Below we explain what you need to know before installing a solar photovoltaic (PV) system on your roof.

How a Solar Energy System Works

The following is a simlified explanation of how do solar panels work:

  • In order to generate electricity, the solar panels, which are outfitted with an array of solar cells, absorb solar radiation from sunlight and produce DC electricity.
  • The inverter then converts the DC electricity into AC electricity, which can be used to power household appliances and others.
  • When an on-grid solar power system generates excess electricity for a home, the surplus energy is fed into the local utility grid and depending on the electricity company, entitles you to a credit on your next bill.
  • At night during off peak, when the system is not working, the electricity used in your home comes from the mains power, unless you have a battery storage system.

Energy Audit

Do not guess your household power consumption patterns. Get qualified advice from engineers who will use your Meter Data to model Solar PV viability and put together the best possible solar PV solution for your household. GRES offer a free energy audit and consultation.

Clean Energy Council Accredited

With so many solar system providers to choose from make sure you choose a solar panel provider that is “Clean Energy Council Accredited”. This is a qualification that the person installing needs in order for the government to pay out its rebates. GRES residential solar panel systems are designed and installed by CEC accredited solar electricians.

Research Brands and Prices

There are some very cheap solar panel offers in the market, but these cheaper deals can hide poor quality equipment that are made to appear like quality products. An inverter is the heart of your solar system so choose a quality Inverter solution to go with quality panels. GRES supply a full range of high quality premium solar panels and inverters backed with warranties.

Solar Panel Mounting

Does your roof have shade or partial shade? In residential applications, solar panels are normally installed on roofs. So, if your roof is shaded at certain times of the day or is partially shaded most of the time, then the amount of electricity your system is able to generate will be lesser compared to a system with continuous sunlight. Also, check whether your roof is in good condition or not before a solar installation as a typical solar installation lasts for up to 20 – 30 years. If your roof is in poor condition, consider updating it so you can avoid paying for additional costs coming from the removal and reinstallation of the system. GRES engineering services include site identification and assessment.

Know Your Finances

Understanding your finances is the key to success when shopping for a residential solar system. Well financed, properly sized solar systems could save you more money every month than it costs you to finance, even including interest. GRES can install PV systems on your premises without any upfront cost. Our partner financiers are ASM Money and Solar & Energy Finance.
