I've calculated my daily usage for April at 14kW, factoring in one air conditioner, two fridges, and LED lighting. My plan involves installing 7 Era panels, each with a capacity of 450 watts, along with a Sofar inverter, giving a total output of 3.3kW.
I won't initially include a battery and will depend on the grid for nighttime power.
The combined cost for the panels and inverter is 30,000 baht (purchased from Lazada), with additional expenses for cables and fixtures totaling 40,000 baht. Since my neighbor constructed my roof, I believe they can assist with panel installation.
I also intend to hire an electrician for mounting fuses and breakers, with an estimated cost of 6,000 baht inclusive of equipment. This brings the total anticipated expense to 50,000 baht, a significant saving compared to the initial estimate of 140,000 baht.
Considering potential future upgrades, I may integrate a 5kW battery into the system. Do you think this addition would be feasible given my current setup?
What are your thoughts on this plan?
