Thailand has a natural resource base and abundant sunlight resources. The average daily sunshine amount is about 5-6.5 kWh per square meter. In terms of photovoltaic development, it is also the oldest among ASEAN countries. As of 2017, the cumulative installed capacity reached 2,697MW. The current policy goal is to reach 6,000MW of installed capacity by 2036. At present, most solar power generation systems in Thailand are grid-connected solar power generation systems, and a few places use off-grid solar power generation systems. So how do I determine which residential solar panels is right for me?
This question was also asked by Daniel from Chiang Mai, Thailand. Maggie, an engineer with five years of solar sales experience at Mars Solar, explained that if the city power in your area is stable and the national policy allows solar energy to be connected to the city power, then a grid-connected residential solar panels is appropriate. During the day, solar panels provide you with free power, and the excess electricity is sold to the grid. It is also possible to obtain government subsidies to use city electricity at night. But if you are in an area where there is no utility power or there are frequent power outages, then a grid-connected residential solar panels is not a good choice. Because when the utility power is stopped, the grid-connected residential solar panels will also stop working and cannot provide you with electricity. Therefore, it is necessary to choose an off-grid residential solar panels. When there is the sun, store these solar energy in the battery, so that there is solar energy available for use at night or on a cloudy day. Some customers feel that batteries are expensive and do not want to buy them. This is unrealistic. Solar energy is an unstable energy source. Even in the same area, the energy density of solar energy is different. Sometimes it is strong, sometimes it is weak. When the solar energy is strong, the solar panel may be able to generate enough electricity, but the sunlight is weak. At that time, solar panels may not be able to generate enough electricity. Such an unstable power supply is meaningless.

Daniel lives on a farm in Chiang Mai, far away from the city, and the city is inconvenient. He usually uses diesel generators. Therefore, the engineers of Mars Solar recommended an 8KW residential solar panels for Daniel. This 8KW complete solar system powers his farm’s water pumps and his household appliances. Under the guidance of engineers from Mars Solar, Daniel, who has knowledge of electricians, installed this complete solar system. Does your farm also need such a stable and durable complete solar system?
