Belgotex Floorcoverings: Solar Panel Installation The largest roof-mounted solar power system in SA installed by Belgotex Installation of 12,000m2 (1.2 hectares) of photovoltaic (PV) solar panels commenced at the Belgotex factory in Pietermaritzburg, Kwa-Zulu Natal in July and is expected to generate around one megawatt per hour of electricity. The latest initiative in the company’s ongoing ‘Green Journey’; the project is intended to reduce their reliance on the national electricity supplier and move them towards sustainable energy sources. Solar energy is considered the cleanest, most viable alternative to fossil-based fuels and plays an important role in decarbonising the global economy. Over four thousand solar modules – equivalent to one and half rugby fields - will be installed on Belgotex’s 100,000m2 factory roof tops at a cost of R17mn, providing about 5% of the giant’s annual energy requirement. The daily energy generated is estimated to be sufficient to power 700 average households, with an expected five- to seven- year payback. With increasing petroleum/coal prices, peak load penalties for Large Power Users and a 10% annual increase for utilities projected by Eskom, selfgenerated solar power has obvious advantages for both operational costs and environmental management. PV panels are active solar systems that utilise supply-side technology to generate alternative energy, whereas passive solar systems, for example, using natural sunlight for heating, merely reduce the demand. Multi-crystalline solar panels harness the sun’s energy during daylight hours, converting sunlight into electricity through the photo-electric effect, a process similar to photosynthesis in plants. The low maintenance requirements, autonomous operation and a long life expectancy make solar power systems ideal for on-site renewable power generation. Belgotex boasts enough north-facing roof surface to cover 50,000m2, with plans to roll-out a second and possibly third phase over the next 5 years to meet their own requirements. This would eventually enable to the company (once legislation changes), to feed power back into the national grid by selling their excess electricity back to Eskom during weekends, shutdown periods or power outages. The move is also expected to reduce the company’s future Carbon Tax liability by between 5 – 10% due to the 1,386 tons of CO2 emissions saved each year from not having to rely on coal-produced electricity. www.belgotexfloorcoverings.com Call 033 897 7500 or CT: 021 763 6900 or JHB: 011 380 9300 A FUTURE OF POSSIBILITIES ON A GREENER HORIZON AT AFRISAM, WE DON’T JUST CONTRIBUTE TO ECO-FRIENDLY STRUCTURES THROUGH OUR LOW CO2 ADVANCED COMPOSITE CEMENT, WE CREATE SUSTAINABLE POSSIBILITIES.
