Yung d kana man magaling sa math pero nag survive ka ng 5yrs sa engineering 😭, 1 take sa dalawang board exam. Ang galing lang ni Lord.🙏🙌☝🏼.

Some days, the equations won’t make sense. Some problems feel impossible. But you’re still here. And that matters. 👷💬

Best Solar Panels for Hot Weather Conditions, Especially in the Philippines.

1. Choose a solar panels with lowest ambient temperature ( Temp. Coefficient Pmax - Ideally around -0.24%/C to -0.30%/C).

2. Cell Technology (HJT, N type Topcon, PERC), much better if HJT.

3. Low power degradation

4. Strong resistance to humidity, UV exposure, and corrosion.

Always check the datasheet of solar panels before you purchased.

This is the initial testing of the 8.96 kWp Microinverter System we installed 2 weeks ago, and it achieved a production rate of 94.28%. 😍

I’m still studying the comparison of pricing between Microinverter and String Inverter. I came up with the conclusion that Microinverter is higher by around 50k to 100k than String Inverter. But if the String Inverter will add an optimizer and rapid shutdown to have the same functionality as Microinverter, I think this could be the same price, or baka mas mura pa ang Microinverter.

When I started studying and installing Microinverters way back in 2017, when I worked for a solar company, they used a Microinverter system. I saw that this system was very safe and very efficient. At nakita ko na kaunti lang ang gumagamit nito compared sa string inverter. Siguro dahil mas naging popular ang string inverter at mas mura siya compared sa Microinverter. And some installers and solar enthusiasts ask the question kung bago lang ba ang technology na ito. Microinverter technology has already existed for 18 years, so hindi na ito bago.

May mga installers na ayaw nilang mag-install ng Microinverter, maybe dahil sa cost, mahirap i-offer sa client, and also because of some of the disadvantages, like maintenance access and the potential failure of each component. But for me, these disadvantages are solvable. What I like to focus on in this system is the safety, efficiency, and longer warranty. For the 9 years that I have been using it, I have not experienced a single failure, and it is still working until now.

The good thing is that some of our clients who chose this system studied it first before choosing it. That’s why we continue to promote this Microinverter system—to educate people who are interested in this kind of system.

Isa sa mga challenge sa mga solar installer tuwing tag-ulan. Hindi maiiwasan ang delay during installation at minsan lugi na din sa time. Kaya napakahalaga ang planning, at kung ano ang mga dapat e priority pag ganito ang panahon.
