Solar Panels: The Role of Photovoltaics (PV)

Purchasing a photovoltaic (PV) solar system can be incredibly exciting but highly confusing at the same time, with many questions needing clarification in advance. What are photovoltaic systems and how do they generate energy? What are bi-directional meters and do you really need them? How about small-scale technology certificates, feed-in tariffs and other essentials that require basic understanding?

Scholz Solar can shed some light on these essentials so you will have confidence and peace of mind in your purchase decision.

Photovoltaic Power Generators: The Heart of Solar Energy

Photovoltaic (PV) panels (or solar PV as it is commonly known) are the very core of a solar system. Photovoltaic panels work by “absorbing” solar radiation from sunlight through the solar cell and transforming it into direct current (DC) which is delivered to the inverter.

The inverter then converts the DC to alternating current (AC) which in turn is delivered to the electrical grid. Photovoltaic power generation uses panels consisting of a number of solar cells containing a photovoltaic material. As a result, PV panels generate larger quantities of electricity to power your premises.

Due to the growing demand for renewable energy sources, the manufacturing of solar cells and PV systems have advanced considerably in recent years. The market today features many different kinds of solar panels, varying in price and degrees of effectiveness.

To ensure you have the right solar panels and system for your needs, contact our solar installation professionals. We’ll be able to recommend a solar solution based on your usage specifications.

Essential Equipment for Your Solar System: Bi-Directional Meter and More

Depending on its complexity, a solar power system can feature many additional types of equipment.

The most essential component is a bi-directional meter. A Bi-directional meter is used to measure incoming and outgoing power to a site, replacing electricity and gas meters. So if you have a solar system and plan to get paid for the power you are feeding back into the grid, one of these will need to be installed.

Bi-directional meters make a lot of sense for a solar system, especially if you don’t consume all the power generated. The power you don’t use can be monetised via a feed-in tariff (more about that one – later). Smart meters display exactly how much energy you are using and send out readings to your suppliers, ensuring accurate energy readings instead of estimated energy usage over the billing period. The rebate will depend on the state you live in, local regulations and your electricity retailer’s policies. Talk to Scholz Solar to discuss rebate requirements in your area.

Save With Solar: Certificates & Rebates

Solar installation can benefit you in more ways than the mere production of clean power. In addition to saving the planet, there are special certificates, rebates and funding options to encourage the installation of photovoltaic systems.

When it comes to such facilitation, two of the most important terms you need to know include the small-scale technology certificate (STC) and the feed-in tariff.

Small-Scale Technology Certificate

You can claim an STC through the purchase of a renewable energy system or a solar hot water system. It provides you with an initial discount on the cost at point of sale. In essence, the STC is a commodity you can use to trade.

The number of STCs assigned to you will be determined by the wattage of the panel system installed on your roof, in other words, the size of the system installed. The total number of solar credits for each system is derived through the use of a multiplier – ie it multiplies the number of STCs your system creates.

To find out more about STCs, look on the official Australian Government Clean Energy Regulator website. There are several steps you’ll need to complete in order to qualify for the STC scheme.

To generate 1,000 kWh, our team suggests installing at least 27-30 solar panels on a typical Australian home. However, the exact count hinges on various factors. Speak to a specialist for your specific needs.

In Queensland, a new solar PV system installation ranges from $4,200 to $10,400. Smaller systems (below 3kW) generally cost $4,000 or less, while 4kW systems or larger start around $4,800. Check out our packages for more information.

As a rough estimate, a 6.6kW solar system could save you over $2,000 annually on power bills. Achieving $500-$600 quarterly savings requires substantial daytime power usage, potentially up to 30 kWh during summer days.
