If you’re looking for every possible way to cut the upfront cost of solar panels, you’re not alone. Switching to solar can lead to substantial savings on electricity bills, but the initial five-figure bill can feel like a bombshell. 

Fortunately, you don’t have to sacrifice performance for price these days. Solar technology is no longer novel, and plenty of companies produce quality, affordable solar panels. While you probably won’t get it all with cheaper solar panels (price, efficiency, a low temperature coefficient, and an outstanding warranty), you should end up with a system that fits your needs and makes financial sense in the short and long term. 

Based on our latest Intel Report, we’ve compiled a list of the best cheap solar panels that are as reputable as they are affordable.

Key Takeaways

  • AXITEC, Jinko Solar, LONGi Solar, REC Group, and QCELLS are our top picks for the best cheap solar panels based on their price per watt ($/W) and performance. 

  • Solar panel affordability continues to increase thanks to falling prices, incentives, rebates, and flexible financing options. 

  • The solar panel with the cheapest price tag may not be the most cost-effective option in the long term. Consider efficiency, performance, and warranties when comparing your options. 

  • Your payback period may be longer if you shop for solar panels with the lowest price tag.

Many of the EnergySage Buyer's Guide's most affordable solar panel brands also produce some of the best solar panels. Here are our top picks for the best cheap solar panels based on the average cost per watt and performance.

AXITEC: Our cheapest solar panel pick

At just $2.36 per watt, AXITEC offers the cheapest solar panels per watt on our list. The German manufacturer offers average warranties and isn’t a top performer in terms of performance or resiliency, but AXITEC panels can be a great way to go solar on a budget.

Our product pick: AXITEC AXIblackbipremium XXL HC 400 W

Jinko Solar: Reliable and resilient 

Jinko Solar made our 2024 list of best solar panels for “Best performance per penny,” securing its position as not only one of the best cheap solar panels but a top contender overall. Jinko is a highly reliable solar panel at a well-below-average price. It’s not the most efficient panel on our list, but if you’re looking for a quality panel that won’t break the bank, Jinko Solar is a solid option. 

Our product pick: Jinko Solar JKM410M-72H-V 410 W

LONGi Solar: Highly efficient and cost-effective 

LONGi Solar produces high-efficiency PERC solar cells at an incredible price. While other brands offer better warranties and temperature coefficients, LONGi solar panels’ efficiency ratings are up there with some of the top brands on the market.  If you’re trying to go solar on a budget but aren’t willing to sacrifice efficiency, LONGi solar panels are a great solution. 

Our product pick: LONGi Solar LR5-54HPB-410M 410 W

REC Group: Premium solar panel at a below average price

REC Group solar panels are the most frequently quoted brand on EnergySage and, based on our latest Intel Report, the least expensive (when paired with the Solar Edge inverter) of our top brands. REC Group isn’t the cheapest solar panel available, but unlike some other brands on this list, they don’t just compete for affordability. REC Group produces efficient, high-performance solar panels comparable to premium brands like SunPower and Maxeon—but about 19% cheaper. 

Our product pick: REC Group Alpha Pure-R 400

QCELLS: Pricier, but great performance 

QCELLS solar panels are the most expensive on our list but still among the least expensive and most popular solar panels quoted on EnergySage. We analyzed the price difference of some of the most frequently quoted products on the Marketplace and found that QCELLS solar panels (when paired with the Enphase inverter) are just 1.1% more expensive than the cheapest equipment pairing. Like REC Group, QCELLS is a top solar panel manufacturer that offers a great bang for your buck. 

Our product pick: Q CELLS Q.PEAK DUO BLK ML-G10+ 400 W

Cheaper solar panels can be worth it, but it depends on your needs. Are you looking to install the most efficient solar panel system possible? In that case, going with a more expensive but highly efficient panel from a brand like SunPower may be worth it. But if you’re going solar on a budget, plenty of affordable options provide excellent value. Either way, it’s important to consider your options' long-term vs. upfront costs to better understand the true cost-effectiveness of a solar panel system.

Evaluate solar panels’ long-term value, not just the sticker price

Just because a product is cheaper doesn’t mean it’s the most cost-effective option; just because a product is more expensive doesn’t mean it’s necessarily the most valuable. To understand a solar panel’s long-term value, consider its efficiency, performance, and warranties in addition to the upfront cost. 

Generally, solar energy’s value lies in effectively converting sunlight into available power, which high-efficiency panels do best. Finding the lowest possible price tag for your solar panel installation might sound like the best way to save money when you go solar, but the payback period of your solar panel system might take twice as long, and your panels may never earn the return you expected. 

Solar is already pretty affordable

In 2024, the average cost of solar panels is around $2.86/W before incentives. Between falling prices, incentives and rebates, and flexible financing options, you likely won’t need to pay serious cash out of pocket to get the best solar panel deal. The federal solar tax credit alone decreases the cost of solar by 30%, and most solar loans today don’t require you to pay any money down.

Solar energy prices fluctuate as economics in any industry do, but the general trend remains downward. After two years of steady increases in solar prices on EnergySage, our median price per watt decreased for the first time since 2021 during the second half of 2023. 

As technology improves and solar energy becomes more accessible, prices will drop further. The Department of Energy aims to cut solar energy costs by 60% by 2030 by providing $128 million in funding to research and development efforts to make solar energy more efficient, deployable, and affordable for people across demographics.

Here are some key takeaways from our pricing data:

  • Installing solar panels in the United States will cost about $22,022. Other home electrical upgrades, such as a solar battery or an EV charger, will also increase your overall cost.

  • You can save about $42,000 over 25 years by installing solar. The lifetime savings of your solar panel installation depends on where you live and the cost of electricity. 

  • A bigger solar panel system usually means a better solar bargain. While solar panel system wattages vary based on several factors, choosing a larger size will typically lower your cost per watt.
