Conclusion: solar is still a very good investment! Using everything on site gives a cost well below the average home's grid electricity cost of around 16p per kWh, and even further below a typical peak time-of-use tariff of 18p per kWh.. What's more the cost of grid electricity is rising.

Split System Costs The proof of that energy efficiency lies in the power bill pudding. Split systems typically use about 9,000 BTU or 900 watts. Running for eight hours per day at the national average kWh unit cost of 13.2 cents, a ductless mini-split would cost only 95 cents per day to run, or about $28.50 per month.
