Why Choosing an Experienced Solar Installer Matters

A Real Example of the Risks of “Cheap” Solar Quotes

At The Green Way Solar, we often speak with homeowners who have received multiple quotes for their solar installation. While it’s natural to compare prices, choosing the cheapest option can sometimes lead to serious issues, particularly when installers lack the experience or knowledge required to meet UK regulations.

Recently, a prospective customer contacted us after a frustrating experience with another installer.

They explained that they had initially chosen a competitor because of a slightly lower price. However, after several weeks of discussions and planning, it became clear that the proposed installation did not comply with the UK’s G99 grid connection standards. This meant the system could not legally be installed or connected to the grid without major changes.

Unfortunately, this resulted in weeks of wasted time, delayed plans, and the need to start the process again with a qualified installer.

Situations like this highlight why experience, accreditation, and technical expertise are critical when choosing a solar company.

Understanding G99 Compliance

In the UK, larger solar installations must comply with G99 regulations, which govern how generation systems connect to the electricity grid.

These rules ensure that solar systems operate safely and do not disrupt the wider electricity network.

A compliant system requires:

Proper system design and inverter configuration
Correct DNO (Distribution Network Operator) applications
Accurate export calculations
Professional electrical design and commissioning

If these steps are not followed correctly, installations can be rejected by the DNO, preventing the system from being connected to the grid.

Why Experience Makes the Difference

At The Green Way Solar, our team handles G98 and G99 applications regularly and understands the technical and regulatory requirements involved in designing compliant solar systems.

We ensure every installation is:

✔ Fully MCS compliant
✔ Designed with DNO approval in mind
✔ Installed by qualified electricians and experienced installers
✔ Supported with complete handover documentation and certification

This approach avoids delays and ensures customers receive a system that works efficiently, legally, and safely from day one.

The True Cost of Choosing the Wrong Installer

Solar installations are a long-term investment, often expected to last 25+ years. Choosing an installer purely on price can lead to:

Non-compliant system designs
Delays with grid approval
Poor installation standards
Limited aftercare and support

In many cases, homeowners end up spending more time and money correcting problems than if they had chosen an experienced installer from the start.
