Hi All,
Looking at going off-grid.Use about 250 kw/h per month. Heavy day is 10 vs 5 on a low day(24 hrs). Thoughts are 5kw S/S Inverter and 15kw S/S battery. Sunsynk is the product most of my friends have. Clearly powerdraw would have to be managed.
90% of food prep and cooking happens before sunset.Gas and solar hot water into electric geyser with timer on mains
I am hoping for genuine independent advise from all of you sages so that I can make informed decisions when calling for quotes in East London.
Direct Eskom customer paying R40.00/day for the privilege and R4.50 /unit..With 12% increase each year would be in for ABOUT 200k after 5 years.
Financially keeping Eskom is therefor not an option if wanting to go solar.
Would obviously watch weather forecasts and live accordingly. Two of us over 60 and able to adapt.
Would like to be able to connect 5kva genset to trickle charge while consumption is low in the event of cloud.
I have roof space as follows with no shade issues.
Would like to run existing 2200 watt underfloor heating mid-winter whilst sun shines . Slow warmth release during the evening.
ROOF SPACE.NO SHADE ISSUES ALL DAY
4 panels n/w 26 degree pitch tiles. Mid-winter sunset is direct onto this roof.
4 panels n/e 26 degree tiles
4/6 panels north on a carport to be built with adjustable tilt for winter/summer.
1. Could I do North on MPPT1 and the balance on MPPT2
2. What size panels do I go for
3.Anybody willing to guess what annual increase would be for the next few years
4. I have read on this forum that genset connection is possible as long as Hertz is correct.
5.Would anyone have a guess as to cost of this scenario.PV array about 15 meter away from DB.
6.Any suggestions welcome. Bear in mind capex is from retirement funds.
I am very excited to get any reply
