What factors affect the cost of solar panels for your home?
There are many factors that affect solar panel installation costs with regard to specific homes,
The location of your home
The location of a home affects the cost of installing solar in a few ways. The amount of sunlight available affects system output and so dictates how many solar modules you will need. Obviously the more solar panels you need the higher the cost. Market prices are also different in different locations because of factors including average system sizes in that location, competition between installers, local job volumes, and the cost of business overheads.
The amount of electricity your home uses
A house that uses more electricity will need more solar panels. Although solar panels do get cheaper on a
per-watt basis, as the system size gets bigger, the overall cost of the system increases, as well.
The type of solar panels and inverter you buy
There is a significant difference in cost between the top-rated solar panels and brands that are perceived to be
of lesser quality. The same is also true for inverters. For example, a 6kW solar system using Sunpower or
Panasonic solar panels can be as much as $5,000 more expensive than a solar system using Canadian Solar
The relative ease or difficulty of installing solar panels on your home
If your roof is particularly difficult to install solar panels on, say, if your home is three stories high or
has a roof with a 45° pitch, it will take longer to install the panels and do the wiring.
How is the cost of solar panels for homes in Texas offset by solar tax credits?
The cost of installation of renewable energy systems in Texas is supported by the federal solar investment
The amount of this tax credit is currently 26% of the value of the solar system and it is claimed on your
taxes in the year after installation.
Many people mistakenly refer to this tax credit as the Texas solar tax credit but it is actually a federal
Texas itself does not offer a solar tax credit.
How does the cost of solar power compare to the electricity rates charged by a utility? (per kWh)
Levelized cost of power from this typical solar system installed on a home in Texas over 25 years is
Average cost of utility power over 25 years (if you don't get solar) is
20.4 cents/kWh. This shows that
solar is a far cheaper way to power your home in Texas over the long term. The way we calculate the
average cost of utility power is by assuming the current utility electric rates will grow each year at a
compound rate of 3.5%. Actual inflation may be higher or lower than this but either way this analysis shows
that solar is a clearly better choice.
Are solar panels worth it in Texas in 2020

As you can see the payback period is relatively short and equates to a much better return on investment than
he historical returns that have been available from investing in things like shares or property.

Tesla is one of the only companies that displays their installed system pricing online. We are encouraging more solar companies to do the same. They have a very poor
reputation for customer service on reviews websites like ours however we applaud their move to bring pricing transparency to the residential solar industry.

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!
