Discover the best solar panel system for your home

Here at Robbie McDonald Electrical, we offer three solar system packages for your home or small business, each offering a different power output. Wattages range from 6,600 to over 15,000!

Our solar electric systems only use Tier 1 solar panels, the highest quality available. Tier rankings refer to the quality of panel manufacturers, and there are 3 types:

Tier 3, the lowest quality, represents more than 90 per cent of the new solar PV industry. These manufacturers do not invest in R&D and only assemble panels; they don’t manufacture silicon cells. They may also use manual soldering and other primitive production techniques instead of more accurate advanced robotics.

Tier 2 solar panels are slightly better and represent around 8 per cent of the total market. They make more use of robotics but can still rely on human labour. Most outfits have been producing panels for three to five years and are often small-scale.

Tier 1 panels are from the top two per cent of solar manufacturers. These are vertically integrated, meaning they don’t just assemble the panels. Instead, they manufacture them from the ground up, controlling silicon cell production and all the other processes required to produce a finished product.

Manufacturers in this category also invest in research and development. They try to push the boundaries of solar PV technology by increasing efficiency or developing new materials. They use highly automated robotic processes and have at least five years of experience making solar panels.

Tier 1 panels are the only panels we install on your property or premises.

How Solar Panels Work

Solar panels are a remarkable technology representing a potential solution to global energy concerns. They work by turning electromagnetic radiation from the sun into electricity.

The process starts when sunlight hits the panels’ photovoltaic (PV) cells. Beams travel through the glass casing and protective film to the active components of the unit.

Silicon cells then take this energy and convert it into electricity. They do this by generating an electric field via a positive and negative charge. Incoming sunlight hits the cells, energising them, and stripping their atoms of electrons. Loose electrons then start moving because of the wafer’s electric field, creating a current.

The energy then travels to the solar panel’s converter, transforming the direct current (DC) into an alternating current (AC) at high efficiency. You can then use this energy to power your home.

Frequently Asked Questions

Although it varies, solar panels usually last between 25-30 years, though this life span can increase and reduce depending on the make and model of the panel.

The amount you can save with a solar panel depends on how much sun a solar panel is exposed to, and how much energy a home or business typically uses. Properties with high energy bills can expect to save on average $10,000, over a 20-year period.

Check the inverter to make sure it’s not at fault. If you cannot see a red light, please call Robbie McDonald Electrical and we will come and inspect your solar system.
