If you want to install a solar panel system for your home, first you’ve got to look around and obtain several estimates. However, between the various products, the dollar amounts, and the kilowatts suggested in each, it can be difficult to know which option is the most ideal.

After you have obtained several estimates, there are 2 primary parts to focus on. First, the supplier or the installer that has established the estimate and the solar panels that have been suggested.

The Installer

One of the primary parts to get right is the solar installer and/or supplier. It is crucial to guarantee that the installer is accredited by the Clean Energy Council. Also, they need to come to your house to conduct an evaluation before offering you the final estimate. The reason for this is that your switchboard, your home’s configuration, and other individual aspects can affect the final cost.

  • Ask the Correct Questions

You shouldn’t be scared to ask the installer any questions you’ve got when comparing estimates. Solar is a huge investment. If you want to get the most out of it, there are no funny questions.

A couple of excellent questions you may like to ask include:

  • Do you have the contact details of a recent client I can talk to? Do you have any testimonials?
  • How many installations have you done?
  • How long have you been in the industry?
  • What is your accreditation number?

The Solar Panel System

  • Solar System Costs

You’ve got to ensure you are comparing the expenses without including rebates since you might not be qualified for them.

If you’ve got an estimate that is a lot lower compared to others, it may be a sign that the installer is cutting corners to accommodate for the low rate. You shouldn’t be scared to ask them why their estimate is a lot cheaper.

  • Solar Warranties and Products

When comparing solar estimates, you’ve got to guarantee the system parts’ quality is all the same. For instance, make sure the solar panels estimated are coming from a reliable and reputable supplier.

Also, it is vital to look at the warranties provided. Solar panels will last for 2 decades or more. Thus, you’ve got to guarantee the system is covered under warranty.

Usually, warranties will include:

  • Battery – Ideally 10 years (Minimum 5 years)
  • Inverter – Minimum 5 years
  • Panels – Some provide a product warranty of 2 decades (minimum 1 decade)
  • Workmanship – 5 years

Also, it is worth checking whether the manufacturer is based locally when it comes to warranties.

Solar System Size

The solar supplier or installer will consider your energy goals in the future, your budget, and your energy usage when establishing your estimate. With these details, they will be able to size up a solar panel system for you.

However, it can be hard to know what’s ideal if you acquire several estimates all suggested various sized systems.

As a rule of thumb, it isn’t perhaps worth your time installing a solar panel system less than 3 to 4 kW if you’ve got a 3-bedroom house.
