If you’re wondering where to get cheap solar panels, there are a number of ways to evaluate the expense of solar based on location.

Regardless of your zip code, if you do the research and spend some time working with your installer it’s possible to find a relatively cheap solar offer anywhere in the United States.

It is worth noting that cheaper solar panels may vary in quality when compared to more expensive options. This is especially true when considering long term costs vs. upfront costs.

However, there are many products that are affordable and still provide good value for customers who value economy over other selling points. 

In 2022, the average price for a solar power system is around $2.77 per watt. There’s no doubt that, regardless of how you finance your solar panel system, going solar will be an economical process with strong returns.

Will solar panels get cheaper? What to expect for solar energy prices

According to the International Energy Agency (IEA), in 2020 solar was the cheapest electricity source in history. Solar energy prices have followed a downward slope similar to those of most other renewable energy sources, and as technology improves and solar energy becomes more accessible, the prices will drop further. The Department of Energy is aiming to cut solar energy costs by 60 percent in the next ten years by providing $128 million in funding to research and development efforts aimed at making solar more efficient, deployable, and affordable for people across demographics.. 

With all of this in mind, finding the lowest possible price tag for your solar panel installation might sound like the best way to save money when you go solar. However, cutting your purchase price is only one way to maximize the cash back in your pocket. You could make your purchase entirely focused on cutting costs in the short term but the payback period of your solar panel system might take twice as long and your panels may never earn the return you expected.

Long-term benefits outweigh high upfront costs

While cheap solar panels and DIY solar panel kits can be a good value, they don’t always save you the most money over the long term. Therefore, it’s a good idea to think about long-term value rather than just searching for the most discounted solar price and installation. At the end of the day, solar is about long-term sustainable savings and not about finding a “steal.”

Solar is a big investment: if you want to maximize your long-term solar savings, it’s important to take this into consideration. Not all solar panels are created equal – a more expensive panel might have a better warranty or be able to generate more electricity than a low-cost option. You may hear suggestions to order the cheapest solar cells available on sites like eBay but in taking that approach, you will lose out on quality. The real benefit of solar energy lies in its ability to convert sunlight into available power effectively. 

Luckily, you don’t need to pay serious cash out of pocket to get the best solar panel deal. With most solar loans today, you don’t have to pay any money down. In many cases, your new monthly solar loan payments will be lower than your old electricity bill costs, so you’ll start seeing the financial benefits of solar as soon as you install. Here’s some advice for the modern day solar shopper:
