What is your Return Policy?

At Northgrid Supply, we want every customer to shop with confidence. If something doesn’t go as planned, we’ve made returns and refunds simple and fair. Here’s how it works:

1. Return Window

You can request a return within 30 days of receiving your order. Unfortunately, we’re unable to accept returns after that time frame.

2. Who Pays for Return Shipping?

  • If your item arrives damaged, defective, or incorrect, we’ll cover the return shipping cost.
  • If you’re returning an item because you changed your mind, you’ll be responsible for return shipping fees.

3. Damaged or Defective Items

Received something broken or not working properly? Contact us within 30 days. We’ll provide a prepaid return label and once the item is returned and inspected, we’ll issue either a full refund or a replacement—including any original shipping costs.

4. Changed Your Mind?

If you no longer want the item, you can return it within 30 days—as long as it's unused, in its original packaging, and in resellable condition. You’ll need to handle the return shipping, and once we receive and inspect it, we’ll refund the product cost (excluding shipping).

5. Refund Processing

Once we receive and approve your return, we’ll send a confirmation email and issue a refund to your original payment method within 7 business days. Please allow additional time for banks or credit card companies to process and reflect the refund.

If it’s been over 10 business days since your refund was approved and you still don’t see it, contact us at support@northgridsupply.com and we’ll look into it immediately.

6. Restocking Fees

In some cases, a restocking fee may apply depending on the item and return reason. If applicable, we’ll clearly communicate this during your return request process.

This 335-watt, 24-volt solar panel is designed for grid-tied and off-grid solar installations serving residential, commercial, agricultural, RV, marine, cabin, homestead, and remote applications. It is sold exclusively in pallet quantities of 8, 10, or 12 panels.

The panel combines N-Type TOPCon cell technology with an anodized aluminum frame, AR-coated tempered glass, pre-drilled mounting holes, and pre-attached cables with solar connectors. All pallet variants share the same panel construction, electrical ratings, dimensions, and installation features.

Key Features

  • N-Type TOPCon Cells: Uses 18-busbar N-Type TOPCon cells with up to 25.3% cell efficiency.
  • 96-Cell Configuration: Delivers a rated maximum output of 335 watts per panel.
  • Low-Light Performance: Designed to maintain energy production during cloudy conditions and in morning or evening light.
  • PID Resistance: Cell processing and module material controls provide resistance to potential-induced degradation.
  • Quality Inspection: Every panel receives 100% electroluminescence double inspection to identify defects and help prevent microcracks.
  • Environmental Testing: Tested for UV exposure, thermal cycling, humidity freeze, and other environmental conditions.
  • Mechanical Load Resistance: Rated for a positive load of 5,400 Pa and a negative load of 2,400 Pa.
  • Weather-Resistant Construction: Built to withstand exposure to salt, ammonia, sand, high temperatures, and high humidity.
  • Corrosion-Resistant Frame: Uses an anodized aluminum-alloy frame for strength, corrosion resistance, and easier handling.
  • Flexible Mounting: Fourteen pre-drilled mounting holes support ground mounts, Z-brackets, pole mounts, and tilt systems.
  • Ready-to-Connect Wiring: Includes pre-attached 12-gauge photovoltaic cables and plug-and-play solar connectors.
  • Series or Parallel Configuration: Solar connectors support both series and parallel panel connections.
