Well it’s been a little while since I typed one of these. There are a few reasons (including a broken leg!), but mostly it’s due to being occupied with other projects – most significantly finishing the new IET Solar PV code of practice, which I am pleased to say should be published later this month.
Martin Cotterell argues that the solar industry needs something in place to make sure that battery systems are sold appropriately; there is the potential for customers getting charged loads extra for a battery 'add-on' that doesn’t really give them a whole lot of benefit.
From 1 March, solar arrays installed with inverters that do not comply with G83/2 may lead to the DNO refusing to connect your project. Martin Cotterell explains what installers should be looking out for and how to prepare for the new requirements.
Where do you sit; are service and maintenance visits to a solar PV system a necessary and worthwhile exercise, or just a waste of money? This was the question posed to me today by a customer. My answer was: “Well that depends on the system, the installer and the way the system is behaving.”
Now I don’t know if you were affected by the power cuts over the holiday period, but some of the media coverage regarding the power outages made me consider the attitude we have to our electricity supply.
Potential Induced Degradation (PID) is a topic that’s been around the PV industry for a while, but until fairly recently I had not been paying it that much attention. This changed for me at Solar Energy UK 2013 in Birmingham when a manufacturer giving a talk said they had seen evidence of PID reducing output in a particular system by 60% - yes 60%!
