The Installation Process
- PV systems are typically mounted to a racking system facing as south as possible. South facing panels insure optimum electricity production in the north hemisphere.
- On a angled roof the racking system is mounted onto the roof.
- On a flat roof the racks are not mounted, but weighed down.
- Metallic coated wires are connected to transport the electricity generated by the panels to the inverter.
- The installer will then find a shaded area to mount the inverter to avoid overheating. The solar inverter changes the electricity created by the system into a more compatible format.
- A DC disconnect switch and utility meter will typically be close to the inverter.
- The output of the inverter and the solar system will be connected to the circuit breaker box.
- The house or building will draw electricity from the circuit breaker box.
- Any electricity not used by the residence or building will be sent to the local grid.
- Like PV systems, solar thermal systems mounted to face as south as possible.
- Pipes will be installed to transport the heated fluid from the solar collectors to the hot water storage tank.
- The hot water storage tank will typically be installed next to the hot water heater.
- Some building and homeowners may choose to replace their hot water heater with a tankless wall mounted system. This allows for installation of the hot water storage tank in the location of the old water heater.
- Safety features are installed into the system, these include an anti scald valve which mixes cold water into hot water, pressure and temperature release valves, and thermal expansion tanks.
