Find answers to the most asked questions about solar energy
Solar power can be confusing if you’re new to the terminology and concepts of renewable energy. Please read our solar power FAQ where we have compiled answers to common questions.
What should I look for in a solar panel installation?
Look to buy local and only purchase a system from a company that is prepared to come to your property and discuss your best options. A solar panel installation is a significant long-term investment so another important factor is quality. Your system will produce electricity for 30 years of more so every component must be durable and reliable. The quality of the panels on the market varies, as does the quality of the installers, so for the best results purchase guaranteed Tier 1 products and have your system installed by a reputable solar installation specialist.
Is solar right for me?
Solar panel installations are most commonly used as a source of energy in regions with high irradiation levels and available incentive programs. Australia, with an abundance of year-round natural sunlight and generous incentive schemes, is an ideal place to invest in a solar system.
Can I insure my grid connect system?
Most insurers will allow you to include the system under your current insurance policy. Please
check with your insurance company.
How can I finance the installation?
A solar panel installation is considered a safe and steady investment. If necessary, you can finance your purchase through, operating leases, bank loan, home improvement loan or mortgage refinancing. It is best not to get your finance through a solar company, we sell solar not finance.
If my energy requirements increase, can I upgrade the system?
Yes, Additional solar panels can be added at any time to increase generating capability but you might have to upgrade to a larger inverter. Alternatively, you could purchase a larger inverter when installing the system initially and then plan to add some extra solar panels later.
How many solar panels are needed to power a property?
The appropriate sizing of a solar power system to supply a properties electricity needs is one of
the most common questions people considering solar panels ask. OTI Power offers a number of
tools and ways to help you determine a return on investment, panel placement, location of
inverter and best sized system for your property and circumstances.
Does roof orientation really matter?
Most certainly. For example, a system with solar panels facing in a southerly direction will generate far less than one with a northerly aspect. However, east/west installations can be a good option depending on the installation scenario.
How much roof space is needed?
1.0 KW system needs approximately 10m2, a 1.5KW system needs approximately 15m2 and so forth.
What is the weight of the solar system on the roof?
The system weighs approximately 27 kilograms per square meter so not an issue for
Residential or Commercial properties.
Have realistic expectations
If you are paying substantially less than many other similar size systems quoted, you may find poor quality equipment and/or poor installation work. Quality equipment and installation aren’t cheap and, like all other purchases, you often get what you pay for. Compare components and warranty periods and check into the company providing the installation.
