🔋 Battery Backup Photovoltaic System (Hybrid Photovoltaic System): This system carries the electricity generated from solar panels in the rest of the house to be stored in the battery to be backed up during night or during power outages, so that electricity can also be used for designated equipment such as air conditioning, lighting, medical equipment, aquarium oxygen, Internet, or security systems. It is suitable for homes in frequent outage areas, homes that rely on medical equipment, or homes that need continuity of electricity.

But what to consider is that the system has a higher price than the average system because it has an estimated battery cost of 100,000-300,000 baht. The battery has an average life of about 10 years and may need to be replaced in the future, including having to design the system to suit the actual traffic, such as how many hours to reserve the light to choose the appropriate battery size.

⚡ solar system: During the day, the house will use solar lights first. If it produces more than it uses, the rest can be sent back into the electricity system for sale to the public sector on specified terms. It must first submit an application through the PPIM system of electricity. Electricity will be purchased for about 2.20 baht / unit, and the balance will be deducted from the power bill. The contract period is 10 years. You should check the latest policy and conditions before making a decision. It is suitable for homes that use a lot of electricity during the day. You want to reduce the power cost as much as possible and have a limited budget than the battery system.
