Eastern of England faces a number of significant risks to its future water supply, which could have a catastrophic impact on the area’s communities, economy and environment if left unchecked*.

The boundary of the site is over 4 miles long. If East Suffolk Council abides by it's own planning policies the site will need to be screened, usually by a double row of native hedging. If the entire site is screened this means over 8 miles of hedging (4 miles x 2 rows).
Commercial nurseries give similar advice to each other regarding watering which is:
Let's assume plants don't need watering for half a year so they need watering for 26 weeks. Let's also assume they are watered only once per week and there are 3 plants per metre. The final assumption is that not all of the site boundary will need hedging so only 4 miles of the4 4.7 miles will be watered.
So for the first two years the total water consumption is:
East Anglia was in drought last year and more droughts are predicted. Do we really need to waste 40 million litres of water on screening something that very few residents want here?
Dust accumulation has a major impact on panel efficiency and consequently, a whole industry has grown up to clean panels on solar farms. The Solar Energy Industries Association says solar farms will use about 20 gallons (91 litres) per megawatt hour for cleaning. According to FreeingEnergy, 1MegaWatt (MW) of solar power will farm will produce 2,146 megawatt hours (mwh) per annum. So, it can be expected that a 50MW solar farm will produce about 107,300 mwh pa. This equates to 107,300 (mwh) x 91 (ltrs) = 9.7 million litres per clean. RES say the panels need cleaning every 26 weeks which equates to nearly 20 million litres of water per annum!
One of the reasons solar farms are best suited to brownfield sites is that these locations are not subject to the same volume of dust generated by the normal agricultural activities of ploughing, cultivating, seed drilling and harvesting. The dustier the environment the more frequently it requires to be cleaned, using water.
Add to this, issues of water management ie drainage, and the impact on local watercourses and the wildlife using them.
The solar industry will argue that agriculture uses water too. It does, but for growing food not hedges and not for cleaning acres of panels.
