Energy generation

Photovoltaic modules - solar power!

Photovoltaic (PV) modules is the name for what many people call solar panels. Photovoltaics can generate electricity for your home or business, either as part of a stand-alone power system or for buildings already connected to the local power network.

Photovoltaic modules or solar panels have become more affordable over recent years. This, along with improvements in the performance of these products means they are a viable option for energy-aware, cost conscious home owners who want sustainable solutions.

During the day, your system will generate solar electricity from sunshine. Any excess solar electricity not immediately used in the home will be automatically fed back into the national electricity grid, giving you a credit against your power bill account.

For grid-connected solar systems, the electricity works just like the electricity supplied through the electricity grid providing you with 240V AC electricity.

How they work

Solar panels (typically on the roof) silently generate energy which is fed to an inverter which converts the energy into standard household electricity.

When the sun isn't shining or when your energy demands are greater than your solar system generates, you will draw electricity from the grid as your home normally does, so you have a back- up in place if you need it.

PV systems are:

• quiet
• non- polluting source of renewable energy
• reliable and robust
• have low operating and maintenance costs
• fairly unobtrusive

Invisible facade systems that generate power.

E-Architecture offer an innovative new product from the world leading Wurth Solar in Germany.

A new type of facade system, the product not only generates electricity but opens up new visual possibilities in facade design.

Würth Solar is the leading innovator in technology for generating photovoltaic energy has developed a new type of system with integration of its GeneCIS modules.   In a world-first, the ARTLine Invisible facade system includes the option of coloured CIS modules and innovative facade-mounted retaining system for rear-ventilated facades.

The modules are bonded to a support plate, which is hooked into a substructure. For the first time the entire substructure is completely concealed, which lends the whole facade a homogeneous and refined appearance.

Where are photovoltaics used

In New Zealand, PV systems are used to power communications equipment, water pumps, electric fences.  They have been used on farms, public buildings and petrol stations for some time.

Stand-alone PV systems are not connected to the electricity network.  They store electricity in batteries and are a cost effective solution for homes, farms and communication stations in remote areas.

Even some of the calculators that we use every day use PV systems.

Earn money from excess electricity

If your PV system is linked to the local power network, electricity can be supplied back to the network if it generates excess power.

You may be paid for the electricity exported to the network. 

You will need an agreement with your retailer, and requirements vary between network companies and retailers.
