Introduction
Solar hot water systems should be designed and sized correctly before commencing
the installation. Proper design will ensure that a system is correctly sized to provide
many years of optimised performance and most or all of the required hot water when
the most solar radiation is available. However a supplementary heating system such
as oil or gas boiler, heat pump or wood boiler is required for months which have less
solar radiation. This guide will illustrate and explain how a system should be installed
to conform to the Joule manufacturer guidelines for the Acapella product models. Us-
ing this guide Stages of a solar installation are described in the following pages, with
illustrations where necessary to explain how to install the relevant components, and
contains general recommendations and important safety information.

To determine the total load on the roof you must get the total weight of the collectors and divide this weight
bythenumberofroofxingboltsoranchorsusedtoholdthecollectorontheroof.Thiswillgiveyouthe
weight of the solar panels on each point of the roof. You must then carefully review the points where the col-
lectorsareconnectedtotherooftoensurethattheseexactpointscantaketheanticipatedload.

The using this new weight examine the roof structure to ensure its suitability. You do not need to consider
the snow load when installing evacuated tubes.
EectsofWindLoad
The evacuated tube collector is exempt from consideration of wind loading for the same reason as the snow loading.
