Start with MD Fasolar

When to use MD Fasolar?
When you are looking for an aesthetic solution for a functional vertical application. Can be used as a secondary facade in a renovation project or as a second shell in a ventilated facade in new construction.

When no MD Fasolar?
If you are looking for the cheapest solution to harvest energy from the facade and the amount of energy plays a minor role, then MD Fasolar is certainly not the best solution. In addition to energy, MD Fasolar also provides architectural added value. That is why MD Fasolar is not the cheapest solution, but it is the best when it comes to energy-supplying facades.

Architectural details

What are the dimensions of MD Fasolar?
The solar panels with two rows of solar cells have a width of 35 cm and a variable length, depending on the number of cells to be used.

For solar panels that are 35 cm wide, the system repeat height can vary between 48 and 72 cm. For panels that are 20 cm wide with a single row of cells, the repeat height is between 24 cm and 55 cm.

Which material is suitable for decorative/reflective panel?
Most facade panel materials are suitable. Think of sheet materials from Trespa, Rockpanel, Alucobond, Eternit, or glass and aluminum. Do you have another material in mind? To be sure of the applicability, please contact us.

How often should the system be cleaned?
This depends on the environment. The panels only need to be cleaned once every three years. In general, the panels are sufficiently cleaned by the rain. This applies to the sloping panels on a roof, as well as to our solar panels.

What is the best way to clean solar panels?
The solar panels have a surface that consists of tempered glass. It is best to clean the solar panels with osmosis water. Osmosis water is water in which no minerals and salts are present. This prevents white spots on the panels that can reduce the yield. Moreover, this osmosis water has a stronger cleaning capacity than normal tap water, because it forms a connection with the dirt present. As a result, it will even remove dirt from the pores of the solar panels.

What about maintenance and repairs?
The solar panel to be repaired can be disassembled to exchange for another panel or to access the underlying panels for maintenance or repair work.

How is MD Fasolar connected to the building installation and the grid?
Depending on the type of converter that is used, one or more cables are led inside through the wall or the roof. Recognized installers provide separate electricity group(s) in the meter box, so that the system becomes part of the existing electricity circuit.

Solar energy details

Which type of solar panel is used in the facade system?
Creteq supplies high-quality crystalline solar panels. These solar panels have a 25-year guarantee for electricity. This means that after 25 years the yield is still at least 80% of the yield of the newly installed panels.

What are the specifications of the solar panels used?
The solar panels with two rows of solar cells have a width of 35 cm and a variable length, depending on the number of cells to be used.

For solar panels that are 35 cm wide, the system repeat height can vary between 48 and 72 cm. For panels that are 20 cm wide with a single row of cells, the repeat height is between 24 cm and 55 cm.

What about the sustainability of the solar panels?
All energy used to produce the solar panels is harvested from the facade within three years. This means that the ecological payback time of the solar panels is less than three years. The main component of the solar panels is silicon. This is one of the most abundant elements on Earth.

What is the annual yield?
The yield of MD Fasolar in the Netherlands is between 90 and 170 kWH/m2 panel/year. This depends on the reflection value of the decorative panels and the chosen orientation of the solar panels. Per square meter of vertical facade surface, this means a yield of between 35 and 75 kWh/m2 facade/year.

Examples:
• an installation on a flat roof provides approximately 108 kWh/m2/year of the solar panel and approximately 43 kWh/m2/year of the roof surface.
• a yield of 50 kWh/m2 facade/year with 100 m2 equates to 5000 kWh/year. This is what a family of four consumes per year. With this yield, 300 m2 of floor space can be illuminated for 2000 hours per year (8 W/m2).

Energy performance of buildings
The European Community has stipulated in the Energy Performance of Buildings Directive, no. 2010/31/EU, that from 2020 construction must be virtually energy-neutral. To achieve this, the national regulations on energy efficiency of buildings are being adjusted step by step.
