Designed for your roof. Sized for your bill.
JJ Electrical designs each solar array around your roof's actual pitch, orientation, and shading — not an industry average. Real output from real Sydney conditions.
Precision sizing, not panel counts
We map shading across every hour of the year, measure your roof's true azimuth, and size each string to eliminate clipping losses. The result is a system that performs in overcast Sydney winters, not just clear-sky estimates.
Panel selection is matched to your roof's load tolerance and your household's consumption profile — high-efficiency modules where they earn their cost, standard-tier where they don't.
Systems built on real roofs
Accreditation you can verify
Government rebates, zero paperwork
Every install is carried out under a current Clean Energy Council accreditation. Your system qualifies for network grid connection and meets Australian Standards AS/NZS 5033.
JJ assigns your Small-scale Technology Certificates at point of sale, reducing your upfront cost directly. You don't file a form — the saving comes off your invoice.
