Why solar air conditioner
As a renewable energy source, solar photovoltaic generation is an excellent solution for saving energy bills in areas with abundant sunshine. Using solar energy to operate air conditioning systems is a practical and economical alternative to conventional electricity.
There are two types of solar air conditioners: one is AC/DC hybrid solar air conditioner, and the other is full DC solar air conditioner.
AC-DC hybrid solar air conditioner
Solar air conditioners are capable of drawing power directly from solar panels. Solar panels capture sunlight and convert it into direct current (DC). This generated electricity is used to power the solar air conditioner unit. The number of solar panels required depends on the power rating and capacity of the solar air conditioner.
The AC-DC hybrid solar air conditioner has three working modes: one is powered by solar photovoltaic power generation, the second is powered by public grid AC power, and the third is powered by both public grid AC power and solar photovoltaic power generation.
The solar air conditioner's built-in intelligent energy system executes seamless switching of power sources under the logic of maximizing the use of solar photovoltaic power generation.
Full DC solar air conditioner
A fully DC solar air conditioner uses direct current (DC) power and cannot operate with alternating current (AC). Solar photovoltaic power is regulated using maximum power point tracking (MPPT) technology to power the solar air conditioner. Solar charger stores excess PV power in a battery for future use. At night or when sunlight is low, the solar air conditioner uses power from battery.
Full DC solar air conditioner has three working modes: one is powered by online solar photovoltaic power generation, the second is powered by DC from battery, and the third is powered by both DC power from battery and online solar photovoltaic power generation.

Solar air conditioner sizing
BTU, tons, HP, and kW are different units of measurement for an air conditioner's cooling capacity. Most people use BTU and tons to express an air conditioner's cooling capacity, while some prefer HP and kW.
12,000 BTU = 1 Ton
1 ton ≈ 3.516 kW
1 hp ≈ 0.7457 kW
1 kW ≈ 3,412 BTU/hr
