Solar PV — the range
These are the panel makers we design with, what each is genuinely known for, and the numbers that matter — output, efficiency and how long the performance is guaranteed. Your array is designed per roof aspect from the survey and shading assessment.
Aiko
The efficiency leader — all-black N-type modules with the strongest output per square metre of roof.
Smaller or awkward roofs that need every watt from limited space, and homes where the sleek all-black look matters as much as the output.
LONGi
The strong default — top-tier efficiency and output from the world's biggest panel maker, at a sensible price.
Most homes, most roofs — the best balance of efficiency, price and long-term backing in the range.
REC
Longevity — the lowest degradation in mainstream production (~0.25%/yr), still near full output decades in.
Forever homes where total energy over 25+ years matters more than the sticker price — the warranty to beat. *Extended cover applies via certified installation.
Trina Solar
High-power innovation with dual-glass durability — robust panels from a tier-1 volume manufacturer.
Exposed or coastal roofs where the dual-glass build earns its keep, and value-led projects that still want long cover.
JA Solar
Dependable tier-1 output per pound — the value benchmark of the mainstream brands.
Larger arrays where panel count drives the budget — maximum generation for the spend without dropping off the tier-1 list.
Figures are manufacturer-published typical values for current residential modules and vary by exact model and batch. Real-world yield is decided by your roof — orientation, pitch and shading — which is why we design strings per aspect from the survey rather than quoting a one-size array.
Generation is decided as much by the design as the module: strings laid out per roof aspect so a shaded corner never drags down a sunny one, an inverter sized for the array — hybrid-ready if a battery is on the cards — and export set up under the Smart Export Guarantee so surplus earns instead of vanishing.
We handle the DNO notification and paperwork, and qualifying residential installations carry 0% VAT until 2027. Pair the array with a battery, a heat pump or an EV charger and your own generation does the heavy lifting before the grid is touched.
