The vendor did a remote reboot of our system settings three days ago.  Since then we have pulled zero watts from the grid.  All of our power has come from panels and/or battery.  

That's a very good solar harvest for 5kw. I have only 3.3 PV array and 6kw (LiFePO 4 battery. How do you go on in cloudy conditions? I know they still pull some power even when it's cloudy and raining.

My panels are Canadian 550 watt panels x 6. But using grid power at night when the battery reaches its limit 30%.

Edit. Here' what  we produced and consumption. from 12 midnight til 9:39

But we have 5 adults living in the house at this time.

We have 10 550 watt panels and the battery is LiFePo4 and 20.24kwh.  Even in the cloudy weather it manages to easily charge the battery.  Left an AC running in the guest room last night as a test.  The battery was at 41 percent at 06:30.  At 10:11 it was already at 99 percent and it has been a mix of heavy clouds with occasional breaks to blue sky.   Below is a screenshot at midnight to 12:15pm today.

Sorry I you guys have addressed this in the last 3 pages of comments.......

My OFW BIL has just retired and is going to remodel his house. His contractor has mentioned solar panels. His questions are: How susceptible are they to typhoons nowadays? and what is the return on investment. How long until they pay for themselves approximately? We really do not worry brownouts to much here in Metro Manila. Thanks.

My panel have been thru two typhoons with no problem. It all depends on the mounting system but typically are rated at over 2400 Pascals wind resistance or 140 mph. Pay back? Depends but our net metering system will have paid for itself this year. I didn't really worry about the payback time . I wanted AC and other creature comforts without a ridiculous electric bill. I knew my Meralco meter without solar would go up each year and only be an increasing expense.

grid tie 2-3 years, off grid 4-5 years. Mine were fine during the last big typhoon here that took down about 10 of my mango trees.

We put the panels on the sloped roof that is facing away from the ocean.  That seems to be where we get our strong winds and salt spray.  I watch the installers and it looks to me to be strongly attached to the long span roofing.  The long span is attached to metal girders.  Now that we have solar we will add a circuit and have a 1.5 split inverter AC installed in the living room.  I can also run my pool filter longer each day which means less work for me when doing the pool vacuum. I expect the ROI to be 5-6 years, less if rates continue to increase.  We still brownouts in Moalboal on a fairly regular basis because they are still in the process of upgrading and replacing the backbone that runs from the Cebu City area south to the end of the island.

This was the system I had installed in March 2024 after my home in Cebu was built. The all-in price was P370,000. Since we didnt have any electric bills to compare the savings, I would guesstimate our electric bill would be in the 10k a month range. Our first full month electric bill was P450 our last one was P700 for the month. We run a 3hp inverter split AC during the hottest part of the day 12noon til 5pm. We run a 2hp in our bedroom all night.

I just looked at our KWH annual consumption for the past 3 years. It's works out to be an average of 22kwh/day. We feed back to the power company almost as much as we buy from them but of course they don't credit us with same rate. We get 50% less than they charge. That's Meralco, others pay less. Though the ERC mandates the electric providers pay you for your excess PV power they don't say how much. 50% is actually pretty good compared to other places.
