*Prices are shown after applying the 30% federal tax credit.
As of Apr 2024, the average cost of solar panels in Pound is $2.62 per watt making a typical 6000 watt (6 kW) solar system $11,021 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.

I recently had a photovoltaic solar energy system installed on my roof by All Energy Solar, and overall, I am very pleased with the experience. From the start, the company's sales team made a great impression by being personable, professional, and thorough in answering all my questions. Once I signed the contract, I was assigned a dedicated customer service representative, Carlo Maloni, who kept me updated throughout the approval and installation process. His communication was excellent, and he made sure to keep me informed at each step. The interconnection approval and installation process went smoothly, despite some challenges due to the complex setup in my duplex home. The team encountered obstacles related to my neighbor's pre-existing solar array on their side of the roof, and the installation team had to develop creative solutions to work around the neighbor's equipment. Despite these hurdles, the installation team was thorough, resourceful, and respectful of my neighbor's space. While there were some minor delays due to these complexities, the team handled everything professionally and kept me informed about their progress. The timeline from "signed contract" to "first watts produced" was just under 6 months. After the installation was completed, the company continued to provide excellent follow-up service. They helped me set up the Enphase Enlighten app for real-time monitoring of my system's energy production and guided me through the process of participating in the residential energy credit (REC) market. I experienced a minor issue with the system's monitoring, but the company resolved it within hours of my call, which I greatly appreciated. In conclusion, I am very happy with the service provided by All Energy Solar. Their team was professional, knowledgeable, and attentive throughout the process. I highly recommend them for anyone considering a solar energy system installation in Boston, MA or the surrounding area.

I was very happy with Certasun and their work in designing and installing my solar power system. Questions I had were answered very quickly. It took less than a day for the installation and then less than 2 weeks to have the system inspected and approved and then have the power company comvert my account to net metering. Certasun handled all of the permitting process and all interactions with the power company and it all went smoothly. Overall it was a very good experience with Certasun.

We picked Arch to install our solar after shopping around quite a bit. We choose them because they (Stanley specifically) answered my many questions with detail, patience, and was very knowledgeable. There was no pressure like with other companies we got quotes from. Crew was efficient and courteous during installation. There was a small problem with our internet setup connecting with the monitoring system when it was turned on but they came out quickly & had it resolved soon.

We are extremely impressed with Energy Concepts. They designed and installed a residential solar system that has been functioning perfectly. The system (now in operation for a full year) has exceeded all expectations. Throughout the design and installation process Energy Concepts was consistently professional and they have remained responsive to any questions well after installation. Russel and Claudia represent what we all want from a business, honest and hardworking people who strive for excellence. We thank Energy Concepts for a great experience and give them our highest possible recommendation.

If I could give more than 5 stars I would. These guys were so patient with us. It took us several years before we were ready to commit to such a large expenditure. They told us what they thought would work, not just what we wanted to hear. They installed the system in early December of 2013, during an early, frigid, snowy time. Everything was just what they said it would be. We are now making more electricity than we use! (Or should I say, the sun is making the energy, all we do is smile when we see the sun shining!

We had a home installation that went very smoothly. Mike from Full Spectrum assisted us with applying for tax credits and in our hookup with the local power company. Things were seamless and we are currently up and fully functional. Staff was friendly and efficient and costs were as predicted. We are very happy with the results so far. Installation was in late December so we are about 3 months out.

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 |
---|---|
Canadian Solar | $2.45 |
LG Solar | $2.91 |
SunPower | $3.06 |
Panasonic | $2.95 |
LONGi Solar | $2.36 |
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 Pound 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 Pound.
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.
System information | Value |

System Size (for 100% usage offset) | 10.26 kW |
Annual power generation | 12,037 kWh |
Pay-back time (assuming Cash purchase) | 10.4 Years |

Gross cost | $25,360 |
Total Upfront Incentives and Rebates | -$7,594 |
Net Cost of System after rebated and incentives | $17,766 |
Total Cost of Utility Power Avoided over 25 years | $54,553 |
