    The U.S. Department of Energy provides a complete breakdown of the basics of solar hot water heater systems. As they explain, there are basically two types of solar hot water heaters: active systems, which contain circulating pumps and controls, or the passive systems, which don’t. Both of these plans will require solar panel collectors and storage tanks for the water.

    The solar storage tanks will need to be well-insulated to lock in the heat and keep out the cold. You could opt for a two-tank storage, where your system would preheat the water before it enters your conventional water heater. Or you could decide on the single-tank storage option, which combines the back-up heater with solar storage within the same tank.

    1. Pre-install questions to answer;

    Do you have a south-facing area of roof or land that can accommodate your solar system?

    A south facing roof will provide the optimum potential for your system. However, depending on your building orientation, other directions can also provide sufficient production.

    Do you have any daytime shading issues on your south-facing space?

    Shading by trees, buildings, etc. will have a negative impact on a PV system’s performance, if the shading issues cannot be solved, perhaps your property is not a good choice for solar. Poncho's can help you determine the impact of shading with a site visit.

    Will you need to repair or replace your roof in the next 2 years?

    No Problem. If Poncho's installed the system, we will remove and replace the system free of charge.

    2. Site Visit

    Poncho's will arrange with you to come out to your home or business and determine the best possible solution for you solar requirements. Poncho's solar engineer will determine;

    Direction of the roof, type of roof, roof condition, and angle of the roof in order to best determine the solar panel requirements

    Measure the roof surface to determine the square footage available for placing solar panels or solar hot water heating collectors

    Determine if roof, or ground mounted systems would be best for the situation

    Draw a plan of the roof or ground area to review with the best possible placement

    Discuss the plan with you and determine the next steps

    3. Installation

    Prior to installation Poncho's will have submitted to the County and have obtained all the required permits, permissions and authorization (such as compliance with community CCR's) in order to proceed.

    Remove the old water heater and dispose of it

    Install a 110v GFI outlet and 220v quick disconnect.

    Install roof supports, the correct type for the roof type, to place the solar hot water collectors on

    Install the solar hot water collectors on the roof supports

    Install the new hot water heater

    Create and connect the new piping for the intake and output of the water to the new water heater

    Weatherize and insulate all pipes and connections

    Test and tune the new hot water system

    Explain and demonstrate how to use the new solar hot water system

    Clean up and leave you smiling with your new solar hot water heating system!!

    i think the above answers have analized in different aspects. First, solar energy is transferred to thermal energy stored in water/anti-freeze inside solar collectors; Second, thermal energy in water/anti-freeze is being exchanged to thermal energy in water inside water tank. www.himinsun.com
