The cost of a solar water heater can vary widely depending on the type, size and installation requirements. On average, you can expect to pay between $2,000 and $5,000 for the system, with installation costs adding $1,000 to $3,000.
On average, if you install a solar water heater, your water heating bills should drop 50%–80%. Also, because the sun is free, you're protected from future fuel shortages and price hikes. If you're building a new home or refinancing, the economics are even more attractive.
Solar water heaters have a long lifespan if they're properly taken care of. Depending on the quality of your solar water heater, it could last anywhere from 10 to 25 years. That's a lot of hot showers!

The solar water heater can heat the water up to 180 to 200 degrees Fahrenheit. The mixing station can mix the water to bring it to a safe temperature to use. The water that we use in our house in our faucet and shower is typically around 120 to 125 degrees Fahrenheit.
Check for any signs of damage, leaks, or corrosion. Inspect the pipes, connections, valves, and collectors for any issues. Cleaning the collectors: Keep the solar collectors clean and free from debris, dust, or leaves. Dirty collectors can reduce the efficiency of the system.
How Many Solar Panels Does It Need to Run a Heater? On the average house, you will need to install three standard-size solar panels to power a heater that consumes 1500-watts of energy per hour.
Typically, manufacturers guarantee 90 percent of panel manufacturing for the first ten years. After ten years, the percentage reduces to around 80% for the next 15 to 20 years. Your panels can continue to generate electricity after the system has reached the end of its useful life.
Solar water heater disadvantages
Higher upfront costs than most conventional water heating systems. Almost always must be supplemented with grid energy or a backup power source.
Active Solar Water Heating Systems
They work well in climates where it rarely freezes. Pumps circulate a non-freezing, heat-transfer fluid through the collectors and a heat exchanger. This heats the water that then flows into the home. They are popular in climates prone to freezing temperatures.
Relatively low renewable system cost: With an average price range of £3,000 to £7,000, solar thermal systems have a relatively low upfront cost compared to other renewable systems. For comparison, air source heat pump costs range between £5,000 – £18,000 and a solar PV system ranges between £2,500 – £10,500.
What is the average solar panel monthly cost? The average monthly cost of solar panels depends on factors such as system size, energy consumption, and financing options. However, homeowners can typically expect to pay between $100 to $200 per month on solar panel financing or lease payments.
The most popular Aussie made brand, Solahart, sized for a family of 4/5 will cost you around $4,000 fully installed. These cost from $6,000 upwards, fully installed.
A properly installed and maintained solar water heater can have a lifespan of about 20 years. This is a rather substantial advantage when you consider that a gas-powered model might last as few as eight years.

It is ideal for camping and can charge laptops, cameras, electric grills, kettles, coffee makers, and more.
Solar systems designed to provide central heating aim to replace 40 to 80 percent of conventional heating. They're most cost effective when providing 50 percent of the home's heat [source: NC Solar Center, U.S. Department of Energy].
There could be several reasons why your solar water heater is not heating. Some of the most common causes include lack of sunlight, a malfunctioning solar collector, a faulty temperature sensor, or a malfunctioning pump.
Do solar panels work at night? The answer is no, they don't. As we mentioned earlier, solar panels need light — preferably sunlight — to create energy. Although they can generate some energy from other light sources such as street lights and even the moon, the output is very low.
If there are trees near your home that create excessive shade on your roof, rooftop panels may not be the most ideal option. The size, shape, and slope of your roof are also important factors to consider.
The most common estimate of the average payback period for solar panels is six to ten years. This is a pretty wide range because there are many factors that will influence the number of years it can take to pay off your panels and the monthly savings you can expect.
Most homes will find that the savings from solar panels will outweigh the costs, although it may take anywhere from a few years to decades to achieve. Solar systems are costly to install but require little maintenance over a lifespan of 20 to 30 years.
