November 3rd to December 3rd -2025-The total power consumption to heat the house excluding water heating was 184.11 KWh which equates to approximately 6 kwh per day to heat the house to the slightly higher temperature of 22 degrees in the main living area and the dining/kitchen room to 24 degrees 24 hours a day.

Solar PV generated November =60kwh from the 3kw pv system.

December 3rd to January 3rd -2026- The total power consumption to heat the house excluding water heating was 232 KWh which equates to approximately 7.73 kwh per day to heat the house to the slightly higher temperature of 22 degrees in the main living area and the dining/kitchen room to 23 degrees 24 hours a day. The total for the space heating season is 416kwh to date.

Solar PV generated December =32kwh from 3kw pv system.

January 3rd to February 3rd -2026- The total power consumption to heat the house excluding water heating was 286 KWh which equates to approximately 9.53 kwh per day to heat the house to the slightly higher temperature of 22 degrees in the main living area and the dining/kitchen room to 23 degrees 24 hours a day.

Solar PV -from January 3rd to February 3rd the 3kw system generated 45.4KWh which equates to about 17% of the energy for heating the house if all the solar was used for home heating .

Updated on the 5th March -2026

February 3rd to March 3rd-2026- The total power consumption to heat the house excluding water heating was 205 KWh which equates to approximately 6.8kwh per day to heat the house to the slightly higher temperature of 22 degrees in the main living area and the dining/kitchen room to 23 degrees 24 hours a day.

Solar PV -from February 3rd to March 3rd the 3kw system generated 87.5KWh which equates to about 40% of the energy to heat the house if all the solar was used for home heating . Half of the solar PV installation is pointed North at an angle of 12 degrees. The other half of the PV system is mounted flat (3 degress) , south and shaded .

Updated on the 3th April -2026

March 3rd to April 3rd-2026- The total power consumption to heat the house excluding water heating was 147 KWh which equates to approximately 4.9kwh per day to heat the house to the slightly higher temperature of 22 degrees in the main living area and the dining/kitchen room to 23 degrees 24 hours a day.

Solar PV -from March 3rd to April 3rd the 3kw system generated 253kWh which was greater than that to heat the house if all the solar was used for home heating . Half of the solar PV installation is pointed North at an angle of 12 degrees. The other half of the PV system is mounted flat (3 degress) , south and shaded .

Updated on the 3th May -2026

April 3rd to May 3rd-2026- The total power consumption to heat the house excluding water heating was 14KWh ( a significant reduction) which equates to approximately 0.46kwh per day to heat the house to the slightly higher temperature of 22 degrees in the main living area and the dining/kitchen room to 23 degrees 24 hours a day. The air to air heat pump was mostly off as the winter solar gain took over in heating the house. At some stage I will add the daily temperature readings inside and outside the house to show the actual temperature changes.

Solar PV -from April 3rd to May 3rd the 3.6 kw system generated was 479 kWh which was greater than that to heat the house if all the solar was used for home heating . Half of the solar PV installation is pointed North at an angle of 12 degrees. The other half of the PV system is mounted flat (3 degress) , south and shaded . Two extra 300w panels were added using the enphase micro inverters system. 1.2 kw of the solar installation is shaded by a tree and shrubs early and late in the afternoon.
