Abundant and continuous energy is emitted by the sun in the form of radiation which can be stored as solar energy.
Solar energy can be harnessed by various techniques like solar heating, photovoltaic, solar thermal energy, solar architecture, etc. The solar energy is a clean, renewable and reliable form of energy.
Solar panel :
The solar panel contains photovoltaic (PV) module which helps to convert the energy from sunlight into direct current (DC) electrical energy. This DC energy is converted into alternating current (AC) for your home’s electrical circuits using an inverter unit.
The excess of energy which is not used by the home appliances can be fed back to the electricity grid, for which you may be paid an agreed feed-in tariff.
This excess energy can also be fed into a battery storage system which can be used later. The various types of solar panel includes monocrystalline panels, interdigitated back contact solar cells (IBC) and Thin-film solar cells.
Installation of the solar panels :
In today’s world, most of the people are moving towards the use of solar energy as it produces greener energy and also helps in cost saving in the long run. For setting up of the solar panels, various parameters should be considered for giving the best output.
Solar panels should be facing north, pointed towards the sun and also should be such that the rays are not blocked by trees or shading. Final output also depends on weather conditions. Points to be considered while buying and installing the solar panels in Adelaide SA include:
- Standards – Solar PV system should be such that it should meet the Australian and international standards. Solar panels must be certified which helps to obtain the eligibility for small-scale technology certificates.
- Capacity – Currently, no much money can be made from by feeding electricity back into the grid thus one has to maximize their own use of your solar PV and minimise your export into the grid. One needs to calculate the amount of electricity that is required for the household appliances during daylight hours while the panels are generating energy. This information can be used to determine the size of the system that will be able to suffice the needs. If less energy is used during the daytime than the smaller system will be sufficient. Availability of the space on the roof top also plays an important role in deciding the capacity.
- Warranty – The manufacturer of the solar panel provides a warranty ranging up to a period of 25 years.
- Budget – The cost of solar panel depends on the factors like the size of the system and quality of the components that are used. Majority of the cost is incurred during the installation whereas maintenance charges are very less for the solar panel.
- Storage battery – One has to include a battery into the system if the generated energy is to be stored for later use or to use during the night time.
- Solar incentives – There are two main incentives which help to pay off solar PV systems. These include the small-scale technology certificates (STCs) and feed-in tariffs (FiTs).
