Somfy solar roller shutter: a UK fitted illustration
Updated
As a September 2026 illustration, a single domestic window with a Somfy solar drive often sits in the same band as other solar retrofits, commonly somewhere around £900 to £1,800 fitted for an ordinary window, and more when the opening is a wide bifold. The motor premium is real.
The illustration
As a September 2026 illustration, a single domestic window with a Somfy solar drive often sits in the same band as other solar retrofits, commonly somewhere around £900 to £1,800 fitted for an ordinary window, and more when the opening is a wide bifold. The motor premium is real. The saving is the cable you do not run back to the consumer unit.
Openings with no sky on the box, and buyers who think Somfy is the shutter rather than the drive. Also a poor match if you need a tested security rating that Somfy does not certify, because the rating lives on the curtain and the guides.
A worked opening beside Somfy solar roller shutter
The worked opening for Somfy solar roller shutter: a UK fitted illustration is 4.2 m wide by 1.2 m high, 5.04 square metres of glass. This figure puts 620 watts per square metre on the pane and uses a g-value of 0.63, about 1969 watts into the room if the curtain is up. An opaque external shutter, taken as stopping 80 percent of that gain while it is fully down, leaves about 394 watts and keeps about 1575 watts out. That is a noon figure for comparison. An internal blind does not get the same reduction. For Somfy solar roller shutter: a UK fitted illustration, use the noon figure to compare two openings on the same house, then let a measured survey replace the figure.
Fitted illustration for Somfy solar roller shutter: a UK fitted illustration: £3,711 at September 2026 prices, for this 4.2 by 1.2 m opening with a belt. The figure allows a front-mounted aluminium curtain and ordinary fixing. It does not include scaffold, a rebuilt soffit, planning drawings, or a new window. A second opening on the same visit usually costs less than the first, because the van is already there. Compare two quotes only when the slat, the box and the drive match.
Winter still applies
Winter figure for Somfy solar roller shutter: a UK fitted illustration: glass at 1.2 W/m2K, 5.04 square metres, a 12 degree inside-outside gap and eight night hours. The bare pane is about 0.58 kWh a night on that crude sum. A closed shutter cutting about 18 percent of the flow leaves 0.48 kWh and saves about 0.10 kWh a night, only while it is down. Open it when you want winter sun.
Stop Somfy solar roller shutter: a UK fitted illustration if the solar panel would sit in a soffit with no sky, and the quote has no wired alternative. A photograph is not a manufacturing size.
How to use the figure
The 4.2 by 1.2 metre opening inside Somfy solar roller shutter: a UK fitted illustration is there so a quote has something to disagree with. If the tape gives a different size, the tape wins.
The example drive is a belt, and the illustration is £3,711. A belt, a wired motor and a solar motor can share a curtain and still be different jobs. Compare those lines, not a single bold total.
What the survey still has to write down
For Somfy solar roller shutter: a UK fitted illustration, ask where the box lands, what colour reference will be ordered, and how the curtain opens when the motor is dead. Those three answers move the job more than a rounded price.
Leave the lantern, the side light and the next elevation off the order unless they are drawn. Somfy solar roller shutter: a UK fitted illustration covers one kind of opening. The house may have three.
