Air-Conditioning Costs Comparison

Summer on the Spanish Costas means weeks of hot, sticky weather.

Due to the cost of air conditioning, most homeowners feel stuck with three options:

• Run the AC all day – and pay €100s extra in electricity costs
• Keep AC to a minimum – and suffer through fans, poor sleep, and heat exhaustion
• Abandon Spain entirely for the hottest weeks of the year

None of these is ideal.

That’s why Marblanc Solar clients are increasingly choosing solar panels to help them use their AC in summer, while paying peanuts for electricity.

But here’s a key point: most homes with solar have some monthly electric costs as AC units typically consume more power than the panels can produce.

So…what does cooling your home with AC + solar look like?

Using technical performance data, we’ve estimated the monthly electricity costs to cool a home to 22°C for 12 hours a day in August.

We’ve compared three different property sizes using three methods:

• Efficiency G air conditioning units
• Efficiency A air conditioning units
• Efficiency A air conditioning units + PV solar panels (no battery)
