As energy prices soar and climate awareness grows, more UK homeowners are turning to renewable energy. One of the most effective ways to make your home more energy-efficient and reduce your carbon footprint is by installing domestic solar panels. But with so much information out there, it’s essential to understand what you’re getting into. In this guide, we cover everything you need to know about home solar panels: from choosing the right size to understanding costs, returns, and whether they’re truly worth it in the UK.

What Are Home Solar Panels?

Home solar panels, also known as household solar panels or house solar panels, are photovoltaic (PV) systems that convert sunlight into electricity. This electricity can power your household appliances, lighting, and even heating systems, helping you rely less on the grid and more on clean, renewable energy.

Modern systems are sleek, efficient, and more affordable than ever. With advances in technology and financial incentives available, solar energy is now accessible to a wider range of homeowners.

Are Solar Panels Worth It in the UK?

You might be wondering, “Are solar panels worth it UK homeowners?” The answer, in most cases, is yes.

While the UK may not be known for endless sunshine, solar panels don’t need direct sunlight to generate electricity; just daylight. Even on cloudy days, panels can produce a surprising amount of energy.

Here are a few reasons why they’re a solid investment:

• Lower energy bills: Generate your own electricity and reduce what you buy from the grid.
• Return on investment: You can benefit from the Smart Export Guarantee (SEG), which pays you for the electricity you export back to the grid.
• Property value: Homes with solar panels often sell for more and attract eco-conscious buyers.
• Sustainability: Lower your carbon footprint and contribute to a cleaner future.

How Many Solar Panels Do I Need?

This is one of the most common questions we’re asked: How many solar panels do I need?

The answer depends on several factors:

• Your energy usage: A typical UK home uses around 3,100 kWh per year.
• Roof space: Larger roofs can accommodate more panels, increasing output.
• Orientation and shading: South-facing roofs without obstructions are ideal.
• Panel efficiency: Newer models produce more power with less space.

As a rule of thumb, a 3kW system (about 8–12 panels) suits a small household, while a 4kW to 6kW system is better for a larger family home.

At Thompson Renewables, we offer personalised assessments to determine the ideal system size for your home.

Understanding Solar Panel Sizes

Solar panel sizes can vary, but standard residential panels are typically around 1.6m x 1m. Their power output ranges from 300W to 450W per panel.

Choosing the right solar panel sizes for your home depends on:

• Available roof space
• Energy requirements
• Budget
• Desired return on investment

For homes with limited roof space, higher-efficiency panels may be worth the extra cost.

Installation Process: What to Expect

Here’s what the typical installation process looks like:

1. Consultation & Survey: We assess your property and energy usage to recommend the right system.
2. Design & Proposal: You’ll receive a detailed plan outlining the number of panels, layout, cost, and expected returns.
3. Installation: Our certified technicians install the system, usually within 1–2 days.
4. Connection & Monitoring: Once installed, we connect your system to the grid and provide tools to monitor your energy production and savings.
5. Aftersales Support: We pride ourselves on ongoing customer service, offering maintenance and support long after your system is up and running.

Financial Incentives and Returns

Although the Feed-in Tariff (FiT) closed in 2019, the Smart Export Guarantee (SEG) is now available, allowing you to earn money by exporting surplus electricity back to the grid.

Additionally, many households see a return on their solar panel investment within 6 to 10 years, after which the savings continue to grow year-on-year.

And let’s not forget: solar power reduces your dependency on volatile energy markets, helping shield you from future price hikes.

Maintenance and Lifespan

House solar panels are built to last. Most come with a 25-year performance warranty and require minimal maintenance. An annual visual inspection and occasional cleaning are usually sufficient.

At Thompson Renewables, our domestic installations include aftersales support to ensure long-term reliability and performance.
