Technical FAQs 4

Are solar panels reliable?

Solar panels, in general, are very reliable. According to a study, only .05% of PV modules experience failure per year during their lifetime. Where does that number come from? In 2017, The National Renewable Energy Laboratory (NREL) monitored 54,500 solar panels over 15 years.

Do solar panels have higher power ratings?

Despite the publicity surrounding the many high-powered panels, the PV cell advancements that enable these higher power ratings are universal. Thanks to these innovations, regular-size commercial and residential solar panels have also seen a significant increase in power, with 440W to 550W panels now standard.

Are solar panels durable?

In most cases, yes. Solar panel durability is tested to withstand extreme conditions, but factors like dirt buildup, heavy rain, snow, and strong winds can impact performance. Proper installation and maintenance help ensure your system lasts for decades.

Do you really need the most efficient solar panels on your roof?

Larger, utility-scale solar panels can be more efficient than residential panels and technology still in research phases has almost doubled that efficiency. Solar technology keeps getting better, but do you really need the most efficient panels on your roof?
