Reading reviews is a very important part of researching a potential solar power or battery storage purchase. If you’re installing a system in Australia, then the experiences of other Australians who have made the switch to solar are particularly relevant.
I’ve collected tens of thousands of reviews of companies and components over more than a decade, creating the largest solar reviews database in Australia. Whether you’re looking for opinions on installers or brands of solar panels, inverters or batteries, you’ll find them on SolarQuotes. Learn more about how the ratings and reviews are collected here.
LONGi Solar is the world’s largest manufacturer of solar panels and has held this position for three years. In the solar industry, that’s a Longi time. But they may not be number one for long. In 2022 they only produced 5% more panel capacity than their closest rival and that’s not a long lead. But the odds aren’t long they’ll remain the top producer for the next few years.
This Chinese company became a solar giant by producing panels with a good combination of affordability and reliability. While some of their panels only come with a fairly standard 12 year product warranty, others are backed up with 25 years. They also produce one of the highest efficiency panels available.
Because they’re reliable and good value for money, LONGi Solar panels are among those SolarQuotes recommends. I’d be fine with having them installed on my mother’s roof. In fact, my co-worker, Anthony, did put them on his mum’s roof.
FAIR TO WONDERFUL HEAT RESISTANCE
Heat lowers the efficiency of solar panels. Choosing heat resistant panels can slightly boost their energy output. In practice, the benefit is usually small and amounts to less than 2% difference in overall generation, but every bit helps.
The loss of efficiency due to heat is given by a panel’s “T
