I've just gotten started with solar and I'm currently designing a residential installation (5kw from the load analysis). I've gone through the Ekurhuleni municipality's documents on SSEG requirements and have noticed that quite a lot of due diligence is required in addition to NRS and SANS regulations. Is it really worth the headache going grid tied if the benefits are so small? Main motivation for the desire to go grid tied was to avoid battery costs while reducing my monthly bill.
