Whilst there are numerous high quality brands of solar panels on the market, Delta Electrical & Solar will always recommend REC solar.

Although they are positioned towards the higher end of the spectrum, they come with a 20 year warranty, compared to other more affordable brand that offer 10-15 years warranty. To help you afford the REC solar panels, we can offer interest free payment plans.

At Delta Electrical & Solar, when we install your REC solar panel system you get an additional 5 years warranty as we are authorised partners - that’s a total of 25 years product warranty!

We offer many other solar solutions for our customers, which include but are not limited to – Jinko solar , Winaico Solar. We do not sell LG solar panels. See us in action installing REC twin peak solar panels in our video here!

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.

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.

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!

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!
