What is the best brand of solar panels in Australia?
The best solar panels are those that produce the most power and last the longest. The most common ranking system for solar cells is called Silver, which pits a cell against all others in terms of efficiency, voltage, current and reliability. Based on this Sunshine List, Aussie modules (nicknamed 'Solarbac' after Australian company Solarbac) have a Lead Efficiency of 15.5%, but as usage levels go up these low efficiency products tend to lose their top ranking spot since they decrease faster than those with higher efficiencies.
