Somfy solar roller shutter: where it is the wrong buy
Updated
Somfy's public pages say the panel can charge from daylight, not only from hard sun, and that the install stays on the outside. A north wall, a deep soffit or a tree can still starve the panel.
The limit
Somfy's public pages say the panel can charge from daylight, not only from hard sun, and that the install stays on the outside. A north wall, a deep soffit or a tree can still starve the panel. Ask the surveyor to stand where the panel will sit and say whether December light is enough.
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: where it is the wrong buy is 0.9 m wide by 2.1 m high, 1.89 square metres of glass. This figure puts 520 watts per square metre on the pane and uses a g-value of 0.7, about 688 watts into the room if the curtain is up. An opaque external shutter, taken as stopping 85 percent of that gain while it is fully down, leaves about 103 watts and keeps about 585 watts out. That is a noon figure for comparison. An internal blind does not get the same reduction. For Somfy solar roller shutter: where it is the wrong buy, 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: where it is the wrong buy: £1,673 at September 2026 prices, for this 0.9 by 2.1 m opening with a wired motor. 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: where it is the wrong buy: glass at 1.4 W/m2K, 1.89 square metres, a 12 degree inside-outside gap and eight night hours. The bare pane is about 0.25 kWh a night on that crude sum. A closed shutter cutting about 24 percent of the flow leaves 0.19 kWh and saves about 0.06 kWh a night, only while it is down. Open it when you want winter sun.
Stop Somfy solar roller shutter: where it is the wrong buy if the frame cannot take a guide and the wall beside it is crumbling. A photograph is not a manufacturing size.
How to use the figure
The 0.9 by 2.1 metre opening inside Somfy solar roller shutter: where it is the wrong buy 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 wired motor, and the illustration is £1,673. 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: where it is the wrong buy, 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: where it is the wrong buy covers one kind of opening. The house may have three.
When I would not order yet
Somfy solar roller shutter: where it is the wrong buy should wait if the opening is an escape door with no way to raise a dead motor, or if the front is the elevation a conservation area was drawn to protect.
A photograph is not a manufacturing size. Two quotes for Somfy solar roller shutter: where it is the wrong buy only compare when the slat, the box and the drive are the same kind of thing.
Questions worth asking the fitter
Is the price on this page a quote?
No. £1,673 illustrates Somfy solar roller shutter: where it is the wrong buy for a 0.9 by 2.1 metre opening with a wired motor, at September 2026 rates. Your survey replaces it.
Does the shutter cover every pane?
It covers the opening it is built for. Here that example is 1.89 square metres. A roof lantern, a side light or the next elevation is another line.
What if planning is unclear?
Do not pay the factory for Somfy solar roller shutter: where it is the wrong buy until a listed building, a conservation front, a flat or a shopfront has a written answer. Ordinary rear walls on houses are sometimes simpler.
What should two quotes share?
The same openings, the same slat type, and the same drive. Somfy solar roller shutter: where it is the wrong buy uses a wired motor in the example so you can see how much the motor choice moves £1,673.
