Intermittent Electricity From UK Solar PV Costs 3.78X More Than Nuclear !

There isn't a decent sized solar farm in the UK where the information is available on both cost and electricity generated.

Turn to France and we've got it all:

Calculating the Output of a 300 MW Plant in the UK: 

2012: 1,736 MW delivered 1,328 GWh
So 300 MW would deliver 229.5 GWh

2013: 2,822 MW delivered 2,015 GWh
So 300 MW would deliver 214.2 GWh

2014: 5,228 MW delivered 3,931 GWh
So 300 MW would deliver 225.6 GWh

  2015: 8,915 MW delivered 7,556 GWh
So 300 MW would deliver 254.3 GWh
Statistics Section - Table
Average of 229.5 + 214.2 + 225.6 + 254.3
 = 230.9 GWh/year

Reasonable Life Expectancy of a Solar Array to fall to 80% efficiency - 30 years     Source

The average over 30 years of delivery would be 90% of 
the 230.9 average value: 230.9 x 0.9 = 207.8 GWh/year

Delivery over 30 year Life Expectancy = 6.234 TWh

Exchange Rate 2014: GBP/USD - 1.6$ to the £     Source

So 2014 cost of 300 MW UK Plant = £281.25 million

Comparative Data: Hinkley Point C Nuclear Power Plant

Source 1 - Page 15          Source 2

Delivery over 60 year Life Expectancy = 1,513.7 TWh

1,513.7 ÷ 6.234 = 242.8
242 Cestas-sized Solar Parks would have to be built
to deliver the same amount of electricity !

242 x 281,250,000 = 68,062,500,000
242 Cestas-sized Solar Parks would cost £68 billion !

£68 billion ÷ £18 billion = 3.78

For the same capital expenditure nuclear power will deliver nearly 
4X more 24/7 electricity 
than the intermittent electricity delivered by Solar Parks
--------------------//--------------------
242 x 2.5 = 605
242 Solar Parks would cover 605 square kilometres.

Solar Parks just about covering the 
Pembrokeshire Coast National Park !

  1. Good assessment. NOW include the cost of the battery pack needed to actually averge out the solar power. I will even let the solar battery only be required to fit the demand form factor.
