Solar panel installation cost in Austin

The size of a solar panel system also plays a role in how much the installation will cost.

Larger solar installations will typically have a lower cost per watt, because the panels can be purchased at a ‘bulk price’. However, these larger solar systems will still have a higher total cost, because they are made up of more individual panels.

Why solar panel cost should not be your only consideration when buying solar panels for your home

The most important difference between buying solar panels and any other purchase is that solar panels last 25-30 years. This is a long, long time and you will need customer service over all that time. The reviews below of the two largest corporate solar installation companies indicate larger corporate solar companies are not delivering this support to their customers.

We recommend you find a small or mid-size, local, family-owned solar company. These companies tend to care more about you and your specific job. You don't want to be on hold to a corporation's call center for the next 25 years!

What other factors affect the cost of solar panels for your home?

The cost of solar doesn't just include the equipment and installation costs - it’s also made up of permitting costs, inspection costs, and installer profit margins.

These different components are what make the price of solar fluctuate between installations. Some of the factors that affect solar power system installation costs for specific homes include:

The amount of electricity your home uses

Homes that use more electricity will need more solar panels to cover their energy needs.

Although solar panels do get cheaper on a per-watt basis, the overall cost of the system will increase as more panels are added.

But, the higher a home’s energy usage, the more solar panels can save the homeowners on their energy bills.

The type of solar panels you buy

The price of solar panels can vary depending on the type of solar panels you choose.

There are two main types of solar panels for residential solar installations: monocrystalline and polycrystalline. Monocrystalline solar panels tend to be more efficient and more expensive than other solar panels. Polycrystalline panels have a lower efficiency rating and come at a lower price point.

The type of inverter you buy will also influence the cost of your solar system.

The quality of your solar installation

You may see some solar quotes with prices that seem too good to be true.

If you get quoted for a ridiculously cheap price, the installer might be using low-quality equipment or an unsustainable pricing model. You want to use a solar installer that is charging enough so that they can stay in business - as you’ll be relying on them for the next 25 years!

It’s important to make sure that your installer is giving you the best quality at the best price possible. This is why getting multiple solar quotes is so important.

Federal, state, and local solar incentives

The overall cost of solar can be influenced by the solar incentives available.

Across the U.S., homeowners can apply for the federal solar tax credit. The solar tax credit makes installing solar more cost-effective by providing homeowners with a tax credit equal to 30% of the cost of their installed solar panel system.

Local solar tax incentives and rebates can end up saving homeowners thousands on a solar installation, especially when they’re used with the federal solar tax credit.

How is the cost of solar panels offset by solar tax credits in Austin?

The cost of installing residential solar panels in Austin varies with the brand of solar panels and inverters you choose, the installation company you choose to install them, the relative ease or difficulty of installing solar panels on your home, and of course the amount of solar panels you need. The amount of solar panels you need is, in turn, related to your energy usage.
