UPS is good for smaller packages while solar panels and rails have to go freight and that is the bulk of the shipping cost.
See below the freight shipping cost for the average pallet going freight if your shipment is coming from our warehouse in CA. Note we have other warehouses in the United States, but our main warehouse is in CA.
Just as a heads up, the lines are not exact but approximate, and shipping costs can vary depending on what is purchased and how much, however if you are purchasing a full solar system for a home, this gives a good estimate.
You can see the costs for your specific system yourself when checking out using the cart.
This map is a means to get an approximation of how much freight shipping might cost for you when purchasing a solar system:
If you're a solar installer with multiple solar projects per year, the Mega Watt Club membership might be a good investment. For $950, you'll get free shipping on all orders for a year. If you're in California and have 4-5 solar systems you put on homes up a year, it would already makes financial sense, while on the East Coast anything more than 1 solar installation will save you money.
