Basic information about solar water heating
Q: How do solar water heating systems work?
A: Solar water heating systems work very similar to solar electric systems, except they don't produce electricity. Solar water heating systems use solar panels to provide hot water for your home or business.
Q: Do I still have hot water when there is no sunlight?
A: Yes, solar water heating systems almost always require a backup system. This backup system is typically a conventional water heater.
Q: How long will my solar water heating system last?
A: Properly designed and installed solar water heating systems may last 20 years or longer. Most solar equipment retailers offer warranties ranging from five to 10 years. SRP recommends reviewing warranties with solar equipment retailers before selecting a particular system.
Q: Do solar energy systems require maintenance?
A: Solar electric and solar water heating systems are, for the most part, passive systems. However, to keep them working at optimal performance it is recommended to keep the panels clear of dust and debris - this can be accomplished by taking a hose and spraying down the panels. It is advisable to consult manufactures for further questions regarding maintenance of solar energy systems.
What are the benefits to having a solar energy system?
- Save money every month by lowering your electric bills.
- Utilize free energy from the sun to reduce the effect of utility cost increases.
- Enjoy energy independence by becoming your own power producer.
- Protect the environment by using clean, renewable energy in your home.
What other considerations should I know before purchasing a solar energy system?
Prior to installing a solar energy system, please take the following considerations into account:
- Solar technologies have high initial costs. Purchasing a solar water heating system is like paying
for your electric bills upfront.
- It is important to take into consideration the amount of solar variation when the sun is not shining during evening/nighttime hours or during cloudy weather conditions. Also, it is a good idea to look at your property. Do you notice any large trees or other obstructions that may cause shading on your solar panels?
- Depending on the mounting method, some systems may impact roof warranties and home
insurance policies.
- Homeowner association rules may affect system selection and mounting. It is advisable to review
these documents with your association before installing a system.
