Please let me know if you think I've made any serious errors in my thinking.

 

Just did a test with one of my 6,000mAh cells which tested as almost exactly 6,000mAh at a 1A draw, when tested at 20A (the highest my tester will do) it tested again at pretty close to 6,000mAh. Cell was quite warm (no surprise) but otherwise happy.

 

Discharge rate, at least when sensible, has little effect upon available capacity. As to whether the life of the cell is reduced ...

The actual power output you take in from your panels depends on many factors. These factors include tilting and orientation of the panels, shading, season, time of the day, geographic location, etc.

Not that hard, assume you'll get half the rated panel power for 6hrs/day and you won't be far wrong.

330w panel x6 divide by 2 = 1000watts or 1 unit/day.

 

But why did you join the forum to revive a topic that's a year old?
