Product Overview

What This Product Is

A 150W monocrystalline solar panel module designed for residential off-grid and hybrid systems. It features 36 solar cells, a maximum power voltage of 17.8Vdc, and a maximum system voltage rating of 1000Vdc. The panel is built for long-term outdoor use with a 25-year transferrable power output warranty and a power tolerance of 0 to +5%. It is suitable for integration into matched solar kits where voltage compatibility and consistent output are required.

Key Benefits

What You Get

150W rated power with a 0 to +5% power tolerance for predictable energy yield
Monocrystalline cells with 18.0% efficiency for high performance in limited space
Maximum system voltage of 1000Vdc allows for longer string lengths without voltage drop

25-year transferrable power output warranty: 90% at 10 years, 80% at 25 years
Dimensions 1480mm x 670mm x 35mm fit standard roof and ground mounting systems

Who It Is For

Buyers and Sites

Solar installers building small residential solar systems
EPC contractors sourcing panels for matched system kits
Homeowners installing a solar array without grid connection
Importers supplying solar components to off-grid markets

Application Scenarios

Where It Is Installed

Residential off-grid homes needing a small but reliable solar input
Hybrid systems where the panel supplements grid or generator supply
Remote cabins or small farm buildings with limited roof space
Replacement of older panels in existing solar arrays with consistent voltage and power

Problems It Solves

What This Removes From the Job

Mismatched panel voltage and system voltage when integrating panels from different suppliers
Uncertain power output due to lack of a verified power tolerance and warranty
Inconsistent panel performance in shaded or variable weather conditions
Difficulty matching panel string voltage to inverter input range without pre-testing

Technical Features

How It Is Built

Monocrystalline silicon cells with 18.0% cell efficiency
36 solar cells connected in series for stable voltage output
Open circuit voltage (Voc) of 21.6Vdc within standard inverter input range
Short circuit current (Isc) of 8.75A for reliable current delivery

Maximum system voltage rated at 1000Vdc for safe string operation
PID resistant and suitable for long-term outdoor exposure
Black frame and tempered glass for durability and aesthetic integration

Materials

What It Is Made Of

Monocrystalline silicon cells with high-efficiency PERC or standard structure
Tempered glass front cover with anti-reflective coating
Black anodised aluminium frame for corrosion resistance
EVA encapsulant and backsheet for moisture and UV protection
MC4 connectors pre-installed on the module for plug-and-play connection

Manufacturing and Preparation

Before It Ships

Panel cell efficiency and power output verified against the 150W rating
Voc and Vmp measured under standard test conditions before packing
MC4 connectors tested for secure connection and insulation
Panel surface inspected for scratches, microcracks or delamination
Packed in protective cardboard or wooden crate for export shipping

Quality Control

Checked Before Packing

Power output checked at 1000W/m² irradiance and 25°C cell temperature
Voc and Isc measured and recorded against the specification table
Visual inspection for surface defects, frame alignment and connector integrity
Encapsulation bond tested for delamination under thermal cycling
Packaging verified to prevent damage during transit

Customisation

What Can Be Changed at Order Stage

Panel color changed from black to blue upon request
Frame material upgraded to stainless steel for coastal or high-salt environments
Connector type changed from MC4 to other compatible types if required

Mounting brackets supplied separately for custom installation needs
Labeling and documentation customized for regional import compliance

Comparison

How It Compares With the Alternatives

Polycrystalline panel	Higher efficiency and better performance in low light, but slightly more expensive
Higher wattage panel	Lower power per unit, but more suitable for small roof areas and lower system voltage requirements
Buying panels from multiple suppliers	Consistent voltage and power output across units, reducing mismatch losses
Panel without warranty	25-year transferrable power output warranty provides long-term reliability assurance
