Product Overview

What This Product Is

A 250W monocrystalline solar panel designed for residential off-grid and hybrid solar systems. It has 60 solar cells, a maximum power voltage of 30.85V, and a maximum system voltage of 1000V. 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 rooftop and ground mounting in residential applications.

Key Benefits

What You Get

250W rated power with 0 to +5% power tolerance for predictable energy yield
Monocrystalline cells with 18.33% efficiency for high energy density
Open circuit voltage of 36.92V allows for string configuration in cold climates

Maximum system voltage of 1000V supports larger array designs
25 year transferrable power output warranty: 10 years at 90%, 25 years at 80%

Who It Is For

Buyers and Sites

Solar installers building residential solar systems with matched components
Homeowners installing a solar system for self-consumption or backup power
EPC contractors sourcing panels for small-scale residential projects
Importers supplying solar panels to markets with weak or unstable grid access

Application Scenarios

Where It Is Installed

Residential rooftop installation in areas with moderate to high solar irradiance
Off-grid home power system where consistent energy generation is required
Hybrid solar system with battery backup for homes with intermittent grid supply
Ground-mounted solar array for homes with limited roof space or shading issues

Problems It Solves

What This Removes From the Job

Panels with mismatched voltage or power output that reduce system efficiency
Lack of long-term warranty on panel performance leading to financial risk
Inconsistent cell efficiency across batches causing uneven power generation
Insufficient system voltage rating that limits string length and design flexibility

Comparison

How It Compares With the Alternatives

Polycrystalline panel	Higher efficiency and better performance in low light, but slightly more expensive
300W panel	Lower power output but more suitable for smaller systems or limited roof space
Thin film panel	Lower efficiency and higher degradation rate, but lighter and flexible
Grid-tie panel	Same power output but designed for higher system voltage and different safety standards
