I want to give a quick thank you to everyone commenting here, I genuinely wasn’t expecting this video to get anything like this level of attention.
I rather naively told myself I’d try to reply to every comment because so many of them have been thoughtful and detailed. After spending several hours doing that yesterday, I’ve realised I may have grossly underestimated the task 😅
I’m still reading as many as I can, and I really do appreciate the advice, questions, corrections and experiences people are sharing. If I don’t manage to reply to yours please don’t take it personally, put it down to my reply fatigue!
Thanks again for all the support and for making the comments such a useful discussion. It’s been quite humbling to see.

Just the part about not having to worry about brown outs make it worth imo

this is a well-researched and data-driven presentation dude- good job! if I didn't live in a condo in Metro Manil, i would definitely have decided on installing solar as well!! power self-sufficiency is priceless! also the fact of potentially selling power to the grid and helping ease the load of the country's humongous power demand, albeit in a VERY small way, is also a plus. plus a small income sounds good on paper too. or at least sero elec. bills for the medium to ong-term future!

Good evening guys, having installed solar 4 years ago and studied the data pattern very similar to yours.
The big takeaway is that you are missing out on half a days worth of sunshine.
We added net metering to our system, took our provider almost 3 years to get it done and was lots of hoops to jump through but in the end well worth it, we have had zero billing for the past 8 months as the afternoon sun feeds into the grid after charging the batteries. Even with the recent storms and dark days living in the shadow of mount makiling we still have substantial credit with the electricity company.
If your installer is good net metering can be achieved quickly, we learned the hard way with a disreputable installer.
Good luck and keep up the videos.

Friends tell me that when Typhoon Odette hit about a year before I moved here, electricity was out for several weeks. Now, as long as a typhoon doesn't damage my solar panels, I could live entirely off solar indefinitely. We might have to be a little frugal with use of aircons, but that's about it.

Having this setup gave you comfort living tru the day. You can turn on the aircon for 24/7 with a lower monthly bill. <3

I have a  solar system in the Philippines  also. What help to preserve some of the battery energy were to buy all inverter type appliances.  The freezer, refrigerator, washing machine, inverter type a/c, microwaves. Even the electric fans with DC motors are a great help,and also all LED lighting for whole house. Those things will use much less energy wattage then the conventional type appliances from my experience. Keep up the good work in developing your Farm.

Another battery would most likely to have enough storage to go nearly 100% off grid

Add a few more panels to ensure 100% charge for the batteries.
Im no pro but the data may be interesting to see.

I went grid free in my house in Davao with a very small system for more than 3 years.  Change that aircon to an inverter type.  Switch to gas cooking.  Buy rechargeable Energy light bulbs Phillips has a good option, Also you can run and install 12 volt lighting if needed. But you have a full system and looks all like high quality work.  Great job on your 12kw to 16kw system.   update only recently had Davao light reconnected as I am away and need to do repairs and upgrades to our system.  Great Video.

Thankyou for this informative video. It is interesting to see your energy usage and how a Hybrid system still connected to the grid works best for you.

Glad to have seen this today, gives me a bit of an idea as to what I'll be needing when I get there

Wow exactly the setup I was planning.

We’ve had our system for just over a month. 20 panels, 12kW inverter and 1 x 16kWh battery. Our last electric bill was ₱900 although we weren’t aware we’d been on the grid at all. We run 1-2 aircons during the day and 1 at night. We usually have 30% charge left in the morning. We’re very happy with the system and will tweak things so we never use the grid

Thank you for the great info sir. Planning to have this also in my house in bicol. God bless you and your family❤

Just change that old aircon to an inverter they arent that expensive and you save a ton in electricity bill.

when you are on a budget and just want to get started with a limited amount of money, you can start without a battery an only a few panels and one grid-tied inverter. like 4 panels, to for the morning and two for the evening and one hoymiles inverter. if you do everything yourself you get back the money in about two or three years by lowering you electricity bill. of course there are a lot of factors for the ROI calculation.
after that you can think about upgrades. this way you can spread your investments over a few years and can start with this project with a small amount of money.

I appreciate your succinct knowledge and emxplanation.  Good job Sirb

A late friend of mine hooked up a large second hand fork lift battery to his solar system to take on the excess power need.

We only have a single battery and it works just fine through the night. Electric bill is  roughly no more than 300 pesos a month...IF that high; we've had it since May...maybe 5 months. Not only do we never notice brownouts other than to her neighbors' gensets popping on, but it also allows our appliances and devices more protection from the feared 'power surges' that can occur. Having solar also allows for uninterrupted internet access. Wife worries about the next big typhoon that might come through. Short of damage to the solar system itself (probably zero), prolonged rain could affect the collection capacity of our system but having a storm system simply hover over us for days on end and not being blown on past doesn't seem like an issue. WE love it.
