Demand for monocrystalline solar cells demand is increasing as PV rooftop markets switch to self-consumption, according to EnergyTrend, a research division of TrendForce.
Higher efficiencies provided by monocrystalline cells/modules, compared with multicrystalline alternatives, are expected to be in strong demand in both Europe and Japan, where self-consumption both at the residential and commercial markets continues to gain traction.
EnergyTrend reported that Taiwan-based tier one solar cell producers shipments of mono-Si cells had increased from 5% at the beginning of the year to more than 20% of total shipments by the end of the second quarter.
Strong demand in Japan is expected to see further shipment increases in the second half of the year as momentum builds into the first quarter before feed-in tariff changes are expected.
The market research firm noted that Taiwan-based tier 1 solar cell producers were providing mono-Si cells with conversion efficiencies above 19.2%, with the expectation that efficiencies would continue to increase through to the first quarter of 2014, reaching and average of over 19.4% in that time frame.
EnergyTrend also noted that due to FiT changes in Europe, the rooftop market was set to become increasingly important, already accounting for about 80% of installtions.
As a result the global rooftop market accounted for 53% of the global market in 2012, yet was expected to account for nearly 60% of installations by 2014.
Increased demand for mono-Si products would therefore follow this trend.
