naa sa may Sugbutel sa reclamation, sa 3rd floor I think, ask lang. I have been there. They have 250w mono crystalline panels for 20k. They have pretty much everything you need to setup like panels, inverters, batteries, charge controllers, and LED bulbs.
For a basic setup, mag grid-tie lang ka para dili kaayo mahal imu expense sa batteries. Ang battery man gud maka mahal aside sa panels. How much can you save you ask? Based on personal experience sa province, a 240w grid-tie reduced a 3000 peso per month electric bill down to 700 pesos per month. It is that much.
The only drawback sa panels is if you happen to buy the cheap ones na mo deteriorate dayun ang quality within 1 year. Sunpower panels are good and also Ying-Li and most especially the German made ones which are quite pricey na.
I honestly would not recommend the CDR King ones for house installation based on personal experience with them na dali ra mo peel and warp. I just cant say that I would trust anything electronic or electrical stuff made by CDR King. Kung back-up charger or pang camp charger ra imu gamitan, then pwede2x ra ang CDR king na panels. Also, I don't know why but their panels have a tendency to bleed.
