If you currently do not heat your pool, a solar heating system can provide an economical way to extend your pool season, starting earlier in the spring and extending later into the fall. Compared to conventional pool heaters using propane or natural gas, solar pool heating systems can pay for themselves in six years or less. Solar heaters are often the most economical way to heat a swimming pool. In the event of extended cloudy days or low solar resource a back-up generator is recommended to be incorporated in order to guarantee power. As a result Standalone systems require special inverters and other additional equipment. Standalone systems typically generate electricity at a lower DC voltage in order to provide a more appropriate match to battery voltages. Standalone systems have different design considerations than grid-tied systems. Remote telecommunications and signaling systems.Computer Universal Power Supply (UPS) and server backup systems.Commercial, Agricultural, or Residential energy users that can not afford to be without power or have critical loads.Structures for which it is too expensive or too far to run utility power.Remote Cabins, Residences or Houseboats with no other convenient source of power.The following are some excellent applications for standalone solar systems: Standalone systems are highly desirable in situations in which the utility grid is non-existent, unreliable, or too costly to connect due to distance. Typically the energy generated is stored in large battery banks giving standalone systems the ability to be completely independent of grid power. Standalone or backup systems differ from grid-tied systems in that standalone systems are designed to store the energy they generate to be used at a later time. utilities are required to purchase/credit the excess electricity generated by small power producers at regular retail rates. ![]() Under the Public Utilities Regulatory Policy Act of 1978 (PURPA) and related legislation, U.S. You will purchase power from the utility provider at (off peak) lower rates during the evening when your PV system is not generating power. TOU billing offered by the utility company will credit power supplied from you at peak rates during the day when your system is generating more power than you consume. Grid-tied systems are often combined with a time-of-use (TOU) rate schedule from the electric utility company. ![]() During dark hours or extended cloudy days the PV system is off line so your electrical needs are supplied by the utility grid. You pay only for your “net” usage of electricity from the utility company, so if your PV system generates more electricity than you can use your electrical meter will actually run backwards! The excess energy is credited back to your account by the utility provider (PG&E, SCE, or SDG&E) and is transmitted back into the utility grid. Grid-tied systems make use of net metering, meaning that the energy that is generated by your solar PV system is used to offset the electrical power that you require for your loads (appliances, etc.) from your utility company during the day. The beauty of these systems is the electrical “grid” of your utility company serves as a giant rechargeable battery bank. These systems use the power of the sun to generate electricity and immediately deploy that energy into your loads (appliances, etc).
