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.

What rebates are available?

Small-scale Technology Certificates, or STC’s for short, are available on PV Solar installations under 100kW. You’re eligible for STC’s whether you’ve previously accessed a rebate or not. The solar PV system or product you purchase in order to receive STCs must adhere to the Clean Energy Council (CEC) design and install guidelines, only use panels and inverters on the CEC approved list, These rebates differ between regions, so it’s worthwhile investigating what solar rebates apply in your area.

What are STC’s

Small-scale Technology Certificates. These certificates are a tradeable item and are created when you install a PV Solar system under 100kw. STC’s fluctuate but are currently worth approx. $36 per STC, providing a rebate of approximately $3,600 on a 6.5kW system. Our Solar proposals will show the rebate amount applicable to your area and size system quoted.

How do customers benefit from installing batteries with their solar systems?

Batteries installed with your solar system allows for households to store any unused energy to use at a later time, or to sell the energy back to the electrical grid. Other benefits include:

Reduce or eliminate the need to use the grid during peak times when electricity is charged out at higher rates. In other words, offset consumer feed-in tariffs.

The ability to deliver continued supply if the household is relying on an unreliable grid supply.

Is battery storage safe?

The use of batteries in conjunction with your solar system is safe when the batteries are correctly installed, correctly used and well looked after, There are potential risks that may rise if the above is not adhered to, which are in line with risks from many other electrical hazards that are present in any household.
