While cheap budget systems are replaced after as little as 3 to 4 years, quality systems can last more than 25 years. Our systems are designed such that the system and installation costs are recouped within 1 to 3 years, after installation. As long as the system inverter continues to operate, the 25 year product warranty with Bruem Energy panels, means you are very likely to continue making significant savings for more than 22 years after all your initial system costs have been covered.
