Daytime versus evenings
A home occupied all day has different solar economics from one that uses most electricity after 6 pm.
01 / RESIDENTIAL SOLAR
Solar that fits when you use power.
Your panel count is only one part of the design. We balance useful production, roof direction, inverter output, shading and your future plans.
SIZING IN THE REAL WORLD
What we look at before proposing a system.
These considerations come from real customer proposals, not a generic kW-per-person rule.
Roof directions + strings
A mix of east, north and west panels can spread generation through the day. Very short strings can need different design or optimisers.
Inverter headroom
A 10 kW array paired with a 5 kW inverter does not deliver 10 kW AC to household loads at once. A battery compatible hybrid may handle DC energy differently.
Tomorrow’s appliances
Ducted air conditioning, an EV and planned battery storage can substantially change the ideal system.
EXAMPLES FROM OUR PROPOSALS
A familiar roof. Different sensible starting points.
Illustrative proposal configurations sent by SunDrop. They are not advertised packages or guaranteed fits.
6.65 kW14 × 475 W panels. A practical starting point for smaller solar-focused homes; often paired with a 5 kW inverter.
10.45 kW22 × 475 W panels. Considered for higher day loads, more roof coverage or potential battery/EV use.
13.3 to 15.3 kWRecent options used 28 × 475 W or 30 × 510 W panels when larger loads and battery charging warranted it.
Actual system suitability, phase/export rules, panel layout and inverter approvals are site-specific. A smaller array may be the better economic choice.
OUR SOLAR PRODUCT GUIDE
We pay attention to the brand behind the warranty.
The 2026 guide puts Jinko, Trina, JA Solar, LONGi, Canadian Solar, Risen, Suntech, Axitec and Seraphim in the value category. Premium panel options include Aiko, REC, SunPower, Winaico, Tindo and Phono Sumec.
For inverters, we often use GoodWe for a sensible value proposition and discuss Sungrow, Fronius, Sigenergy, SMA, SolarEdge and other premium approaches where their features make sense.

Why we sometimes choose three directions.
One proposal used ten panels east, six north and six west. The objective was a more balanced generation day: morning production, strong midday contribution and a later afternoon shoulder.
Another site had space for only four north-facing panels. Rather than add a short string without investigation, we discussed string voltage and the possible need for optimisers. The right answer depends on the module and inverter specifications.

SOLAR QUESTIONS
Before you sign.
Should I just fit as many panels as possible?+
Not automatically. We model your consumption pattern, available roof faces, inverter capacity and network conditions. More panels can be valuable for charging a battery but will not automatically increase AC inverter output.
Can I add a battery later?+
Yes, often. If you are confident about a compatible DC battery soon, a hybrid inverter may be worth the upfront premium. If not, a standard string inverter can still be combined with an AC-coupled storage system later.
What if one roof face fits only three or four panels?+
That can be difficult for standard string voltage requirements. We check the exact module and inverter operating windows, MPPT arrangement and whether optimisers or a different layout make more sense.
Will my bill become zero?+
We do not promise that. Network supply charges, evening or overnight loads, seasonal output and future usage all affect the remaining bill.
