Well July was largely a wash out in terms of a British Summer. Many days were cloudy or fully overcast and we had a great deal of rain.  Good for the Celerity Gardens, but not so ideal for our solar panels!  In the last week we did manage to get some nice days though, which pushed our generated totals to almost 20% of what was predicted.  So, our worst month so far, but still a very good one in terms of reaching our annual target.

This month is a good example of how the output from solar PV can fluctuate wildly from day to day. This lack of consistency is what makes both solar and wind energy a challenge to integrate into our National Grid, but can be overcome through predictive models, improved infrastructure and suitable backup power in the form of nuclear or traditional power plants. Contrary to popular belief, this does not make renewables a waste of time. Just because traditional power plants will be needed for many years yet, when considered in a backup role, they do not need to burn fossil fuels unless needed.  To put it another way - on windy days less coal would need to be burned, which is obviously a good thing. And this situation can only improve the more we add to our National renewable capacity.

In the graph below, the yellow line indicates the average level we needed to reach each day (13.53kWh) in order to meet the predicted monthly total.  The blue line shows the average level we actually reached (16.2kWh).
