What Beam Solar checks
Every signal that shapes your numbers.
Each one feeds into your indicative system, savings and payback range.
Roof size & direction
How much usable roof you have and which way it faces.
Shading
Trees, neighbouring buildings and terrain that block sunlight.
Roof pitch & tilt
How steep your roof is, which affects how much power it can generate.
Monthly power use
From your bill amount, how much power you use shapes the right system size and savings.
Household size
Used to sense-check your power use when sizing the system.
EV, pool, spa, heat pump
Major appliances change the case for system size and how much you self-use.
Daytime usage
Whether you're home during the day, which drives how much solar you use vs sell.
Export tariff
What you earn selling surplus power back to the grid.
Finance assumptions
Cash, green loan or mortgage top-up, each changing payback materially.
Installer availability
Which vetted installers cover your suburb.
Imagery confidence
How recent and high-quality the satellite imagery is, which sets the confidence on your estimate.
Indicative payback
An honest range, not a magic number, with assumptions shown.
Economics & finance
The funding method matters, whether cash, loan or mortgage top-up.
Beam Solar shows a range, not a magic number, and how different funding choices change your payback. Your return also depends on how much power you use at home versus export to the grid.
Cash purchase
Best lifetime return. Capital tied up. Fastest payback when self-consumption is high.
Green home loan
Several NZ banks offer low- or zero-interest top-ups for solar. Payback depends on the rate.
Mortgage top-up
Spread the cost over your home loan. Lower monthly impact, more interest over time.
Export vs self-use
Power used at home is worth far more than what you export, so daytime usage drives your return.
Why Beam Solar exists
Solar quotes are confusing. Beam Solar makes the first step simple.
Most homeowners get three quotes from three installers, with three different system sizes, three different prices, three different sets of assumptions. Beam Solar gives you an independent, property-specific read on your own numbers first, so you understand your options before anyone pitches you.
Every home is different
Roof size and direction, shading, and how you use power all affect the case. Beam Solar's check is the same regardless of who you'd buy from.
Installer quotes vary widely
System size, panel quality, inverter choice, install method and finance terms all differ, which makes comparing them hard.
Savings depend on a lot
How you use power, your roof direction, system size, export rates and finance all compound. A simple "$X per month" pitch hides assumptions.
You deserve the numbers first
Beam Solar shows you indicative economics before you talk to anyone, so you understand your own numbers going in.
