What a monitored 2.72 kWp Tarlac rooftop produced
A published monitoring study recorded 3,699 kWh of annual generation from a 2.72 kWp grid-connected rooftop system in Tarlac City.
First-year output from an 11.76 kWp Southern Leyte project
A DOE-documented orphanage project produced 15,876 kWh in its first year, equivalent to about 1,350 kWh per installed kWp.
A mixed residence-and-office rooftop in Marikina
A DOE-documented 11 kWp residence-and-office system recorded 15,930.3 kWh of annual output and an 83.5% performance ratio.
Why two Metro Manila rooftops can produce different yields
A 6.16 kWp Meralco pilot in Pasig produced 6.87 MWh in its first year—lower specific yield than the documented Marikina example, illustrating site and period variability.
An off-grid Cebu project where usable energy differed from potential
A study of a 7.92 kWp off-grid system serving 11 households estimated 6,510 kWh of potential annual energy but 4,674.5 kWh of usable supplied energy, showing the importance of storage, load matching, and operating constraints.
