The days' temperature was in the early 30°C's but there was a nice breeze wafting across the solar panels. That made it ideal for power production.
|5.3kWH / 399 AH went into the solar batteries|
|Only 3.42kWH was consumed by our appliances /|
...but we had only used 3.43kWH at 17.58p.m.
That gave us an additional 1.9kWH. More then enough to watch our 60 watt TV until 10.00p.m., power our 180 watt fridge (on it's timer - one hour on, one hour off) through the night, and still have the batteries well charged the next morning :)
Nobody - but nobody - tells you when you purchase a solar system that:
1 The hottest days are not the best for charging solar batteries. If the solar panels get too hot, they don't produce, nor provide, optimum charge to the batteries because overheating reduces their efficiency.
2 The cold winter mornings are also dicey. If the solar panels are too cold due to the ambient temperature, even if the sun is shining on them, they don't absorb the energy to charge the batteries until they warm up. Which could mean 9.30 - 10.00a.m. before they even start supplying charge to the batteries.
But, even with that said, I would not change back to grid power! I'm loving our solar power. Honestly though, it does take some getting used to what can be run on our total 980watt solar panel system, but once you get your head around that, it's a breeze :) And, if we ever find that we need dramatically more power (mainly for power tools) then running the genny for a hour or so takes care of that!
No Escom blackouts in this household LOL
