Solarcentury gets project down to a tea
A 1MWp solar PV project is bringing clean green solar energy to a Kenyan tea farm.
Williamson Tea has reported that it has opened East Africa’s largest solar project at its Changoi Tea Farm in Bomet County, Western Kenya.
The solar system will cut Williamson Tea’s energy costs by around 30%, supplying clean solar electricity during the daytime to meet most of the tea processing factory’s energy demand. Williamson Tea’s system will reduce the need for grid electricity and the consumption of diesel when back‐up energy production is required. This innovative use of solar engineering is only the sixth system of its kind to be built in the world.
Solar energy company Solarcentury was selected as the lead designer, supplier and installer of the unique PV system, and is also responsible for the operation and maintenance. A British company and expanding internationally, Solarcentury is committed to bringing the many benefits of solar to Kenya. Solarcentury has invested in Kenya by having a Nairobi office, headed up by Dr Dan Davies, one of Solarcentury’s founders.
Williamson Tea’s solar farm will work in parallel with the grid and reduce the amount of grid electricity imported. When the grid is down, the solar power system will work together with the standby diesel generators, significantly reducing the amount of diesel consumed.
Commenting on Williamson Tea’s solar farm, Dr Dan Davies, Director for Solarcentury said in a country blessed with plentiful irradiance and land space, solar is a perfect solution and reduces dependence on fossil fuels while improving energy security.
Frans van den Heuvel, Solarcentury CEO, said, “Williamson Tea’s solar farm in Changoi is a shining example of the opportunity for solar in Africa, and indeed the emerging markets, to help meet the increasing energy demands of growing economies.”
Local solar companies East African Solar and Azimuth Power were the developers for the solar project.
SolarCity, Capital One form $100m fund

To date, Capital One has issued more than $3.5bn in energy-banking loan commitments.
White House walks the talk on solar
The United States White House released a new video highlighting the installation of solar panels on the roof of the residence. Every aspect of the White House solar installation was domestically sourced -- from the solar components to the inverter technology to the labour that put the panels on the roof. The finished product, a rooftop solar array generating clean electricity, symbolizes the building momentum for solar across the country, said a US Department of Energy press statement.
“Solar panels on the White House, I think, are a really important message that solar is here,” said Secretary Moniz, who was featured in the video along with Minh Le, Director of the Energy Department’s SunShot Initiative.
However, US Department of Energy Secretary Moniz says, “We can do a lot more.”
President Obama has announced new efforts, including commitments from more than 300 organizations to expand the use of solar energy new solar commitments.
The commitments represent more than 850 megawatts of solar deployed as well as energy efficiency investments that will lower bills for more than 1 billion square feet of buildings.
Additionally, the President announced new executive actions that will lead to $2bn in energy efficiency investments in Federal buildings; smarter appliances that will cut carbon pollution by more than 380 million metric tons – equivalent to taking 80 million cars off the road for one year – and will save businesses nearly $26bn on their energy bills; and training programs at community colleges across the country that will assist 50,000 workers to enter the solar industry by 2020, said a White House statement.

Robot cleans one million panels
Soiling – the accumulation of dirt and dust on photovoltaic solar panel surfaces – is one of the greatest impediments to solar energy production efficiency, and can reduce solar panel energy output by up to 35%, according to Ecoppia, an Isaeli developer of autonomous water-free photovoltaic solar panel cleaning solutions.
The company has recently reported that its commercially-deployed E4 robotic cleaning system has cleaned over one million panels to date.
Ecoppia claims that it is the only market player deployed at this scale and “presents a paradigm shift”; which is a move away from existing labour-intensive, water-based, high-risk panel cleaning solutions.
The autonomous energy-independent water-free E4 robots use a soft microfiber and controlled air flow cleaning system to remove 99% of dust daily, keeping panels at optimal production 24/7/365.
Eran Meller, Ecoppia CEO, said, "We are on track to meet and exceed our expansion plans, such that Ecoppia robots will be cleaning 5 million panels a month by the end of the year, while adhering to the highest standards of operational excellence and customer satisfaction."
Heraeus Photovoltaics introduces new pastes
The Heraeus Photovoltaics Business Unit, a supplier of metallization pastes for solar cells, is launching two new front-side metallization pastes for standard to ultra-lightly doped emitter cells - the SOL9620 Series and SOL9621 Series.
Cell manufacturers may be attracted to the SOL9620 Series and SOL9621 because they claim to improve c-Si cells' conversion efficiencies to an industry-leading level.
By using these new pastes, customers have confirmed efficiency improvements that ranged between 0.05% and 0.20% absolute on lightly doped emitter [90 – 100 ohm/sq.] wafers, relative to the best commercially available front-side pastes.
Even greater gains have been achieved on ultra-lightly doped emitter [110 ohm/sq.] wafers, where the paste unfolds its peak performance, according to the company.
The SOL9620 Series and SOL9621 Series of pastes are able to provide excellent contact on lightly doped emitters [LDE].
