With grid power costly and patchy, race is on to find innovative ways for households to buy solar equipment
Innovative ways to pay for solar power systems could make clean energy affordable for many of Zimbabwe’s 1.5 million households that lack electricity, campaigners say.
Zimbabwe produces only around 60 percent of the electricity it needs when demand is highest, and relies on costly imports to make up some of the shortage, particularly when drought hits hydropower facilities, as happened this year.
That means solar panels and other clean energy sources not connected to the southern African nation’s power grid are likely the cheapest and fastest way to bring electricity to those without it, say sustainable energy experts.
“Only focusing on grid extension and increasing generation capacity will not allow us to attain energy access for all by 2030,” said Chiedza Maizaiwana, manager of the Power for All Zimbabwe Campaign.
To meet the internationally agreed goal, so-called “decentralised” renewable energy is “a critically needed solution”, she told the Thomson Reuters Foundation.
“It is imperative that we create the opportunity for families and businesses to access (these) services rapidly and affordably,” she said.
Getting connected to the grid in a rural area can cost thousands of dollars, a huge obstacle when many people earn between $20 and $100 a month, said Ngaatendwe Murimba, a programme officer for Ruzivo Trust, a non-governmental organisation (NGO) working to improve rural energy access.
But families without electricity do pay for energy, buying firewood or charcoal – which drive deforestation – batteries, or polluting fuels such as paraffin.
A 2012 study by SNV, a Dutch anti-poverty NGO, found that a rural household in Zimbabwe spends on average $26 a month on lighting, communication and entertainment, including $8 to $15 on kerosene and candles alone.
A home solar system that can produce enough power to run lights, a radio and a television costs about $500, said Honour Mutambara, a renewable energy manager with SNV in Zimbabwe.
That’s one reason only a fifth of households in Zimbabwe use solar energy, he said.
Simba Mangwende, a renewable energy director with the Ministry of Energy and Power Development, told a workshop in June the market for decentralised renewable energy is “abundant but it is being curtailed by deprivation of cheap sources of finance”.
Zimbabwe lacks clear-cut policies and targets for renewable energy, and is still developing a feed-in tariff, deemed key to attracting investor participation in the sector.
If families are to afford clean energy in the short term, innovative business models are needed, such as pay-as-you-go or rent-to-buy solar systems, experts say.
Jonathan Njerere, head of programmes in Zimbabwe for charity Oxfam, said that in Gutu district, 230 km east of Harare, his organisation and others had helped set up a community-owned, self-financing solar energy scheme.
It has enabled more than 270 farmers to irrigate about 16 hectares (39.5 acres) of crops.
Oxfam gave the community solar equipment for irrigation and an initial batch of solar lanterns, which were sold to members. The proceeds were pooled in a savings and lending scheme, allowing others to join and buy solar products for home and business use.
Community funds are used to purchase solar equipment for sale to the public through energy kiosks, and the revenue is kept for repairs and relief in natural disasters.
Njerere said the programme, assisted by 2 million euros ($2.22 million) from the European Union, had helped chicken farms, fisheries, tailors and shopkeepers acquire hire-purchase solar panels, so they can work in the evening as well as during the day.
Other entrepreneurs use the solar panels to sell mobile phone charging services for $0.20 a time.
