Solar PV H1Z2Z2-K Cable should be used for connecting solar panels to inverters or charge controllers as this type of cable is rated to high voltage especially needed for solar panels in series. These cables are for permanent outdoor use for more than 25 years under variable demanding climate conditions.
This type of solar PV cable is also well suited to small wind turbine installations where there will often be a low voltage but high current output making the power generated very susceptible to cable voltage drop even over very short distances of just 5 meters. See link below for voltage drop calculator to ensure you make the most of your generation. Your system design should try and use the highest voltage output possible from your installation (for example series solar panel wiring) as this will help to reduce voltage drop. Larger cable conductor sizes also help to reduce voltage drop.
