The firm then moved into producing their own panels, evolving into a vertically integrated company controlling the entire process; from refining polysilicon to assembling the final product.<\/p>\n<p>Tongwei opened an Australian office this year in North Sydney, but their panels were being installed here for a few years prior.<\/p>\n<p><a href=\"https:\/\/www.solarquotes.com.au\/panels\/tw-solar-review.html\">TW Solar panel reviews<\/a> here on SolarQuotes from Australian customers have been generally positive to date, with the company averaging a 4.9 star rating. However, we only have a few dozen customer reviews so far, compared to some of the longer established brands in Australia that have hundreds \u2014 and some with thousands \u2014 of reviews. The company is currently listed as a <a href=\"https:\/\/www.solarquotes.com.au\/solar-brands-trust.html\">SolarQuotes approved solar panel brand<\/a>.<\/p>\n<p>Among other manufacturers to release high-power solar panels suitable for Australian rooftops this year are <a href=\"https:\/\/www.solarquotes.com.au\/blog\/risen-475w-panel-mb3281\/\">Risen Energy<\/a> (475 W), <a href=\"https:\/\/www.solarquotes.com.au\/blog\/aiko-launches-its-most-ruthlessly-efficient-solar-panel-yet\/\">Aiko<\/a> (480 W) and <a href=\"https:\/\/www.solarquotes.com.au\/blog\/winaico-bdx-wbc-solar-panels-mb3250\/\">Winaico<\/a> (475 W). Risen and Aiko tend to cater towards the budget end of the market, with Winaico being more middle-of-the-road on pricing.<\/p>\n<p>Learn everything you need to know about <a href=\"https:\/\/www.solarquotes.com.au\/panels\/\">choosing the right solar panels for your home<\/a>; or check out some other <a href=\"https:\/\/www.solarquotes.com.au\/panels\/efficiency\/\">high-efficiency modules here<\/a>.
