Premium installation.

Every installation is the same right? Wrong. Many 3kW solar system installations fail to consider performance increasing factors and system life enhancements. Even though potentially complying with Australian Standards, 3kW solar energy systems which have lacked the adequate time allocation to perform the installation or attention to detail to maximise the solar orientation are compromised from the beginning.

A performance enhancing installation performed by PSW in-house technical staff (no-subcontractors) ensures the maximum power generation and ultimate satisfaction from your 3kW solar system which you deserve.
