Soluz can get you what you need. Who is going to install the system? She will need to mount and position the panel properly. It needs to face south, no trees or other objects shading the panel at any point of the day (if possible), at around a 25-30 degree angle, use as big a gauge wire as you can from the panel to the control box and then to the battery and try to leave all lighting DC (hard to replace in Haiti). It is important she learn not to use more power than she produces everyday in order to get the best life out of the battery. With the small systems, a regular car battery is mostly used and should only be discharged at about 20% at the most, preferably less.
