Green Collar Careers - System
Installation
Once materials are on site solar heating systems installation take
the following actions, not necessarily in this order:
- Mounting of the solar collectors (and Solar PV panel if
equipped)
- Aligning the solar collectors to the elevation and azimuth
(usually Solar Noon of the Spring/Fall Equinox)
- Removing existing water heater (90% of the time, 10% may
maintain their existing heaters)
- Disposal of the existing water heater (most installers should
take care of this)
- Installing and connecting the storage tank to the house water
system
- Installing and connecting the water heater to the house water
system
- Connecting the AC to the water heater, and replacing the circuit
breaker at the power panel - Optional
- Routing the plumbing for the Closed Loop system between the
solar collector and the storage tank
- Installing the pump, valves, gauges, and expansion tank
- Pressure testing the Closed Loop system (usually with air and
waiting about an hour for pressure drop)
- Mounting, connecting, and testing controller
- Fill system with antifreeze
- Insulating Closed Loop plumbing
- System test and commissioning
- Final inspection
Typically two installers are required for a system with an 80
gallon tank, 3-4 installers may be required for a 120 gallon tank.
Labor hours from one installation crew and system installation site
will vary between about 16 - 40 hours. With an experienced two
person crew most systems can be installed in the same day although the
crew will have installed 3-5 systems before reaching that efficiency
level. Installation crew supervision is a must - at all times
they have access to the inside of the home, lunchtime included.
Plus you can lend a hand at times where an extra person will shorten
the installation time. As tempting as it may be to eventually hire
your own employees for installation, you'll almost always be better
off using contracted installers. That doesn't prevent you from
training your own crew and pay them via 1099. See the
IRS Independent Contractor Definitions to understand the federal
government position on this. As an independent contractor they
will have higher hourly rates with no other costs, less liability to
you, and they will have the freedom to work other jobs. For the
homeowner, installers will have access to their home and will need
to be very trustworthy individuals with good morals and ethics.
They need to be responsible, preferably with a clean shaven
professionally dressed appearance. That doesn't mean business
informal; that means work boots, clean clothing, and the less
exposure of tattoos the better. Some people just don't trust
others based on a sloppy appearance to enter their homes. System
installation is a major inconvenience to the home owner. You
should insist they be home during the installation, even if it means
a weekend installation. That will discourage any subsequent
disputes after the job is done. The homeowner will be without
water during the installation. If the job cannot be finished
in one day be sure to make plans for reconnecting the home water
system before leaving for the day. This is another great
reason for a dual purpose tank - an experienced installation crew
can swap out the hot water heater with a Solaraid HE and have the
home water restored in as little as two hours. The ideal crew
consists of:
- One Jr level plumber with basic electrical wiring skills
- One entry level plumber
- General laborer with limited carpentry skills and a strong
back
