Solar makes cents, and Boschendal becomes a significant producer

About two years ago, the V&A Waterfront commissioned 4,207 solar panels (7,000m²) installed on the roofs of the main Waterfront buildings, with a total electrical output of 1,093.8 kWp at a cost of R20 million.  It conserves about 1,721,956 kWh annually, significantly reducing the Waterfront’s environmental footprint.  At the same time, Boschendal commissioned its first, small rooftop solar installation at the Rachelsfontein complex.

Then in October 2017, Robben Island launched its R25 million, 666kWp solar farm supported by 828 kWh battery storage, to reduce reliance of diesel which was shipped in for the island’s generators.  Just based on the cost of fuel savings, the Robben Island installation will pay for itself within five years.  The micro-grid on Robben Island is the largest combined solar and lithium-ion storage micro-grid system in South Africa.

Bucking the trend in the drought

The Western Cape has faced its worst drought in a century, and this is the third consecutive year of that drought.  Cape Town’s mayor has been at pains to point out that — with climate change — “This is the new normal.”

With dwindling water supply to farmers, crop productions have been slashed and, across the Province, between 35,000 and 50,000 jobs are at risk, excluding an even larger number of seasonal workers.  I asked for the provincial department of agriculture’s stats for produce under threat but received no response!  I am underwhelmed!

Minister Alan Winde’s speeches, however, paint a dire picture which are just a tip of the iceberg.  A month ago, Alan visited the West Coast.  “There’s thousands and thousands of hectares of agricultural land below the Clanwilliam Dam which produces a lot of produce and revenue for our country that’s now under severe water restrictions. They’re going to produce 50% less,” he said.  “Farmers are being throttled and are forced to use 60% less water, with the Clanwilliam Dam level at around 36%.  There’s an 80% decrease in potato crops and a drop in wine and export quality citrus.”  With commercial farmers struggling, one focus for Province is supporting backyard food gardens for workers’ food security.

“In places like Ceres, 80% less potatoes and 50% less onions will be planted — resulting in about R40 million less paid out in salaries and wages.  In Lutzville the tomato paste plant will not even open this year.  Some 30 000 animals have been sold as farmers battled to feed their core herds.”

Against this backdrop, Boschendal started out at the beginning of the drought with a massive planting of 600,000 new fruit trees over a period of three years — which has just been completed. Permanent jobs in farming operations alone has grown from 70 to 287.  Their dams are full and Jacques du Toit, Boschendal’s general manager, said the dams started overflowing on 20 August and he counted 15 streams on the farm running into the Dwars River, on to the Berg River, and out to sea… Continue reading
