The Future of MCS...

[TedM]

Digging deeper at https://www.gov.uk/government/publi...eature-article-small-scale-solar-pv-cost-data regarding the methodology for that data it says:

Each record contains one cost figure for the installation which is defined as follows:

“Cost of solar photovoltaic generation equipment, plus direct costs of fixing panels to roof/ground mount, any performance displays and connecting to electricity supply, including VAT but excluding (a) the cost of any extended warranty; and (b) the cost of other materials, works or other items whatsoever (such as, but not limited to, any cost of general rewiring at a property or tracker systems).”

It should be noted that the data are therefore wholesale costs and do not represent the cost that the householder has paid for the installation.

Does anyone enter "wholesale" costs in to the MCS database?

Also if you look at data in Table 2 in that report it is obviously complete nonsense.
