Van Der Valk Solar Systems: Length change thread-forming bolt

Van Der Valk Solar Systems announces that it will shortly change the length of the thread-forming bolts, used for the fixation of the side and back plates of the ValkPro+ system. The length will again go back from 10 to 20mm. Until recently, a bolt length of 10mm was required because the thread-forming bolt could potentially get in the way of the panel clamp bolt in the back foot. This risk no longer exists because the bolt length for the rear foot clamp has changed.

ValkPitched Trapezoidal profiles simplified

Van der Valk Solar Systems has simplified the ValkPitched Trapezoidal profiles. Due to their new design the profile can cover the same CTC distances between the crowns, which means that the range for each remaining profile will be expanded.Therefore they can remove three “intermediate profile lengths” from the product range.

Adjusted hole pattern

By adding two extra holes, the range per profile has been expanded. Download the datasheet via the link below for additional information.

With this adjustment, the following profiles will be removed from the assortment:

  • 7269240 Alu. Trapezium profile L=240 + EPDM
  • 7269320 Alu. Trapezium profile L=320 + EPDM
  • 7269400 Alu. Trapezium profile L=400 + EPDM


The profiles with the adjusted range combine perfectly with the other parts of the ValkPitched trapezoidal system, in every desired configuration.

Availability and deliveries

The profiles will be phased out when current stock has emptied. After this they will gradually deliver the profiles with the new range. At the same time the phased-out articles will be removed from the online calculation tool, the ValkPVplanner.

New price lists mounting systems in 2022

Our suppliers are still confronted with the consequences of the extremely increased raw material prices and scarcity on the market. Our suppliers have had to purchase the raw materials at higher rates to ensure sufficient stock. Therefore, they are forced to increase the sales prices for the products. This means concretely:


As of January 1, 2022

Esdec will increase prices by an average of 14% from January 1, 2022.


As of February 1, 2022

Prices are also rising at Van der Valk Solar Systems. Prices will increase with an average price increase of 7% from 1 February 2022. The price increase will not be the same across the entire product range, because it is highly dependent on, for example, the share of aluminum or steel in the product.

FlatFix Fusion has been updated

The FlatFix Fusion system has been successfully applied in many projects throughout Europe in recent years. Esdec’s research & development department is continuously looking for opportunities not only to develop new products, but also to make existing products even better. And that was done last year for, among others, FlatFix Fusion.

High and low base optimization
The high and low base, where the panels are attached to the mounting system, have been renewed so that they have even better and more durable clamping power. This is not only important for more extreme weather conditions, also when maintenance has to be carried out on the PV system, the securing must remain optimal after removing and replacing a panel.

Renewed end clamps
The clamp now has small bulges on the underside that fit precisely into holes in the high and low base. In this way, the clamp always remains in the correct position when tightening and installing can hardly go wrong. Esdec also looked at how it could be made easier to ground a row of panels. The solution for this has been found in adding a notch in the end clamp where grounding clips fit exactly. This ensures a nice and safe way of grounding.

Improved wind deflextors
The side plates have been modified and now have rounded corners. The most important update in this section is that the side deflectors now have push-out cable outlets. In combination with the cable exit guide, you can now bundle and dispose of your cables in an even safer way. This is also a desirable addition to the system’s advantages for strain relief of the cables.

Aluminum Panel Support ValkPro+

As solar panels are getting bigger, Van der Valk Solar Systems is continuously adapting their range to this. That is why they have added a new product for “extra” support for solar panels on flat roofs: the aluminum panel support for the ValkPro+ system.

Extra Panel Support ValkPro+ L10

For applications in areas with a high snow load or when very large panels are used, there is the option of equipping the mounting system with special parts to provide additional support for the PV panel. This extra support consists of a special front and rear foot, which can be clamped to the panel frame in the middle of the long side.

The aluminum panel support consists of a plastic and aluminum part. The plastic part consists of recycled rubber. An aluminum foot bracket is placed on top of the plastic part, which ensures a strong and solid connection to the solar panel.


The aluminum panel support is suitable for use on existing and new flat roofs. The aluminum panel support combines perfectly with the ValkPro+ landscape (L10) South and East-West system.

Projects with the Aluminum Panel Support ValkPro+ can be calculated from now on with the ValkPVplanner.

Price increases continue

As it looks now, the price increases will continue. Raw materials prices have risen due to shortages in raw materials, but transport is currently also playing a major role in the price rises. Container prices continue to rise and it is a struggle to get a container in China to Europe.

The latest update on price increases from our suppliers:

  • Esdec has increased prices by at least 5% from 7 July. They have already indicated that the next price increase will be on August 7th of more than 5% and this will be on top of the price increase of July 7th.
  • Enphase has implemented a price increase for only the microinverters from 1 July. This is a result of, among other things, the scarcity of silicon chips needed for the inverters.
  • SolarEdge announced as well that they will have a price increase from 1 August.
  • The prices of Helukabel are highly dependent on the copper price. Helukabel currently works with a new price list for each month.

FlatFix Wave Plus

As of July 8, Esdec will change the name of FlatFix Wave to FlatFix Wave Plus. The reason for the name change is that Esdec wants to develop different configurations of the FlatFix Wave system in the near future, based on the core elements of Wave (assembled module, tool-less clamping, high-compliance features).

The current configuration of the system and its components remain the same. However, with changing the name they did add a few new components that enable the mounting of even wider panels with FlatFix Wave Plus. After all, solar panels are not only getting longer, but also wider.

  • With a longer unit you can now mount panels up to 1149 mm wide. In concrete terms, this means that in addition to the current length of the unit, a new unit (about 6 cm added on each side of the unit) is available per 8 July.
  • The length of the panels (up to 2500 mm) is not an issue as two base units support each panel for maximized support. Stabilizers that ensure the rigidity of the system are now also available in two additional lengths. The wind deflector kit has also been adapted for this longer dual unit.


It is not yet possible to do a full project calculation with wider panels in the Esdec calculator. When you now select a wide panel (1070 mm and up) in the calculator, you will be referred to our project engineering department for support.

Introduction ValkPro+ ballast trays

Van der Valk Solar Systems are introducing a new option to increase ballast of PV installations: ballast trays for the ValkPro+ system.

These ballast trays are weighted by means of gravel or clinkers. The trays are placed on the ValkPro+ roof carriers. Its clever design makes it easy and quick to install. It is also a cost-effective ballast solution, because there is often already gravel on flat roofs. The gravel can simply be moved into the ballast trays. This also offers logistical advantages, because tiles no longer need to be ordered and transported.

The ValkPro+ ballast trays are made of corrosion-resistant steel and designed and calculated according to the latest standards. The ballast tray is applicable for commercial and residential flat roofs. Available for L10°, P10° and L15° in South and East-West configurations. Calculations for projects with ValkPro+ are made quickly and easily in the ValkPVplanner (the ballast trays can be added as a service item).

Update ClickFit EVO (steel roof)

Esdec announces two small updates for ClickFit EVO for Steel Roofs: installation of the mounting profiles now also possible with rivets and a new and improved screw.


It is now possible to attach the low and high mounting profiles of Esdec’s ClickFit EVO Steel Roof with rivets. A slightly larger hole has been made in the low and high mounting profiles so now both screws and rivets can be used. The profiles have already been updated and are already being delivered. This adjustment comes at the request of installers who prefer working with rivets. The fastening with the rivet has been extensively tested and guarantees the most reliable and watertight installation.

New and improved screw

For those who want to continue working with screws, an improved version is now available. Esdec has included a new self-tapping sheet metal screw in their portfolio which replaces the old one. This self-tapping sheet metal screw (6 x 25mm) is of high quality and has the best coating. Thanks to the highest corrosion resistance, they are ideal for use in coastal areas and on agricultural roofs. In addition, the material and coating also exclude galvanic corrosion on your roof. The screws can now also be tightened in two ways: Torx 30 and SW10. This means you only need one tool for all products.

The self-tapping sheet metal screw is used to mount the ClickFit EVO steel roof rails on trapezoid or corrugated steel roofs, to mount the ClickFit Basic mounting bracket to the trapezoid steel roofs (the same screw is used in FlatFix Fusion, to fix the wind deflectors and / or ballast trays). These multihead screws have been extensively tested and provide an even stronger adhesion. This makes that fewer screws are needed in the end. The sharper tip of the new screw makes it easier to screw through the steel. The screw with ring, in combination with the EPDM rubber on the profiles, provides a watertight seal. These new screws replace the old ones and are automatically displayed in the Esdec calculator.

”Extra long” lengths Side++ profiles

Van der Valk Solar Systems announces that as of today, they are fully switching to ”extra long” lengths for the Side++ profiles for pitched roofs.

Side++ profiles

The dimensions of solar panels are becoming larger and larger. For this reason, Van der Valk Solar Systems expanded the range of Side++ profiles for pitched roofs a few months ago with new lengths so that even the largest sizes of panels fit onto them. These new ”extra long” profile lengths are suitable up to a panel width of 1052mm with fewer couplings. The decision has been made to phase out the normal profile lengths and to switch completely to the ”extra long” Side++ profiles. The ”extra long” profiles are available in aluminium colour and black coated.


  • Greater ease of installation for panel widths up to 1052 mm with fewer couplings.
  • Better availability and shorter delivery times.
  • Smaller range and therefore more convenient ordering and less storage space.


From now on, the ”extra long” Side++ profiles are available. The ”old” lengths are still available as long as stock lasts. The new profile lengths have already been added to the online calculation tools ValkPVplanner and ValkKITSplanner.

Price increase for raw materials

Raw material prices continue to rise. This is also reflected in price increases at our suppliers (as of June 1st). Due to improving economies such as construction, the automotive industry and the renewable energy sector, the worldwide demand for raw materials is very high and delivery times are increasing. In addition, there is a limited supply on the world market because large countries such as China need a lot of raw materials for the internal market and the availability of containers is limited.

What exactly does this mean? The price for aluminum is now one and a half times higher than last year around this time. Steel has even doubled and the same trend is visible for plastics, copper and electronic chips. And in addition to the higher price, availability is a determining factor. As a result, our suppliers cannot avoid a price increase. What the future will bring us is difficult to predict in terms of the raw material market. In the coming months, the challenge for our suppliers to obtain materials at a reasonable price will be the most difficult task.

New lengths of Side ++ profiles for large solar panels (ValkPitched)

The dimensions of the latest generation of PV panels pose challenges for the mounting system. Until now, the Side ++ lengths were tailored to a maximum panel width of 1016mm. However, more and more panels that are wider are coming onto the market. In order to be able to mount these panels quickly and efficiently, Van der Valk Solar Systems has added four new lengths to the existing range, in addition to the existing profiles.

The four new “extra-long” profiles are suitable for a maximum panel width of up to 1052mm.

Update from SolarEdge: Optimizers

SolarEdge announced that the P370 optimizer is being phased out. At the moment, SolarEdge sees that many residential projects use panels that are round 350Wp. This trend will only increase in the (near) future. Because the panels with a capacity of around 350Wp require a higher current than the 11A which the P370 can handle, it has been decided to stop the production of the P370 optimizer. The alternative to the P370 is the P401. This optimizer can handle up to 11.75A, this doesn’t seem like much, but is a big improvement and enough to keep up with demand.
We currently have stock and will receive our last stock after October 12. Please contact our Sales department to discuss your needs.

In order to meet market PV requirements, ensure future compatibility and allow more flexible design rules for high power modules SolarEdge recently released a new firmware that improves P950 optimizer spec as follows:

  • Increased string current up to 18A (instead of 17A)
  • Increased string oversizing up to 18.500W (instead of 15.750W)

Existing inventory can be deployed, and it will be automatically updated to the new firmware (connection to the monitoring is mandatory).

New: extra-long back plates and mass carriers (ValkPro +)

The range for the ValkPro + system for flat roofs has been expanded with extra-long back plates and ground carriers, in order to be able to mount the largest panel sizes.

The dimensions of the latest generation of PV panels pose challenges for the mounting system. Until now, the ValkPro + system was suitable for mounting panels with a maximum length of 2120 mm in landscape position. By adding an extra-long back plate and ground support, it is now possible to use panels with a maximum length of 2320 mm.

Change of mounting holes in back plates

To increase the adjustability of the back plates, the design of the mounting holes have been changed: from now on there will be three 60 mm slots on both sides of the plate. Thanks to this greater range, the back plates can now always fit neatly to the sides of the system regardless of the panel width.

New: new product series for the mechanical anchoring of PV systems: ValkSolarFix

For buildings higher than 25 meters, in areas with very high wind loads or on roof structures that can only withstand very low loads, the use of “consoles” offers a solution for mounting the PV system.

The ValkSolarFix is ​​made of high-quality aluminum and can be attached quickly and easily to roofs with a timber or steel plate construction by means of special roof screws or a toggle anchor. A concrete anchor can be used for concrete roof constructions. The length of the screws or anchors can be adjusted to the thickness of the insulation material.


The special height of the ValkSolarFix is ​​perfectly matched to combine without further height adjustments with the ValkPitched system for pitched roofs and ValkPro + system for flat roofs. The large diameter of the collar of the ValkSolarFix provides a solid base on which the roof racks of the ValkPro + system can be attached directly.

The ValkSolarFix can be waterproofed into any type of roof membrane by experienced roofers. For this reason, the ValkSolarFix is ​​supplied without an additional membrane, so that the roofer can provide this himself and adjust it in his own way. This also offers great advantages with regard to logistics and keeping these types of products in stock with our distributors.

New: Black plastic cover caps for panel clamps

Van der Valk Solar Systems has developed a new product and added it to the range for flat and sloping roofs: “Black plastic cover caps for panel clamps”.

For PV systems using all-black panels, from an aesthetic point of view it is sometimes desirable to provide the visible part of the aluminium panel clamps in black colour. This was already possible for most of our systems with black anodized panel clamps, but now this can also be achieved by installing the black plastic covers that can be simply clicked over the blank clamps.

The covers can be applied to both new and existing installations. Think of ValkPro +, ValkDouble, ValkTriple, ValkQuattro and ValkPitched – Clamp mounting systems. The new caps are already available.

Update new packaging method of alignment pins for solar panels

Article 733020 consists of three separate parts: a plastic alignment pin, an M6x25 bolt and M6 collar knurled nut. Up till now, these have been combined per item in a separate plastic bag in a box of 150 pieces. This method of packaging meant a relatively large amount of waste material per article. That’s why Esdec decided that from now on article 733020 will be packed per bag (alignment pin, bolt, nut) in a bag of 100 pieces, after which these parts will be combined in the final packaging. This is a sealed plastic bag, with a total of 100 pieces of item 733020.


Article information

The change only concerns a change in the standard packaging quantity to 100 pieces, previously this was 150 pieces. There are no changes regarding item number, item description or price.

From now on, the change has been made for the items that are supplied from the stock of Van der Valk Solar Systems.

Warranty extension changes for commercial inverters

Last year SolarEdge changed their warranty extensions. A new change for the warranty extensions will start next year. Below an overview of the changes that have already taken place and the new changes that will take effect on 1 January 2021.

Changes since 1 October 2019:

  • The 15-year warranty extension for the SE15k, SE16k and SE17k can no longer be taken out. Alternatively, the 20 years can still be ordered (online).
  • The price of the 15-year warranty extension for the SE25k, SE27.6k and SE33.3k without DCD has been changed to € 317.
  • The price of the 15 year warranty extension for the SE25k, SE27.6k and SE33.3k with DCD has been changed to € 345.


Changes effective 1 January 2021:

The 15-year warranty can no longer be taken out, regardless of which type. There are a number of reasons for this:

  • The price difference compared to the 20-year warranty extension is so small that it’s not useful to support a separate 15-year warranty.
  • The 15 year extension cannot be concluded online because the customized product is only for the Dutch market. The 20 years, on the other hand, can easily be concluded online and the certificates are sent directly by email.

For the convenience of the installer, distributor and SolarEdge, as of 1 January 2021, only options will be available as found on the SolarEdge website:

New product in assortment: EPDM rubber shim

Van der Valk Solar Systems adds a new product in their assortment: EPDM rubber shim for mounting on steel roof tile plates. Mounting profiles on a pitched with steel roof tile plates covering can be challenging. Due to the overlapping tile plates, the pitch of the plates is slightly off compared to the roof pitch itself. This means a direct mounting of the profiles to the plates will create an issue with the levelling of the profiles.

The new “EPDM rubber shim” (739005) now offers a perfect and simple solution. By placing the rubber shims between the horizontal placed profile and the roof tile plates in the position of the fasteners, the angle of the profile is adjusted to match the roof pitch angle.


The EPDM rubber shims with pre-drilled holes of 6 mm diameter are placed behind the aluminium profile in the position of the mounting holes. The standard option to fasten the profile to the steel tile plates is by using aluminium rivets (779223).

Upcoming change in the production precess for aluminium parts

Van der Valk Solar Systems has changed their production process for the aluminium parts used in the adjustable panel clamps in black colour (products: 721550ZW en 721552ZW). The clamps will be anodized in black colour instead of coated.

The reasons for this change are:

  • The colour and appearance of the clamps matches better with the frame of the panels, which are also anodized.
  • The surface of the clamps is better resistant to scratches and dents and is more dirt-repellent.
  • Anodized aluminium has a better colour fastness when exposed to UV-light.
  • Anodized aluminium can be recycled without pre-treatments.

The anodized clamps can be recognized by the more matte appearance, compared to the coated clamps.


Price and availability

This change does not affect the material numbers or the price of the clamps. The transition to the anodized clamps will take place when the existing stock of coated panel clamps is finished (It is expected this will be around the end of January 2020).

The new universal side plate replaces the current side plates of the ValkPro+ L10 system, which now has a “left” and a “right” version, which are mirrored with respect to each other. These plates can be recognized by an “L” or an “R” on the narrow side.

Thanks to the new design, one universal side plate can now be applied on both sides of the system. This offers the following benefits:

  • A reduction in the number of stock keeping units.
  • The new design has no turned sides and therefore takes up less space.

The article number of the new side plate is 742540. The side plates for ValkPro+ L15 and P10 remain unchanged.

New generation inverters: TL-XE Series

In 2020, Growatt will launch the successor of the current MTL-S series. The new inverter generation is available in Q2: TL-XE Series. The Growatt MIN 2500-6000TL-XE is the new and most up-to-date smart inverter solution from Growatt. The compact design and high efficiency of up to 98.4% means that this inverter belongs to the new generation of small but powerful inverters.

The next generation has the following improvements:

  • The new inverters are 30% lighter than the MTL-S series.
  • New design with OLED display and Touch button
  • Smaller and more compact (the inverter is better protected against water and dust than its predecessor)
  • Easier to install
  • Standard Surge Protection Type II
  • Higher yield; 2 MPP trackers, per string 12.5A input current
  • AFCI is optional

Please note: the name of the models is not the same as its predecessor. The 5000MTL-S is being replaced by the 4600TL-XE and the 5500MTL-S is being replaced by the 5000TL-XE. The other models continue to use the same name until the 3000MTL-S (= 3000TL-XE).

Illegal range of Esdec products

E-mails are currently circulating in the solar PV market, sent by a company called Ekotechnik. These emails state that Ekotechnik offers Esdec products produced in India, namely the FlatFix Fusion product. This is an incorrect and misleading message.

The products that Ekotechnik offers are material copies that the company has produced illegally, without the permission of Esdec. The quality and weight of the components offered do not correspond to the Esdec standards. This means that the results of the Esdec calculator do not apply to Ekotechnik products.

Esdec wants to emphasize that it does not offer any R&D or design support to parties that have purchased the aforementioned material copies from Ekotechnik. These material copies are also not covered by the Esdec warranty on the original Esdec products. Esdec assumes no liability for complaints arising from the use of Ekotechnik’s material copies.

If you have any questions about this, do not hesitate to contact PVO or contact Esdec directly.

Change in packaging quantity and packaging method for the ValkPro + system back plates

There is a change in the packaging quantity and packaging method of the back plates for the ValkPro + system (code numbers 742510 through 742526). The number of back plates per standard quantity changes from 50 to 100 pieces. The back plates are now placed next to each other in two stacks of 50 pieces, instead of one stack of 50 pieces. The reason for the change is to add more stability to the package, so that it can be stacked and stored safely.

The new type of packaging per type will start when the existing stock of back plates is gone. The expectation is that for most articles this will be mid January 2020.

Change in composition of adjustable panel clamps (721550 and 721550ZW)

In mid-December 2019, these clamps will now be fitted with a standard stainless steel nut instead of a stainless steel locknut. Due to the decreasing frame thicknesses of the panels in the market, clamps have to be tightened further and further, which increases the risk of the occurrence of so-called “cold welding”.

The purpose of the modification is therefore to reduce the friction between the bolt and nut during the tightening of the clamps, so that the heat development remains lower. The nut is also further tightened during pre-assembly (at 40 mm frame thickness), so that fewer revolutions are required to clamp the panel. This will eliminate the risk of “cold welding” and will also further increase the installation speed of the clamps.

The panel clamps are equipped with a plastic nut holder, so there is no direct reason to use a lock nut. A lock nut has no influence on the clamping force of the panel clamps. Tests have shown that the nuts will not shake loose during transport of the clamps.

Profiles for trapezoidal roofs are now always covered with EPDM rubber on the bottom

From 1 December 2019 the aluminium profiles for trapezoidal roofs will always be covered with EPDM rubber on the bottom of the profile, for the purpose of sealing. This was already the standard for fixing the profiles by means of steel sheet screws and now also applies to the fixing method by means of pop rivets. Previously, this last method used separately delivered EPDM plates.

In case the profiles are attached by means of pop rivets, the pop nails can simply be pushed through the hole in the profile and through the sealed EPDM rubber.

Note: there is no need to make a hole in the rubber in advance. This method ensures that the rubber closes accurately around the pop rivet and ensures more ease of installation.

* The profiles without EPDM rubber are available until December 20, 2019 and will disappear from the range afterwards.
