TQ2081 : Solar PV panels, display of 12 months output

Solar PV panels, display of 12 months output
Solar PV panels, display of 12 months output
The display shows month by month the output from an array of ten solar panels. Nominal peak output is 2.4kV, at times of bright sun and white clouds the output has been up to 2.5kV. The output on the first day of operation is shown in TQ2081 : Installation of solar PV panels - display. The total output shown on the display is for a year and two days; the display integrates readings taken every ten minutes and the output shown directly measured by a meter was 2429 kWh, slightly higher. The rather odd weather this year resulted in generation in each month from March to September being about the same, around 240 kWh, whereas we would expect June and July to show the highest output. However the total is within 1% of that predicted by the installers for a year's output.
Installation of solar PV panels

This series of photographs shows the installation of solar photovoltaic (PV) panels on a semi-detached house. The job was completed in one day by two electricians working inside, and two installers working on the tiled roof. The first stage on the roof is installation of support bars, so there is an air space between the solar panels and the tiles. The panels are installed and their DC output taken through into the loft, where an inverter produces AC. The cable from the inverter goes down through the house to the meter cupboard, where a generation meter and isolating switches are installed. The contractor was Treadlighter Ltd, chosen on a recommendation in Which? Local; they employed Ecovolt to install the panels. The system has a rated peak output of 2.4 kW; on the first day of operation, at the end of September, the peak output was 1.84 kW. A display unit connected by Bluetooth to the inverter shows the history of generation. One thing this showed was the major impact of any shadow; as the shadow of the chimney came onto the panels at 4 pm the power output dropped suddenly.
