New federal trade measures will increase the cost of imported solar panels and key solar manufacturing components beginning December 4, 2026.
The new policy, issued under Section 232 of the Trade Expansion Act, establishes a 15 percent tariff on covered solar products made from polysilicon, including certain wafers, cells, and modules, regardless of country of origin. It also creates minimum import prices intended to support domestic manufacturing and reduce reliance on foreign supply chains.
While the long-term effect on solar pricing will vary by manufacturer and supply chain, the direction is clear: solar equipment costs are likely to rise in 2027.
Western Solar Planned Ahead
In anticipation of upcoming tariffs, Western Solar has already proactively secured the solar module supply and pricing needed to support our customers through the end of 2026.
That means customers moving forward with Western Solar this year can receive current pricing without an added Section 232 tariff increase. A system does not need to be installed before December 4th to benefit from the inventory and pricing we have already secured. As always, final pricing depends on the project design, equipment selection, site conditions, and the validity period stated in the proposal.
We made this commitment because uncertainty should not be passed unnecessarily to our customers. With more than two decades of experience in the solar industry, we have worked through changing incentives, tariffs, supply constraints, and equipment shortages before. Planning ahead allows us to maintain quality and provide more predictable pricing.
Does a 15 Percent Tariff Mean Solar Systems Will Cost 15 Percent More?
Not necessarily.
Solar panels are only one portion of the total cost of a professionally installed solar energy system. Design, permitting, electrical equipment, racking, labor, project management, and utility interconnection all contribute to the final price.
The tariff also affects manufacturers differently depending on where their polysilicon, wafers, cells, and finished modules originate. The new minimum import prices may ultimately have as much influence on equipment costs as the tariff itself.
For those reasons, a 15 percent equipment tariff does not automatically translate into a 15 percent increase in the total price of a solar project. However, customers should reasonably expect upward pressure on solar pricing once existing inventories and supply agreements are replaced.
What This Means for Washington Homeowners and Businesses
There is no need to make a rushed decision. Solar is a long-term investment, and equipment quality, system design, installation standards, warranties, and ongoing service remain more important than beating an arbitrary deadline.
However, homeowners and businesses already considering solar may benefit from completing their evaluation in 2026 while Western Solar’s secured supply and pricing remain available.
Western Solar has served Northwest Washington since 2002. We design, install, and service solar, battery storage, EV charging, and intelligent energy systems with our own experienced local team.
If you are considering a project, we can evaluate your property, energy use, goals, and available options and provide a clear proposal based on the supply and pricing we have secured.
