How much does the SunPower solar battery cost?
SunPower solar battery costs vary by model and order quantity. Small 1W PET cells start at ¥12.00/unit (1000+ pieces), while 100W flexible panels range from ¥280–350/unit for bulk orders. High-efficiency 22.6% photovoltaic components cost ¥12.50–15.00 per cell at wholesale volumes. Semi-flexible marine/roof panels are priced higher at ¥1264.99/sheet retail. Volume discounts apply—5000+ units reduce 1W cells to ¥11.00 (-8.3%).

What determines SunPower solar pricing tiers?
SunPower pricing depends on cell efficiency (22.6% vs standard 20%), form factor (rigid vs semi-flexible), and order volume. Bulk purchases of 1000+ units unlock 4–20% discounts. Pro Tip: Verify IEC 61215 certification for true efficiency claims—some listings inflate specs.
Technical specifications like open-circuit voltage (7.139V) and short-circuit current (0.09–5.5A) impact cost. Higher 100W models with 540mm dimensions require advanced PET encapsulation, adding 15–20% to baseline pricing. For example, a 500-unit order of 100W flexible panels drops from ¥350 to ¥300/unit. But how do logistics affect final costs? Shipping from Shenzhen adds ¥12–50 depending on delivery speed.
How do SunPower models compare?
| Model | Power | Price/Unit |
|---|---|---|
| SP-100W | 100W | ¥280–350 |
| XXR-133 | 6.05V | ¥15.00 |
| Marine 225W | 225W | ¥1264.99 |
Beyond wattage, consider dimensions—1050×540mm 100W panels need 2× more space than 106.5×60.5mm 1W cells. Practically speaking, 22.6% efficiency cells yield 30% more daily kWh than standard 18% models. Why pay extra? High-efficiency units pay off in space-constrained RV/marine installations.

FAQs
Do prices include solar charge controllers?
No—controllers sold separately. MPPT units add ¥200–800 depending on amp rating (5–30A).
Can I mix SunPower cell efficiencies?
Not advised—22.6% and 20% cells in parallel create imbalance, reducing output by 15–25%.
