Solar Panel Assessment: ZNShine Models (Year 2024)
ZNShine, a Tier 1 solar panel manufacturer based in China, has introduced double-glass solar panels that offer a range of benefits for residential and commercial solar installations. These panels incorporate graphene into their solar cells, boosting efficiency and providing resistance to environmental factors.
Benefits of Double-Glass Solar Panels
Increased Durability and Lifespan
Double-glass panels use tempered glass on both front and back sides, which improves structural robustness and weather resistance, leading to reduced degradation. Premium panels with advanced technology, like those of Znshine, may lose only about 5% efficiency over 25 years, compared to roughly 10% for cheaper, conventional modules. Double-glass construction protects against moisture and mechanical damage better than standard single-glass panels.
Better Power Output and Efficiency
Znshine's double-glass bifacial panels, such as the 670W model with 21.57% efficiency, leverage bifacial technology that can capture sunlight from both sides, boosting energy yield over time. The double-glass design complements this by ensuring stability and resistance to environmental wear.
Improved Heat Dissipation
Double-glass panels tend to have better temperature performance due to the tempered glass layers dissipating heat more effectively, helping maintain efficiency during hot conditions.
Lower Levelized Cost of Energy (LCOE)
Although initial costs may be higher, the longer lifespan and increased energy output of double-glass bifacial panels can reduce the overall cost per kWh of generated electricity across the system lifetime.
Drawbacks of Double-Glass Solar Panels
Higher Upfront Cost and Weight
Double-glass panels are usually heavier and more expensive than standard single-glass panels. This can increase installation complexity and costs, requiring sturdier mounting systems.
Installation Considerations
Their increased weight and thickness may limit suitability on roofs that cannot support the load or in situations where easier handling is preferred. This might also affect the choice of racking and mounting methods, possibly requiring additional planning and expense.
Uncertainty in Bifacial Performance
While bifacial double-glass panels offer higher energy yields, actual gains depend on site-specific factors like ground reflectivity, tilt angle, and mounting height. Lack of standardized testing and variability in performance estimation can make energy yield predictions and financial planning less certain.
In summary, ZNShine's double-glass solar panels provide long-term reliability, better energy yield, and reduced degradation, making them attractive for durable, high-performance solar installations. However, higher initial investment and installation requirements should be considered, especially depending on site constraints and project budgets.
At 8MSolar, a team of solar experts is available to help with installing a solar system and finding the best solar panel fit for a home. ZNShine Solar panels are priced at an average of about $14,000 after solar tax incentives, which is slightly below the industry's standard. ZNShine produces monocrystalline and polycrystalline solar panels suitable for residential, commercial, and large-scale solar projects.
The top three picks for household ZNShine solar panel models are the ZXM8-SP120 Series, ZXM6-NHLD120 Series, and ZXM6-NHLD132 Series. These models offer power ratings ranging from 360 W to 415 W, which is competitive with most residential solar panels on the market (370 W to 400 W). Additionally, the ZXM8-SP120 Series comes with a 25-year performance warranty, while the ZXM6-NHLD120 Series and the ZXM6-NHLD132 Series offer a 30-year performance warranty.
ZNShine Solar panels use monocrystalline half-cut PERC cells, which are known for fewer resistive losses and better conversion of sunlight into electricity. The performance warranties for ZNShine panels guarantee that the panels will degrade no more than 2.5% in the first year and no more than 0.55% annually (ZXM8-SP120 Series), or no more than 2.5% in the first year and no more than 0.5% per year after that (ZXM6-NHLD120 Series and ZXM6-NHLD132 Series).
It is important to note that any significant drops in production not linked to environmental factors should be addressed with the solar installer. The warranties for ZNShine panels are based on Standard Test Conditions (STC).
ZNShine is recognized as a Tier 1 solar panel brand by BloombergNEF. Many ZNShine commercial offerings feature a bifacial design, capturing reflected sunlight and increasing electricity production. ZNShine's solar panels have efficiency levels starting at 19.76% and reaching up to 21.07%, which is higher than the industry standard of 17% to 19%.
