(2) 4-10kWp - UK Solar PV Installation Cost Analysis April'13-March'17

So, you're interested in installing solar PV, but don't know what it's likely to cost?, or possibly already have received quotations and looking for a reliable source to validate whether it's likely to be competitive?, or maybe there's an interest in how prices have moved since your own install?, or even a need to conduct research into the renewable energy sector?

Utilising data tables available from the latest spreadsheets published by BEIS (25/05/2017) it's possible to analyse Solar PV installation costs for all installations registered within the four financial years running from April 2013 through to March 2017.

The above chart details installations per month and the average cost per kWp of installed capacity for registered systems ranging from 4kWp to 10kWp and is based on a data subset sample size of 9500 installations.

The chart clearly shows the rate of system installation growth and the relative fall in costs prior to FiT scheme review changes taking effect on 15/01/2016, modifying both the scheme structure and applying major reductions to available tariffs. Following these scheme changes installation demand saw a dramatic reduction, with a general levelling out of average prices in the period since the early 2016.

It must be noted that the above chart applies to installations rated between 4kWp & 10kWp, therefore a reasonable dilution of cost elements, such as inverters and scaffolding, across the total installed capacity exists. It is therefore reasonable to deduce that the chart more accurately represents the cost/kWp across the entire capacity band than would be the case within the sub 4kWp band.
