Finding out the appropriate size solar panel for your needs can be a daunting task if you do not perform proper study.

Sales representatives of the Best Solar Company in Australia give offers to customers to purchase the largest possible system. It is because they receive incentives for that. But it might not be the best choice always because the return on investment may not be the highest.

Feed in tariff rates (the rates you will be paid by the electricity retailers) have dropped considerably in the last decade. This has led to an important design principle that you should take into account.

The solar system that provides the greatest return on investment matches the solar output daytime energy needs of a household.

Matching solar power generation to the energy requirements of your home will minimize the amount of excess energy that is sold to the grid. Experts feel that selling power back to the grid is no longer a financially viable option because the feed-in tariffs are dropping every year. Therefore, you should pick the right Solar Panels in Sydney.

What is the upper limit of solar panel capacity that can be installed on your roof? It is a question that doesn’t have a simple answer. Some important aspects of it are roof area, energy-saving goals, and restrictions or terms and conditions imposed by authorities if any.

Your roof area, energy-saving goals, and any applicable restrictions imposed by your local electricity company are all part of this multi-layered question. The most popular size of the solar system is 6.6kW.

If you are thinking of a solar system expansion for your home, you will definitely want to know about the system size, which would be the best for your conditions.

As a general rule, the affordability and compliance with Australia’s network requirements of a 6.6kW solar system make it easy to get approval and export (along with a feed-in tariff).

A system of this size supplied by the Best Solar Company in Australia will typically generate a substantial amount of energy.  In most cases, the system will generate sufficient excess solar energy to charge a battery bank later on if you choose to do so.

Regardless of whether you have batteries or not, any solar energy that you do not use directly within your home will be eligible for solar feed-in credits on your electricity bill, so it’s not a big issue if you have a system that is generating more energy than you need.
