Solar electric systems (photovoltaics):
Solar electric systems have been around for many years and are installed on hundreds of thousands of roofs globally with their benefits well documented.
They are also well proven in New Zealand.
Steadily increasing electricity prices are leading to a growing number of installations as people realise the many dollars they can save.
The solar electric systems are quickly installed ( by experienced installers) and once installed are virtually ‘plug and save’.
There are three important provisos:
Getting the design right from the start is essential.
There are several considerations – the most important are:
• Your budget
Determines the best fit solution and the expected savings
• The amount of electricity you use or are likely to use
Determines the best size for a solar electric system
• Your location
Determines the yearly amount of sunshine you are likely to get and thus the amount of convertible energy
• The size of usable roof area (or other options)
Determines the maximum size installation possible
At a more technical level, the mounting of the solar electric modules should be generally north facing, unshaded and at a minimum slope of 10 deg for the solar electric modules.
It is usually possible to design/engineer around any issues that may arise regarding these technical conditions.
The above considerations are the reason why it is important to have your property assessed for both its suitability and for an accurate estimate of cost and benefits. Our experienced team is happy to provide this service on your request.
