The 7 Most Powerful Solar Panels in 2023

✔ Our researchers have searched extensively for the most powerful solar panels

✔ These panels all have a peak power output of 580 watts or higher

✔ The most powerful solar panel is the Seraphim SRP-670-BMC-BG

As solar panel costs have fallen in recent years, these sources of free, renewable energy have become increasingly powerful.

There are now dozens of solar panels that provide more than 500 watts (W) at their peak, and the level at the very top is only getting better with each passing year of development.

That’s great news for solar panel owners, who can now generate even more electricity – and cut their bills even more drastically – with the same amount of sunlight.

1. Seraphim SRP-670-BMC-BG

Seraphim has broken the mould to deliver an unprecedented amount of solar energy to homes.

This is an appropriately angelic solar panel – by which we mean it’s incredibly powerful and you’ll be extremely grateful to have it on your side.

670 W of peak power is almost double the 350 W standard for household panels, and it’s delivered at an efficiency rate of 21.57%, which is well above the 20% industry average.

However, to produce this much energy, Seraphim has created a panel that’s larger and heavier than any other top-tier model on the domestic market.

Its 3.1 square metres make it 55% bigger than the average panel, and its 38.5 kg see it come in at double the standard weight.

Fortunately, the great majority of roofs in the UK will be able to handle the load with no issue, so if you have the space, this model is still one of the best solar panels around.

2. Seraphim SRP-670-BMC-HV

With the top two most powerful solar panels, Seraphim is leading the way at the moment.

The Chinese solar manufacturer released this panel to provide an alternative to customers who might be put off by the weight or price of the all-conquering SRP-670-BMC-BG.

The SRP-670-BMC-HV has the same appearance as its sibling – black with a silver backsheet, frame, and gridlines – but is 4.5 kg lighter.

However, it also degrades more quickly, as shown by its performance warranty.

While the SRP-670-BMC-BG comes with a guarantee that it’ll produce 84.95% of its original power output after 30 years, this model’s warranty states it’ll generate less than that – 84.8% – after just 25 years.

They’re both excellent panels, but if you’re able to get the SRP-670-BMC-BG, we recommend doing so.

3. AIKO N-Type ABC White Hole Series (72 Cells)

It’s not top of the pile, but 620 W is a tremendous amount of power – and AIKO’s premier panel comes with some other high-quality features.

Its 24% efficiency rating makes it one of the most efficient solar panels around, and it produces its lofty level of solar power for longer than most of its rivals.

This model will generate a guaranteed 88.85% of its peak power after 30 years, which is significantly higher than the standard 86%.

Panels in this series also have a relatively resistance to heat. They lose just 0.29% of their output for every degree they heat up beyond 25°C, compared to the industry average of 0.34%.

4. AIKO N-Type ABC Black Hole Series (72 Cells)

There’s not much to choose between AIKO’s best two solar panels.

This model’s peak power output is 5 W lower, at 615 W, and 0.2% less efficient – both of which are tiny differences in the grand scheme of a solar panel system’s lengthy lifespan.

The main way the Black Hole Series version stands apart from its sibling is – logically – its all-black appearance, which gives it a sleek, subtle look.

If you want a solar panel with a peak power output over 600 W, but don’t want to buy one of the heaviest, biggest products on the market, either of AIKO’s models are fantastic options.

5. Jinko Solar Tiger Neo N-type 72HL4-(V)

The Tiger Neo is the lightest solar panel on this list, despite its enormous 585 W peak output.

It can’t compete with AIKO in terms of efficiency ratings, but 22.65% is still well above the industry average.

However, Jinko Solar – which produces its panels in China, Malaysia, Vietnam, and the US – will only supply you with a measly 12-year product warranty, which isn’t encouraging.

Our research also turned up precisely zero eco-friendly credentials – but as long as the panel holds itself together, its performance warranty guarantees a fairly good 87.4% after 30 years.

6. LONGi Hi-MO 7

The Hi-MO 7’s bifacial design allows it to absorb sunlight on both sides, to generate more electricity for your home.

The panel, which is also known by its catchy alter ego LR5-72HGD-580M, produces a massive 580 W at its peak, and has an impressive 22.5% efficiency.

It’s also more heat-resistant than most of its fellow big hitters, losing just 0.28% of its output with every degree over 25°C, and it’s guaranteed to produce 88.18% of its initial output after 30 years, which is good.

The 12-year product warranty it comes with is poor though, as is LONGi’s lack of commitment to green causes outside of solar manufacturing.

7. JA Solar JAM72D40

In the JAM72D40, JA Solar has produced a panel that’s almost exactly the same as the LONGi Hi-MO 7.

It’s almost identical, with the same size, weight, peak power output, aesthetic design, and product warranty as LONGi’s model.

However, it’s a little bit worse in a couple of ways. JA Solar’s panel has a slightly worse heat resistance of -0.30% for every degree over 25°C, and its performance warranty promises an inferior 87.4% after 30 years.

The good news is that they’re both top-tier solar panels that’ll generate enormous amounts of energy and slash your electricity bills. If you can get either of them, it’s more than worth it.

How did we choose the most powerful solar panels?

Our four researchers analysed the 48 best solar panels on the market to find the most powerful models.

We spent 34 hours trawling through panel datasheets from 17 top-tier companies to uncover the ones with the highest peak power outputs.

And we’ll return to this research at regular intervals to ensure we’re always presenting you with the best of the best.

Why is it important that solar panels are powerful?

If solar panels are powerful, they’ll generate more solar electricity, assuming everything else is equal.

Peak power output isn’t the be all and end all – you should make sure your panel has a long product warranty, high efficiency rating, and good heat resistance, for instance – but it’s one of the biggest considerations.

After all, you can’t work out how many solar panels you need until you decide which model to buy – and the more powerful the panel, the fewer you’ll need to buy.
