  • Ballasted and pier driven ground mounts
  • Seasonal adjustment systems
  • Ballasted roof top
  • Penetrating roof top
  • Residential flush mounts
  • Awning & Facade systems
  • Customized solutions for project above 50 kW

2. What wind loads are Schletter mounting systems certified or rated?

There is no specific wind rating for solar mounting systems. Any mounting system can be designed to withstand wind loads of 240 mph and beyond. It is not a question of the mounting systems but a question of the costs and whether a building is capable of taking the loads aligned with a design for those wind loads. The modules usually do not withstand heavy wind loads.

3. What tilt range can mounting systems be adjusted to?

Schletter racks can be designed to any tilt from 0° to 90°.

4. Does Schletter offer tracking systems?

Yes, due to customer request, Schletter has begun offering a tracking system.

5. Can the Schletter mounting systems be used with any solar module on the market?

Yes. Schletter racks are capable of carrying any module.

6. Have Schletter mounting systems gone through wind tunnel testing?

Yes. Schletter has performed very thorough third party wind tunnel testing.

7. To what depth does the post on the ground mounted system usually need to be driven to?

About 4 to 8 feet

8. Is it possible to judge the embedment depth of the post on the FS or FS Uno systems just from a geotechnical report?

  • No. To get accurate results and an accurate embedment depth practical tests have to be performed on each single project site. The costs for these tests are included in the pricing of larger FS or FS Uno systems.
  • Basing the embedment depth only on geotechnical reports is very conservative. Especially on larger systems this often means that too much material is sold as the embedment depth was judged to deep.

9. Can the FS System be used in a residential application?

Yes. Check out our easy-to-install and affordable FS Mounting Kits available for purchase online at www.secure.schletter.us.

10. Does Schletter have a solution for landfills?

Yes. The PVMax and PVMini are ballasted ground mount systems and is an excellent choice for landfills. With concrete foundations, the main applications for this system are landfills and terrain that is lacking top soil and/or soil where the sealing membrane is not able to be penetrated.

11. What is the expected lifetime of Schletter racking systems?

Aluminum has a life-span of about 600 years. The galvanized and stainless steel parts we use in the systems are designed to last at least 50 years.

12. Is the post of the ground mounted FS System galvanized?

  • Yes the post is galvanized to ensure the lifetime of the PV system.
  • We use hot dip galvanizing. The post is galvanized after all holes have been drilled and everything is cut. This results in an advantage of a closed galvanized coating.
    • Many use pre-bend galvanized steel for their steel parts in a solar system. This has the advantage of being a little less expensive but the disadvantage is having cut edges and drilled holes exposed to the weather which in the end means corrosion will start much faster.

13. Can Schletter racking systems be used in a marine atmosphere?

Yes. The Schletter components are salt-water-fog-spray tested and have passed this test.

14. Is the Rapid Grounding Middle Clamp certified?

Yes. The Rapid Clamp is ETL Listed. The ETL Listed Mark is assurance that the product is compliant with safety standards, having been tested and certified by a third-party organization.

15. What is the torque for a bolt?

Bolt Size Maximum Torque (Nm) Maximum Torque (ft-lbs)
M6 & 1/4" 6 4.5
M8 & 5/16" 14 10.5
M10 & 3/8" 30 23
M12 & 1/2" 50 37
M16 & 5/8" 121 89
M20 & 3/4" 244 180

1. What is included in Schletter pricing?

  • All the material for the mounting systems as well as the clamping components for the modules.
  • Wet stamps on the structural calculations and drawings from a third party structural PE licensed in the state of the project.
  • Pre-assembly of major racking components.
  • For larger ground mounted systems: A geotechnical report and pull out tests are included in pricing.

2. What is the warranty on Schletter racking?

We offer a range of limited warranties from 5 to 20 years. Please contact sales@schletter.us for more information.

3. What is the general lead time for Schletter products to arrive on site?

Lead times are based on project size and requirements. Please contact Schletter to find out more information for your specific project. For components order online at www.secure.schletter.us.

4. Does Schletter test the soil of a project for corrosiveness?

Yes.

5. Do I need a special machine to get the posts into the ground?

  • Not necessarily a special machine, as many pile drivers can do the work. However a tool is needed that has the shape of our posts. Our posts have a special shape allowing for secure positioning in the soil and a reduced embedment depth. Whether the GAYK hydraulic ram is used, which Schletter supplies, or another tool, ease of maneuverability throughout the jobsite should be considered. Alternatively, the PVMax System uses concrete footings which sit atop the ground, and do not require pile driving.
  • Schletter has a program for renting and purchasing GAYK rams, email mail.us@schletter-group.com for a quote.

6. Does Schletter lease the pile driving machine out to customers and offer training for it?

Yes. The GAYK hydraulic ram may be purchased or rented (leased) by customers on a monthly basis, and there is training available for it.

7. Are Schletter engineers capable of recalculating a building to verify whether it is suitable for a PV installation?

Yes. Schletter engineers are capable of recalculating buildings to verify whether it can hold up to the loads of a PV system. However this is an additional charge for the customer. We use an independent third party engineer to ensure the accuracy of the calculations by an independent source.

8. Why does Schletter mainly use aluminum components instead of steel? Isn't aluminum more expensive?

    Schletter offers several steel systems for ground mount applications including the FS Uno, Duo, and FS Track II.
  • In recent years, steel has proven less expensive to buy on the commodity market compared to aluminum. However, aluminum is lighter in weight and when aluminum prices drop, it can be a more cost-effective choice. Speak with a Schletter sales representative to see which option is best for your project.
  • It is easier to handle aluminum on the construction site which saves labor costs. Especially on large scale systems the handling of the material is a cost driver. Transportation costs are lowered using aluminum.

9. What is the general mounting time of the ground mounted FS System?

This depends very much on actual site conditions. In general it can be said that an experienced crew of 8 people can mount 1 MW of the FS System in 10 days. (Driving the posts, setting up the rack and clamping the modules to the rack – no electrical work.)

10. Does Schletter train installation crews on the set up of the racking?

Yes. There are several ways that we offer to train the installation crews. That can be done at our facility in Tucson, AZ or we also can come out to the site to set up a couple of racks together with the customer. On larger systems this service is complementary, on small systems we need to charge for this service.

11. What is the general lead time to schedule the pull out tests on site?

We try to be as fast as required in being on site and performing these tests. Maximum lead time will not exceed 2 weeks.

12. What information do I need to submit to Schletter to receive a quote?

  • Visit our Request A Quote page and complete a project checklist for ground or roof.

13. How do I gain access to the client login and store? What features does it offer?

The client login is provided for current customers only. To apply, sign up at our Store & Client Portal. Approval may take up to two business days. The client login contains our residential software calculator, CAD drawings for components, sample drawings, and the Store section allows customer to buy small components online.

14. Can I buy a single component?
