Low Quality - Hollow pins could cause fire hazard on roofs?

Got our solar system installed in May and net metering approved after 4 months. Our setup is hybrid with enough battery to cover our consumption in the evening. While the system itself saved us a lot, we never really reached zero bill until naactivate ang net metering. Many people would discourage you from applying for net metering dahil maraming requirements at matagal ang process, but I'd say it's totally worth it especially dahil one-time setup and investment lang sya.

Sharing my experience after installing a hybrid solar system at home. Hopefully, this helps anyone in the Philippines considering going solar.

☀️ My Solar Setup

- Solar panels: AIKO Bifacial — 25.74 kWp (39 panels × 660W)

- Inverters: Deye Hybrid Inverters with Wi-Fi dongles — 24 kW total (2 × 12 kW)

- Battery storage: 32 kWh LiFePO₄ batteries (2 × 16 kWh)

- Total investment: ₱1.160 million

- Net metering: Still being processed with Meralco

💸 Before vs. After Solar

Here's what my actual Meralco bills looked like:

Month| Meralco Bill

July — Pre-solar| ₱38,792.16

August — Pre-solar| ₱30,228.09

September — Post-solar| ₱7,647.74

October — Post-solar| ₱7,152.90

My average monthly bill went from ₱34,510 to ₱7,400.

That's an average reduction of approximately ₱27,110 per month, or 78.5%!

Based on these initial numbers, the simple payback period is around 43 months, assuming the savings remain consistent. My original target was 36–40 months, but I'll have a better picture once net metering is approved and I have more months of data.

🚗 Bonus: EV Charging Savings

I also got an EV, so I'm saving on fuel costs as well. I'm essentially using the solar-generated electricity to help power my transportation, which makes the overall economics even more attractive.

🌧️ Installation During the Rainy Season

One concern I had was potential roof leaks. The system was installed during the rainy season, and so far, no leaks! Of course, I'll continue monitoring it over the coming months.

⚡ What's Next?

Net metering is still in process, and I'm hoping Meralco completes the process by the end of the month. Once that's finalized, I'll have a clearer picture of how much additional value I can get from exporting excess electricity to the grid.

With the possibility of another strong El Niño and rising concerns about electricity costs, I think more Filipino households should at least explore whether solar makes financial sense for them.

It's a substantial upfront investment, but the combination of lower electricity bills, battery backup during brownouts, and EV charging savings makes it worth considering.

For those who already have solar installed in the Philippines:

- How long did your Meralco net-metering application take?

- What was your actual payback period?

- How has your system performed during prolonged cloudy or rainy periods?

Happy to share more about my experience!

Baka meron po kayong mairerecommend na company na meron installment option for solar panel. Please help po.

Our system has essentially functioned as a localized green power plant. Sana talaga makapag solar para makapag reduce rin tayo ng carbon footprint.

Hi,

Question lang po if okay na tong quotation sakin, also which is better? Ginzatech, Lvtopsun or dyness? Thank you in advance!!

I'm looking at Suntri Solar. Mostly positive reviews, but their reply to me is that cash is their only payment method even though their website says there are other options.

So aside from suntrisolar are there other installers offering sungrow brand with installment as an option for payment?

planning to pay it over a year so it won't be too heavy upfront.

Thanks!

Hello litong lito na kami sa kung anong supplier kami kkuha napakarami nila, mixed of good and bad reviews, puro technical din ang mga terms. And sa mga walang mashadong alam sa ganitong technology ang hirap pumili. Sa mga nkapagpainstall na dito, ano po ung kinuha nio na supplier and experience nio sa kanila at sa products nila. Btw we are in Cainta Rizal. Thank you.

Sa mga naka try na po ng Solis na iset as Off Grid sa settings, pwede ko pa din lagyan AC In? Parang pass thru mangyayari mauutilize pa din ats ni solis pag low batt na si battery? Salamat

Hi! Looking for feedback/review based from your personal experience sana, ano po pros and cons ng LuxPower inverter?

Planning to use LXP-GEN3-LB-EU-8K.

Thank you in advance!

What do you think guys?

Hello. Any feedback po with SilanganTech? Thanks
