EV Home Charging Stations with Solar Panels
电动汽车或EVS对环境的危害性比汽油和柴油汽车更低，并且跑步得多，这只是越来越多的人正在制作开关的许多原因中的两个。
If you are considering getting an electric vehicle, or you already own one, you may be interested in a simple way that you can further reduce the environmental impact of running an electric vehicle, and significantly reduce the already low running costs. Namely, by installing an EV home charging station and powering it with solar PV panels.
How does an electric vehicle work?
电动车辆由一系列电池供电，坐在汽车的地板下方。控制单元管理所需的能量（每秒数千次），仪表板上的交互式触摸屏显示电池电量将覆盖的电池电量有多少，以及您使用的电量。因为汽车不需要通常发动机和传输，所以汽车内部通常有更多空间。
Pros of driving an EV
电动汽车或电动汽车正变得更通用n sight on UK roads, and a big reason for their popularity is that – unlike petrol and diesel vehicles – they do not produce harmful emissions at the tailpipe, and they are often cheaper to run than petrol and diesel vehicles. There are now lots of EVs on the market offering a variety of different features, recharge times, impressive mileage range capacities, fast charging, government benefits and incentives, and they all offer a spacious, smooth, and easy driving experience as they do not have gears.
驾驶EV的味道
然而，虽然零尾管排放是关注环境的人的明确卖点，但EVS不是一个完全绿色的运输解决方案。这是因为，虽然电力公司越来越多地使用可再生技术来产生他们的权力，但我们来自国家电网的大多数电力仍然由天然气和煤炭推动。
Another potential drawback for drivers is that there is a relatively limited number of electric vehicle charging stations in the UK. According to Zap-Map, which monitors the UK’s EV charging network, as of November 2020, there are over 20,000 EV charging devices (with more than 35,000 connectors) in over 12,500 locations across the UK. The stations are run by lots of different energy companies which charge different rates to use their charging stations, e.g. £6 for 30 minutes’ charge. An EV charging station is not like a petrol and diesel station as they are much smaller and tend to be tucked away in a corner of a car park or motorway service station.
A simple way to get past this potential problem is to install your own EV home charging station.
Using an EV home charging station
Many EV drivers are choosing to install their own home charging point, so they do not need to worry about locating a station while they are out (with the exception of long journeys), or being caught out by expensive electricity charges because they have no alternative station nearby.
EV home charging points are installed where you usually park your car. They are compact weatherproof units which are mounted to a wall. The car is plugged into the charge point and charged using electricity from the National Grid. This means that your EV running costs are dependent on your home electricity tariff.
How long does it take to charge an EV at home?
EV将充电的速度取决于汽车的制造和模型，但它以千瓦（kW）测量。EV家庭充电点将以3.7 kW或7 kW收取EV。3千瓦家庭费用单位将在12-13小时内提供全额费用，而7千瓦单位将在6-8小时内全额充电。电动车辆将在一次电荷上覆盖的里程范围取决于您拥有的电动车的模型。
How much does it cost to run an EV?
The average price of electricity in the UK is 14p per kWh or 8p on Economy 7 (overnight). An electric car will cover around 3.5 miles per kWh (on average), which works out to an approximate cost of £4 for every 100 miles or 4p per mile.
The cost of driving an EV works out to around 2-5p per mile. When you compare this to the cost per mile of driving a petrol or diesel car, the potential savings are clear.
| Average running costs | 汽油 | Diesel | Electric |
| Cost per mile | 16p | 13p | 4p |
| Cost per 50 miles | £8.00 | £6.50 | 2.00英镑 |
| Cost per 100 miles | £16.00 | £13.00 | 4.00英镑 |
| Cost per 1,000 miles | £160.00 | £130.00 | £40.00 |
| Cost per 10,000 miles | £1,600.00 | £1,300.00 | 400.00英镑 |
电动车可以比汽油轿车更便宜三倍，但有一种方法可以进一步减少EV运行成本和排放量。
EV home charging with solar panels
Solar panels are the perfect partner for an EV home charging station, as buying solar panels is like bulk-buying fuel for your EV. If you are planning on installing an EV home charging station, you should also give serious thought to installing solar PV panels on your roof at the same time. There are two big reasons for this.
Reduced emissions
If you install an EV home charging station to charge your car and power it with electricity from the National Grid, EVs are not as environmentally friendly. Unfortunately, most of the electricity we receive from the Grid is produced through the burning of fossil fuels like coal and gas which emit harmful emissions. This reduces the environmental benefits of driving an electric vehicle.
Solar PV panels convert natural energy from the sun electricity which can be used to power an EV home charging point. This means that the car will use clean energy to run and will not produce tailpipe emissions.
更便宜 - 或零运行成本
Solar PV panels generate free electricity which can charge an EV during the day. When the sun is shining on the panels, the electricity has to be used immediately or sent to the National Grid. On particularly cloudy days and during the night, solar panels do not produce electricity.
但是，通过将太阳能电池安装为系统的一部分，您可以存储在白天生成（而不是使用）的太阳能电力，以便可以在另一个时间使用，例如，它可以在另一个时间中使用。一夜之间充电。因此，如果您的EV家用充电站由太阳能供电，您有一个太阳能电池储存您的免费电力，您可以免费运行您的汽车。
太阳能电池板可以产生足够的电力来为EV充电吗？
The short answer is yes, the average sized solar panel system can produce enough electricity to not only power an EV, but also to power the average home as well. Of course, this is all dependent on the capacity of your solar panels, how much sunlight they are exposed to, how much electricity you use at home, the amount of charge your EV needs, and how many miles you cover.
For example…
平均5千瓦太阳能光伏系统可以在3月至10月之间每天产生18千瓦时。英国平均房屋（使用电磁炉）每天使用9千瓦时。
This leaves 9 kWh of electricity for an electric vehicle per day.
平均EV可以为每1千瓦时覆盖4英里。4（英里）x 9（kWh）=每天驾驶范围36英里，或每年13,000英里。
英国的冬天可能是混浊的，这将减少你的面板可以产生多少电力，但平均水平每天仍然可以生产大约7.5千瓦时，这足以为每天30英里的车供车。
To calculate the right size solar panel system for your home, you need to work out:
1. A = Average daily electricity consumption
B = Average daily mileage divided by 4 (to get the kW used driving per day)
2. Add A to B to find out C (anticipated daily kWh electricity requirement)
3. C x 365天年= D.
4. D / 1000 = suggested kWh size of pv system needed to completely offset electric vehicle and domestic electricity requirement
EV with solar panels: savings, and earnings
How much could you save on fuel by switching to an EV powered entirely by solar panels?
A 5 kW solar panel system generating 18 kWh of electricity per day could cover 9 kWh of electricity consumption in the home with 9 kWh left for an EV to cover up to 13,000 miles per year. The table below illustrates some potential fuel savings based on these figures.
| Average cost per mile | Potential savings based on 8,000 miles per year | Potential savings based on 10,000 miles per year | 基于每年12,000英里的潜在储蓄 | |
| 汽油car | 16p | £1,280.00 | £1,600.00 | £1,920.00 |
| 柴油汽车 | 13p | 1,040.00英镑 | £1,300.00 | £1,560.00 |
| EV（由国家网格提供技术） | 4p | £320.00 | 400.00英镑 | 480.00英镑 |
How much could you save on domestic electricity?
This would still leave 9 kWh of free electricity per day to cover domestic appliances. Over a year, this totals 3,285 kWh (9 kWh x 365 days) of electricity. With the average unit of electricity costing 14p per kWh, this is an additional potential saving of £460 per year.
因此，如果您正在使用家用充电点从汽油从汽油切换到电动车辆并安装5千瓦太阳能电池板系统（用电池），您的燃料和国内票据的总节能最高可达2,380英镑（£1,920 +£460）。
EV家庭充电站多少钱？
To install an EV home charging station, you will be looking at costs of £250-£800 depending on its charge capacity and the brand you choose. However, you can reduce these costs by as much as £350 with the Government-funded Electric Vehicle Homecharge Scheme (EVHS) which provides grants for home charge points. To be eligible to apply for the scheme, EV owners must provide evidence of keeper-ship, lease, be named as the primary user of an eligible electric vehicle (bought new or second hand), and have off-street parking facilities suitable for charge point installation.
Choosing an EV home charging station
选择用于使用太阳能光伏电视板的EV家用充电站时，重要的是选择与太阳能电池板兼容的型号，因为太阳能电池板以较低的速度充电。电动车具有1型或2型连接器，因此您需要确保选择兼容的EV充电点。
Electric car charging points must be installed by a certified professional which will involve mounting the chargepoint on an exterior wall or garage, near to where the car is parked. Installation takes around 2-3 hours to complete, depending on the complexity of the installation.
太阳能电池板的价格是多少？
The average home needs a 3 or 4 kW solar panel system to meet their domestic energy needs. These systems tend to cost between £3,000-£5,000. For homes looking to cover both their domestic needs and run an EV, a 5-7kW system may be necessary which typically cost £7,000-£10,000.
