Mahal pa rin nga lang ang upfront cost.....

(I use solar cells, for our garden lighting....)
Sunlight might be free but the system to convert it to electricity is expensive, even with current mass production levels (although I would admit, its much cheaper now than ten years ago). Still the problem is the technology must be able to pay for itself in a reasonable period of time, otherwise only people with "green" intentions would adapt this technology.

Another potential alternative is domestic wind turbine technology. You can install a small scale windmill and use that to charge a bank of electrical storage batteries for later use like night illumination. To offset the shortcomings, the system can be tied in with the national power grid to provide power when the storage batteries go flat.
