Estimated shipping time

You can typically expect your items to arrive within 4–7 business days, depending on your location and product availability.

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 400-watt monocrystalline solar panel is designed for residential, agricultural, commercial, and off-grid solar installations. Its 24V design and 108-cell configuration support both stationary and mobile solar applications, including RVs, cabins, and boats.

Multi-busbar cell technology, AR-coated tempered glass, PID resistance, and low-light performance support energy production across varied outdoor conditions. An anodized aluminum-alloy frame, pre-drilled mounting holes, and pre-attached solar connections provide multiple installation options.

Key Features

  • Monocrystalline Cells: Uses 10-busbar monocrystalline solar cells with up to 23.2% maximum cell efficiency.
  • 108-Cell Configuration: Delivers a rated maximum output of 400 watts.
  • Positive Power Tolerance: Rated at 0 to +5W to provide at least the rated power output under standard test conditions.
  • AR-Coated Tempered Glass: Uses 0.13-in. high-transmission, anti-reflective tempered glass for sunlight capture and durability.
  • Low-Light Performance: Designed to maintain energy production during cloudy conditions and during morning and evening hours.
  • PID Resistance: Advanced cell processing and module material control help resist potential-induced degradation.
  • EL Inspection: Panels are 100% electroluminescence inspected to help identify and minimize microcracks.
  • Environmental Testing: Tested for UV exposure, thermal cycling, humidity freeze, and other environmental conditions.
  • Mechanical Load Resistance: Rated for approximately 112.8 lb/ft² positive snow load and approximately 50.1 lb/ft² negative wind load.
  • Corrosion-Resistant Frame: Uses an anodized aluminum-alloy frame for strength and corrosion resistance.
  • Multiple Mounting Options: Eight pre-drilled mounting holes support Z-brackets, tilt mounts, pole mounts, and ground installations.
  • Pre-Attached Connections: Includes 12 AWG pre-attached cables and waterproof solar connectors.
  • Water-Resistant Components: Features an IP68-rated junction box and IP67-rated solar connectors.
  • Certified Construction: Certified to UL 61730, IEC 61215, and CSA C22.2 standards.
