What is the max wattage I can place on the roof,using setec 35-ll
Can I just splice into the existing manufacturer wiring,will it handle the wattage.
What type panel do I use mono or crystal, the ones I have now are black.
Thanks for your advice
When adding SOLAR to an existing setup, it is best to add the same SOLAR panels that you already have (same wattage, same voltage, same mfr, model). The most important thing to remember is that all the panels need to be the same voltage, you can not mix and match panel voltages on the same SOLAR Charge Controller. (There are 17, 24, 36, 72 volt models). Although, you could add a second SOLAR charge controller to handle panels of a different voltage. The SOLAR charge controller you have will have specifications regarding MAX wattage and MAX voltage. An example is my SOLAR Charge Controller, Morningstar MPPT 60. It will allow 150Volts of SOLAR panel output and a max 60 Amps (800 watts). You will need to look up your SOLAR charge controller to see what it can handle. The wiring is another important part of the setup. No you SHOULD not splice into the existing setup. They should be in a combiner box that is designed for connecting multiple panels together. The TT's prewire is not designed to carry a lot of amps, so you will need to see what your TT is prewired with and calculate if the AWG is large enough to carry your panel output.
