The solar lights I put out each morning to charge and move them inside at night and they are almost as effective as candles. That means not having to use the inverter to supply lighting unless I rally need a lot of light (which is seldom)
Also note the Rayovac AA battery pack. Those are standard batteries, BUT they will recharge and discharge daily for months before needing to be tossed. They are much cheaper than NiCad batteries and there is much less garbage footprint by using them for a long period of time instead of once and chunking them. I don't know if the same goes for any other brand of batteries, but I have used the same batteries in the spotlight in the next picture for 5 months straight with them being charged and discharged daily for that length of time. Its a fact that the Chinese NiCad batteries that come in the cheap solar lights don't have a very long life span in most cases and American NiCads can get pretty expensive so why not take the cheap way out for cheap Chinese lights?
As for the new battery bank configuration it is working very well. For one I have stopped using the 22 inch monitor to watch movies at night and don't use the sound system, but I still watch them on the laptop screen which can still be seen and heard pretty well from the couch. I watch movies until 10:30 or 11:00 each night and then shut down everything. The bank still has a decent charge in the morning when the sun is high enough to start charging again and I can use the laptop to be online in the mornings now without ever running the charger. I can run the laptop all day if I care to and the bank is still fully charged by noon. The other solar lights in the first picture supply enough other light in here to make it comfortable and they also get charged during the day.
Oh and just wish'in
