19.  Do not damage the surrounding PV modules or mounting structure when replacing a PV module.

20.  Bind cables by the insulation locks. Drooping down of cables from the terminal  box could possibly cause various problems such as animal biting electricity leakage in puddle.
