Suntank Solar

I live in a retirement village where most of us have Sun tank Solar installations. Suntank Solar completely failed to respond positively to requests for assistance with inefficiency issues. In a recent routine they spilt solar fluid over my lawn killing the grass. They told me I needed to replace my geyser, because it was leaking. An independent maintenance specialist found no evidence of leakage. No attempt has ever been made by Suntank Solar to properly clean the solar panels of dirt and grime.
