An example Beam assessment: your roof, likely system size and savings, before you talk to anyone

Getting solar quotes in Auckland should not begin with filling in 3 basic forms on 3 different installers' sites.

It should begin with one simple question:

Does solar actually stack up for your home?

The answer depends on far more than your power bill. Your roof shape, direction, shade, daytime electricity use, future EV plans and likely export rate all matter. Two homes on the same street can have very different solar outcomes.

Roof by roof

Two homes, same street, different outcomes

14 Maple Street

Well suited

North-facing · unshaded · 6.4 kW system

16 Maple Street

Less suited

South-facing · tree shade · marginal case

Beam checks orientation, shade and roof size for your exact address before anything else

That is why Beam Solar starts with the property, not the installer.

We assess your address, roof layout, likely solar potential and energy use to give you a clearer view of what may make sense before you spend time on a site visit, a sales call, or trying to find a reliable installer.

The problem with comparing solar quotes

Most people do it backwards.

They collect two or three quotes, see different panel brands, different system sizes and different savings claims, then try to work out which one is "best" (usually the cheapest one).

The cheapest quote is not always the cheapest system.

A lower upfront price can mean fewer panels, lower production, weaker warranties, less attention to roof layout or assumptions that look good on paper but do not match how you actually use power.

Indicative comparison. Every quote is confirmed by the installer

We get quotes for you and make them easy to understand:

  • how many panels are proposed, and why;
  • where they will sit on your roof;
  • how much electricity the system is expected to generate;
  • how much of that electricity you are likely to use yourself;
  • what will be exported back to the grid;
  • the panel, inverter and workmanship warranties;
  • what is included, excluded or subject to a site visit.

If those things are unclear, you are not really comparing like with like.

What Beam checks before you speak to an installer

Beam gives Auckland homeowners a property-specific starting point.

Using your address and an aerial roof assessment (LiDAR where Auckland has it, satellite imagery where it doesn't), we look at things such as roof area, orientation, likely panel capacity and local solar conditions. You can then add your energy use and future plans, such as an EV, battery or changing household size.

The result is a clearer picture of:

  • whether your roof is likely to suit solar;
  • a sensible starting system size;
  • expected generation and likely savings;
  • how long the system may take to pay back;
  • whether solar looks worthwhile before you spend time chasing quotes.

Shifting big loads to daytime lifts self-use, and self-used solar saves more than exported solar.

Self-used solar saves more than exported solar

It is not a binding installer quote. A proper site visit still matters. But it gives you, and the installers, a much better base from which to make a decision.

Three questions to ask every solar installer

Before accepting a quote, ask these:

  1. Why is this the right system size for my house? A bigger system is not always better. The right size depends on your daytime use, roof capacity, export rate and future plans.
  2. What assumptions sit behind the savings estimate? Ask how much electricity they assume you will use yourself, what export rate they have used, and whether the projection reflects your actual usage.
  3. What could change after the site visit? A good installer should be clear about anything that may affect price or design once they inspect the roof, switchboard and cable routes.

Simple questions, but they separate a considered proposal from a sales estimate.

Before you accept any quote

3 questions to ask every solar installer

1

Why is this the right system size for my house?

Size should match your daytime use, not just roof area.

2

What assumptions sit behind the savings estimate?

Ask the self-use rate and export price they've assumed.

3

What could change after the site visit?

Price and design can shift once they inspect the roof.

Start with your roof, not the sales call.

Solar may not be right for every Auckland home

Solar can be excellent, but it is not magic.

Our promise

Solar isn't right for every roof.

Heavy shade, a small or ageing roof, or low daytime use can all make solar a poor fit. When that's true, we'll tell you. A smaller system, a different design, or waiting might be the honest answer.

It may be less attractive where a roof is heavily shaded, too small, due for replacement soon, or where the household uses very little electricity during the day. In those cases, the right answer may be a smaller system, a different design, or waiting.

We would rather show you that honestly than make solar look good on every house.

A better way to get solar quotes in Auckland

With Beam, you can understand your roof and likely numbers first.

No pressure. No need to hand your details to multiple companies just to find out whether solar is even worth considering.

When you are ready, you can choose whether to speak with an approved installer. Your details are only shared once you decide.

Beam Solar is an introduction platform, not an installer. Online assessments are indicative only and are confirmed through an installer's site visit and final quote. Solar outcomes vary by roof, energy use, electricity plan and system design.
