What Keighley weather does to a conservatory
We ran Keighley's hourly weather for 2024 and 2025 through the same room three times, once per roof. The squares are hour by hour averages. The garden never beat 29.6°C and August averaged 15.9°C, but the polycarbonate room touched 44°C, against 32°C with panels.

The hours you get back
Count only the hours people are awake, 8am to 10pm, and sort them by how the room feels. Cold hours can be fixed with a heater. Too-warm hours mostly cannot, short of opening everything and hoping. That is why the panel roof adds about 920 usable hours a year in Keighley: 4,031 becomes 4,951.
Hours above 30°C drop from 378 under polycarbonate (and 526 under glass) to 8 with panels.

When the heat peaks in Keighley
Under polycarbonate the overheating peaks in July, when 36% of waking hours pass 28°C. With the panel roof the same month sits at 2%. Look at April and September as well: low sun through glass walls still warms the room, but not through the roof any more.

Winter in Keighley
January is Keighley's coldest month, averaging 3.1°C, with a lowest hour of -10°C over the two years. Holding the room at 19°C through waking hours takes about 1,909 kWh a year under polycarbonate (£502 on electric heaters at the 26.32p price cap) and 1,588 kWh (£418) under panels.
That saving is real but modest, because the glass walls still lose heat. The bigger winter change is the heater: on a freezing evening a 1.1 kW heater keeps up under panels where polycarbonate needs 1.7 kW.

Fitting day
Most roofs here take one day, larger or more complicated ones two. The old sheets come off in the morning, the frame is checked, and the panels, ridge or hub and trims go on before the light goes. The fitting day walks through it hour by hour.
