Astonishingly one in three solar PV systems we examine have serious defects. The root cause of this startling statistic can be tracked back to the drastic changes made to feed-in tariffs by the Government over the last 4 or 5 years. This created “feast and famine” cycles which has meant that even the good installers have often rushed installations and then not re-checked or inspected them later to make sure they are installed correctly and that all the required documentation is in place. In addition to this there are of course the less scrupulous, albeit MCS accredited, installers who viewed the solar PV market as a opportunity to make short term profits and have sought to maximise those profits often at the customers’ expense by cutting corners to reduce design and installation time and by sourcing cheaper and inevitably less reliable key components (panels, inverters, roof mounting kits). Those same installers are now no longer around to pick up the pieces having successfully completed their solar PV “smash and grab raid” and moved on to the next “big thing” in a fresh company leaving all their liabilities behind. Storm damage is also a factor but is less of an issue in our experience.
The consequences of this firstly are a significant number of installed solar PV systems are not producing the financial and environmental benefits that the customers were expecting when they made their decision to invest in solar PV. Secondly, in many cases, the absence of key documentation including equipment warranties and testing certificates may expose customers unnecessarily to the financial consequences of key component failure and even invalidate insurance policies. Finally, in more extreme cases, the solar PV system may actually expose the unsuspecting customer to health & safety and even fire risks.
To make sure your solar PV system is the asset you wanted and not the liability you didn’t know you had we recommend the following:-
