The cost of a solar power system depends on several factors, including the system size, quality of solar panels, additional equipment like inverters and batteries, and installation costs. Generally, the cost of a solar system can be divided as follows:
Solar Panel Cost:
The price of solar panels is typically calculated per watt (Watt). Currently, the average price of solar panels is around 10-20 THB per watt, depending on the type and efficiency of the panels.
Inverter Cost:
The inverter is an important component that converts direct current (DC) from the solar panels to alternating current (AC). The cost of an inverter for a typical residential system ranges from 30,000 to 100,000 THB, depending on size and quality.
Battery Cost (if applicable):
If you wish to store energy in batteries, the cost will increase. Generally, lithium-ion batteries cost around 100,000 to 300,000 THB for residential systems.
Installation Cost:
The installation cost for a solar power system is usually around 20,000 to 50,000 THB or about 10-20% of the total price, depending on the complexity of installation.
System Size:
The cost of a solar system varies depending on its size. For example, a 5-kilowatt (kW) system for residential use may cost approximately 150,000 to 200,000 THB.
Estimated Total Costs:
For a small solar system (1-3 kW), the total cost is approximately 60,000 to 150,000 THB.
For a medium-sized system (5-10 kW), the cost is around 150,000 to 300,000 THB.
For a large system (over 10 kW), the cost may exceed 300,000 THB, depending on the size and components of the system.
The cost of a solar power system is an estimate and may change depending on various factors such as market prices, labor costs, and promotions from suppliers.
