Customer Reviews
Good value on solar panels
I was looking for a good deal on some Solarmodule and saw their Solarmodul Paketpreis. It seemed like the best option for my budget. The pricing was really attractive compared to other places I looked at, especially with the size of the order. Shipping wasn't free, but it was fair for the number of panels. They arrived well-packed and without any damage. For a first-time buyer like me, it felt like I got a solid amount of value for what I paid. Happy with the overall cost-effectiveness.
Got my inverter, all good
I bought a Wechselrichter from them a while back. It was pretty easy to find what I needed on their site. The price was alright, nothing crazy expensive. Delivery took about a week, showed up without any damage. I installed it and it's been working fine ever since. No complaints really, just a straightforward online shop experience.
Decent deal, some confusion
I bought a Balkonkraftwerk Komplettset Angebot. The price was competitive, especially with the discount that was available then. Delivery took 8 days which felt a bit long, but it arrived safely. Everything was in the package. My only minor gripe was the tracking info wasn't updated very often. Customer service was okay when I called about it, but they didn't have much more info than I did online. Overall, a solid purchase, but the communication on shipping could have been better.
Always reliable for components
This was my third time buying from Sunpower4u, and like before, the experience was consistent. I needed some MC4 Stecker and Solarkabel for an expansion project. The items were exactly as described and good quality. Previous orders for a Wechselrichter and Montagesysteme also went smoothly. I always checked their Komplettset Angebot first, but for specific parts, they usually had what I needed in stock. It's a shame they've closed down, as I found them quite dependable for specific PV components. Shipping times were generally reasonable for me, usually around a week to Berlin.
Good product, quick delivery
I ordered a DTU Stick. It arrived fast, took about 4 days to get here. The stick worked right out of the box. No issues with the purchase.

Share tips, ask questions & help fellow shoppers save more
Hey, thinking about a balcony power plant. Is Sunpower4u still selling those full kits or are they gone?
Does anyone know if they had good deals on those micro-inverters? Was hoping to grab one cheap.
