While many homeowners and commercial owners like the idea of generating their own energy, there are a lot of considerations that need your attention. The system is more than just bolting photovoltaic panels on your roof. The overall cost of the solar system involves the cost of solar panels accounting for about 25-30 per cent only whereas, the other portions of the cost comprises the complicated procedure of planning, other expensive electrical components, technical know-hows, and the hard work that goes into creating a system that’s compliant, reliable and safe.
So, if you’re considering installing solar panels at your home, we need you to look at five essential things that you should understand. All these questions are related to how your residential solar energy system will work.
Important Solar Acknowledgement
Are inverters an important component of the solar system?
Your household power generates Alternating Current (AC), whereas solar panels generate Direct Current (DC) power. On the other hand, an inverter converts DC power output into AC power. As inverters are rated in watts, they must match the panel's output voltage.
While converting the power, inverters lose some amount of heat. This loss of energy affects the efficiency of the system and equipment directly, eating up some watts that you could have used. So, to protect your investment, Sunshine Coast solar experts prefer equipping inverters with sensors that shut off if some fault shows up.
Should you have a grid tie-in or grid with backup?
Having a grid-tie-in system means taking advantage of both solar panels as well as getting power supply from your utility connection. What’s the problem then? In this system, if the utility power goes off, the inverter shuts to prevent it from electricity feeding onto the power lines. Additionally, battery backups have added a lot of convenience in terms of cost and complexity. Many battery-backup grid-tied systems come with an inverter that shuts off the contact with the utility as soon as its power goes off. Controllers/regulators are also required to regulate voltage and the current coming from the panels so that overheating and damage is prevented.
What is meant by safety disconnect?
When it comes to safety, solar power requires several power disconnects. One of these disconnects is the DC fuse. The voltage can be high as the solar panels are wired in a series that adds panel voltages together.
At the battery connection, the two other disconnects are the regulator and the AC output connection.
How much sun is needed for general solar panels?
Where you place your panels and the location you live at directly affects the amount of energy the solar array can generate. Thus, the amount of sun that your region receives is called the insolation value. This insulation heavily depends on the angle of the sun in your area. Also, where you place the solar panels matters too.
How many solar panels do you need?
The number of panels depends on the isolation and your energy consumption. Firstly, you need to know what your watts usage is. So, for instance, if you’re putting the system on a roof, its size will determine the number of panels and its kind.
According to the rule suggested by Sunshine Coast solar experts, the cost per kilowatt-hour decreases when you increase the size. Plus, you may end up buying an inverter and other controllers. Thus, reducing your electricity usage will significantly increase the value of your system.
