Our solar panels continue to perform well

Performance of solar photovoltaic panels at Ashton Hayes Sports pavilion

The generation performance of the solar photovoltaic panels at Ashton Hayes sports pavilion has been remarkably consistent since they were installed seven years ago (Figure 1). This has occurred despite fluctuations in sunshine hours over the years (see Figure 2 below). Quarters are seasonal.

Quarterly sunshine hours at Northwich have varied over the period with even this summer having a lower peak than 2013 and 2014 when summarised over a whole quarter (Figure 2).

However, there remains a strong correlation between sunshine hours and panel generation as shown in Figure 3 below. Note the difference between winter/spring figures (lower left points) and those from spring and summer (upper right).
