Sized to your household
We look at your bills and daily routine first. The panel count follows from that.
Residential solar / Harrow & Stanmore
Residential solar in Harrow and Stanmore.
From the 1930s semis around Harrow to the larger detached houses on the slopes of Stanmore, this part of North West London has plenty of homes with generous pitched roofs. REX surveys, designs and installs residential solar and battery storage across HA1 to HA7, starting with the house and how you use electricity.
Your Harrow & Stanmore project
Start with what the property needs.
The useful result is a system you understand: how it fits, what it is expected to generate and where a battery may help.
Roofs mapped before anything is promised
A survey shows which slopes get sun, where chimneys and roof windows cast shade, and what is really usable.
Battery only where it earns its place
If you are out all day, evening storage may help. If not, we will say so.
Planned for the next ten years
An extension, a loft conversion or a new way of living in the house all change demand. We allow for it.
Access and cabling agreed up front
Scaffold positions, inverter location and cable routes are settled before work starts.
Plain numbers
Generation estimates come with their assumptions, so you can see what is behind them.
Local considerations
A closer look at Harrow & Stanmore.
Interwar houses, varied roofs
Harrow is full of 1930s semis and detached houses, many with hipped roofs, bay windows and later loft conversions. Those details decide where panels can go. A south-west and south-east split across two slopes is common, and can suit a household that uses power morning and evening.
Hill streets and mature trees
Harrow on the Hill and Stanmore Hill rise above the surrounding streets, and many roads here are lined with mature trees. A good survey looks at how shade moves across the roof through the day and the year, not just at a single photograph.
Why REX
From the survey to a clear proposal.
Send the address, a recent electricity bill or usage summary, a few photos of the roof and any building plans. We will talk through the survey, the proposed layout and whether a battery fits. The proposal then sets out equipment, expected generation, access and the work included.
Before you decide
Solar questions in Harrow & Stanmore.
Does a semi-detached house have enough roof?
Often, yes. It has less roof than a detached house, so layout matters. We show you how many panels fit and what they are expected to generate before you decide.
Do you cover Pinner and Kenton as well?
We survey and install across the HA postcodes. Send your postcode and we will confirm.
Can I add storage later?
Usually, but it needs a compatibility check. If you might want a battery, tell us now so the design allows for it.
What if my roof needs repair first?
Then repair comes first. Panels go on after the roof is sound, so you are not paying to take them off again.
Is my street in a conservation area?
Harrow Council lists conservation areas in Harrow on the Hill, Stanmore Hill, Pinner and elsewhere in the borough. A conservation area does not automatically rule out solar, but extra rules can apply, so check your address with the council. REX can advise on roof options.

Solar in a conservation area?
A conservation area does not automatically rule out solar. REX can advise on conservation matters and discuss roof options, with consent requirements confirmed by the council or relevant estate.
