1. Research and Development High-efficiency solar panels often incorporate cutting-edge technology, which can drive up production costs. Manufacturers investing in solar cell innovation strive to improve efficiency and lifespan, which is reflected in the pricing.
2. Scalability When starting with a smaller off-grid setup, a 3kW inverter provides flexibility for future expansion. Users can begin with a modest number of solar panels and gradually increase their capacity as their energy needs grow. This scalability makes it an attractive option for those who are just entering the renewable energy market.
