Q. How are hot water requirements calculated and how is the solar water heater sized
|
|
A. The hot water requirements are calculated by taking into account the number of people living in the house and the size of the hot water cylinder. Each person living in the home is calculated at 50 litres per day, so that a 5 person home would need a cylinder of 250 litre capacity. The solar panel is then sized to heat the 250 litre cylinder, taking into account the average climate conditions and the orientation of the roof; south, south east or south west. Typically, a cylinder of this size will require 2.5 sq.m. of solar collector.

Q. Is the solar panel configured to the manufacturers specification
|
|
A. No, the manufacturer does not specify the size of collector needed for any given application, this is calculated by the design team in Systemlink taking into account size of house, number of people and orientation of the roof.
|
|
Q. What percentage of the hot water requirements will be covered by the solar panel
|
|
A. Up to 70% of the annual hot water requirements will be delivered free of charge
|
|
Q. Is the location of the solar panels (orientation, tilt, visual aspect) appropriate
|
|
A. Yes. The panel should be mounted at 40% (typical roof tilt) and be south, south east or south west facing. If the house has a flat roof a special moounting kit is provided to ensure the correct tilt. The panel is surface mounted.
|
|
Q. Is there any disruption of the building structure required to install the system
|
|
A. Minimal disruption is caused on the roof as the unit is fitted on the surface. One tile is lifted and replaced with a sealed weather proof rubber plate through which the manifold pipe is installed. A Dual coil cylinder is sited in the house unless the existing cylinder is used. This will require some pipe work. The entire installation takes aprox one day.

Q. How is back up heating provided
|
|
A. back up heating is provided by any other means such as gas or oil boiler, heat pump or wood pellet stove. The cylinder is fitted with an immersion heater for use when the boiler is not required.
|
|
Q. Is the system regulated to bring the hot water to 60 deg. at least once per day
|
|
A. Yes, if the external connditions are overcast the water in the cylinder will be automatically heated by the alternative heat source to the required temperature.
|
|
Equipment
|
|
|
Q. Are the solar panels and storage tank certified by a quality label and CE compliance label
|
|
A. Yes.
|
|
Q. Are all the flashing and fixing components for the solar panel provided
|
|
A. Yes
|
|
Q. Do all the materials used conform to the solar system manufacturers specifications
|
|
A. Yes
|
|
Q. Is the system protected against overheating, freezing and excessive pressure
|
|
A. Yes
|
|
Q. What is the performance rating of the solar collector under expected operating conditions
|
|
A. The solar panel The estimated annual energy yield in kW hours is 1,600 for a 20 tube panel and 2,000., for a 30 tube panel. The rated heat output is 2 kW.

Installation
|
|
|
Q. Do we offer delivery, installation, commissioning and after sales service
|
|
A. Systemlink do not install. Systemlink have an approved installer list of contractors who are trained to install and provide ongoing service, within your region.

Commissioning
|
|
|
Q.Who is responsible for commissioning
|
|
a. The Systemlink approved installer commissions the system, Systemlink will attend if required by the installer
|
|
Q. What are the procedures carried out when commissioning the system
|
A.
a) Set up controller
b) check that the water is flowing
c) check that the sensor at the manifold is reading the tempetrature of the water and is communication with the controller.
d) check that the sensor at the cylinder is measuring the temperature of the water in the cylinder
e) check that the pump will run when the temperature of the water in the manifold is higher than the cylinder.
f) check that the operating pressure is 1 bar
