What is the best solar system brand?
Whilst there are numerous high quality brands of solar panels on the market, Delta Electrical and Solar will always recommend LG Solar Energy.

To help you afford the LG Solar Energy panels, they offer a payback period of roughly 7 years.

Purchasing a solar system can be a daunting process. It is sometimes hard to know what type of system or size system you need. Below is some basic information that will help you out.
Types of Solar Panels
There are 2 main types of rooftop solar panels, Polycrystalline and Monocrystalline.
There are lots of technical differences between the two types in the manufacturing process but when it comes to the end user and the efficiency of each panel, the difference is minimal.
The main difference to the end user is the way it looks.
String inverter, Micro inverter or power optimiser
Think of your inverter as the heart of your system — it’s one of the smallest components in the overall cost but the most critical. The inverter converts DC power produced from your rooftop solar panel and converts it into usable AC power for you home.
A standard string inverter in the most common inverter used for solar systems worldwide. It uses the simplest of technologies and therefore is the most cost effective solution. The Disadvantage of a standard string inverter is the level of monitoring it provides and less efficient in shady areas in comparison to micro or power optimisers commonly know as MLPEs.
The benefit of using a MLPE such as SolarEdge power optimisers are the individual control of each solar panel. When using MLPEs the solar panel in individually monitored and controlled meaning if shade from trees or even a cloud.
How much roof space is needed for Solar Panels?
Depending on the size of the solar system you wish to install, depends upon the amount of roof space that is required. On an average house, Delta will install approximately 20 panels, which equates to six kilowatts. In order to receive more power per square metre, we install a 300 watt high efficiency panel.
If your house is small house with minimal roof space, we can upgrade to a go super-efficient panel in order to further maximise the power per square metre. We will always try to install as many panels onto your roof as possible!
How big should your Solar System be?
The bigger, the better!
Although this is governed by the size of your roof, ideally you want to fit as many panels onto the north, east and west sides of your house. With the price of batteries currently dropping, larger battery sizes are now more affordable than ever. You do however need to generate enough solar energy to charge the battery, in addition to operating your household items throughout the day.
When it comes to choosing the size of your solar system, you always want to look into the future.
In five years time, you may want to install a air conditioner. You want to make sure that the size of the system you install now will be large enough to cover this increased energy usage. With electric cars also entering the market, charging your car at home will require a large amount of electricity.
The extra bonus is, if you generate an excess of power, you will be reimbursed from sending the electricity back to the grid! Win, win!

Delta will ask for your most recent electricity bill and use our premium SolarPlus software to create a detailed report. This report will outline an average of money you will save when using your solar system and how soon you will pay back the installation cost.
Maintaining your solar system
At Delta Electrical and Solar, we provide all of our customers with an in-depth maintenance schedule. We recommend that every six months, you remove any dust any dirt from your solar panels using water and a super soft sponge! Using soaps or any chemical agents will void your product and performance warranty. We also suggest that you give all of the little mounting brackets a check, just make sure they’re nice and tight still.
