To answer solo, your request on cost of 400watt solar panel if that is what you meant. As I speak to you there are no 400watt panel in this part of the world unless you want to specially import. You can get 200watt solar panel(N170,000 as of last week, price fluctuates).
NB. To deploy solar power to homes, you need solar panels, inverter, deep cycle or shallow cycle batteries,
charge controller and cables. The capacities of all these can be decided after SIZING(appropriate house load calculation).
To answer Ismail; Air conditioner of course can be energized by pure sine wave inverter, except that this inverter type is more expensive than modified sine wave inverter(economical). A true or pure sine wave inverter can power anything like laser jet printers, fax machine, cordless tool chargers etc. A modified sine wave type may present certain compromises by giving humming sounds with some loads.

Carol, the type of solar cell required for us here is mono-crystal not poly-crystal, all other components are very compact able for this part of the country. The power box,inverter, charge controller are all fine except the solar cell made from poly.
