SALE WATTSTUNDE: Solar technology on offer – modules, sets & accessories reduced

In the SALE WATTSTUNDE collection at Solarkontor, you'll find selected WATTSTUNDE brand products at attractive promotional prices. If you want to optimize your energy supply in your motorhome , van , boat , or garden shed , the sale is the perfect opportunity: secure proven solar technology at a lower price – while supplies last!

Offers change depending on availability. It's especially worth checking back if you're planning a new system or want to expand an existing setup – for example, with an additional module, suitable cabling, or practical components for mounting and connection.

What you typically find in the WATTSTUNDE sale

  • Solar modules (e.g. for mobile and stationary applications)
  • Complete solar kits for a quick start
  • Mounting and connection accessories (cables, plugs, adapters, roof penetrations, etc.)
  • System technology for integration into your vehicle's electrical system (depending on the offer)

For which applications is WATTSTUNDE particularly popular?

WATTSTUNDE is frequently used when robust, practical solar solutions are required – especially in mobile applications. Typical areas of use include:

  • Camping & Vanlife: Power for lights, chargers, laptop, water pump or cool box – more independent on the go.
  • Motorhome: Solar technology as a supplement to shore power – for greater self-sufficiency while traveling.
  • Boat: Supplying onboard consumers and assisting with recharging.
  • Garden shed/Off-grid: Electricity where there is no grid connection or where you deliberately want to remain independent.

This way you can quickly find the right sale offer.

1) Define system objective: “Retrofit” or “rebuild”?

If you already use solar power, make sure that new components are compatible with your existing system (e.g., voltage level and connection type). For beginners, solar kits are often the easiest way to start because the components are already matched.

2) Consider assembly & connection directly.

Especially during sales, it's worth considering not only the solar panel itself, but also the installation and wiring . Suitable accessories save time during installation and help to set up the system cleanly and safely.

3) Decide quickly when there are significant discounts.

Sale items are often only available in limited quantities. If you see a suitable WATTSTUNDE offer, it can pay to act quickly – especially for popular standard sizes and sets.

More choices: WATTSTUNDE range & other deals

Want to see more than just the discounted items? Then take a look at the WATTSTUNDE collection . You can also find other promotions under SALE | all current offers .

Tip: If you are planning an off-grid solution, also look into the topics surrounding self-sufficient power supply – there you will find complementary components to combine generation, storage and use in a meaningful way.
