Who is authorized to install solar modules?

For connecting AC power installations, the law requires that the work must be carried out by an accredited, professional electrician. The roof installation and the DC side wiring should be carried out by a qualified tradesman with appropriate experience (solar installation specialist, solar power consultant, etc.).

What must be considered with regard to yield forecasts?

Yield assessments should be prepared using software programs that are supported by the industry standard, and they should clearly include all pertinent data so that the input values can be verified critically and for consistency. The Technical Support service of Solar Frontier Europe recommends using PVSyst as the software support, and consulting reliable sources of weather information for the local region. Supporting help may also be derived from comparison data with other, similar systems in the area or from customers who already own a Solar Frontier installation. The subsection entitled "Case Studies" lists a large selection of documented systems. You can also find real yield data in various locations, particularly the menu item "Output data PowerSets".

 

How will I be informed about faults?

Depending on the size and complexity of your system, it may be advisable to implement a monitoring system, the scope of which may range from a regular check of the inverter display to a user-friendly remote monitoring unit.

For more information about fault reporting, please refer to section "9.9 Troubleshooting" in the installation manual for our PowerSets.

How do the orientation and inclination angle of the roof affect the yield?

The degree to which these factors are significant depends on the latitude of the installation location. The orientation and inclination angle of a system is of critical importance to your yield.

In order to be able to forecast the yield from a specific system, it is recommended to use suitable simulation software such as PVsol or PVSyst.

Is a certain mounting system recommended?

The Solar Frontier PowerModules are compatible with all standard, commercially available mounting systems. We do not recommend one system in preference to the others. However, in the case of elevated module arrays in partial shadow, better results are achieved if the modules are arranged vertically (portrait arrangement).

What requirements should be considered in areas of heavy snowfall and high winds?

Steps must be taken to ensure that the maximum permissible snow and wind loads for the SF modules are not exceeded. According to IEC specification 61646, snow loads on the front and wind loads on the back are guaranteed up to 2,400 Pa on the S series module; although the load limit for the module is above 3,000 Pa. More detailed information on this subject can be found in the product datasheets in the Download area of our homepage. For locations where a higher snow load is expected, you are advised to contact the Technical Support service of Solar Frontier Europe GmbH for information about the deployment of W series modules. These are certified to sustain static loads up to 5,400 Pa.

Is it possible to install the modules in corrosive atmospheres (e.g., atmospheres with heavy ammonia load from chicken farming)?

Yes. The Solar Frontier PowerModules have passed the certification tests for ammonia resistance. [Certificate issued by TÜV Rheinland on 28 June 2013: 2PfG 1917/05.11 "Ammonia corrosion testing of photovoltaic (PV) Modules"]

This certificate can be viewed on our homepage under menu item Products  Certificates.

What requirements should be considered for atmospheres with salt water content?

The Solar Frontier PowerModules can be installed in atmospheres with a salt water content. They have passed the TÜV certification tests for resistance to salt mist [Certificate issued by TÜV Rheinland on 28 June 2013: IEC61701:2012 "Salt mist corrosion testing of photovoltaic (PV) modules"].

This certificate can be viewed on our homepage under menu item Products  Certificates.

What requirements must be considered with regard to humid environments?

The Solar Frontier PowerModules can be installed in environments with a relative humidity between 45% and 95%.

What requirements must be considered with regard to environments in which the module surface may become covered with sand?

In general, the self cleaning function of the modules is less effective at low inclination angles. At sites where there is a high likelihood that the modules will become dirty, it may therefore be necessary to clean the modules regularly by hand - particularly in installations with low inclination angles - to guarantee good yields in the long term. For more information about cleaning guidelines, please refer to our installation manual. The manual is available in the Download area. 

What is the specific weight of the Solar Frontier modules including the substructure?

Our PowerModule has a weight of 20 kg spread over an area of 1.23 m². This is equivalent to 16.26 kg/m². For substructures, the following weights should typically be added for roofing:

  • Trapezoidal sheet metal roofs: approx. 7 kg/m²
  • Tiled or pantile roof: approx. 10 kg/m²
  • Flat roof with elevated mounting (no ballasting): approx. 15 kg/m²

Are there any Solar Frontier reference systems already?

You will find many examples of completed Solar Frontier systems in the "References" area on our homepage. The subsection entitled "Case Studies" lists a large selection of documented systems. You can also find real yield data in various locations, particularly the menu item "Output data PowerSets".

How can I view the yields from my system?

Register on the "Safer‘Sun Public" internet portal and you can view the yields from your system for 2 years free of charge.

For full information about how to register on the portal, please refer to section 9.7 of the installation manual for our PowerSets.

I would like to install a PowerSet, but I have two different roof inclinations. Is it still possible?

Since the Solar Frontier inverters only have one MPP tracker, we recommend that all modules connected to an inverter should have the same orientation and inclination. In PowerSets that include two inverters or a combination of two PowerSets, it is possible to equip the east and west side, for example, with one PowerSet each.
