Solar PV: Pros & Cons of Solar Photovoltaic Systems

房子的太阳光伏面板

The sun radiates enough energy in a single hour to power the whole planet for a year, but we are not yet able to capture enough of it to make this possible. A big reason for this is that many people are still sceptical about the pros and cons of solar PV systems. By installing solar PV or solar photovoltaic panels on your roof you can harness the sun’s energy to power your home electricity and even an electric car. This can help to significantly reduce your energy bills and, because you will be using less fossil fuel-generated electricity and petrol/diesel, reduce your carbon footprint.

如果你决定是否你应该d be investing in solar energy for your home, here are the most important pros and cons to consider.

Pros of Solar PV Systems

可再生能源对地球更好

虽然这是一个大的声明,安装太阳能电池板的主要专业产品是通过使用更可再生能源并减少对化石燃料的依赖,加入对抗气候变化的斗争。化石燃料不仅耗尽,而且当我们在家庭中使用天然气或石油时,汽车或电力生产我们正在向大气中添加碳,这是导致我们气候变化的温室气体之一。太阳能电力不会产生排放量和(根据科学家介绍)将不会耗尽至少几十亿年。

太阳能光伏系统可以显着减少您的能源票据

Solar PV systems can generate a significant amount of the electricity you need in your home and, as this electricity is free, you will need to buy less from your supplier. The amount you’ll save will depend on how many panels you install, how much sunlight your home benefits from and how much of the solar electricity you are able to use. If you are not at home during the day when the electricity is being generated anything not used will be fed into the national grid. However, if you also install a solar battery to store the electricity you don’t use during the day so you can use it at night, you can maximise your savings.

Solar PV systems qualify for payments from the government

从1月2020年1月,安装MCS认证(或同等)太阳能光伏电池板的房主或企业将有资格在智能出口保证下收到政府的付款。这意味着您将收到您的面板从能源供应商产生的每一个电力的付款。

太阳能光伏系统可以电动汽车

If you have or are planning to get an electric vehicle, you can get a home charging point installed and power it with solar electricity, i.e. you can run your car for free!

Solar PV systems are easy (and cheap) to maintain

您唯一需要考虑的维护偶尔会清洁太阳能电池板,以确保它们尽可能多地阳光。这可以由您或专业公司完成较小的费用。太阳能电池板通常包括25-30岁的制造商的保修,而逆变器通常保证5-10年。由于太阳能电池板没有移动部件,磨损并不是一个问题。

太阳能光伏技术比以往更有效

Solar panel efficiency has improved rapidly since they first hit the market and now the best models can reach efficiencies of up to 25%. The efficiency will decrease as the cells in the panels degrade over time, but the manufacturer will guarantee a minimum efficiency for the warranty period.

Solar PV systems will generate electricity even on cloudy days

由于我们有多少阴云天,太阳能光伏在英国没有生效。虽然午睡的房屋是能够产生更多电力的,但只要有阳光,即使在阴天的日子里,他们也能完美地工作。

太阳能光伏面板成本迅速下降

The cost of solar panels has dropped year on year and today are over 60% cheaper than they were in 2010. Find out more in How Much Do Solar Panels Cost?

太阳能光伏面板是沉默的

太阳能电池板根本没有噪音,因为它们安装在屋顶上,根本不会影响您的日常生活。

Solar PV panels can add value to a property

Many home buyers see solar panels as a pro when looking for a property to buy as they can look forward to cheaper energy bills.

太阳能光伏系统的缺点

Solar PV panels have a high upfront cost

While prices are lower than ever, installing solar panels, inverter and wiring still requires a significant investment of £6,000 on average which can be a barrier for some people.

Solar PV panels won’t generate electricity at night

太阳能电池板只会在暴露在阳光下产生电力,因此在黑暗之后您不会有电。当面板产生更多的电力时,剩余电力将进入国家电网。在白天和晚上在家中,尽可能多的人在家中,这可能会造成问题。

However, if you install a solar battery alongside the solar panels you can store the surplus electricity from the daytime so you can use it at night and increase your savings. Find out more about solar batteries.

太阳能光伏面板在阴天效果效果较低

While solar panels will still generate electricity on cloudy days, the efficiency level will drop which will reduce your savings.

Solar PV panels require a lot of space on the roof

Solar panels should be installed on a south facing roof for maximum electricity generation and do take up a lot of space on the roof, especially if you want to install enough to cover most of your electricity demand. In addition, some people don’t like the look of solar panels on a roof which is a matter of personal taste, but it is possible to install ground-based solar panels in some cases.

是一个太阳能光伏系统适合您的选择吗?

尽管考虑了这些考虑,但在大多数房主的投资是大多数房主的巨大举动,希望减少电力票据,并减少能源供应商及其价格上涨。太阳能电池板比2010自2010从此便宜,并且有可能为您的财产增加价值。此外,当智能出口保证生效时,您还将为光伏系统产生的能量赚钱。
