太阳能电池允许您使用您的太阳能电池板产生的更多能量。将太阳能电池存储器添加到太阳能系统上将进一步降低您对能源供应商的依赖,甚至进一步储蓄。

什么是太阳能电池?

太阳能电池允许您在晚上和晚上继续为您的房屋提供可再生太阳能,当太阳能电池板不能产生能量时。太阳能光伏面板将太阳能转化为可用的电力,更频繁地,它们的产生比可以使用的电力更多。如果没有太阳能电池,那么多余的时间就会送到国家电网。这意味着你会错过自己的能量,一旦太阳落山,就必须依赖你的能源供应商。

Solar battery storage technology allows you to use more of the free energy produced by the solar panels to save money and increase independence from the National Grid.

这list of the best solar batteries is growing all of the time. With the Tesla Powerwall, Powervault and Sonnen solar batteries often coming out on top as the best solar batteries.

根据您的能源需求,您家的最佳太阳能电池可能与另一个不同的太阳能电池不同,因此重要的是比较不同的型号。当您比较太阳能电池板电池存储系统时,有几件事要留意:

Capacity:这是可以随时存储在太阳能电池内的最大能量。在英国,平均家庭每天使用约8-10千瓦时。我们列表中最好的太阳能电池的最大容量与PowerVault 3.有b0b体育平台咋样些太阳能电池是可堆叠的,这意味着随着时间的推移,您可以将更多单元添加到太阳能电池存储系统以增加容量。

技术:All of the solar batteries featured in this article are Lithium-ion based, this is the more progressive technology and the same battery technology you’ll find in your laptops, mobile phones and electric vehicles. There is still a strong and well established market for lead-acid batteries (the kind you’d find in your car) and they are still popular with many solar power users who live off grid. Lead acid batteries are tried and tested technology that dates back over 100 years and they are cheaper in terms of upfront cost. However, Lithium-ion batteries have a lower life-time cost and operate at a much higher efficiency level.

循环保证:太阳能电池循环是它可以完全充电的次数。许多太阳能电池制造商提供保证在一定数量的循环后保证一定的性能。保修的循环越多,太阳能电池仍将保持高于某个存储容量。

PowerCut备份:在PowerCut期间,并非所有的太阳能电池都将继续为b0b体育平台咋样您的房屋提供可再生太阳能。寻找将提供PowerCut备份的模型,因为它们将继续工作。

太阳能电池的好处

    • Energy bill savings:By storing energy during times of lower demand you can reduce the amount you need to buy from your energy supplier when energy usage is higher, saving you money on your energy bills.
    • Backup Power Supply:一些太阳能b0b体育平台咋样电池将使您能够在有电源切割时使用您的太阳能电力,因此您尚未留下电源或照明。当一个电源切口击中这种能量的商店可能对您的家庭非常宝贵。

并非所有的太阳能b0b体育平台咋样电池都使您在电源切割期间使用太阳能电力,因此如果这是优先级,请确保您选择具有此功能的电池。

When there is a drop in voltage on the grid, solar batteries detect this and will automatically turn off the inverter and disconnect your battery from the grid as a safety precaution; engineers will be working on electricity lines on the grid and if batteries are connected to it there is a risk of electrocution. This is called islanding and is essentially a safety barrier between your incoming supply and your fuse board.

如果备用电源很重要,您需要查看交流耦合系统。在撰写本文时,我们只能在英国找到3个电池系统,在电源切割期间将保持灯光。这Tesla PowerWall 2.0.使用备份网关。此更新版本的PowerWALL 2.0提供了一个单独的单元,看起来像电池本身的较小版本,并在断电时完全岛屿。第二个和更便宜的选择是Puredrive的预测电池系统。最后,三星SDI还可以在停机期间提供紧急权力。随着电源备用可能不适合标准,始终将制造商联系。

How much do the best solar batteries cost?

在安装前,太阳能电池价格可以从500英镑到超过10,000英镑的价格,这可能达到500英镑的价格。

如果改造,您可能还必须将逆变器的成本增加到现有的太阳能电池板,这可以增加1000英镑。值得注意的是,有很多“混合的”系统,它结合了逆变器和电池存储器。

太阳能电池如何b0b体育平台咋样工作?

太阳能电池板安装在屋顶或外墙上,可以暴露在最多的阳光下。每个面板包括太阳能电池,其将太阳能的能量转换为直流电力,然后通过逆变器转换为交流电力。然后可以用来为您的家供电。

Whatever you don’t use is sent back to the National Grid to be redistributed around the country. This means that you can only use solar energy as and when it is available, i.e. when the sun is shining. However, this is not the case if you install a solar battery…

By introducing a solar battery into the process you can keep hold of the surplus energy you’ve produced for use at another time (e.g. at night) and further reduce your reliance on the National Grid.

将太阳能电池贴在家中

可以存储自己的电力的太阳能系统有三个主要成分:

  • Solar panels that absorb and convert the sun’s energy to DC electricity.
  • A battery (or batteries) to store the electricity that is not used for use when the solar panels aren’t generating electricity.
  • An inverter that converts DC electricity to AC ready for use in your lights, appliances etc.

As solar technology continues to progress many modern systems also incorporate smart technology such as apps and Wifi so you can easily monitor the battery’s charge level and general efficiency.

Types of solar batteries

AC or DC?
您选择的太阳能电池需要是您需求的正确尺寸或电压。这是非常重要的,因为错误的尺寸可能会带来非常真实的安全风险。我们强烈建议在达到最终决定之前与多个专业安装人员进行咨询。

In addition to choosing the right voltage, you will need to consider if AC or DC is the best choice for your system. The main difference is in the way the battery connects – or doesn’t connect – to your solar panels.

AC:AC(交流电流)电池没有直接连接到太阳能电池板,但通过电表连接。这意味着改装对现有面板更容易,因此如果您已经在适当的太阳能电池板,这可能是您的最佳解决方案。您需要一个额外的逆变器将直流电力转换为AC,以便在您家中使用,然后返回DC以存储在电池中。PowerVault 3是交流耦合系统的示例,而Tesla的PowerWALL 2.0是DC耦合系统的示例。

DC:直流直接连接到面板时,直流(直流电流)电池往往是太阳能电池板的同时安装。您不需要额外的逆变器,因为它在电表之前连接。

Solar battery storage: What you should consider

持续维护
A solar battery is not a simple ‘install and leave’ unit. It needs regular monitoring and maintenance to keep it working both efficiently and safely. This includes keeping it charged at an optimum level, carrying out regular power ‘boosts’ and gassing as well as ensuring it is stored at a correct temperature and protected from the weather.

替换零件
b0b体育平台咋样太阳能电池不会持续到太阳能电池板。目前,高质量的太阳能电池将持续约10-15岁,但这取决于您使用的数量并确保其维护正确。电池可容纳2,000英镑(不包括安装),因此需要考虑的重要费用。

It’s not a complete energy solution (yet)
这ultimate ambition for many is to make complete energy self-sufficiency a reality, without any reliance on the National Grid at all. While technology is certainly moving in the right direction and has made great strides in recent years, a solar battery system is still not a viable option to completely disconnect from the mains supply. Batteries have their faults, shelf-lives and limitations, so until things have progressed it’s necessary to have the option of a backup supply from the National Grid.

您需要太阳能电池板是否有太阳能电池?

不。If you live in an area affected by regular power cuts then a home battery could be just the system you need to keep the lights on. On average you’ll probably get around 24 hours of backup power but this can be increased by simply installing more batteries. If you’re on an Economy 7 rate a home battery can also save you money by charging when electricity is at it’s cheapest for you to use when it’s not so cheap. Finally, you can even make money by storing energy for the National Grid who can discharge it from you in times of need.

您可以将太阳能电池添加到现有的太阳能电池板吗?

Yes and no. Some batteries will only work when installing a new system or one that was specifically designed for it (特斯拉PowerWall 2.)一些系统会对任何系统改造。

Are solar batteries safe?

这y are as safe as as any other electrical item in your home. Generally installing a solar battery is not a DIY job and for the most part the public can’t buy solar batteries direct from the manufacturer but rather via an approved installer.

太阳能电池容量是什么意思?

This is the ‘usable’ amount of energy in kWh (units) that the battery will store. It’s never a good idea to run a battery down to empty as it will cause damage, so when you are comparing capacities remember to check if the figure given is ‘total’ or ‘usable’.

How do I know which power output will suit my property?

这power output of a solar battery is, quite simply, how much power the battery can deliver at one time. The more electrical appliances and lights etc. that you plan to power with the battery, the higher this will need to be.

What happened to the Feed-in Tariff?

这Feed-in Tariff (FiT) scheme has now closed. Back in 2010, the government introduced the Feed-in Tariff scheme which paid owners of eligible PV systems for every kWh of energy they generated and each kWh of unused energy which was exported to the National Grid. Although this scheme was a great incentive for homeowners to install solar panels, it also prevented some homeowners from installing a solar battery as they feared they would receive lower payments if they did not send their surplus energy to the grid.

这FiT scheme closed to new applications in March 2019, so if you are yet to install solar PV you won’t be paid for sending your surplus energy to the National Grid and will save much more money by keeping hold of it.
