Everything About Solar Panels: Types, Costs And Installation

Solar panels are a real godsend. They reduce our dependence on fossil fuels and save us money on energy bills. But are they worth the investment? This article reveals everything about solar power. We wanted to provide our readers with the most valuable information possible, so we decided to get in touch with specialists. Why not learn from Velocity Solar who have multiple service locations including Ballarat and Geelong in the state of Victoria and have been in the solar game for awhile. You can find out more at Velocity Solar’s Facebook.

How Solar Panels Work

An array of silicon cells absorbs sun rays. A transformer converts this light energy to Direct Current (DC) electricity. A solar inverter converts DC to Alternating Current (AC) electricity which is fed into the grid or used in the house. Solar panels work efficiently when they’re exposed to direct sunlight. Power output drops when it’s cloudy and stops when it’s dark. Besides generating electricity, solar panels are capable of heating water.

Solar Power Investment

The cost of solar technology is dropping at a staggering rate. How long your new system will take to reimburse itself depends on several factors. These include the cost of your solar panels, how much power you use, local electricity rates and your system’s size or output. Get the full benefit of your system to avoid paying high electricity bills.

Types Of Solar Systems

Battery storage or solar hybrid is the in thing. This system is extremely efficient. It stores the energy solar panels produce for later use.

  1. Grid-connected (on-grid) systems draw power from the sun all day long. The system shifts to grid power at night or if it’s cloudy.
  2. Hybrid systems are on-grid and have a backup battery. At night, they power your home using the power stored in the battery.
  3. Standalone systems aren’t grid connected. They only generate electricity during the day.

Solar Panel Cost

Cost varies according to the panels you choose, the size of your system and where you live. Other factors that influence your expenditure include:

  • Installation costs, especially labour
  • Size of the inverter
  • Height and design of your roof
  • Framing cost
  • Fees for grid connection
  • Meter change or switchboard upgrade
  • Removal of trees and other shading elements
Let’s Delve Into The Details
  • System size – Most residential systems are either 3.0kW or 5.0kW. A 1.5kW system is cheap but produces little energy.
  • Installation – A straightforward installation is cheaper than one that needs frames to hold the panels in place.
  • The brand – Choose a reputable brand, not the cheapest. It’s more efficient and comes with a longer warranty (at least 25 years). Budget brands end up costing more and may not qualify for government rebates.

What Are The Exact Costs?

As a rough guide, it costs between $2500 (for a basic 1.5kW system) and $12,000 (for a premium 5kW system). Expect the price to range from $3500-$6000 for a 2kW system and $5500-$9500 for a 4kW system. A 10kW system starts from $13500. You’ll pay more for a high-efficiency brand, to buy several panels and if you choose a hybrid system that has battery backup.

Installation Of Solar Panels

Make sure your solar installer is qualified, accredited and licensed. Depending on where you live, a builder’s or electrical license may be necessary. Solar panels are either installed on the roof or on the ground.
