• What are the applications of solar power in our daily life?

  Solar electricity can be used to power households, RV's, commercial and industrial uses. Solar electricity is identical to power generated from fossil fuels, wind & hydro. Solar electricity is generated only during daylight hours and is best used to cover daytime power use rather than consuming from the grid and the power company. One of the keys to successfully making...

• What does solar power or solar energy mean?

  Solar energy is the term used to describe the light and heat produced by the sun. Solar power is the conversion of sunlight into electricity. Direct conversation of sunlight into electricity is performed by Photovoltaic (PV). The word 'photovoltaic' is composed of two terms: "Photo" which means light and "Volt" which is the unit used to measure electric potential. Solar systems use PV cells (ca...

• What is the difference between solar hot water systems and solar energy for electricity?

  Solar hot water systems, sometimes called solar thermal systems, use the direct heat from the sun to heat water, whereas solar photovoltaics "pv" uses sunlight to produce electricity. They are two very different types of technology. Both solar technologies use panels to collect the suns energy. Solar hot water panels have black copper pipes running through them filled with...

• Is solar hot water and solar electricity the same thing?

  They are two different technologies used for different applications - one for generating hot water (Two panels in foreground) and one for generating renewable electricity ( Six panels in background). Both technologies use collectors - also known as solar modules or solar panels - usually installed on the roof. The source of the energy for both technologies is same - the sun, but the technology...

• How does a solar power system work?

  A solar module is made up of a group of photovoltaic cells. They consist of 2 layers of silicon wafers which become positively and negatively charged when sunlight hits them. The charge created flows through a circuit of small wires connected to the wafers. The PV modules generate Direct Current (DC) electricity and send it to the solar power inverter. The inverter transforms the DC power f...

• Can a solar system reduce my electricity bill to zero?

  A solar system can generally make a substantial dent in a households electricity bill. Savings of many thousands of dollars a year are possible for big residential power users but achieving a zero bill is difficult if not impossible in most Australian states. In Australia electricity produced though your solar system is either used instantaneously in the home, office or&nbs...

• What time of the day and during the year does a solar system work?

  Solar systems work best when the sun is shining. As the strength and angle of the sun varies throughout the day and seasons, so too does the strength of the sun's radiation and this affects the amount of electricity your solar power system will generate. The highest solar generation during the day is usually from 11am to 4pm. Days are longer in summer and shorter in winter and correspondingly, th...

• What happens with my solar system at night, in cloudy weather or during rain?

  Although solar panels still produce electricity in cloudy or hazy conditions, the clearer the sky, the better the energy production will be.Temperatures over 25 Degrees Celsius can also reduce the output of a solar system, especially with cheaper panels. Higher quality and more costly panels, like LG solar panels, will perform better in hot weather. As a rule of thumb, a solar system wil...

• Do solar systems need bright sunshine to work?

  Solar PV panels on the roofs of homes and businesses generate clean electricity by converting the sunlight's energy. The more energy in the sunlight received by the panel, the more electricity is being generated. Even in overcast conditions solar modules still generate electricity, however the output will be less than on a bright sunny day. In layman terms - the brighter (not necessarily hott...

• How much solar power do systems generate? What affects the output?

  Please try our solar calculator for your area to see how much electricity different sized solar systems generate. A number of factors can affect how much energy your solar system will generate. We have separated these into primary effects (the things that make a big difference) and secondary effects (the things that make a smaller difference). They include the following: Primary effects on ge...

• Can I save on electricity without investing into solar?

  Yes, households can save on power bills without solar panels. While solar can substantially reduce power bills it is also very worthwhile to review power use and waste less.Interestingly households who buy solar power take more interest in power usage and tend to get the double benefit of cheap solar power and lower power consumption. Huge financial savings can be made by this two pronged appr...

• How do I get paid for the electricity generated by my solar power system?

  Every watt of electricity generated by your solar power system and used by you directly in your house will save you money, as you do not have to buy this electricity from your electricity retailer. Therefore, it makes sense to use as much power as possible during the day when the panels are generating power e.g. by turning on pool filters, dishwashers and washing machines when the sun shines...

• Will the solar system help me reduce my green house gas generation?

  Greenhouse House Gas (GHG) is avoided by using solar power, with the typical focus on the most significant greenhouse gas from electricity generation which is Carbon Dioxide (CO2). In Australia each kWh of electricity generated from conventional sources such a coal, creates on average, approximately 1kg of CO2. According to the Australian Energy Market Commission, the average Australian home ...

• How much of the green-house gas (CO2) will my system save?

  How much CO2 is avoided depends on the conventional electricity it displaces and this varies by State/Territory and generation technology. In principle, solar creates no CO2 (or other emissions), other than during manufacture and transport.The CO2 emissions associated with the manufacture and transportation is offset by the panels operation within the first 16-18 month of operations in Austral...

• Is solar energy more expensive than conventional energy?

  In many countries, solar systems produce electricity at or close to the cost of electricity from other conventional sources, which continue to rise. When the cost of solar electricity matches the cost of conventional energy, we refer to this as “grid parity”. In Australia "grid parity" is now close in many areas or has already arrived in areas with high electricity costs. The more recent in...

• How do I know if a system is beneficial for me?

  The benefits of a solar power system depend on a number of factors including lifestyle, size of the house, number of appliances in the house, number of residents in the home, the time of use of electricity, use of pool pumps, use of air-conditioning etc. Be it in your home or your business - generally you will benefit most from solar energy if you can use the electricity generated then and t...

• When is solar NOT suitable for my home?

  Most homes and businesses in Australia are suitable for solar energy; There are, however, a few instances when a solar power system is not worthwhile. Some examples include: 1. Very small daytime power users who only have south facing roof. Generally even exporting almost all solar power back to the grid and collecting the feed-in-tariff will save a household some money over...

• Are there any Australian Standards in the solar field?

  Solar industry is well regulated in Australia with Australian Standards regulating the product as well as installation and maintenance. Below is a list of the major Australian Standards: PV & Inverter Standards AS/NZS 5033:2005, Installation of photovoltaic (PV) arrays. AS 4777 Inverters AS 1170.2 Wind loadings. Grid Connected Solar Electric Systems AS/NZS 3000:2007, Wiring Rules....

• Please explain the difference between kW and kW/h?

  kW stands for kilowatt, or 1,000 watts. It is a measure of power. Your LG solar power system is rated according to the number of watts it can produce each hour. This solar panel rating is seldom fully achieved in real life conditions, as dust particles and clouds constantly affect light quality. For example 12 x 260Watt panels will make up a 3.12 kW system. Normally you would then also use a 3 kW ...
