Solar Panels

[Carrie]

Solar panels system only reach 80% of their specified peak. The reduction in power from particulate build up typically lies in the 5%-15% range

All the data is compiled through laboratory test conditions, clean.

Then there is temperature co-efficiency effects.

Has anyone ever had there solar performance checked, below is a voucher available for all with a company that provides full uk coverage, who install equipment that monitor the solar performance and alert them of any issues as soon as they arise.
I had this fitted and all was good I was called by the company alerting me to an issue and they sent an engineer who found a fault and repaired it.
it made me realize that if I hadn't had it installed it could have been months before anyone could have discovered it which means months of lost performance.
I got an outstanding service from the company and would recommend this and the company to anyone.

Has anyone ever had there solar performance checked,

I read the meters every friday morning. Think I would spot quickly if output was off the pace. and it costs me 5 minutes of time

 

[woodyd1]

yes I do as well I wasn't convinced on the idea because i don't like changing things but after a few emails and a visit from the company I can honestly say I wish I had done it earlier its certainly worth looking into

Not much to go wrong. My clients get a service every 2 years. All I tell them to do meantime is turn all dc isolator off and switch 1 on at one time to see if all read the same generation. It's a quick and easy job. Most problems are dc connections albeit some Earth faults need testing unless your inverter alarms in this case.

Production on multiple inverters should be within 5% of each other depending on dc runs/links and orientation.

inverters usually have a fault output relay that closes when the inverter detects a fault, a gsm can alert you with this closing contact function, some people check their system regular but some do not look at them for months on end.
