Here are a few things you should know if you are considering a solar water heater in Maryland…

1. Cloudy days are fine for solar water heaters in Maryland. Solar water heaters convert light into heat and do not need direct sunshine.

2. Your Maryland solar water heater should be sized to store more  many day’s worth of hot water. With a solar water heater you are no longer wasting money and energy to store water…store as much as you can.

3. Don’t spend too much time worrying about the efficiency level of your solar water heater panels. Solar water heaters are not the same as solar PV panels (used for electricity). The energy you will be using to heat your water is free and can be stored. Spend more time making sure you have a properly designed/sized solar water heater storage system.
