Solar system maintenance.
I recently received a cold call from Optimal Energy Solutions offering to give my solar system a thorough check. This was quite nicely timed as my system is over 14 years old and never had any maintenance and considering the average life of an inverter is apparantly 12 to 15 years according to Google it seemed a good idea. Their representative arrived on time as planned and checked everything explaining as he went what he was doing. I agreed that the inverter should be replaced and the panels cleaned. This was done efficiently on the day planned. I have now signed up to a maintenance plan.
