I believe many forget that some people build a system not only to save money, but also for reliability, comfort, and more control over their own power. It means you can use more electricity than you normally would, as long as the batteries keep charging. Nobody here pays 7 baht per kWh? Well, some do. We live outside the normal PEA limits, about 300 meters from the last PEA post, and we have a 30/100 amp meter. Because of that, we are on temporary/construction-style electricity, around 6.8 baht per kWh before Ft and VAT, so in reality it is over 7 baht all-in. On top of that, we also had poor and uneven voltage. With our setup, we can actually produce up to 18 kWh during peak time, even with a 10 kW inverter. That gives us a lot of flexibility when the sun is strong and the batteries are taking charge. Last month was higher than normal too, since we also have ongoing construction. Now we can also use a proper welding machine on our land without voltage problems, which will be useful for my workshop later on. It is also about having a reliable system that protects the house equipment and gives us future possibilities too, like adding an EV next. We also see the need for being more self-dependent in the future, especially after how the world situation has escalated. Last month usage
