A Pakistani-Chinese research group has demonstrated a new maximum power point tracking method, based on a fuzzy logic algorithm to provide faster results. The converter tech is claimed to have an impact on PV system efficiency and provide isolation between the load and the PV array.
A Pakistani research team has assessed the performance of a passive heat sink cooling technique in two different configurations: one using rectangular fins and one based on circular fins. The rectangular configuration was the best in terms of heat rejection. Modules mounted with this solution had a 6 C lower temperature than modules without cooling systems.
Solar and wind are expected to account for a growing share of the electricity mix in the years ahead, rising from around 3% at present to 23% by 2030. Over the following two decades after that, however, this share will likely remain unchanged, as the national regulator expects the country to deploy more coal-fired generation capacity.
Researchers in Pakistan have evaluated the impact of shading on inverter set-ups to assess PV system performance. Tests were conducted on a 51 kW system featuring SMA inverter topologies but the researchers say the findings could be applied to products from other manufacturers. The results showed the number of maximum power point trackers is important but levelized cost of energy calculations are also crucial to selecting the right inverter configuration.
Solar deployment continued to pick up in the Middle East and North Africa in 2019, the Middle East Solar Industry Association has said in its annual report.
By this time next year we may be able to wave goodbye to that old chestnut about renewables endangering security of supply. Elsewhere, the price of lithium – and the products it goes into – could go either way after tanking this year.
Italian oil and gas company Eni has completed a solar park at its Bhit Gas Field. The plant, which took six months to build, is integrated into the field’s generation system.
