TQ2081 : Snow slips off solar panels

Snow slips off solar panels
Snow slips off solar panels
The previous evening 8cm of snow fell in a couple of hours. We had thought it would cover the solar panels, but by midnight it had all fallen off the shiny surface. Notice the soft snow still on the myrtle on the right; there was so little wind that the soft snow stuck on the branches.
The panels generated about 180 kwh in October, and about 80 in each of November, December and January.
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.
