Installation Process - Solar Water Heating

Poncho's Solar Services is always available to discuss your solar questions or requirements. Stop by one of our offices or see us at our booths at the local farmer's markets or arts and crafts shows. For the installation process for solar water heating, please review the following:

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!!

Types of Solar Electric Systems

ponchos logo

A solar electric system is typically made up of solar panels, an inverter, a battery, a charge controller, wiring, and support structure. The three most common types of solar electric systems are grid-connected, grid-connected with battery backup, and off-grid or stand-alone. Each has distinct applications and components.

Grid-Connected -

This is the most widely applied in Hawaii. The solar panels are connected to your local utility electrical grid to complement your normal power supply from your utility company. Grid-connected systems consist of:

  • Solar panels mounted on the roof
  • An AC converter to convert electricity produced by the system from direct current (DC) energy into alternating current (AC) energy.
  • A junction box that extends from the solar panel wiring to the AC disconnect and then the breaker panel on the home.
  • A power meter that displays how much power the home  produces and used, the meter is owned by the local utility company.

Grid-Connected with Battery Backup -

Very similar to the grid connected system, this system adds a 'battery bank' to collect the power generated from the solar panels. Power stored in the batteries can be used during power outages. The battery bank collects power produced by the solar panels, sends it to the breaker box, and then into the house power system. The components of this type system consist of:

  • Solar panels mounted on the roof
  • An AC converter to convert electricity produced by the system from direct current (DC) energy into alternating current (AC) energy.
  • A battery bank for power storage
  • A charge controller to prevent overcharging the batteries
  • A junction box that extends from the solar panel wiring to the AC disconnect and then the breaker panel on the home.
  • A power meter that displays how much power the home  produces and used, the meter is owned by the local utility company.

Off-Grid or Stand-alone -

These systems are not tied to any utility power lines and are most common in remote areas where connecting to the utility grid is more expensive then purchasing an off-grid system. In off-grid systems the solar electric represents the homes main source of power. Batteries store unused energy for use at night. Generators, small wind systems, and other backup fuel sources are sometimes used as backup power when the solar power stored in the batteries is not enough to meet household needs. The components of this type system consist of:

  • Solar panels mounted on the roof
  • An AC converter to convert electricity produced by the system from direct current (DC) energy into alternating current (AC) energy.
  • A rectifier, sometimes used to change AC to DC and back again to get the most use out of a system.
  • A battery bank for power storage

 

 

   

Types of Solar Cells

Mono-Crystalline versus Poly-Crystalline Cells

Mono-crystalline

Oor single-crystalline, cells are grown from a single silicon wafer. They are the most efficient type of PV cell. Because of the way they are grown, mono-crystalline cells are rounded. An early industry innovation was to trim the cell sides to pack more cells closer together in modules.

Multi-crystalline

Or poly-crystalline, cells are made up of variously oriented, small individual crystals that have been cast in a block. They range in color from bright blue to black. With their shape and crystalline structure, the multi-crystalline cells with small crystals resemble dark granite counter tops. Cells made with larger crystals resemble the structure if oriented strand board, but are glossier. Multi-crystalline cells are rectangular and closely butted into modules. Their larger surface area and denser packaging make up for the small difference in efficiency between multi-crystalline and mono-crystalline cells, leaving them essentially equivalent in generating efficiency.

Solar panels used to power homes and businesses are typically made from solar cells combined into modules that hold about 40 cells. A  typical home made from solar cells combined into modules that hold about 40 cells. A typical home will use about 10 to 40 solar panels to power the home. The panels are mounted facing toward the South in the Hawaiian Island, or they can be mounted on a tracking devise that follows the sun, allowing them to capture the most sunlight. Many solar panels combined together create one system called a solar array. For large electric or industrial applications, hundreds of solar arrays are interconnected to form a large utility scale PV system. Traditional solar cells are made from silicon, are usually flat-plate, and are generally the most efficient.

Solar Voltaic Technology

Solar Voltaic Technology

Solar cells, also called photovoltaic cells or PV cells, convert sunlight directly into electricty. PV gets it name from the provess of converting light, photons, to electricity, voltage and current, which is called the PV effect. The PV effect was discovered in 1954 when scientists at Bell Telephone discovered that silicon, an element found in sand, created an electric charge when exposed to sunlight. Today, worldwide, people power their homes and businesses with individual solar PV systems.
