Our Thanksgiving promotion features three highlighted spending tiers: spend $300+ to save up to 7%, spend $800+ to save up to 10%, or spend $2,000+ to save up to 11%. These percentages reflect the maximum effective savings at each threshold. The promotion uses fixed-dollar discounts rather than a flat percentage off your entire order.

Thanksgiving promotional discounts generally cannot be combined with other discount codes unless explicitly stated. If you have a newsletter, member, or other promotional code, please check which eligible offer provides the best savings at checkout.

Orders are typically processed within 1–3 business days, with standard U.S. delivery estimated at 3–8 business days after shipment. Holiday demand and carrier schedules may cause delays. Tracking information will be emailed once your order ships.

Eligible purchases are subject to our return and warranty policies. Return eligibility and warranty coverage vary by product and circumstances. For assistance, contact services@callsunsolar.com with your order details.

The best solar panel depends on how you plan to use it. Rigid panels are a great option for permanent installations on RVs, cabins, and homes. Flexible panels can work well on certain curved or weight-sensitive surfaces, while portable panels offer convenience for camping and temporary setups.

That depends on your daily energy needs, battery capacity, and available sunlight. A single panel may be sufficient for smaller charging needs, while larger systems or multiple appliances may require additional panels.

Compatibility depends on the specific power station model, not just the brand. Compare its solar input specifications with the panel's electrical ratings, and use the appropriate compatible connection cable or adapter.

Many Callsun panels are suitable for RV and camper applications. Before installation, check the available mounting area, panel dimensions, roof structure, weight limits, and electrical compatibility with your existing system.
