If you don't mind, who is the supplier and what is the contact number?
Kaya siya 2000 watts kasi yun yung output nung circuit na naka-kabit sa gen set namin noong panahon ng brownout. It's smallish pa kasi experiment pa nga lang. I want to see any downsides to the project, if ever.

Pero kahit 2000 watts lang yun, dahil malakas ang gamit (essential system nga eh), it operates NLT 10 hours a day kaya in 1 month, that's 2000x10x30 wh (60 kwh). I don't remember the cost I used for Napocor but I remember just dividing the Kwh figure by the total bill para kasama na lahat ng taxes, distribution charge, etc.

Take note though -- commercial establishment ito kaya mas mataas ang rate kesa sa households dahil sa commercial establishments yata galing ang lifeline subsidies. Hindi ko kinompute using households as a basis eh.

Solar doesn't cost anything after installation -- yung replacement lang ng baterya every 2-3 years or so. If I remember correctly, I also put that in to my analysis. Thing is, mahaba ang payback niya kaso since 20 years naman ang warranty nung solar panels, huwag lang maaksidente OK na.

I also took note that our power increases in price by around 10% every year. While the cost of the panels decreases by more than that every year. So talagang eventually, only the large initial cost will be a hindrance. Hinihintay ko sana magka-subsidy ito pero mukhang wala pang liwanag sa gov't kaya mauuna na me! harharhar!
