Sizing Solar Battery Systems for your Household Usage

If you plan to install solar panels at home, you must be aware of the factors needed to enhance their efficiency. The first and most important one is their direction which is different in each Australian state but North is the most used direction for solar panels as of now. Apart from that, the angle to which you are going to tilt the panels is another factor of key importance. Similarly, the number of panels and their location matter as well. 

In the same way, you’ve to install batteries as well to store the power generated by these panels which is why you must be aware of the kind of batteries you must install along with their sizes. Let’s take a look at the tables which will let you know about the sizing of these batteries.

Sizing Tables for Solar Systems

If you use the power generated by the panels yourself, you’re at the benefit of not paying any amount to get electricity. Also, if the use of electricity at your home isn’t that much, that’s another great thing. The reason is that exporting electricity from Mains power in Australia is too costly and is unaffordable most of the time. 

The following table is showing the range of consumption along with the sizes of solar panels so that you may get an idea of which size is better in terms of usage and why.

Daily Consumption of power	Size of Solar system
	2kW	3kW	5kW	7kW	10kW
5-10kWh	30%	25%	17%	13%	9%
11-15kWh	48%	38%	26%	20%	15%
16-20kWh	57%	46%	34%	26%	20%
21-25kWh	66%	53%	40%	32%	24%
26-30kWh	73%	59%	44%	37%	28%
31-40kWh	82%	67%	50%	42%	34%

A red cell means the system is quite comfortable with the batteries and there is no way you need to replace the batteries. However, if it is green, the payback period of this size of your solar system will be favorable to a large extent. 

This table is based on general calculations and isn’t taking into account any of the above-mentioned factors such as your location, the angle at which the panels are tilted, and the direction. However, if you want to know all those things also, you either need to use an estimator or ask a professional to get that job done for you.

Conclusion 

These tables will help you get to know more about which size of solar system suits you the most and which one you should go for. So, once you get an idea, it’s up to you to decide which size of the solar system is better for you. This will ultimately result in an increase in savings for you.
