The good news is that solar panel costs have fallen faster than ever. Thanks to falling energy prices, and state incentives, homeowners can see a return on their investment in less than ten years. Several factors affect overall solar system costs, including hardware and soft costs such as labor and permitting. Your home’s electrical demand, panel choice, and solar energy production potential are key factors to consider.

Cost of Materials

The upfront cost of a solar system depends on several factors, including purchase options, wattage, and location. Customers can pay in one lump sum, take out a loan or lease, or sign a Power Purchase Agreement (PPA). The option that best fits your home will affect your long-term solar panel cost. Purchasing solar panels in bulk typically reduces the price per watt. This is because the more solar panels you buy, the cheaper it is to install.

Solar panel prices vary by brand, with some offering higher quality and lower maintenance costs. For example, monocrystalline solar panels—which are made of high-purity silicon cut into wafer-like shapes—cost around $1 per watt at wholesale pricing. Polycrystalline solar panels, made of melted and molded silicon, offer lower pricing but less energy production than mono panels. They also occupy more space and are better suited for RVs or sheds. In addition to the solar panel price, the total cost of a solar energy system includes installation and labor, which can vary based on the system’s size, location, and necessary permits or inspections. The type of solar system chosen, such as grid-tied, grid-tied plus storage, or off-grid, can also impact the price. For example, homeowners in hotter climates may require a more extensive system than those in cooler regions.


Depending on your location, solar panel prices may differ. The price of the panels themselves is the primary variable, but soft costs are also involved in the installation process, such as labor and permits. Solar installers are generally willing to negotiate the price of the system. They’ll also consider the type of energy your household uses and how much sun you receive. This information will determine the size of your solar system, which in turn impacts your price per watt. The average cost of solar panels can range from around $10,000 to $30,000 for an American household. The actual cost will depend on the number of solar panels needed to offset your energy usage and the system’s efficiency and life expectancy. Generally, homeowners will want to choose the highest-efficiency solar panels available. This will increase the lifespan of their panels and reduce overall system costs due to lower energy production costs. When calculating your solar savings, it is essential to factor in all upfront costs, including any rebates, tax credits, or grants received. In addition, you’ll need to estimate your annual energy bill to calculate your overall savings over time. It’s helpful to use a tool such as an online calculator to help you make these calculations.


You can sigh in relief when your solar panels are installed, but that doesn’t mean they’re in the clear. Like any other investment, your solar system requires regular cleaning and inspections to maintain peak performance. Fortunately, you can reduce these costs by implementing advanced technology that allows you to monitor your solar panels remotely and alerts you to issues before they become costly repairs. Solar panel maintenance expenses vary depending on a few factors. First, your location will influence how much it costs to clean and inspect your solar panels. For example, there may be additional travel expenses if you live in a rural area. The number of panels and how long it’s been since their last cleaning will also affect your maintenance costs. The best way to estimate the maintenance cost is to ask your solar contractor about their fees. They should provide a comprehensive list of services and prices for each. This will give you an idea of what to expect for routine maintenance and repair and replacement costs. While it is not always possible, it’s best to replace broken or damaged panels as soon as possible. Not only will this help you avoid wasting energy, but it will also ensure that your solar system produces the most energy possible.


Solar panels may require repairs discovered through annual inspection or monitoring technology. Prompt repair is necessary to avoid efficiency loss. The cost of repairs varies based on the severity of the issue. For example, if your solar panels have a cracked frame or broken glass panel, you’ll likely need to replace the entire unit. This can add up to a significant amount of money, but ensuring your solar energy system continues to function at peak performance is necessary. The size and location of your solar energy system can also impact solar panel repair costs. For example, rooftop solar panels can be challenging to access and are more expensive to repair than ground-mounted systems. Additionally, the type of solar energy system you have (including an inverter) also impacts repair costs. Homeowners typically rely on professionals to repair their solar energy systems. These experts can conduct thorough tests to identify issues with solar panels and complete repair work quickly. They can also provide valuable advice on the condition of the panels and recommend future maintenance or repairs.
