As electricity costs continue to rise more and more homeowners are choosing to install solar panels. Solar panels utilise the sun's rays to produce energy. This not only makes them an environmentally friendly energy source but also means that households can greatly reduce their energy bills by switching to solar power.
Before deciding to install solar panels, homeowners need to take several factors into consideration. These include the following:
Size and number of solar panels
This depends on a household's energy requirements. The best way to determine this is by studying previous power bills and checking the average amount of electricity the household uses in each time period as well as the average daily usage of electricity. Power consumption is measured in kilowatt-hours (kWh). Typically, in Australia, a household uses around 15–20kWh per day. However, this number varies between homes. Other factors to consider are the days of the week where the most power consumption occurs. For instance, the number might be higher on weekends where everybody is at home.
The size of a property's roof also limits the number and size of solar panels that can be installed. For smaller roofs, it is more suitable to install a smaller number of panels with a higher energy rating (higher energy rating means more power is produced). However, those with larger roof space will benefit from installing multiple panels as this will be cheaper.
One should have a rough estimate of the cost savings they expect to make by installing solar panels. $5,100 is the average cost of a typical 5kW solar system in Australian capital cities. This price is constantly decreasing as solar technology gets cheaper. It can take between two to seven years to make up the cost of the solar system; after this, households can really start saving. This time depends upon where one lives in Australia.
The Australian government encourages households to switch to solar power for the benefit of the environment. Households can apply for incentives; the amount of rebate a household can claim varies between cities, so it is best to check before submitting an application.
Before deciding to install a solar system, it is important to carry out thorough research and assess one's energy requirements. Speaking to professionals can help answer any questions one may have with regards to the size of the solar system and any government incentives.
