An average residential installation can take between 2 days and 2 weeks, depending on the complexity of the project. Larger installations are solely dependent on the size and complexity of the system. CURE warranties our workmanship for a period of five years after the installation. The workmanship of most system components is covered for five years, 10-12 years for PV inverters and for 15-25 years by the PV module manufacturer’s performance warranty, for example. All installations are followed up with routine maintenance calls when needed (mostly for wind energy systems) based upon the manufacturer’s recommended maintenance schedule. Customers are educated about their systems and are guided through troubleshooting and maintenance procedures once the system is installed through the first year after the installation. Long-term inspection and maintenance contracts are also available after the five year warranty period.
