Are some solar panel Brands better than others? Sharp?

Says it all in the title.  Also if getting a quote what questions should I ask?

Yes absolutely. Check out any you are offered- most of the cheap ones are made in China, have a short life and produce less power

I have two systems on the same roof, the Trina system gets the sun a few min early over the sharp system,todays generation looks like this:

Trina solar/Growatt system (4.6kWp 3 years old) made 5.5kWp (=1.195kWp /kW for each kW of generation.

 Sharp/solar Edge + Optimizers 5.9kWp (8 weeks old) made 7.28 kWp (=1.223kWp /kW for each kW of generation.

The Sharp system was about £30 less to install.  Make sure the installer is MCS registered, usual advice is to install as many panels as you can/afford while tha scaffolding is up.

I've helped 175+ homeowners with their installations - almost all have Sharp followed by Solarwatt & REC panels. Not a single issue to date and the newest generation of bifacial panels are superb. 

There are few products that can compete on price with the low end, low ethics Chinese owned brands, while offering a 25/30 year guarantee (not the same as a warranty from those brands).
