What Affects the Cost of a Solar Panel System?

The cost of solar panels can vary widely from one brand to the next. What exactly affects the cost of solar panels? As you shop, you’ll notice the following characteristics play a role in the price you see attached to each panel.

  • Type of silicon cell: The two most common types of silicon cells you’ll see when shopping for solar panels include monocrystalline silicon and polycrystalline silicon. Polycrystalline solar panels have lower overall efficiency rates when compared to mono panels, which is why they come with a lower price tag.
  • Your installation: The method of installation that your solar panel kit requires also influences the total amount that you’ll spend on the system. Most solar systems are roof mounts, which are relatively easy to install without much extra effort or components. However, some systems require ground mounts, which may come with an additional labor charge not included in the price of the system itself.
  • Where your home is located: While it’s no secret that many states have instituted tax incentives to help encourage homeowners to take advantage of the benefits that solar power has to offer, you may not know that your location also influences price in terms of system setup. For example, if you live in an area that doesn’t receive as much direct sunlight, you might need to install more panels or invest in a system with a higher efficiency rating to cover a significant percentage of your energy needs. As is the case with most industries, market conditions also vary from one zip code to another, which will change the price that you’ll pay for your solar system.
  • Your battery: If you live in an area that doesn’t receive consistent sunlight, you might want to install a solar battery to conserve power when bright light is available. Adding a solar battery to your system will add another $10,000 to the total price of the system. The good news is that most states also extend solar rebates and tax incentives to solar battery investments and chargers as well — so this cost isn’t as hefty as it may seem at first.

Our Top Pick: The Cheapest Solar Panel of 2022

If you’re looking for cost-effective solar panels, be sure to first think about your energy needs. When you search for solar panel systems by affordability, you’ll notice that the panels that cost the least also have the lowest overall panel efficiency. This lower efficiency indicates that your residential solar panels are not able to turn as much sunlight into energy as other systems on the market. While this might not seem like a big deal, it also means that you can rely on your solar panel system to cover a lower percentage of your home’s energy usage, paying itself back in more time.

Cheap Solar Panel FAQs

What is the difference between cheap solar panels and expensive solar panels?

The main difference between cheap solar panels and expensive solar panels is the functionality of each option. More expensive solar panels (like those offered by SunPower) have efficiency ratings over 20%, while more affordable solar service providers offer panels with lower efficiency ratings. This means that, while low-cost solar panels still convert sunlight to usable energy for your home, they create less energy over time than more efficient models. More expensive models also tend to have a longer lifespan when compared to low-cost models.

What are the advantages of cheap solar panels?

There are plenty of benefits that come with choosing cheap solar panels. Obviously, the low price of these panels makes them more accessible for more homeowners. Previously, solar panel installation and financing routinely cost upwards of $5,000. Today’s solar panel prices are much more affordable — depending on where you live and the brand you choose, you could pay less than $150 per panel. When you consider the lower cost manufacturing and installation companies are now charging combined with the many tax incentives you can claim just for choosing solar power, cheap solar panels are now more affordable than ever before.

How much electricity can cheap solar panels produce?

The answer to this question will vary depending on the strength of your solar panels as well as the array you lay out on your roof to collect sunlight. An average low-cost solar panel display is around five kilowatts (kW), taking up about 400 feet of space and producing 350 to 850-kilowatt hours per month. To put this number in perspective, the average household uses about 900-kilowatt hours per month. This means that even when operating a lower-cost solar panel system, it’s very possible to cover a major percentage of your home’s energy usage through the power of solar energy.

How much does it cost to install solar panels?

The price you’ll pay to install your residential solar system will vary largely depending on the number of kilowatts you decide to install. The kilowatt size of your system determines how much power the solar panels can generate and convert to usable electricity for your home. As a general rule, you’ll pay less per kilowatt as the kilowatt size of your unit increases. The price you’ll pay per watt will range from $2.60 for larger kilowatt systems to $3.25 for smaller or more efficient units.

House Method’s Solar Companies Rating Methodology

At House Method, transparency and trust are our most important values for the reader. That’s why we took the time to create an objective rating system and score each solar energy company/service according to our methodology.

Our research team dug deep into the fine print of contracts, combed through more than one hundred customer reviews, and thoroughly investigated all of each solar energy company’s services, costs, and products. We’ve done the homework for you by researching nearly all of the solar energy companies on the market so you can have the information you need to make the best choice for your home.

We developed a formula to objectively determine the best solar energy companies and give each a score out of 100 based on the following criteria:

Plan Options (30): Do they provide a variety of plan options? We looked at the number of plans each solar energy company offered and the flexibility of adjusting the plan.

Services offered (20): How many services are offered in each plan? We looked at whether the company manufactures its own solar panels, whether it contracts out installation, and what additional products each company offers.

Trust (10): What do customers say after their solar panels are installed? Does this company offer a guarantee? We considered how satisfied customers are post-service if the company does what it says it will, BBB accreditation, and service guarantees.

Prices (10): How reasonable are the costs of the plan or service in comparison to the industry average? We compared the costs of each company to competitors that offer the same solar energy services.

Unique perks (10): Does the company offer discounts or special services such as financial incentives, rebates, or a useful mobile app? We looked for extras each company offers that set them apart from the competition.

Customer Service (10): How is the customer experience when contacting the company? We considered the speed of response, weekend/holiday availability, and ease of communication through phone calls, email, and online chat functions.

Nationwide availability (10): How many states does the company offer its services? Companies that operate nationally and in all zip codes are favored over those with limited availability.
