A home solar system is sized around how your household uses power, not around how much roof you have. NG Elec handles residential solar panel installation across Adelaide and the surrounding council areas, for first-time installs and for homes replacing or expanding an ageing array.
Panel choice, inverter quality, shading and the time of day you use the most power all shape what a system returns. Those decisions are made before anything reaches the roof.
Size is a usage question before it is a roof question. A household that runs air conditioning through an Adelaide summer afternoon, charges an EV overnight, or works from home has a very different load shape to one that is empty between 8am and 5pm, and the right residential solar panel system follows that shape.
We start with 12 months of billing data and, where the meter allows, interval data showing when power is actually drawn. That tells us how much generation you can use yourself, which is worth far more than what gets exported. From there, we model the panel count against the usable roof area, the orientation of each roof face, and any shading from trees, gables or a neighbouring two-storey home.
North-facing panels give the highest total output, while a split east and west layout spreads generation across the morning and late afternoon, which suits households that use power at both ends of the day. Most Adelaide roofs end up with a mix. The inverter is then matched to the array, with a little headroom left where an expansion or battery is likely later.

20 Years of Experience
When considering home solar installation cost, adding storage at the same time as the panels is usually cheaper than retrofitting, because one design, one attendance and one set of electrical work covers both. Doing solar first still makes sense when the budget is tight, provided the inverter and switchboard are chosen with future storage in mind.
What to weigh up | Battery now usually suits | Battery later usually suits |
Evening power use | Most of your usage sits after sunset | The house is busiest through the middle of the day |
Budget | You can fund both in one project | You want panels working while you save |
Backup power | You want the house supported through an outage | Outages are not a concern |
Install cost | One attendance covers both | Accepting a second install later |
The trap in going later is hardware. A string inverter chosen without storage in mind can force either a second inverter or a replacement when the battery arrives, so we specify a hybrid or battery-ready setup whenever storage is on the table at all.
A solar system is a 20-year asset with moving parts in the electrical sense, and output can drift when panels get dirty, a string drops out or an inverter fault goes unnoticed. Monitoring catches most of that, which is why we set it up with you rather than leaving it in the box. For residential solar installation in Adelaide, ongoing monitoring and servicing help keep the system performing as expected.
Our workmanship carries a lifetime warranty, the equipment carries its manufacturer warranty, and scheduled maintenance attracts a discount. If output drops, the same team that installed the system comes back to it, and we also service and repair systems installed by other companies, including insurance work after storm or hail damage.
