  • LG.offer the longest product warranty at 25 years. This is only equalled by Panasonic with most other manufacturers offering a maximum of 10 years.
  • LG.have one of the most powerful panels on the market at 395W. This is only bettered by a Canadian Solar panel which is lower in efficiency.
  • LG还在21.4%生产最有效的标准(单缩版)面板;最接近的竞争对手剧本为20%。LG双相面板也是我们比较中最有效的。
  • LG.include a 25 year power warranty with their panels. While the other manufacturers also offer a 25-30 year power warranty, LG guarantee the highest performance throughout this period. They state that their panel will be generating at 86 – 88.4% of its maximum capacity in its 25th year while the others average between 82-84%.

We think this makes LG solar panels a winner in terms of efficiency, reliability and power capacity, but the other manufacturers we compared also offer a huge range of benefits and features (at a possibly lower cost) which could make them a great choice for your home.

NeON 2 Black 325 W Mono 325. 19% 25 years 25 years 1,686 x 1,016 x 40 18

NeON R

The NeON R 370W is LG’s efficient solar panel at 21.4%; this is the highest efficiency level achieved by any of the panels we found. In addition, LG guarantee that NeON R panels will still be working at 88.4% of their original capacity in the 25th year.

NeON 2

This is LG’s most popular module delivering a high efficiency of 19.8%. It includes CELLO technology replacing 3 busbars with 12 thin wires to enhance both power output and reliability.

NeON 2 Black

霓虹2黑色有较薄的电线,距离距离显示所有黑色,以增强安装的美学,并可能在其现代设计中增加价值。

LG.also offer the NeON 2 Bifacial which has cells on both the front and back to maximise energy generation by up to 30%; this has a power capacity of 395W. We’ve compared bifacial panels separately from the standard monofacial a little later in the article but (spoiler alert) LG come out on top in that comparison too.

松下solar panels

松下太阳能板

松下is a big name in the technology industry but you may not be aware that the company’s expertise also extends to solar energy. Originally under the SANYO brand, the company has been developing photovoltaic technology since 1975. Panasonic Solar panels are the result of over 40 years of research and innovation and this is evident in the quality and reliability of their solar panels. They also offer an impressive 25 year warranty for both product and power.

There are 4 solar panels in Panasonic’s HIT range, all made with monocrystalline silicon for maximum efficiency:

面板 类型 最大功率(瓦特) 最大的英孚ficiency Linear Power Output Warranty Product Warranty 尺寸(mm) 体重(公斤)
HIT N325K KURO – Black Mono 325. 19.4% 25 years 25 years 1590 x 1053 x 40 19

HIT N295 Compact Mono 295 19.1% 25 years 25 years 1463 x 1053 x 35 18

击中Kuro Black 325W

The Kuro is a 96 cell module designed with both aesthetics and durability in mind. Completely black, it is finished with a thick 40mm frame and can withstand a wind and snow load of 5400 Pa. The panel features Panasonic’s unique water drainage corners to promote self-cleaning of the module and minimise dust accumulation for easier maintenance and a better long-term performance. The anti-reflection glass increases the energy absorption, minimises efficiency losses and reduces the risk of cells micro cracks due to lower laminate thickness.

HIT Powerful 330W

This is Panasonic’s most energy efficient module at 19.7% and is also the most powerful module in the range at 330W. It reaches this power level with just 1.67m² of surface which is around 25% more power than other comparable panels. It is finished with an anodyzed black frame to give a monochrome appearance and corner water drainage to keep the panels cleaner all year long.

HIT Slim 245W

松下命中纤薄的设计专为小屋而设计,希望通过更少的空间最大限度地发挥能量产生。在160厘米的长度不到160厘米,宽度小于80厘米,它可以适应许多安装,其设计允许混合肖像和景观安装。它完成了一个带有水角排水的混合黑色框架。

HIT Compact 295W

Although named for its compact size at less than 150cm long, this module delivers a relatively high power of 295W. This small size allows more rows of panels on a roof to increase the output. It is finished with an anodyzed black frame with water corner drainage.

sharp solar panels

Sharp Solar Panels

The Japanese electronics corporation,Sharp, has been in existence for over 100 years with their solar research and development beginning in 1959.

How to choose the best solar panels

类型s of solar panel

There are 2 main types of solar photovoltaic (PV) panel to choose from: monocrystalline or polycrystalline. This refers to the type of silicone in the panels and impacts how effectively they will produce energy for your home.

一般来说,单晶面板更有效,持续更长,在设计中看起来很畅销。然而,正如您所预期的那样,这些益处具有比其多晶对应物更高的价格标签。大多数专业人士将建议您选择单晶,但如果您愿意将成本降至最低,则多晶可能仍然是有效的选择。现在也可以购买双面和背面的PV电池的双层太阳能电池板,以最大化您的能量产生。

In terms of aesthetics, monocrystalline panels tend to be black in colour (which many homeowners find a more attractive option) and polycrystalline are blue. You can opt for photovoltaic panels which are attached to frames and sit slightly above the roof, while others can be integrated with your tiles so they blend in more seamlessly.

Efficiency

The efficiency of your solar panels is one of the biggest factors to consider. The higher a panel’s efficiency, the more energy it will generate for your home.

When comparing efficiency remember to look at ‘module efficiency’ rather than ‘cell efficiency’. The efficiency of the individual cell will be a higher number but doesn’t represent the overall capacity of the solar panel. Modern solar panel efficiency usually sits between 16 – 20%. A solar panel with an efficiency of 19% or more is what you should be looking for, but they are more expensive.

However, you should also consider the size of your roof. If you don’t have very much roof space then you’ll need to buy a small number of the most energy efficient panels you can afford. But if you have a large roof, you can install more panels of a lower efficiency which may enable you to reduce your upfront costs.

Warranty

与任何保修一样,制造商愿意保证其产品的较长者,您应该具有其质量的越来越信心。在太阳能电池板的情况下,它们具有2种类型的保修期:

  • Product Warranty: This guarantees the workmanship and manufacturer’s components. If your solar panel breaks during the product warranty period they should repair or replace it at no charge. These range from 10 – 25 years.
  • 电力保修:这是指太阳能电池板将继续产生能量的时间长度以及它将有效地实现。例如,大多数制造商都将保证您的面板将至少90%的能力发电10年,80%,持续25至30倍。

Power Output

The higher the power output of your solar panels the more electricity it will supply your home with. The power output is measured in watts (W) and generally domestic solar panels range from 200 – 400W.

Solar panels with an output of 300W are the best choice if you want to generate all (if not most) of your electricity with them, but these will be more costly to purchase. Solar panels of 200 – 275W will be less expensive and while they will only generate some of your home’s electricity, they can still significantly reduce your energy bills and carbon footprint.

Reviews

您通常可以通过在线论坛和消费者审查网站浏览来良好的概述品牌的声誉。

Don’t underestimate the value of good old fashioned word of mouth. As solar panels have become more affordable they are becoming a more popular choice among homeowners, so the chances are you’ll have family or friends who have their own. Which brand did they choose? Were there any problems during installation or since? Have they noticed a significant drop in their energy bills?

Once you’ve identified a few brands you’re interested in, the next step is to contact some approved installers in your area. They’ll be able to assess your home, lifestyle, energy requirements and give you a bespoke quote.Get quotes for solar panels now.

成本

On average, a solar panel system costs around £6,000 – £7,000 including the installation, but you can find systems for as low as £3,000. The cost will be impacted by the brand, type, power output and efficiency of the panels, plus the labour costs of the installation.

However, when you are considering the upfront cost of a solar panel system it’s important to factor in the long term financial benefits. Generating your own electricity will mean a significant drop in your energy bills.

为了获得太阳能电池板的确切成本,您需要获得多项报价。MCS认证(或等效)太阳能安装人员将为您提供免费的,无义务的报价,这些报价告诉您他们为您的家提供了哪些系统以及他们将收取多少系统。您应该始终从至少2或3家不同公司获取引号,以比较他们的建议并确定您获得最佳交易的地方。

双齿轮太阳能电池板

什么是双相太阳能电池板?

Bifacial solar panels have PV cells on both the front and back; when the panel is installed on a reflective surface this maximises the amount of energy it can generate. Manufacturers claim that bifacial panels are capable of producing up to 30% more energy. It is possible to buy polycrystalline bifacial panels but most are monocrystalline.

Best Bifacial Solar Panels (Most Efficient)

Here are the UK manufacturers currently offering bifacial solar panels as well as the most efficient model in their range:

4 reasons to install solar panels

1.你会在电费上省钱

Generating energy for free with your own solar panels means you’ll need to buy less energy from your supplier and you should quickly see a reduction in your bills.

2. You’ll reducb your carbon footprint by using renewable energy

与标准电力不同,太阳能电力的生产不需要燃烧化石燃料,太阳能电池板不会向大气中发出碳。

3.即使在阴天的日子里,你会全年产生能量!

While solar panels are obviously more effective during the summer when there are more hours of sunlight, solar panels will also be generating energy on cloudy days so can contribute to your home’s energy supply all year.

4. You can lessen your reliance on the National Grid

Generating energy from solar panels takes you several steps closer to independence as you need to buy less and less electricity from your supplier. If you also install a solar battery storage system, you can keep hold of solar electricity you’ve not used during the day for use at night which is yet again another step closer to energy freedom and increase the money saved on energy bills.

Solar battery storage

当你安装太阳能板电池存储器中ge system you can increase the amount you’ll save on your electricity bills even further. Your solar panels will be generating energy during the day but any energy not used will be sent to the National Grid automatically. This means that at times when your solar panels aren’t generating energy, e.g. at night or on particularly cloudy winter days, you’ll need to buy energy from a supplier.

但是,如果您在白天安装太阳能电池存储以保持您未使用的能量,则可以在需要时访问更多您的自由能。看看我们的比较bob app下载

How to get a great deal on the best solar panels

When choosing solar panels for your home, you need to ensure that the panels are approved by the Microgeneration Certification Scheme (MCS). The MCS is a nationally recognised quality assurance scheme for technologies which produce electricity and heat from renewable sources. If your panels or your installer aren’t approved by MCS or an equivalent scheme, you are at risk of getting low quality panels.

And, as we’ve said a few times now, to get the best price on your solar panels you need to compare at least 2 or 3 different quotes. At Solar Guide we have a network of MCS certified (or equivalent) solar installers all over the UK. Send us an enquiry today and we’ll put you in touch with up to 3 companies in your area. They’ll provide you with a competitive, free and no-obligation quote bespoke to your home.
