Odd for me to post this because I just installed a 6.5kw solar system, but this is what I have been doing for the past year to do solar on the cheap but effective. I use Nokero N220 and d.light S2 rechargeable solar lights, two of the Nokero over my computer desk, one Nokero over the coffee maker, and one d.light in the kitchen for ambient lighting. These lights are basically task lights and they give the light to do the job without lighting brightly a whole room, but both give sufficient ambient light as well. Set them outside during the day to recharge, and use at night and early morning when light is needed for the task. Two behavioral changes. First, adjusting to use light only needed to do the job, and to move away from brightly lighting big spaces when that light is not actually needed. Much of the world already lives this way. Second, accepting the minor inconvenience of setting the lights outside each day to recharge and bringing them back in at the end of the day. Both of these lights will give about 6 hours of light on a full charge, but sunny days are needed for this, and cloudy days may not give a full charge. A bonus besides reducing the electric bill is that for about $100 you can buy 4 or more of these lights and achieve immediate benefits of solar. Effective solar does not need to be expensive.
