Solar air conditioning, or "solar-powered air conditioning", refers to any air conditioning (cooling) system that uses solar power. This can be done through passive solar design, solar thermal energy conversion, and photovoltaic conversion (sunlight to electricity).
Alternatively, solar air conditioning systems can integrate photovoltaic (PV) technology to generate electricity for powering conventional electric air conditioning units. PV-powered systems are straightforward in design and can be installed as standalone units or integrated into existing HVAC systems with minimal modifications.
Solar air conditioning systems can be particularly beneficial for both residential homes and commercial buildings. For homeowners, installing a solar AC system can lead to long-term savings on electricity bills while reducing their carbon footprint.
A solar air conditioner combines solar electricity and air conditioning. In simple words, it takes energy from the Sun and uses it to power your AC to cool your space! A solar panel is a device that captures the power of the Sun. It converts the Sun rays into electrical energy. This energy can then be used directly or stored in a battery.

There are two ways to achieve solar power air conditioning. 1. If you outfit a home with a photovoltaic solar power system with enough capacity, it will supply plenty of power to run any air conditioner you choose – central AC, ductless AC, window AC, portable AC, etc. This is not what this article is about. 2.
Solar panels, usually photovoltaic panels (PV panels), collect sunlight in their cells. The panels turn the sun’s energy into electric power. This is DC power, and if you choose a DC air conditioner, the panels can be wired directly to it. Most AC’s are AC power – that’s confusing. Most air conditioners require alternating current power.
Essentially, solar air conditioners can be divided into two categories: In a whole-home system, an array of photovoltaic (PV) solar panels will generate the electricity used as a power source to run the air conditioning and other appliances.
Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to 2022.
These benchmarks help measure progress toward goals for reducing solar electricity costs and guide SETO research and development programs. Read more to find out how these cost benchmarks are modeled and download the data and cost modeling program below.
The cost of utility-scale solar in 2022 was down 84% from 2010. Solar power purchase agreements in the West were an average of $10/MWh lower than in other regions. Larger utility-scale solar projects (20 MW+) cost 26% less per MW than projects between 5-20 MW. Annual Energy Outlook, 2023.
Projected change in price by fuel type, 2022-2050 Solar, wind, and hydropower are based on the projected levelized cost of energy, which includes capital expenditures and operating costs, while natural gas, coal, and nuclear are based on the projected cost of only the heat content of these plants.
