How will tariffs affect solar panels & inverters in 2025?

In summary, as of April 2025 we see solar panel prices up by 20–40% (depending on origin), inverters up ~10–30%, and battery costs up significantly (~30% or more) compared to pre-tariff levels. These increases correlate directly with the reciprocal tariff rates imposed (34% on China, 36–49% on SE Asia, etc.), underlining the tariffs’ impact.

What is the new tariff policy for inverters?

Under the new policy, all imports face at least 10% tariff, and specific countries face more – China-made inverters now see ~34% tariff, European inverters ~20%, South Korea 25%, etc.

How do tariff changes affect battery Energy Storage pricing?

The tariff changes have had a major impact on battery energy storage pricing, since a large share of solar-related battery systems (especially residential and commercial battery packs and battery cells for grid storage) are imported. Most lithium-ion batteries used in U.S. solar-plus-storage systems come from China or Southeast Asia.

What is a tiered rate plan?

A tiered rate plan is one in which the charges for energy increase as the monthly kWh increases surpasses a set of defined tiers in your utility tariff. You can enter this rate information using auto fill feature or manually in Enphase cloud electricity rate editor.

Are microinverters tariff-free?

Some microinverters and power electronics, which often were made in Asia, are similarly affected – however, companies like Enphase (U.S.) anticipated tariffs and diversified manufacturing to Mexico and India in recent years, meaning a portion of inverter supply is tariff-free.

Are all battery suppliers affected by a tariff?

It’s worth noting that not all battery suppliers are equally affected. South Korean giants like LG Energy Solution and Samsung SDI, which export battery cells and packs to the U.S., now face a 25% tariff (South Korea’s rate) – higher than before, but still lower than China’s.
