We've had the solar hot water for 9 months. We also got a new higher SEER heat pump in April. We are definitely using less electricity, Whether this is because of the solar hot water or the heat pump is uncertain.
In 2014, we used 9973 kwh.
In 2015, we used 8858 kwh.
Costs in 2014 were $1141.
Costs in 2015 were $955.
Savings per year: $186.
