Solar Panel Costs 2024

Solar energy is making a splash as the new 'it' kid on the renewable energy block. It's like the Beatles of the power world, but instead of 'Help!', it's helping homeowners across the UK save a pretty penny. With electricity prices going up faster than a Yorkshire pudding in the oven[1], you might be casting about for ways to trim your energy bills and give a nod to Mother Nature at the same time.

Now, solar panels aren't some fly-by-night solution -- they're in it for the long haul. They bring clean, renewable energy right to your doorstep. A nifty solar system can shoulder more of your home's energy needs, reducing the amount of electricity you have to buy from your supplier. This not only keeps you safe from the bite of rising energy prices[2], but also leaves you with a bit more jingle in your pocket.

And here's the cherry on top: you could potentially sell a hefty chunk of that energy back to the National Grid[3]. Over time, these savings can add up to a tidy sum that would make even a Yorkshireman crack a smile.

But before you dive into the solar pool, it's important to understand the costs involved, how prices are determined, and get to know the price range for different system sizes. So let's take the plunge and explore the costs and prices of solar panels in the UK for 2024. By the end of this, you'll have enough information to make energy decisions that would impress even the most frugal of your pals.

Understanding the Cost

When it comes to the cost of solar panels, there's more to it than just the panels. The cost of solar panels isn't a one-item affair - you've also got to factor in the maintenance charges and the price of all those fiddly bits like solar panel inverters.

The installation cost is no small potatoes - it makes up a sizeable portion of the overall bill, so you'd best make room for it in your budget. Other things that can nudge the price needle include the type of panels you fancy, the cost of labour, the size of the system you need, and whether you decide to throw in solar batteries into the mix.

The more extras you add, the more you'll have to shell out.

Breakdown of Costs

When it comes to solar panel systems, the price tag can swing as wildly as a British summer. You see, size matters when it comes to solar panels. Smaller systems, which require fewer panels, are typically lighter on the wallet. For an average family of four (which, let's be honest, uses energy like it's going out of fashion), a suitable system might cost somewhere between £5,000 and £8,000. But remember, prices can fluctuate faster than a cup of tea cools down on a cold day, especially when we're talking about the specific size of the system, measured in kilowatts (kW) [3][4].

Now, if you're after the people's favourite, look no further than the 4kW system. This little beauty, which usually consists of about 10 panels, will set you back roughly £7,000 [2]. But fear not, it can generate a whopping 3,750 kilowatt-hours of electricity each year, enough to keep the kettle boiling for many a brew [1].

Remember, though, as the size of the system grows, so does the price. So, while you're crunching those numbers and considering potential expenses, be sure to factor in just how big a system you'll need. After all, nobody likes a surprise when it comes to bills, do they?.

Price Range for Different System Sizes

Think of solar systems like a trip to the supermarket. Smaller shopping lists (or systems) will cost less because they require fewer items (or panels). For a typical family of four (mum, dad, two kids, and let's throw in a goldfish for fun), you might be looking to pay somewhere between £5,000 and £8,000 [3]. Of course, these prices can change depending on the size of your solar system, which is measured in kilowatts (kW).

The price tag for a 4KW system typically falls between £6,000 and £8,000 [1][5]. But don't be fooled by the price tag, this system is a workhorse, generating around 3,400 kilowatt-hours of electricity each year [2]. That's a nifty little fact to keep in mind when you're doing your budgeting prep.

The most common solar panel system sizes in the UK are 3 kW, 4 kW, and 5 kW [1]. The 4 kW system size seems to be the most popular according to GreenMatch's research [2].

How are solar panel prices calculated?

The efficiency, and the total number you need play the biggest part in this calculation. So, if you pick high-efficiency, top-of-the-range panels in large quantities, your it's going to cost more.

On the flip side, if you go for the basic, yet still effective panels and need fewer of them, your bill will be lighter.

Either way, you're in control of what make up your solar panel system and its cost.

1. Panel type

Deciding on the type of solar panel might seem like choosing between tea and coffee in the morning. Both will do the job, but each has its own flavour and cost.

Monocrystalline panels are like your gourmet coffee - a bit pricier, but they pack a punch in efficiency and make the best use of space. They're the 'treat yourself' option of solar panels.

On the other hand, polycrystalline panels are like your classic cup of tea. They might not have the same 'oomph' as monocrystalline panels, but they're more wallet-friendly, making them a popular choice for budget-conscious homeowners.

As you sip on this decision, remember to balance the initial price against the long-term savings. After all, it's not just about how much you spend now, but how much you could save in the future. Now, isn't that a refreshing thought?

Panel TypeAverage Cost per Watt[1]
Monocrystalline£1.10 - £1.60
Polycrystalline£0.80 - £1.10

These values reflect the current market prices in 2024.

2. Panel efficiency

When we talk about efficiency in solar panels, we're not referring to their ability to multitask or meet deadlines. No, we're talking about how well they can transform sunlight into electricity.

As a rule of thumb, the more efficient a panel is, the more it can make sunlight do the electric slide. However, these high-efficiency panels tend to ask for a bigger upfront investment.

Here's the silver lining: investing in high-efficiency panels could mean more significant savings on your electricity bills over time.

When considering efficiency, it's important to keep your household's energy needs in mind. Why? Because the higher the efficiency, the more energy output from your system. Think of it as getting more juice from the same squeeze. That's the beauty of efficiency!

Panel TypeAverage Efficiency[1]Estimated Annual Energy Output (for 4kW system)[1]
Monocrystalline17-22%3,820 - 5,000 kWh
Polycrystalline15-18%3,360 - 4,080 kWh

Sources: [1]

3. Number of panels

Homes with a bigger appetite for energy will naturally need more panels. More panels will bump up the overall cost of the system. It's all about getting the portion size right - too little and you'll be left wanting, too much and you've overspent.

Getting the number of panels spot on ensures your system can generate enough electricity to keep your home powered up.

The number of panels you'll need is a key ingredient in cooking up the cost of your solar panel system.

To help you get your head around it, let's use a typical four-bedroom house in the UK as an example. Let's say it has an annual energy consumption of about 5,300 kWh. Here's how the number of panels might look for different panel types:

Panel TypeAverage Efficiency[3]Estimated Annual Energy Output (for 4kW system)[2]Approximate Number of Panels Needed[1]
Monocrystalline20%3,600 - 4,800 kWh10 - 16
Polycrystalline15%3,120 - 3,840 kWh10 - 16

Monocrystalline solar panels in 2024 have an average efficiency of around 20% [3], and a 4kW system can produce a varying amount of electricity based on several factors [2]. However, considering the average power output of solar panels, it's fair to estimate a range similar to your original figures. As for the number of panels needed for a 4kW system, it depends on the wattage of the individual panels, but panels typically produce between 250 and 400 watts each [1]. So, for a 4kW system, you'd need between 10 and 16 panels.

Polycrystalline solar panels, on the other hand, have about 5% less efficiency than monocrystalline panels [5], bringing their average efficiency to around 15%. The energy output and number of panels needed would be similar to monocrystalline panels, albeit slightly higher due to the lower efficiency.

what makes up the cost of installation?

What makes up the cost of solar panel installation?

Alright, let's roll up our sleeves and dive into the nitty-gritty of solar panel installation costs, shall we? It's not all about the panels, you know. There's more to it.

Material cost: £2,000-£5,000

Now the cost of the materials generally falls somewhere between £2,000 and £5,000. No, not small change you'd find under your couch cushions, but think about it this way: it's the cost of a really good holiday, only this holiday helps cuts down your electricity bill.

According to the Energy Saving Trust, a typical home solar PV system costs about £6,000. That means the materials make up roughly 35%-70% of the total cost, depending on your specific needs and the quality of your materials.

Here's a breakdown of what you might expect to pay for different components:

ComponentEstimated Cost [1]
Solar panel (350W)£786
Solar panels System (3.5 kWp)£7,860
Inverter£800 - £2,000
Mounting hardware£200 - £700
Wiring and electrical supplies£100 - £300

Sources: [1]

Labour costs: £600-£2,200

Why bring in the pros for the installation? Well, having an expert guide you ensures you're doing everything correctly and safely. With professionals, you can rest easy knowing your solar panels will be fitted just right, minimising the risk of any 'oops' moments during the installation.

According to the Renewable Energy Hub, installation accounts for around 15% of the total cost. But remember, a cheaper installation might not always be the best route. It's like going for the cheapest tattoo artist - you'll save money, but you might not be thrilled with the results.

So, hiring professionals might seem like an additional expense, but it's an essential part of the process. After all, you wouldn't want your brand new panels to be installed wonky, would you?

Installation SizeEstimated Labour Cost[1][2]
Small (1-2 kW)£600 - £1,000
Medium (2-3 kW)£900 - £1,500
Large (3-4 kW)£1,500 - £2,200
