Surprisingly even on cloudy days, it pulls about 900-1100 watts from the sun. The benefit from a more numerous panel set up is that not just the peak power produced during full sunlight but even during cloudy days you get more usable amounts produced.
1.5mwh would be about 20 recharges of a Tesla 85kwh model (there's a buffer of about 10kwh that never full discharges or charges). Considering I get 270 km in real world driving from a full charge/discharge, I could have travelled 5,400kms on that power with family and luggage lol
As for the power buy back, the wheels are creaking very slowly... I chased up with the installer the other day but still waiting for the inspection appointment. But hopefully within another few weeks. About the payment details, you have 2 options, to have credit going back to your CLP account. Or they will issue a check to the registered owner of the CLP account every month. I chose the cash option in case I leave HK and the buy back amount is over the actual consumed amount. With a 5kwh system I'm hoping even with full usage during the day there's some left over to fund my evening usages.
You said you are in CLP's area? then around 40% of your electricity is coming from nuclear, which means your carbon displacement is probably a lot lower than you thought.
On that note, an interesting story; I was browsing property online for backcountry Canada and saw a property agent surnamed Wong. She had an interesting listing and we end up talking on the phone about her transition from HK to Vancouver to Kelowna and then Horsefly BC over the course of 10 years. She and her husband and a 8 year old stayed on a 160 acre off-grid lot for 4 years. I was like wow how did your daughter take that transition and she said they had lots of books and solar set up. Husband was more busy tending to the 160 acres making sure the access roads are in good condition. But yea there is an alien part of the world/existence beyond what most people believe in Hong Kong =)

btw. regardless of whether from taobao or from elon musk, i don't think any rechargeable batteries based on current technology are going to last you 10 years.. look at the mobile phones. the good ones like apple or samsung.. after 3 years the battery get bloated and charge span reduced by half or more...
