Allow me to introduce you to a genuine game-changer for the world of solar panels – the unforgettable Perlight NTA 430W, a product of the reliable Westech Solar UK Ltd.

Let's dive right in and explore the reasons that put it ahead of the pack. 

Quick takeaway: 

  • Perlight NTA 430W utilises n-type cells, known for their resistance to Light Induced Degradation (LID). In other words, they churn out more power.
  • Tested and certified to withstand wind loads up to 2400 Pa and snow loads up to 5400 Pa. That's resilience, people!
  • Exemplary PID (Potential-induced degradation) resistance, thanks to optimised production processes and careful materials usage.
  • High efficiency rates (more on that later) mean more power generation from the same amount of sunlight. Clever, right?

Pros and Cons of Perlight N Type

Pros
  • Due to goof-proof n-type cells, Perlight NTA 430W is a power-generating machine, even in low light conditions.
  • Built tough to withstand challenging environments: think coastal cliffs and harsh deserts.
  • Certified against extreme weather conditions, with impressive wind and snow resistance. No fair-weather friend, this one!
  • Excellent PID resistance ensures longevity and stability. Useful, since I hear the sun isn’t going away anytime soon.
Cons
  • May present a higher initial investment compared to some other panels.

Researching UK Solar Panel Suppliers

Strap in, as we talk you through a few vital points to mull over.

Price Tag 
  • Time to play detective and ferret out what the different suppliers are charging for their glossy solar panels. Let's not forget, being thrifty is a virtue, but never at the cost of scrimping on quality!

  • Don't get tunnel vision focussing on the price tag alone. Give a thought to what goodies are tossed into the package - could it be worth taking a punt and shelling out a few more quid for a truly radiant deal?

Quality of the Panels
  • Investigate if your potential supplier is a purveyor of solar panels known for their longevity and performance.
  • Put your nerdy hat on and delve deep into the kind of tech and materials they're stuffing into their panels. 
Warranty
  • Uncover the truths of their warranty – what's covered, how long it's valid.
  • Look into the ifs and buts of the warranty, because no one likes nasty surprises, do they?
Customer Reviews
  • Do a bit of treasure-diving on customer reviews or feedback. It's a bit like being a detective, but in a couch-potato kind of way.

  • Eagle-eye any recurring pains or grumbles - because where there's smoke, there's often a fire, or in this case, an unsatisfactory solar panel.

Expert Opionions
  • Seek the cadvice of solar energy gurus. Like, legit people who know their photovoltaics from their thermodynamics.
  • Look for advice from independent organisations.

What to Consider When Choosing Solar Panels?

You'll need to be armed with a few facts before you step onto that green stage. Here are four of your solar 'must-consider' factors: 

1. Cost

First and foremost, you have to look at the big bucks you'll shell out initially for your new solar panels. No beating around the bush, the best solar panels can be a bit pricey at first bite. However, the perks they bring along (like lower energy bills and durability) can sweeten the deal down the line. (Let's call it delayed gratification, shall we?) As per a study by the Independent, the average cost of installing solar panels is about £6,000-£7,000, depending on the size of the system you go for[1]

2. Payback Timeframes 

Next up on our solar checklist is the payback period. That's the time it takes for your energy bill savings to foot the bill of those shelled-out solar pounds. A shorter payback period? That's a hot investment! With UK homeowners switching on to an energy-saving mindset, the average solar panel kit payback period is around 10 years, but with the right system, it could be as low as 8 years.[2] 

3. Power Output

Of course, you can't overlook the energy-oomph different solar panels can churn out, can you now? Solar panels packing a power punch can generate more electricity and potentially save you a fair few quid. In our good ol' UK, a 4kWp system would generate 3,400 kWh per year - that's enough juice to run a typical household.[3] 

4. Efficiency 

Lastly, let's chat about efficiency - just how well your shiny new solar panels can turn sunlight into electricity. Panels with a hefty efficiency rate are just the ticket when you're working with nip and tuck spaces or less than stellar sunlight situations. According to research, the most efficient solar panel available in the UK can convert sunlight at a rate of up to 22% [4].

illustration of how solar panels work on a UK home

How The Best Solar Panels Work

Ever wondered how those snazzy little solar panels convert our beloved sun's rays into usable electricity? There's a few precise steps: 

1. Absorption

Solar panels are essentially soap operas for photons. Comprised chiefly of silicon photovoltaic cells, these panels become the stage where sunlight, or more specifically, photons in the light energy, get completely soaked up by the waiting silicon (sources: Britannica). 

2. Electrons

The drama unfolds as absorbed photons, somehow finding within them the energy equivalent of a double espresso, manage to break free from their atoms, creating electron-hole partners amidst the silicon crowd (sources: Nature). 

3. Electron Flow

The emancipated electrons, now buzzing about the panel, become an electric current. Think of it like a mini electron marathon within the structure of the solar panel. 

4. Let There Be Electricity! 

These tiny electron joggers, in their journey, traipse through an electrical circuit. And voila! they generate electricity that can be harnessed to power your device or even stored for later use (just like those leftover roast potatoes!) 

on roof cleaning solar panels to look their best

Making Sure Your Panels Look Their Best

We’ve got to talk serious aesthetics here, folks. Sure, we’re saving the planet (small pat on the back there) but remember, we’ve also got to keep the neighbours and stares from passersby in check.

So, what about the look of those sleek solar panels gracing your property? The plot thickens! 

Why aesthetic matters
  • Solar panels last a long time, so it's important to pick ones that go well with the style of your property.
  • Choose panels that are thin and don't stick out too much from your roof.
  • Some solar panels are all black and have a modern look. They still work great.
  • Talk to an solar installer expert who can tell you where the panels should go on your roof to make them look nice.
How to clean solar panels
  • It's a good idea to have a professional clean your solar panels every now and then. If they get dirty, they won't make as much energy.
  • Have them cleaned twice a year to get rid of dust, dirt, bird poop, and other stuff that gets on them.
  • Don't use anything rough or strong that could damage your solar panels.
  • Rinse with a hose that doesn't spray too hard.
  • Before you have them cleaned, check with the company that made your panels to see if they have any special instructions.
How to take care of solar panels
  • Look at the part that holds the panels in place two times a year to make sure it's still strong and doesn't have any problems.
  • Check for rust on the metal parts, especially if you live near the sea. If you find any, fix it quickly.
  • Keep an eye on how much energy your panels make, especially after you clean them. If they don't make as much as before, there might be something wrong and you should get help from an expert.

These steps are best taken care of by a solar professional and would usually be carried out as part of an annual service of your solar panels.

They can also make your property look great if you choose the right ones and keep them clean and maintained.
