Choosing the Right Affordable Solar Panel Brand

You might want to consider this - snagging a bargain on those cheap and cheerful solar panels is worth squat if you're not choosing a brand that rings with quality and reputation. Picking the right manufacturer is the real priority here. Not only do they make sure their products will stand the test of time, but when you're stuck in a pickle, their customer support is bang on.

So, here are some things you need to think about as you jump into decision mode.

Let’s chew on the details:

1. Research the Reputation of Different Solar Panel Brands

Research the reputation of different solar panel brands in the market. Look for well-established companies with a proven track record of delivering high-quality products.

Quality Indicators for Solar Panels

If you're mulling over solar panels for your home, the quality standards are a big deal in figuring out their lasting effectiveness and trustworthiness.

Panel Efficiency

One of the most essential points to consider when choosing solar panels is their efficiency. Panel efficiency directly impacts their electricity generation capacity, which ultimately affects the overall energy output of the system. Higher efficiency panels can generate more electricity in limited space and under varying light conditions, making them a more attractive choice for many consumers.

Linear Output Warranty

The presence of a linear output warranty is vital for ensuring the long-term performance and reliability of solar panel kits. This type of warranty guarantees that the panels will maintain a certain level of power output over time, providing consumers with assurance regarding the expected energy production throughout the lifespan of the panels. A robust linear output warranty can offer peace of mind and financial security by safeguarding against potential declines in performance.

Comparison Across Panel Brands

When comparing cheap and premium panel brands, it's important to look at the efficiency and warranty offerings of each. While premium panels may boast higher efficiencies and longer warranties, advancements in technology have enabled some affordable panel options to provide decent efficiency levels and reasonable warranty coverage. By carefully weighing these factors against the cost differential, consumers can make informed decisions that align with their budget and performance expectations.

2 different solar panels side by side being compared

Types of Cheap Solar Panels

When it comes to choosing solar panels, there are different types available in the market. Each type has its own advantages and disadvantages. Let's take a closer look at the three main types of solar panels:

1. Monocrystalline Silicon Panels

Monocrystalline panels are known for their high efficiency, making them one of the most popular options in the market. They are made from a single crystal structure, which allows them to convert sunlight into electricity more efficiently compared to other types. These panels have a sleek black appearance and can generate more power even in low-light conditions.


  • Higher efficiency
  • Sleek black appearance
  • Better performance in low-light conditions


  • More expensive than other types

2. Polycrystalline Panels

Polycrystalline panels are another common choice for homeowners. These panels are made from multiple silicon crystals, giving them a distinctive blue color.


  • Cheaper price
  • Suitable for diverse climates


  • Lower efficiency compared to monocrystalline panels

3. Thin-Film Panels

Thin-film panels are made by depositing photovoltaic material onto a substrate such as glass or metal. They have a flexible design, allowing for easier installation on curved surfaces or irregular shapes.


  • Flexible installation options
  • Lower cost compared to crystalline silicon panels


  • Lower efficiency levels
  • Require more space for desired power output

Let's get something straight, matching your personal requirements and available financial assets to a suitable solar panel type is no small matter:

  1. If you prioritise high efficiency and can afford a higher upfront cost, monocrystalline panels may be the best choice for you.
  2. If you're on a tight budget but still want decent performance, polycrystalline panels offer a cost-effective solution.
  3. If you have unique installation requirements or limited space, thin-film panels might be the most suitable option.

When it comes down to it, your choice hinges on your personal needs and how much room you've got for installation. 

Don't forget, it's a smart move to seek advice from a reputable solar panel installer or manufacturer to figure out which type of panel fits your brief like a glove.

Government Support and Incentives for Solar Panels in the UK

Let's take a peek at the hefty handouts the UK government's dishing out to make it a smidgen easier on your purse strings, and encourage us all to embrace a bit of that delightful renewable energy.

Here's what's up:

UK government grants for homeowners

Did you know that the UK government is throwing cash your way to make going solar a smoother ride?

By offering several grants and financial incentives, they're helping reduce those hefty initial costs that come with solar panel installation.

Crack open that piggy bank and count off a hefty chunk less in solar panel costs, thanks to these bountiful grants.

It's like Christmas for energy efficiency!

Energy Company Obligation (ECO4) scheme

This clever initiative known as ECO4 does seek to support those struggling with fuel poverty and outdated insulation.

Neat, huh? 

So, who’s this scheme got its beady eye on, you ask?

Predominantly, we’re talking about folks on low incomes, living in properties that are about as energy-efficient as a sieve.

If that has a familiar ring to it, well, you might just be in with a shot at catching a break with this support scheme.

Swing by the government's 'Eligibility Checker' for all the details

So, you're ready to hop on this solar-paneled gravy train - what next?

Start by giving your energy provider a bell; they will hold your hand and guide you through the application process.

It's all very official – you might end up having to fill in forms or make earnest, phone calls.

Smart Export Guarantee (SEG) 

Now, let's have a natter about the Smart Export Guarantee (SEG). You might be thinking, "Alright, what’s this all about then?" Well, prepare to have your solar-powered socks knocked off, friends! 

Launched by the UK Government in 2020, the SEG is a scheme that makes energy suppliers with over 150,000 customers (the big guns, essentially) pay households for the surplus renewable electricity they export back to the grid.

So with SEG, essentially you'll have the power companies footing your bill. No, you're not dreaming! These big energy companies must offer an export tariff to small-scale low-carbon generators.

  • Economy Alert: While the tariff rates are not fixed, they have to be more than a big fat zero (Ofgem's playful, not-so-beneficial way of saying they can't stiff you worse than a rotten cuppa).
  • Freedom to Switch: You're not stuck with a supplier if they try playing silly buggers either. You can switch, keeping those providers on their toes!

Now, while this all sounds like rainbows and unicorns, there are a few catches.

Firstly, your system size must be less than 5MW: if you're thinking of decking out the entire neighbourhood in solar panels, you're out of luck.

And secondly, your system must be MCS-certified. This ensures that the installation meets the agreed industry standards.
