General checklist for buyers:

Depending on project-specific conditions, photovoltaic systems may or may not be a large investment. If you are considering installing a photovoltaic system for your home or business, ensure the following checklist before buying solar systems.

1) Sunlight

There are four main factors that determine whether a potential location receives enough sunlight for a solar PV system to be profitable are Geographical location, local weather, Alignment of the roof and other obstacles. These factors determine the amount of direct solar radiation that reaches the photovoltaic system and, in a broader sense, determine the energy output.

2) Shadowing

Shadowing can be a serious problem if not taken into account because the shade of one solar module is enough to reduce the production of the entire string. However, please note that when installing arrays, small shadows can be avoided and Locations, where solar photovoltaic systems are installed, must have a minimum shade. PV roof systems have improved performance when installed in a favorable orientation.

3) Is your energy at your location expensive?

Expensive energy means saving more money per kilowatt-hour, produced by solar photovoltaic systems. Production of 1000 kWh saves 100 US $ at 0.10 US $ per kWh. However, this amount will double if the utility charges $ 0.20 per kWh. If energy is expensive, the payback period is shortened because of the savings per kWh increase.

4) Are there incentives from local authorities?

Some governments offer tax credits and tax exemptions to homeowners and companies that invest in solar energy. 

5) Warranty in Perth, WA

Solar power plants must have about a lifetime. 25 years. Typically, solar modules have a 25-year performance guarantee, although other components of the solar system may have different / lower performance guarantees.

6) Support and Maintenance in Perth, WA

The rooftop solar system will only provide a full return on investment if it works as smoothly as possible. This means regular checks on individual system components. Timely intervention avoids the risk of production decline or downtime or security risk.

7) Permits, Approvals, and Subsidies in Perth, WA

In the solar system for a grid roof, operators must meet all the requirements needed for the installation of network meters. This may require additional time and costs depending on the local power supply. Permission is not required for battery-based systems. However, if the subsidy scheme is offered by the government, additional subsidy documents may be needed.

8) Lifestyle

Solar energy is produced during the day. Soon, economical battery storage will be available. However, it is important to evaluate at this time how much energy is used during the day. If your property is empty most of the time, most of the electricity is likely to enter the grid. 

9) Do you have your property?

If you are not a property owner, the investment may not be justified – unless your landlord/broker wants to share costs or make investments on your behalf to exceed the increase in rental rates.

The cost of a fully installed 9kW solar system has dropped dramatically in recent years.

4. How Many solar panels are required for a 9kW Solar Power system?

The 9kW solar system consists of 28 to 36 solar panels. The efficiency of a solar module is determined by the amount of energy that is converted from sunlight into electricity per unit area. This means that comparing panels of the same size gives more efficient panels more power (in watts). High-performance panels are usually expensive, so it is very useful when space on the roof is limited. By using high-performance panels, the homeowner can maximize the amount of solar energy he can use because of the size of the roof. 

It depends on how much electricity you consume, where you live, what roof characteristics you have and what percentage of your electricity bill you want to reduce.
