If you are ready to spend 2000$ a very good solar system can be installed at home. The solar panel will charge the battery. And the battery is used as source of electricity in the evening.  A 2000$ solar system will be able to light 10 CFL each 23 watts capacity. You can also use it of laptop and TV.

If you want just few light bulbs and don't want to use it for laptop and TV a 500$ solar system will be good enough. There are many retailers for these systems in KTM

I believe these solar systems are available in many cities in Nepal, and if you want to install in village you buy the system and install yourself. It is very easy to install, just takes one hrs of training.
