Several solar solutions, should I just go with the cheapest option?

When you’ve spoken to multiple solar installers, you’ll likely end up with several quotes and system proposals.

At that point, one question naturally comes up:

Should you just go with the cheapest option?

In reality, price is only part of the picture.

The key is less about who’s cheapest — and more about:

  • Which system actually follows through
  • Which installer carries out a proper survey
  • And who designs the system around your usage, not a template

In this guide, we’ll walk you through the three factors that truly matter before you make a decision.


1. Which System Actually Follows Through

Not all solar systems are built to work seamlessly together. And this is where many low-cost quotes fall short.

Compatibility Between Components

A well-designed system ensures that:

The inverter and battery are fully compatible

Communication protocols between brands are supported

The system can monitor and optimise performance effectively

Some cheaper setups combine components that technically “work”, but don’t fully integrate — leading to reduced efficiency or limited functionality.


2. Which Installer Surveys Properly

A proper site survey is not optional — it’s essential.

What a Good Survey Should Include

A professional installer should assess:

  • Roof condition, angle, and direction
  • Potential shading (chimneys, trees, nearby buildings)
  • Electrical setup of the property
  • Your actual energy usage patterns

Without a proper survey, your system may underperform due to shading issues, or be incorrectly sized, or fail to match your real energy needs

A quote without a detailed survey is often just a guess.


3. Who Designs Around Your Usage — Not a Template

This is where the biggest difference lies between average installers and professional ones.

Many companies use standardised system packages. But your home is not standard.

A Tailored Design Should Consider:

  • Your daily energy consumption
  • Peak vs off-peak usage
  • Future needs (EV charging, battery upgrades)
  • Lifestyle patterns

So… Is the Cheapest Quote Worth It?

Sometimes it is.

But often, it comes with compromises you don’t see at first.

The real question isn’t: “Which quote is cheapest?”

It’s: “Which system will actually deliver what it promises?”
