In summary, JA Solar’s diverse portfolio underscores its commitment to not just harnessing solar energy but ensuring its efficient storage and use.
Understanding the Cost of JA Solar Panels
Determining the precise cost of JA Solar panels for your home can be a bit complex, given the multitude of factors at play. Your solar installation is unique and influenced by aspects like the system’s size, your house’s dimensions, your monthly power usage, roof shading, and even regional and installer variations.
However, general observations suggest that JA Solar panels are competitively priced, often hovering around $2.70 per watt. While the national median price for solar panels stands at approximately $2.66 per watt, JA’s peers with similar efficiency benchmarks, such as REC, LONGi, Trina Solar, and Canadian Solar, typically have prices closer to $3.00 per watt.
To paint a clearer picture, consider an average U.S. solar system, which is around 9.5 kilowatts (kW). Opting for a brand priced at $3.00 per watt would set you back about $28,500 before applying any incentives. However, selecting JA panels for the same system size could reduce your bill to roughly $25,650, saving nearly $3,000.
Financing Your JA Solar Panels
JA Solar primarily operates as a manufacturing entity, without a dedicated installation division. This approach aligns with the broader solar sector, with a few exceptions, for instance, Maxeon/SunPower.
Therefore, your financing avenues for procuring JA Solar panels will largely depend on your chosen solar installation firm. While some outfits might be restricted to upfront cash payments and solar loans, others could offer flexible solar leases and power purchase agreements (PPAs).
If feasible, an outright cash purchase is advisable. While it requires full payment upfront, it grants you immediate ownership of your panels. This translates to quicker returns on investment and maximized long-term solar benefits. On the other hand, loans, due to interest components, might marginally decrease the advantages but still serve as a decent alternative.
The affordability of JA panels makes cash purchases more attainable compared to several other brands.
It’s worth noting that options like solar leases and PPAs, although eliminating upfront costs, don’t transfer panel ownership to you. This means forgoing benefits like the federal investment tax credit (ITC). They also tend to offer limited long-term savings and might introduce complexities when you plan to sell your property.
Assessing JA Solar Panel Warranty: Is It Worth It?
Despite their competitive pricing, JA Solar panels sometimes might not offer the reliability and durability you could expect from pricier alternatives.
A significant point to consider is the equipment warranty. JA Solar provides a 12-year equipment warranty on its panels, which is notably shorter than the standard industry duration of 25 years. To give context, many of JA Solar’s competitors, such as REC, Trina, QCells, Jinko Solar, and Canadian Solar, equip their products with a comprehensive 25-year warranty, covering equipment and manufacturing defects.
This discrepancy implies that although you might save initially with JA Solar, potential issues surfacing post the 12-year mark could lead to unexpected expenses in the longer run.
Regarding performance guarantees, JA panels offer either a 25-year or a 30-year assurance. For instance, certain models like the JAM54S31 MR from the DeepBlue 3.0 Light series assure a 25-year warranty with a maximum annual efficiency drop of 0.55%. This translates to a slightly below-par 86.25% efficiency at the close of the warranty duration.
Contrastingly, some Pro models in the DeepBlue 3.0 range record a slightly better yearly degradation rate of 0.45%. A standout in the performance warranty department is the DeepBlue 4.0x JAM54D41 GB, promising a mere 1% efficiency decrease in its inaugural year and a subsequent annual drop capped at 0.4%.
For a broader industry perspective, the general average stands at a 2.5% efficiency decline in the initial year, followed by a consistent 0.4% yearly dip, resulting in a cumulative efficiency reduction of 12.1% over the span. Brands like Maxeon, for example, have some of the industry’s most impressive degradation rates, ensuring a commendable 92% of their initial efficiency even after a quarter-century.
