*Prices are shown after applying the 30% federal tax credit.
As of Apr 2024, the average cost of solar panels in Milfay is $2.37 per watt making a typical 6000 watt (6 kW) solar system $9,947 after claiming the 30% federal solar tax credit now available.
This is lower than the average price of residential solar power systems across the United States which is currently $3.00 per watt.
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.

Joseph and the install team just finished installing our system. They did a fantastic job making sure the array and equipment looks great. They were very professional and answered all of my questions. The plans were for a single array that spans the entire roof and the team took extra time to make sure everything lined up and everything looks fantastic!! They even went the extra mile to clean up the property and make sure I was happy with the install. I would definitely use Astrawatt and their install team for any solar projects. Very highly recommended!! Sales: Working with Scott was awesome. He didn't pressure me into solar, he just provided the facts. He also answered all of my questions and worked with me to design the best system for our needs. Project Management: Bianca has done a great job in getting all our permits and scheduling our job. She also answered all of my many questions. The whole team is fantastic!

We moved here in May of 2015. We bought a nice property that needed updating. So we did a full upgrade of the entire property. The main house is roughly 3,000 sq ft. and the guest house is 1000 sq ft. Our first energy bill was over 600 dollars. We decided to do some research on alternate energy sources. We contacted numerous Solar companies, and chose Delta Energy. From our first conversation we knew this was the company for us. The most professional people I have dealt with in a long time. They installed my system in only three days;was supposed to have taken six days. Now my energy bills are around 250.00 every month, and it is steadily going down. They come highly recommended from us. We are very satisfied...

I compared a half dozen quotes, and Radical was easily the cheapest per watt. The install was quick and painless, the panels look great on the house. Ted answered all my questions quickly and guided the process smoothly. I'll be recommending them to everyone who will listen.

I spent 1 1/2 years researching solar and how it may benefit me. I spoke to several companies who all provided me with their sales pitch. It wasn’t until I spoke with Ben Looney at Ion, did I feel knowledgeable enough to make the purchase. I changed my Solar plan twice, but that didn’t affect the level of service I received from Ben and the Ion team. I highly recommend using Ion for your solar needs.

Where there is no specific pricing information available for a brand then we have used state pricing data for that brand.
Solar panel manufacturer | Avg. cost per watt |

LG Solar | $2.63 |
SunPower | $2.76 |
Panasonic | $2.66 |
LONGi Solar | $2.13 |
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!
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:
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 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.
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.
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.
See what solar incentives are available in your area by using our solar panel calculator.
The cost of installing residential solar panels in Milfay 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.
The table below shows the data extracted from a real life quote delivered through the SolarReviews marketplace recently for a fairly typical home in Milfay.
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.
