Understanding Solar Energy
GRES provides a comprehensive domestic and commercial solar panel service from initial feasibility and design, through
to installation and ongoing operation and maintenance. With this extensive experience throughout Melbourne, GRES
has put together some commonly asked questions solar energy and solar panels.
Solar energy is considered renewable energy with two main types of solar energy technologies.
• Solar Thermal: this is using solar energy for heating with the most common use being water heating such as hot water systems.• Solar photovoltaic (Solar PV): converting sunlight into
electricity using photovoltaic cells. Solar PV systems often found on rooftops or integrated into building designs.More than 2 million Australian households now have solar hot
water systems or solar photovoltaic (Solar PV) systems on their rooftop.
Solar photovoltaic (Solar PV) facts
Requires no fuel to operateProduces no CO2 emissions during operation
Is silent in operationCan be building integrated or rack mounted
Can operate for 25 years or more with virtually no maintenance
Basic principles
Photovoltaic cells are mounted together in a module or solar panel
Cells produce direct current (DC): the type of electricity stored and delivered by batteries. Most electrical equipment runs off alternating current (AC), as supplied by most electricity grids throughout the world.
So a PV system usually needs to be augmented by an inverter: an electronic device that converts DC electricity into AC.
The majority of solar PV installations in Australia are grid-connected systems.
How much electricity do Solar panels generate?
Goals and reason for installing Solar Panels Site Selection
Design
The amount of electricity generated from the solar panels installed will depend on a number of factors such as:
For these reasons call GRES, Global Renewable Energy Solutions consultants first to assist on the feasibility, site selection, and design of
your solar panels.
Solar PV and Battery Storage
Solar Energy is intermittent In a grid-connected Solar PV system, customers sell
their unused electricity to the grid, often at a very low price (usually 3-4 times of what they pay when buying from the grid)
Households and businesses can avoid this, as well the ever growing electricity price by switching to the Solar PV with Battery Storage
The excess electricity will be stored in the Battery Storage and can be used when needed
