Solar Panel Installation (Domestic & Commercial)
Blackwell & Denton FM Ltd design, install, test and maintain solar for homes, landlords and businesses across York and North Yorkshire. Every job starts with a survey of your roof and your electrics, and ends with a certified system you can actually read, monitor and rely on.
From first survey to a panel cleaned three years later
Solar is not a single product you buy off a shelf, so we treat it as a set of jobs: design it properly, install it watertight, prove it works, then keep it working. Pick what you need, or take the whole thing.
Site survey & roof assessment
We visit first. Roof orientation, pitch, shadowing from chimneys and trees, tile or membrane condition, loft route, meter and earthing arrangement — then we tell you honestly what the roof will and won't support.
System design & output estimate
Panel layout, panel count and inverter sizing worked round your daytime usage, not a generic package. You get the expected annual generation and where the savings actually come from.
Mounting & panel installation
Rail systems for tile and slate roofs, ballasted or fixed layouts for flat roofs, lead flashing and waterproof detailing, cable management that stays out of sight.
Inverter, isolators & consumer unit work
Inverter mounting in the loft, garage or plant room, DC and AC isolators, dedicated overcurrent protection, earthing and bonding, and consumer unit upgrades where the existing board can't take the array.
Battery storage & solar battery systems
Hybrid inverters and retrofit batteries so stored daytime power runs the house in the evening. Backup-ready options where you want resilience as well as savings.
Monitoring & app setup
Live generation, import, export and household usage on your phone, with alerting configured so a dropped string or offline inverter is spotted before a bill is noticed.
Testing, certification & notification
Full electrical tests, Electrical Installation Certificate, Building Control notification and distribution network operator notification where the installation requires it, plus the paperwork kept for you.
Extensions & system upgrades
More panels added to an existing array, an ageing inverter swapped for a current model, single-phase to three-phase commercial designs, and older systems brought back to full output.
Cleaning, maintenance & repairs
Panel cleaning for rooftops that collect pollen, bird fouling or dust from nearby fields, torque and connection checks, thermal inspection, and fault finding on systems that have stopped exporting.
Commercial & industrial arrays
Warehouses, units, offices, farms, garages, schools and care homes. Daytime load makes commercial roofs the best solar in the country, and we plan around your trading hours and shutdowns.
Access, safety & site discipline
Scaffolding, tower or harness access arranged as needed, roof-safety rules followed, dust sheets and walkways protected, and the site left tidy at the end of each day.
Handover & aftercare
A walkthrough of how the system works, what to look for and who to call, with manufacturer warranties passed on to you in writing and our own workmanship covered.
Domestic properties
For households in York, Clifton, Acomb, Driffield, Tadcaster and the surrounding villages: systems sized around what a family actually uses in daylight, with the option to store it or send it to a car.
- Tile and slate roofs, flat-roof bungalows and garages
- Loft, garage or exterior inverter locations, discussed with you
- Battery storage added now or later
- Consumer unit upgrades and extra circuits where needed
- Home EV charging run alongside the solar design
- Cable routes kept tidy and out of sight wherever possible
- Tenanted and HMO properties, with the right certificates
Commercial & industrial
Businesses running motors, fridges, extraction or machinery through the day use exactly what a roof produces, which is why commercial solar pays back fastest. We fit in around your operations.
- Warehouses, trade counters, offices, farms and workshops
- Three-phase arrays sized around your daytime load
- Flat-roof and membrane-safe fixing details
- Metering, CT clamp and export monitoring set up correctly
- Phased installs around production, deliveries and opening hours
- Maintenance contracts and planned inspections included in a facilities plan
- Multi-site and landlord portfolios handled by one team
Six steps, start to finish
Tell us what you want
Call 01904 659066, WhatsApp a photo of your roof, or use the chat. We ask what you're trying to fix: bills, an EV, a warehouse load, or a building that's just never warm enough.
Survey & honest advice
A visit to measure and check the roof, the electrics and the shading. If solar won't pay off on your property, we say so and suggest what would work better.
Design, quote & dates
A written design with panel layout, expected output, everything included and everything excluded. No surprises added on the day.
Installation
Most domestic roofs are completed in one to three days. Commercial work is phased so trading, parking and access keep working while we're on site.
Test, certify & notify
The system is tested, the certificates issued, and the required notifications lodged. You get a copy of everything, not a promise of a copy later.
Handover, monitoring & aftercare
Apps installed and explained, readings checked with you, and a direct line back to us for cleaning, checks, faults or an extension in a few years.
What every installation includes
If your roof is wrong for solar, we will say so
Deep shade, a tired roof that needs re-covering first, or a single-phase supply that cannot take the array you would need — these are all real answers, and you will hear them from us at survey stage rather than after a deposit. Where that happens we will point you at the work that does make sense, whether that is battery storage, an EV charger, better controls or the electrical upgrades we already carry out for facilities contracts.
Solar sits inside our facilities work, not beside it
NICEIC Approved electrical work, Gas Safe heating, appliance repairs, planned maintenance, safety certificates, gutter cleaning and reactive call-outs all come from the same Clifton Moor team. If solar goes on your roof, the inverter, the consumer board, the annual inspection and the fault at two in the morning are all covered by people who already know the building.
