Once the solar tax credit this leads to a range of around $6,195 – $7,350.

Then again, the cost differs by areas and likewise determined by if the setup is bought for cash or if the setup is loaned. Many solar loans offer come with an application fee of around 10 to 12%. Thus systems that are funded are generally 10 to 15% more costly.

The above figures can serve as a point of reference for you as you initiate the process of shopping for a solar power system for your household. Even so, a number of elements can impact the expense of your solar power system. Such as, if you decide to set up high-efficiency components or want particular accommodations for a sophisticated roof, your system will surely cost extra.

How many panels & how much roof space for a 3kW solar?

To install a 3kW solar setup, 12 solar panels will be needed, supposing that you choose 250W panels. Every panel will be approximately 1.6m x 1m, hence you will be required around 20m square of roof area.


How much electric power will a 3kW solar system generate?

That will depend on plenty of situational conditions including location, orientation, and direction of the panels, the existence or a shortage of shading as well as the overall performance of the parts in the system are primary of them.

It is easy, to sum up, solar system outcome in one number – such as kilowatt-hours per day (kWh/day). However the truth is that a lot of places get more sunlight during the summer as compared to the winter; consequently, solar power energy production will most likely be higher during the summer and reduced in winter months.

Supposing an unshaded south facing array a 3kW solar power system will generate around 8.7 to 13.8 kWh daily on average over the 12 months with respect to the area in which it is installed.

What Parts Do You Need

This raises a major point. It requires more than a solar panel to have a solar system installed and operating. The truth is, you will find generally 4 parts in every single solar system:

  • Solar panels – catches sun’s energy and turns it to electric power
  • Controller – defends batteries by controlling the circulation of electric power
  • Batteries – save energy for later use
  • Inverter – changes energy saved in a battery to the voltage required to run regular electrical equipment.


How much do solar panels save on electric bills?

Your present electricity bill is the major element in finding out just how much you will save by setting up solar. You pay your electric company for each kilowatt-hour (kWh) of electric power you use. Your rate differs considerably according to where you reside.

For a typical household, a 3kW solar system will generate roughly the same as about 2/3 of total electricity utilization. But be warned; in case you have a pool pump, ducted air-con, and a home automation system inside your big house then it will not make a great deal of reduction in your electricity bills!

The exact amount you can save with 3kW system is roughly $500 to $850 yearly. Which means that for the 20 years, when you qualify for the Feed-in Tariff, it can save you $13298. Also after all those 20 years, you continue to cut costs due to free electric power.

On or off the grid?

As solar panels just produce electricity simply because the sun shines, you will need to have a way to store the power. Although it is feasible to use a battery for storage, the simplest (and most affordable) option for many people is usually to stay attached to the grid.

In case your solar panels are generating extra energy than you are using when you are at the job, on holiday, or perhaps not running various devices, excess electricity will move back into the grid. In lots of places, electric companies provide a program known as “net metering”. This can pay you for the additional electric power you generate.

In the evening, or whenever you require extra electric power, you will draw it through the grid. Using a grid-connected system, you will never have to stress in case you need more electric power than your solar system can supply. You may also want to supply only part of your average electric power bill with solar power and make use of the grid for the rest.
