Wired motors and solar motors
Updated
Wired motors are the right answer when the panel would sit in shade, when you are already replastering, or when several large curtains would rather share a proper supply. Solar motors are the right retrofit when the box sees the sky and you do not want a new circuit.
What the wall will allow
They are not a moral victory, just a different cable.
A worked pane
The worked opening for Wired motors and solar motors is 3.2 m wide by 1.5 m high, 4.8 square metres of glass. This figure puts 470 watts per square metre on the pane and uses a g-value of 0.7, about 1579 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 237 watts and keeps about 1342 watts out. That is a noon figure for comparison. An internal blind does not get the same reduction. For Wired motors and solar motors, use the noon figure to compare two openings on the same house, then let a measured survey replace the figure.
An internal blind does not get that reduction, because the energy has already crossed the glass.
After dark
Winter figure for Wired motors and solar motors: glass at 1.4 W/m2K, 4.8 square metres, a 12 degree inside-outside gap and eight night hours. The bare pane is about 0.65 kWh a night on that crude sum. A closed shutter cutting about 24 percent of the flow leaves 0.49 kWh and saves about 0.15 kWh a night, only while it is down. Open it when you want winter sun.
Stop conditions
Stop Wired motors and solar motors if the only place for the box is a listed street front and nobody has written advice from the council. A photograph is not a manufacturing size.
London is only a setting for Wired motors and solar motors. The streets there are not the product.
How to use the figure
The 3.2 by 1.5 metre opening inside Wired motors and solar motors 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 £4,096. 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 Wired motors and solar motors, 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. Wired motors and solar motors covers one kind of opening. The house may have three.
When I would not order yet
Wired motors and solar motors 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 Wired motors and solar motors 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. £4,096 illustrates Wired motors and solar motors for a 3.2 by 1.5 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 4.8 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 Wired motors and solar motors 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. Wired motors and solar motors uses a wired motor in the example so you can see how much the motor choice moves £4,096.
