I'm also looking at solar, so tips appreciated. Our options at the moment have been narrowed to:
- Rent via Gosolr or Versofy. So far Gosolr, with 14 panels, 8kW inverter, and 2 x 5.5kW batteries looks better specced and R300 cheaper per month than Versofy.
- Purchase using the new FNB Solar home loan addition. Uses a pre-approved portion of home loan to purchase a solar setup from four approved suppliers, being LTM Energy, Erinite Energy, Averge Tech, and Ingwe Projects. Erinite looks useful, with a sample system on the website for about R230K. The other three look like project managers or equipment suppliers who do quotes on demand, so no sample pricing.
Renting - no serious upfront payment, could come very close to not costing us much extra per month, built-in maintenance, some but obvious disadvantages (cancellation penalty, and no ownership of the system.
Adding to home loan: likely cheaper in the long run, given interest rates, ownership of system, increases property value, but could be more per month, potentially over a longer period.
Any comments on running geyser(s) or oven off solar? Not a good idea? We could get solar geysers, but then maybe it would make sense to up-spec the initial system and run it off that.
We'd like to run as much of the house as possible. At the moment we have (effectively) a 2.4kW inverter that can run most of the house (except a few plugs, outside lights, pool pump, geysers, and oven) for about 7 hours.
