Frequently Asked Questions – Solar Energy

We've answered a range of questions frequently asked about the Solar Wise Photovoltaic Systems. If your question isn't answered below please feel free to contact us.

How long will the sun produce our solar energy?

The sun has produced energy for many millions of years and will do so for many millions more. It is estimated that there is still enough hydrogen in the sun's core to last another 4.5 billion years. Solar energy as we refer to it is the solar radiation (light and heat) that reaches the earth. Every day the sun radiates enormous amounts of heat and light energy. The planet and the atmosphere absorb some of this energy with the remainder being reflected back out into space.

How does the sun’s solar energy compare with human energy consumption?

The amount of solar energy reaching the earth's surface is 6000 times the amount of energy used by all human beings worldwide.

What are the advantages of renewable energy?

Unlike fossil fuels, renewable energy sources will never run out.  Renewable energy facilities generally require less maintenance than traditional generators. As their fuel is derived from natural and available resources, it reduces the costs of operation.
Even more importantly, renewable energy produces little or no pollution such as carbon dioxide or other gases, and so has minimal impact on the environment.

What can affect the amount of solar energy received?

The strength of the solar energy available depends on the time of year, the time of day, and the latitude of the generation point. The amount of energy generated can be further affected by the amount of dust and water vapour in the air, and the amount of cloud cover.

What is a solar module and what does it do?

A solar module is a device which converts sunlight into direct current (DC) electricity. It produces electricity suitable for use in your home and for charging batteries.

Are there different types of modules?

Yes, there are various modules with different power ratings measured in Watts. Solar Wise Wagga has a range of modules that cater for a variety of applications.

What type of solar power systems are there?

There are two main types of solar systems, standalone and grid connect. Grid connect systems, often located in built up areas, supply solar electricity through an inverter directly to the household or the electricity grid if the system is providing more energy than the house needs. Standalone systems usually operate in remote areas, away from power supply lines or where supply can be unreliable. The electricity generated by the system is usually stored in a battery bank consisting of deep cycle batteries which are suited for repeated partial charge and discharge.

What does a typical home solar power system consist of?

A simple standalone system would typically consist of a few solar modules, a solar regulator, an inverter and a battery bank. Sometimes they work in conjunction with other forms of generators, for example wind or diesel, to charge the battery bank. A simple grid connect system consists of a few solar modules and an inverter which converts the DC electricity into AC and is connected to the power grid through the electricity meter.

How can my system generate 240V AC?

This can be achieved by installing an inverter into the system. The inverter converts DC electricity into 240V AC. Solar systems are versatile and can be designed for both AC and DC, or can be converted at a later date. Solar systems can also be expanded to grow with your needs.

What about cost?

Each system cost will be individually calculated according to your needs. Solar wise Wagga offer a full no obligation quote and site assessment making sure to maximize the solar energy available on your site.

What happens during a blackout?

During a blackout, your system will automatically shut down too. It is a requirement of the electricity supply authority that your system is isolated from the grid for safety reasons when the grid is dead.
