== Solar in 2023 ==
 * A pretty much normal year, averaging 374kWh per month net export.
 * See also EcoTaskHomePage#Data2023
{{attachment:UnitedEnergyGraph2022and2023.png}}

== Solar in 2022 ==
 * Again atypical, with some shutdowns and some open windows in winter.
 * United Energy changed their web site, so the graph shows two years and no average.
 * Data download shows that we bought 15689kWh and sold	21659kWh during 2022, averaging 498kWh per month net export.

== Solar in 2021 ==
 * Clearly another atypical year in so many ways.  Average per month is 1243kWh generation.  Near normal operation during much of winter saw increased consumption compared with 2020.

== Solar in 2020 ==
 * Solar panels were installed on 15 Southdown manse in February (See PropertyReport202003) and 17 Southdown.
 * Clearly an atypical year in so many ways after the first two months.  Average generation per month is 1759kWh.  Our usage was comparable to the average home.

== Performance of our solar panels in 2019 ==
 * The 2019 graph shows net generation of 3750kWh, compared to 2436kWh in 2018.  Above the axis is energy bought, below the axis is energy sold, the broken line is the average net per month.
 * PropertyCommittee are progressively replacing lights with more efficient LEDs
  * The office was done last year and men’s and ladies toilets done so far this year, with store rooms underway. Next is the foyer.
 * Plans are underway to get the manses converted to solar. We may not save money, but it will be a big plus for our overall footprint.

== Performance of our solar panels 2017-2018 ==
=== Electrical ===
 * The picture shows usage and generation by month for 2017 and 2018.
 * It can be seen that we became a net generator for 2018. (Net consumption, the broken line, is positive for 2017 but negative for 2018.)
 * The big difference between the two years was the installation of the new heating system in the worship centre, visible as reduced winter consumption.
 * The price difference between buying and selling means that we still pay something for electricity, but much less than we would without the panels.

2016 is incomplete.  The distributor changed their system and we missed some data.
