The UK energy market is entering a period of structural change.

In 2025 alone, more than 200,000 new residential rooftop solar systems were installed across the UK. At the same time, the number of installation companies has grown to well over 2,600 businesses, and that number continues to rise.

This growth isn’t happening in isolation. Globally, solar is moving through what many analysts describe as its second major wave of adoption.

The technology itself is no longer experimental or niche. Solar PV has become a proven, widely accepted form of power generation, and governments around the world are increasingly investing in energy security and domestic generation capacity. As a result, global solar capacity is expected to expand dramatically over the coming years, with forecasts suggesting that installed solar generation could almost triple between 2022 and 2027, making it the largest source of electricity generation worldwide.

In practical terms, this means solar is no longer just an environmentally motivated upgrade.

It is becoming a core part of how modern homes generate and manage energy.

Homeowners are making practical decisions about energy stability, long-term electricity costs, and reducing reliance on volatile energy markets. When prices spike, enquiries surge. When prices stabilise, the companies with strong customer acquisition systems continue to grow while others slow down.

From our perspective at Orvanti, the direction is clear.

Homes are gradually becoming small-scale energy producers. Solar generation, battery storage, EV charging and wider home electrification are beginning to merge into a single ecosystem.

What used to be considered a specialist retrofit is slowly becoming standard home infrastructure.

For a company focused on customer acquisition systems, conversion infrastructure and enquiry generation, this makes renewable energy one of the most compelling sectors to build around over the next decade.

Solar installers sit directly at the centre of that shift.

The UK Solar Industry in 2026

Strong Demand, Increasing Competition

Demand across the UK remains strong, but the industry is no longer the early-stage gold rush it once was.

In many regions there are now multiple installers competing for the same homeowner enquiries, particularly where comparison platforms distribute leads to several companies simultaneously.

Most installers we speak to are not struggling because demand has disappeared.

They are struggling because lead quality has deteriorated, or because their enquiries come from marketplaces where price becomes the main differentiator.

The companies continuing to grow tend to share one simple advantage.

They generate direct enquiries through systems they control, rather than relying entirely on third-party lead platforms.

What a Typical Residential Solar Installation Looks Like

Across the UK, residential systems have settled into a fairly predictable range.

A typical three-bedroom home often installs a 3–5 kW system, usually between 8 and 14 panels depending on roof space and orientation.

System prices commonly fall between £6,000 and £9,000, with batteries adding several thousand pounds depending on storage capacity.

What has changed significantly over the past few years is the role of the battery.

Where storage used to be an optional upgrade, it is increasingly becoming central to the conversation. Homeowners are less interested in exporting energy for small SEG payments and more interested in keeping the electricity they generate themselves.

Technology Is Improving Quietly

Solar technology tends to evolve gradually rather than through dramatic breakthroughs.

Panel efficiencies have steadily improved, with most modern modules comfortably exceeding 20% efficiency. Installers commonly work with manufacturers such as JA Solar, Jinko, Longi or Trina.

In reality, panel efficiency is rarely the limiting factor on residential projects.

Roof space usually determines system output more than anything else.

This is why installers increasingly favour high-efficiency monocrystalline panels that maximise energy production from limited roof area.

The same pattern applies to inverter systems.

Whether installers prefer SolarEdge optimisers, Enphase microinverters, or more traditional string inverter systems, the choice usually comes down to roof layout, shading conditions and monitoring preferences rather than headline performance differences.

For most homeowners, the important factors are reliability, monitoring and warranty coverage.

Battery Storage Is Changing the Conversation

Battery adoption is one of the biggest behavioural shifts in the residential solar market.

Systems such as Tesla Powerwall, GivEnergy and Fox ESS have made home energy storage far more accessible.

Instead of exporting excess energy during the day, households can store electricity and use it during evening peak demand.

This changes how customers think about solar.

The conversation is moving away from simply calculating export income and toward energy independence and resilience.

For many homeowners, the idea of reducing reliance on the grid is just as compelling as the financial return.

Export Tariffs Still Matter

But They’re No Longer the Main Driver

The Smart Export Guarantee still plays a role in system economics.

Export payments typically range between 5p and 15p per kWh, depending on the supplier.

However, these payments rarely drive the decision on their own.

Most homeowners now focus on maximising self-consumption, which is another reason battery storage continues to gain traction.

The Lead Generation Problem Most Installers Mention

When we speak with solar installation businesses, the biggest operational challenge is rarely installation capacity or technical expertise.

It is lead quality.

Platforms such as Checkatrade, Bark and GreenMatch can generate enquiries, but those enquiries are often distributed to multiple installers at once.

This dynamic almost always pushes conversations toward price competition rather than service quality.

Typical costs for shared solar leads in the UK market often fall between £150 and £300 per enquiry.

Many installers are now actively trying to move away from this model by building direct enquiry pipelines, where potential customers contact the company directly rather than through a comparison platform.

Solar Sales Still Follow a Structured Process

Unlike many other home services, solar installations rarely convert immediately after the first enquiry.

Most projects follow a process:

1. Initial enquiry

2. Qualification call

3. System design and proposal

4. Site survey

5. Installation scheduling

From first enquiry to installation, the process typically spans two to six weeks depending on survey availability and scheduling.

Installers with strong follow-up systems and structured proposals usually convert far more enquiries than those relying on quick quotations alone.

A Few Extra Installations Change the Business

Solar installations are high-value projects.

Residential systems often sell between £7,000 and £9,000, and depending on system configuration installers may see £1,500 to £3,000 in gross margin per project.

For teams completing three to five installations per week, even a small increase in monthly enquiries can significantly change overall profitability.

This is why many installers are now focusing on building predictable enquiry pipelines rather than relying solely on referrals or lead marketplaces.

Where the Industry Is Heading

Over the next few years, the solar sector will likely continue merging with other parts of the home energy ecosystem.

Solar installations are increasingly paired with:

• EV charging systems

• battery storage

• home electrification

• heat pump installations

The broader direction is clear.

Homes are gradually moving toward full electrification and decentralised energy generation.

At the same time, some regions are already beginning to experience grid export limitations, which will make battery storage even more valuable in the long term.

Why This Matters for Solar Installers

In a growing industry, the companies that win are rarely the ones waiting for enquiries.

They are the ones building systems that generate them consistently.

Technical expertise will always matter.

But in a competitive market, the installers who combine great installation work with reliable demand generation will almost always outperform those relying purely on marketplaces or word-of-mouth.

That’s exactly where we see the opportunity.

Why We Are Focusing on Solar

At Orvanti, we specialise in customer acquisition systems, conversion infrastructure and enquiry generation for service businesses.

Solar companies and solar installers in the UK are one of the industries where those systems make the biggest difference.

Our goal is simple.

Help installers build predictable enquiry pipelines so they can focus on installations, team growth and delivering high-quality energy systems.

Because as the industry expands beyond 3,000 installation companies, the installers who build reliable demand systems will be the ones who continue to grow.

And in a market as important as renewable energy, those are exactly the companies we want to work with.
