Solar Water Heater Cost and Energy Efficiency

This entry was posted in Solar Services on by .

Did you know that solar water heaters are more energy efficient than electric or gas water heaters? Powered by the sun’s energy, solar water heaters reduce reliance on the national power grid, while being resistant to electricity price increases and power shortages. In fact, they’ll pump out high volumes of hot water whenever you need it. Let’s take a look at the details to see why solar water heaters may be right for your family.

Why a Solar Water Heater?

The beauty of solar water heaters is their use of dedicated rooftop solar collectors to draw environmentally-friendly, clean, free power from the sun to provide hot water for your family. Solar water heaters are virtually maintenance-free and Valley of the Sun residents can reap some of the greatest cost saving advantages because it’s sunny over 300 days of the year.

What’s Energy Efficiency?

Deciding if a solar water heater is right for your household is based on the solar energy factor (SEF) and solar fraction (SF). Without getting too complicated, the SEF is the amount of energy delivered by the solar water heater divided by the energy put into the system, whether it’s gas or electric. In short, the higher the number, the more energy efficient the solar water heater is. For solar fraction, the important figure to know is the higher the SF, the greater amount of solar energy being used to heat water for your home.

Solar water heating systems list both the SEF and SF efficiency numbers plus how much heat (kWh) the system will deliver daily depending on hours of sunlight and daytime temperatures.

What Are the Costs?

The other primary factor to consider when deciding to go with a solar water heater is cost. According to, on average installing a solar water heater will decrease your water heating bills by 50% to 80%. To help you in figuring out what solar water heater is right for you, you’ll need to know the amount of hot water you use, available financing, rebates, tax incentives, system size, installation, and maintenance costs.
