Steady module planning after the 2026 supply swing

In spring 2026 the European module market went through a short, sharp swing. China ended the VAT export rebate for PV products on 1 April 2026. In the weeks before, many buyers pulled orders forward and built stock. After April, shipments to Europe slowed while that stock was used up and contracts were renegotiated.

By early summer, market reports described a calmer picture: European inventories had normalised, and buyers had moved from waiting for lower prices to buying for real projects.

For an installer, the useful lesson is not about guessing the next move. It is about planning so the next swing hurts less.

1. Buy for your pipeline, not for a headline

Rushing to stock up ties up cash and warehouse space, and it locks you into one module type for months. A better habit is to match orders to signed or very likely jobs, with a modest buffer for repairs and small add-ons.

2. Keep two approved module options per segment

Have two datasheets you are happy to design with for residential and two for commercial roofs, with similar dimensions and electrical values where possible. If one becomes hard to get, your designs, string plans and quotes need only small changes.

3. Put validity dates on every quote

When supply conditions move quickly, an open-ended quote becomes a risk. A clear validity period, and a short note that the module model may be replaced by an equivalent, keep both sides honest.

4. Check the paperwork before the pallet arrives

Whatever the market does, the basics stay the same: IEC 61215 and IEC 61730 certificates for the exact model, the current datasheet, and the warranty terms. A quiet market is a good time to file these for the modules you use most.

5. Talk to your supplier early

A short call about your next three months of jobs helps your supplier plan, and it helps you hear early about longer lead times or model changes.

At PVDIS we prefer steady planning over panic buying. If you want to talk through your next quarter's module needs, our team is happy to help.
