小科技 大变革 Simple Solar Tech Generates New Lives

 For most of us nowadays, worried about the details of everyday life such as meeting work deadlines, paying the mortgage or choosing where to go on a vacation, it’s hard to contemplate some of the more basic constraints of life. Yet an estimated 1.2 billion people, roughly 16% of the global population, do not have access to electricity and many more suffer from supply that is irregular and of poor quality.[1]  Around four fifths of these are predominantly in rural areas and whilst still far from complete, progress in providing electrification in urban areas has outpaced that in rural areas two to one since year 2000.


As recently as 1991, 10% (1.15 million people) of the Chinese population was without electricity. China has, since 2014, managed to link all its population, both urban and rural to an electric supply, mostly though massive increases in the reach of the supply grid, but for countries without the same huge economic growth potential as China, meeting such a basic need remains distant. 

With the rapid recent developments in solar technology and battery capacity, the opportunities to bring sustainable, cheap electric supply to rural areas has been life changing for many rural communities. With such large world populations still in need, and climate change restricting development options, decentralization of power supply seems and obvious solution, and one where China’s belt and road initiatives could see profound investment from its renewable knowledge sectors.

 

当今时代,我们绝大多数人都忧心于日常琐事,忙着赶工期,还房贷,或寻思去哪儿度假,因此很难去思考现实生活中那些更基础的制约因素。然而,世界上约有12亿人仍生活在没有电的黑暗之中,约占全球人口16%,还有更多人所使用的电属于非正规、低质量类型。[1] 这之中大约4/5的人口都主要生活在农村地区。尽管中国离城市全面电气化的目标仍然相距甚远,但自2000年以来,城市地区的电气化进度已经达到农村地区的两倍。

哪怕到了1991年,中国也仍有115万人用不上电,占总人口10%。自2014年开始,中国设法实现了电力全覆盖,但大部分情况下都是通过大幅延伸电网的方式进行,其他国家没有中国这样巨大的发展潜力,因此满足该项基本需求仍旧遥遥无期。

随着近年来太阳能技术及电池容量的快速发展,低价可持续电力供应方式的引入给许多农村社区带来了巨大的变化。鉴于世界还有大量人口亟需用电,而气候变化又限制供电选项,因此,分散式电力供应似乎成了一个不言而喻的答案,而且在中国一带一路倡议中,可再生能源领域对该电力供应方式也投入巨大。

Another beautiful morning in Africa and residents of a remote South African community emerge excitedly from their dwellings, gathering around a truck loaded with solar panels. Rapid technological development has brought green, cost-effective alternative electricity options to numerous African towns and villages like this one, that are away from existing power grids. Until recently the only option was waiting for governments, municipalities, or utility companies to find it profitable, or politically expedient to bring electric power to them. Residents now have new electricity options available through solar systems. 

 

又是一个美丽的早晨,南非一偏远社区的居民纷纷从家中欣喜走出,团团围在一辆满载太阳板的卡车前。科技的飞速发展给无数个这样的非洲城镇带来了绿色环保、性价比高的另类用电选项。这些地方离现有的电网相距甚远,不久前,当地居民只能坐待政府、当局或水电热力公司出于政治需要或盈利需要将电力迁至该处。可如今,他们手头已经有了新型供电工具——太阳板。

 

African countries are actively seeking to reduce poverty and social disparity, however huge challenges lie ahead, with sometimes as much as 30% of rural dwellers not being connected to electricity provision and being able to benefit from the potential economic opportunities it provides. 


非洲多国正竭力减少贫困,缩小社会差距。但由于30%的非洲农村人都无法获得电力供应及其带来的潜在经济发展机会,因此上述目标的实现仍然挑战重重。

 

 

Affordable and convenient solar energy generators can allow people to power lighting and appliances such as fans, phones, computers, and other daily life necessities. 


而有了低价方便的太阳能发电机后,人们便能给照明设备及移动电话、电脑等日常生活必备家电设施提供电力支持了。

 

Power supply is also undergoing revolution in well-developed regions however the opportunities to manifestly change lives are compelling in the rural world. Self-generation is on the rise and the population faces more choices than ever, forcing power companies to change their business models and look to create new income streams.  

 

在电力为乡村地区带来许多显著提高生活质量良机的同时,发达地区也掀起了电力供应的革命。自己产电的方式正在兴起,人们面临的选择比以前多得多,迫使电力公司改变商业模式,创造新的收入来源。

 

Compared with the financial and logistical challenges of power grid expansion, decentralized power supply is considered cheaper, faster, and easier to get started and becomes a viable solution to individuals, communities, private sector initiatives and governments. 

This SA Government funded project of US$1.5m aims to supply 30,000 units over a three-year period to 600 villages in three phases. The project supplies 20w solar systems/generators to 20,000 homes in the most rural areas, and 10,000 units of higher capacity 100w / 250w to homes and families with an ability to establish economic bases.

 

Phase 1: Supply 6,000 homes with 20W solar systems/generators, and 3,000 residential dwellings with 100W solar systems/generators. (complete)


Phase 2: Follow up with similar quantities 6-8 month later. (in progress)


Phase 3: Supply 10,000 units of bigger solar systems/generators up to 250W, and focus on income-generating applications (retail outlets). 

 

从财政与运输两方面而言,电网延伸都会面临不小挑战,相比之下,分散式电力供应更低价,更快速,也更容易开工操作。因此对个体,社区,私企项目及政府而言,都是一个切实可行的解决方案。

南非政府划拨了150万美元的项目资助金,分三阶段连续3年为600个村庄提供30000台太阳能发动机。该项目为最偏远乡村的20000户人家提供20瓦太阳能发动机,并为有能力发展经济的家庭提供10000台更高功率(150瓦/250瓦)的太阳能发动机。

第一期:为6000户人家供应20瓦的太阳能发电机,为3000栋居民楼供应100瓦的太阳能发电机。(已完成)


第二期:继第一期结束后6-8月,继续供应太阳能发电机。(进行中)


第三期:供应10000台高达250瓦的大型太阳能发电机,专注于可带来收入的盈利方式。(零售渠道)


Solar systems also have great potential in creating water availability for drinking and irrigating purposes in rural and arid locations. Solar powered pumps are able to both generate and divert water easily and cost effectively.


在乡村干旱地区,太阳能系统也有巨大潜能,可引入饮用水或灌溉用水。太阳能光伏水泵能轻松便捷地产水引水,而且性价比高。

 

Governments are become major beneficiaries as solar panels become increasingly less expensive, and can be rapidly deployed compared to bringing electric power from the grid, which in many cases could be hundreds of miles away. Governments are launching incentives for solar system installation without worrying how long it will take to recover the initial investment (ROI) since in many cases, the choices remain between constant darkness and instant light.


随着太阳板愈发低价,而且相比延伸电网的方式(通常需要延长数百英里),更为快速便捷,政府也成为了主要的受益方。政府出台鼓励政策,促进太阳能系统的安装使用,丝毫不用担心多久后才能收回初始投资,因为在许多情况下,选项只有两个,要么持续黑暗,要么立即供电。

 

 

Government staff provides training courses to communities in each of the towns on how to install and use the generators.

 

政府人员在城镇社区内提供培训课程,教导人们如何安装使用太阳能发电机。
