Installing flexible solar panels

There are a number of important consideration when installing flexible solar panels.

Owner and engineer Phil has undertaken extensive research and testing regarding the installation of thin, flexible solar panels and has acquired a wealth of information regarding the do's and don'ts of installation to ensure longesvity of the panels.  For example:

  • Installation methods that stresss the solar cells
  • Installing on canvas
  • Air gap or not air gap?
  • bonding methods
  • substrate expansion particularly on some fibreglass

This knowledge has been accumulated over many years so it is too lengthy to document here.  Also there is significant Intellectual Property (IP) which we would like to protect as our specialist knowledge is sometimes plaguarised and used on websites of online sellers to create credibility for the cheap products they sell.  If our information is used in this way it can create a false sense of security for customers thinking they are purchasing from a specialist seller with knowledge and experience when in fact they have not acquired that information ethically.  This then compromises the reputation of the industry as a whole if customers feel deceived.

We are happy to share our learnings with genuine customers so feel free to give us a call.

Blocking diodes v By-pass diodes

A diode is the electrical equivalent to a non-return, or one-way check valve for water, i.e. the diode only allows current to flow in one direction.  

In most cases the two diodes are physically the same however they are installed differently and serve a different purpose.

By-pass diodes: All solar panels have by-pass diodes(s).  They preven current passing through weak or shaded cells.  This prevents those cells from overheating and causing damage to the cell.  In other words it by-passes weaker or partially shaded solar cells by providing a current path around the cell(s).

Blocking diodes: These may be required if you connect more than one panel together in parallel. If one panel becomes shaded a blocking diode would prevent current passing backwards from the unshaded panel into the shaded panel.
