Reviewing Solar panel detail, the item, Wp is referenced in their specification.  eg  150Wp.

 

Can anyone give an example of what this might mean please in terms of real output.  I appreciate that the output will depend vary much on the light conditions etc - but what might a 150Wp panel output in tems of Amp-hours during a normal summer day in England for example??   Or any similar meaning ful comparison?

 

Thank you

    On a summers day in full sun my 150w panel will give around 8 amps, less in cloudy / winter weather. The controller does float charging at 13.8v and also when the battery gets low a boost charge of 14.4v. Last February it did keep my 110amp battery fully charged for a 4 day break off EHU and 2 weeks in July.
