When should you not buy a solar power system?
Solar power systems are transforming homes and businesses across Australia. What you should be aware of though, is that while many homes and businesses work well with solar, there are some situations where installing a solar power system might be not be the best answer for you.
The first thing you want to look at is your roof. Does it have a complex design with limited space? This might mean you don't have enough area for solar panels, or it might mean you can't fit enough panels up there to give you a good return on investment.
Next, you want to consider the direction your roof is facing, and the factors that effect your ability to produce solar power. Is your roof south-facing? Is your roof shaded by trees or other buildings? While technologies such as panel optimisers or micro-inverters might help you here, in the end, you still may not be getting enough out of your system to recover your investment.
You also need to consider the condition of your roof structure too. If it's made from asbestos or in a bad state, that money might be better spent on replacing or fixing your roof before you install a solar power system, otherwise you'll be increasing your costs by having to remove and re-install it all over again.
Finally you also want to take into consideration things like your energy use profile and your feed-in tariffs, which will both effect your payback period for the system.
All of this factors into whether or not a solar power system will be cost-effective. If you have questions about whether or not a solar power system is right for you, a reputable solar installer can help you to evaluate your property to see if solar makes sense for your individual circumstances.
