We recently replaced our older solar panels and added some more. We have also just added a battery. It is 15kw.
The great beauty of installing it is we get to see how much energy we produce, how much goes to the battery and how much we take from or add to the overall system.
I am amazed just how much power we get even on a cloudy day and even when the sun is setting. We do not use any from the system on a cloudy day and as the sun sets we still get some power from the solar panels. We are reliant on the battery but as you would expect we do not use as much as we would without it.
We do not use up the battery overnight even after preparing the evening meal and most taking showers.
although the reheating of the hot water for showers was expected there are other times where we are using power and there seems no feasible reason for it. Perhaps there is a lag at work. I need answers to questions.
Thus far we have not experienced a day where the temperature has got near 30 degrees so it only goes up from here. Of course it will be interesting when we are in winter!
I will update once we have had a lot more experience with it.
A few more questions. how come all of the power from the solar panels do not go straight into the battery. Why does some of it go into the system?
Today the temperature has not reached 20 degrees yet despite starting at 5% capacity we are at 90% just before 10 am.
