Garth did a solar power installation for me earlier this year. The work was done competently and with enthusiasm and I can easily recommend him and his team. 

A few things stand out:

Firstly the electrical installation turned to be more complex than he quoted for. It was a three storey building with a difficult routing of wiring. He did not complain. Secondly, he did a complete re-mounting of the solar panels because the estate aesthetics committee decided that the panels where to visible. Again this was done without complaint or request for extra payment. Thirdly, and most importantly , there were several technical problemss with the Chinese Inverters I selected which he followed up time and again despite receiving very little or no support from the local suppliers. Lastly, I felt I could leave my home unlocked and unsupervised throughout the installation.
