I've only seen very few posts regarding solar and its viability as an investment. So here I am to show some actual numbers from our 1st month on solar.
Do note that my solar installation was a semi-DIY venture to cut down costs. I bought solar from a wholesaler, an inverter from Lazada and had them recommend me a guy who does freelance solar installations. I did all the research on the brands, ratings and reviews for each component so that took some time but it was fun and educational.
- By the numbers
Total investment: 226,541.00 (breakdown below)
Total Capacity: 7.5kWp
November data:
Our monthly electric bill averages at around 15k / month so it went down approximately by 30%
- Things to consider
We do not have net-metering installed yet (tinatamad pa eh) but plan to do so in the future and I estimate this would further up the savings by another 2~2.5k php / month. This is estimated from:
Where 5.0 Php/kWh is the rate at which Meralco will buy power from you.
If you want to see our daily power generation on an hourly basis:
- SUMMARY
4 years ROI is about 25% return year on year. Beats any mutual fund, most bluechip stocks and is a pretty low risk investment. You can also get your installation insured for about 3,000Php / year. All in all 100% would suggest.
I'll update these numbers monthly if people are interested.

- Average Daily Generation: 17.5kWP
- November total generation: 514 kWh @ 9.09Php/kWh = 4,672Php

Code:
{(total capacity * 5 hours) - total solar consumption)} * 5.0 Php / kWh * daylight inefficiencies
Where 5.0 Php/kWh is the rate at which Meralco will buy power from you.
