How To Know What Size Solar Power System To Buy

Solar power systems come in many different sizes which can accommodate a large range of homes. Buying solar is a great investment for your future and by knowing what to look for you can really make the most out of your solar system for the better. The following is a guide on how to choose the right sized solar energy system from your local thermal heating store without compromising on quality.

How To Calculate Solar System Size For Your Home

Check Your Energy Bill – Your energy bill is a great starting point to working out which system size you should consider. Solar panel systems that are larger in size can help to minimise larger bills. Smaller bills will only require a smaller amount of panels.

Daylight Hours – Depending on where you live, the amount of daylight hours and sun exposure your home receives throughout the day is also a deciding factor. Homes which are covered with shade most of the day won’t benefit much from solar panels therefore it may be best to go with a smaller option. Buy a panel size that can accommodate for your energy running costs in a day. Your local provider should be able to help you out with this.

Consider a Battery Storage Option – Battery storage options can be purchased at an additional cost. These are suitable for those who want to store additional power in a backup battery. These can be used on both small and larger systems and is a great investment for homes that use a lot of power.


Buying a solar thermal heating system is a great way of improving your savings in electricity. So what size panels are you looking to choose?
