Rooftop-plus-floating solar scheme nears completion in Cambodia
By José Rojo Martín Feb 26, 2019 11:05 AM GMT 0

A 9.8MW PV project featuring rooftop and floating elements is approaching the finish line in Cambodia, breathing new life into a national PV scene still stuck in the low-double-digit MW region.

Cleantech Solar is building, financing and running a dual PV installation – 2.8MW in panels floating over a reservoir plus a further 7MW across rooftops – to power a production plant owned by the Chip Mong Insee Cement Corporation (CMIC) in the Kampot province.

PV Tech understands the floating element is now fully built while the rooftop portion is nearing completion, with plans for the PV plant to become fully operational by late March 2019.

Cleantech Solar, the builder of 200MW-plus of solar capacity in Southeast Asia and India, expects its rooftop-plus-floating scheme to generate 297GWh in power. The project should slash CMIC’s CO2 emissions by 197,000 tonnes throughout its lifespan, said the Singaporean developer, partially owned by Shell since last December.

Bidders needed for 60MW plant meant to revive local PV scene
Once it is up and running, the project is set to bolster Cambodia’s still modest PV ecosystem. Capacity has steadily risen since the early 2010s but barely surpassed the 27MW mark in 2017, according to IRENA.

With the help of the Asian Development Bank (ADB), the country is working to build large-scale solar into an energy mix still heavily reliant on coal, hydro and imports from Vietnam and Thailand.

The development financier supported in 2017 the country’s first large-scale PV solar scheme. Slated for construction by Sunseap Group, the 10MW Bavet farm is set to supply power to Cambodia’s electricity regulator EDC under a 20-year PPA.

Even more significant is the ADB-backed 100MW National Solar Park project, which will kick off with the setup of a 60MW plant in the Kampong Chhnang province. Under tender documents published by EDC in mid-February, aspiring developers can table bids until 17 May 2019.

An unclear legislative framework – PV was unregulated in Cambodia until last year – and grid connection bans for low-voltage facilities have impacted C&I solar in particular. As advised by lawyers approached by PV Tech, rooftop developers must ensure they have the necessary building permits and rights to use the site throughout the PPA duration.

Cheap, clean and efficient: The firm leading Cambodia’s solar revolution
Publication date 20 March 2019 | 10:35 ICT

Sitting in her bright and airy 17th floor office, Rithya Menon, Okra Smart Solar’s lead firmware engineer, checks the frequently updating data telling her everything about how well their community services are operating.

“I saw in the data that there was a problem with batteries going down each day. They should be recharging to full power,” she says, referring to Okra’s solar charged batteries running households living off the electrical grid...

‘Plug & Play’
The difference between Okra and a standalone home solar system is that a standalone system consists of a PV panel and battery that provides limited power to one household only.

In most cases, the panel and battery assets are not sized appropriately so up to 50 per cent of solar generation is wasted as batteries become fully charged just after midday and are drained quickly at night time.

In contrast, Okra’s technology connects solar home systems into smart grids which enables energy sharing.

This means panels and battery sizing does not significantly affect a household’s ability to scale their energy consumption. To do this, households simply needs to “plug” into a neighbouring household on the network, hence “Plug & Play”.

“If we start with one, it still works but it’s a standalone. There is no way to share the power, but if you connect with next house, you can share the power from one to the others and you can also connect more and more houses, and the more you connect, the more they all share together,” says Hannan.

“It’s as simple as plugging a cable from any of the houses into another Okra controller. As soon as they’re connected together, Okra software activates and starts sharing power in the smart network.”

Okra smart grids are used to provide energy for lighting, mobile phone charging, cooking, fans, television and even refrigeration. In the future, Okra aims to make sure their products can meet demand for more power-intensive electronic devices such as air-conditioners, washing machines, e-vehicle charging and other modern appliances.

Right now, 101 households are connected to energy from Okra smart grids in the most rural areas of Takeo and Kampong Speu provinces. The locations in both provinces are far from existing grids and the communities had no power before they were connected to Okra.

2.8MW in panels floating over a reservoir
Hola!
I've been thinking this is an ideal mix for a long time, a nice flat area for the panels, easy cleaning and cooling
tiered reservoirs would enable solar storage

Gov’t approves 140MW solar project
The government on Friday has urgently approved four solar projects with a total capacity to produce 140 megawatts, a move in to put an end to the country’s power woes in coming years.

The announcement came shortly after a meeting at the cabinet with regard to reviewing and approving a raft of drafts and investment proposals in which the 140-megawatt solar power is also included.

In a statement issued on Friday, the government said the four solar farms will be built in four provinces – Pursat, Battambang, Banteay Meanchey and Svay Rieng – with each solar farm being able to produce from 20, 30 and 60 megawatts, respectively.

And other side benefit are better for fish breeding as they like the dark shade and there would be no fishing boats casting their nets.
Cambodia,,,, Don't fall in love with her.
Like the spoilt child she is, she will not be happy till she destroys herself from within and breaks your heart.
