How to calculate the landed cost of imported solar panels

Step 1: Start with the product cost

Begin with the supplier price for the whole order. Note the incoterm: ex-works means the price is at the factory gate, FOB means it is loaded at the origin port. This matters because it tells you where your other costs begin. Record the total order value and the total watts, because you will divide by watts at the end.

Step 2: Add freight and insurance to get CIF

Add the international freight quote (ocean freight for panels in most cases) and cargo insurance. Product cost plus freight plus insurance gives you the CIF value, cost, insurance and freight, to the destination port. CIF is important because customs usually calculates duty on the CIF value, not the bare product price.

Step 3: Calculate import duty and taxes

Apply your country's import duty rate for solar panels to the CIF value. Add any additional import taxes or levies that apply. This is the line that varies most by country and by the origin of the goods, so use the rate for your specific corridor. The result is the duty and tax payable at the border.

Step 4: Add clearing, port and inland costs

Add customs clearing agent fees, port handling and terminal charges, documentation fees, and any demurrage risk. Then add inland transport from the port to your site. These lines are individually small but together they are real money, and leaving them out is the most common way buyers under-estimate landed cost.

Step 5: Total, then divide by watts

Sum every line: product + freight + insurance + duty and taxes + clearing and port + inland transport. That is your total landed cost. Divide it by the total watts in the shipment to get landed cost per watt. Now you can compare this order against any other quote on a true, delivered basis.

Worked example in shape (not exact figures): if a container of modules costs a certain amount ex-works, and freight, insurance, duty, clearing and inland transport add roughly a quarter to a third on top depending on the corridor and duty rate, your landed cost per watt is meaningfully higher than the ex-works quote implied. Run the real numbers for your corridor and the gap is often decisive between two suppliers.
