Yes.<\/strong> It is one of the best uses for solar panels. Air conditioning uses the most electricity during the sunniest hours, and that is exactly when the panels produce the most. With a well-sized installation, you can use the air conditioning all summer and barely notice it on your bill.<\/p>\n

We explain how much an air conditioner uses, how many panels you need and how much one of our clients pays in September.<\/p>\n

How much electricity an air conditioner uses<\/h2>\n

A 3,000-frigorie inverter split unit (for a living room or a large bedroom) uses around 1 kWh for every hour it is on<\/strong>. The exact figure depends on the unit, the home’s insulation and the temperature you set.<\/p>\n

Here is a typical example on the Costa del Sol or in Murcia:<\/p>\n\n\n\n\n\n\n\n
Use<\/th>\nConsumption<\/th>\n<\/tr>\n<\/thead>\n
1 split unit, 8 hours a day<\/td>\nabout 8 kWh\/day<\/td>\n<\/tr>\n
2 split units, 8 hours a day<\/td>\nabout 16 kWh\/day<\/td>\n<\/tr>\n
2 split units for a month<\/td>\nabout 480 kWh<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

With electricity at \u20ac0.21-0.30 per kWh (PVPC prices for September 2026, according to FACUA<\/a>), the air conditioning alone can add more than \u20ac100 a month<\/strong>. Add the fridge, cooker, washing machine and hot water, and it is easy to reach \u20ac150-200 in a home with air conditioning<\/strong>.<\/p>\n

Why solar panels and air conditioning work so well together<\/h2>\n

They coincide in time.<\/strong> The heat is at its peak between 13:00 and 19:00. During those hours the panels are at their best.<\/p>\n

They produce more in summer.<\/strong> In the province of M\u00e1laga, each installed kWp produces around 1,650 kWh a year, according to PVGIS (European Commission)<\/a>. On a summer day, that is about 6-7 kWh per kWp.<\/p>\n

Selling surplus energy at midday barely pays.<\/strong> You get paid almost nothing for the energy left over at those hours. On 16 September 2026, at 15:00, surplus compensation was \u20ac0\/kWh<\/strong> (data from Red El\u00e9ctrica<\/a>). If your air conditioning uses that energy, each kWh you don’t buy from the grid is worth \u20ac0.21-0.30, not \u20ac0.<\/p>\n

In short: every kWh the air conditioning uses while the sun is shining is a kWh you don’t buy.<\/p>\n

How many panels do I need for air conditioning?<\/h2>\n
