Hi guys. I am looking to invest in a Titanium element with pv roof panels to heat our geyser. We live in George, WC. Quite a lot of cloudy/rainy days in the year. Also, we live in a rented house (but can move a system as the landlord is not 'funny' in that regard). What has been your experience? Any other suggestions? I know the outlay is quite a lot, but my husband is very handy and can do the installation himself. Thanks in advance!!
