Key takeaways


olar power, among all other renewable energy sources, has been making significant strides over the past few years. Whether you're a homeowner interested in reducing electricity costs or an entrepreneur aiming for a greener business operation, solar energy presents an appealing option.

Now, let's talk about one of the most important aspects of going solar: the solar installation cost. What investments are needed to transition to this renewable power source? This article will serve as a guide, providing insight into the many factors contributing to the total costs of a solar setup.

Solar System Expenses: How Much Does a PV Panel Cost

Panel Types and Technologies

When discussing solar installation cost, panel types and technologies are crucial to consider. There are three main types of solar panels:

  1. Monocrystalline panels: These are the most efficient type of solar modules but also come at the highest cost per unit. They are made from a single, high-purity crystal structure, allowing for a higher rate of energy conversion. Monocrystalline panels also tend to have a sleek black design, which many homeowners find visually appealing. If space is a limitation, or if you're aiming for maximum efficiency per unit regardless of the cost, monocrystalline panels might be the best choice.
  1. Polycrystalline panels: These modules are made from multiple silicon fragments melted together, which results in a lower efficiency compared to monocrystalline panels. However, they also have a lower cost, making them a popular choice for those looking to spend less per each photovoltaic (PV) unit. If you have ample roof space and are looking for a cost-effective solar solution, polycrystalline panels might be suitable for you.
  1. Thin-film panels: These are often considered to be low cost and the least efficient type of solar panels, however, it’s not the case anymore. Nowadays some thin-film panels can even compete with monocrystalline modules with some of the models reaching efficiencies up to 18%. They are also easy to produce and have a uniform appearance, which can be an aesthetic advantage. Due to the slightly lower efficiency, they still require more space than top-performing options. If cost per module is your primary concern and you have plenty of space, thin-film panels could be an option to consider.

Each panel type contributes differently to the solar installation cost, so the choice should be well thought through.

Warranty and Longevity

Quality panels come with lengthy warranties which show how much trust the manufacturer has in its product. While more performant options might increase the solar electric panels cost, a longer warranty can offer peace of mind and ultimately result in savings over the long term.

Quantity and Solar Setup Size

The number of panels required will greatly influence the cost of solar installation. A larger 10 kW setup will obviously require more panels and associated equipment, which increases the overall solar system installation cost.

Geographic Location and Solar Potential

The location of your house can also affect the solar installation cost. Regions with higher solar irradiance can achieve higher energy output with the same setup size, hence requiring fewer panels. For example, a 5 kW installation might generate about 5,000 kWh per year, while in sunny California, the same 5 kW system could produce over 7,000 kWh. Keep in mind this is just an estimate and your specific circumstances will change the actual output.

Solar Incentives and Rebates

In many regions, governmental incentives and rebates can significantly reduce the solar panel installation price. Be sure to check what's available in your area.

Costs Breakdown: Understanding Solar Panel Setup Expenses

Components Included in the Total Cost

The total solar system installation cost includes not just the price of the panels but also several other elements, let’s explore.

Panel Mounting Equipment and Racking

These components securely attach the panels to whichever site you choose. They are crucial whether you’re setting up a small 2 kW system or a large 30 kW ground installation. The complexity of the architecture and roof material will influence the mounting equipment cost per panel.

Inverters and Other Components

These devices convert the direct current (DC) electricity produced by the solar panels into alternating current (AC) electricity that can be used in your house or business.

Wiring and Connections

These provide the physical connections needed for your PV system to function. It doesn’t matter if you have a small 1 kW system or a large one, the system won’t work safely without secure connections.

Balance of System (BOS) Components

These include all the remaining parts of the solar system, such as switches, fuses, and meters.

Labor and PV Panel Installation Costs

This involves the cost of solar professionals setting up and connecting your solar power system. Factors such as the complexity of the setup and the installer's experience can influence these costs.

Taking all of this into consideration can help you estimate the solar installed cost per kw more accurately.

Cost Comparison: 5kW Monocrystalline vs. Polycrystalline

Monocrystalline vs. Polycrystalline Solar Panels
Monocrystalline vs. Polycrystalline Solar Panels

Let’s venture further into our quest for the best solar installation cost and take a look at a system comparison to better illustrate solar electric panels cost and performance differences.

Average Market Rates per Watt

A monocrystalline solar panel’s cost per watt falls within the $1 to $1.5 range. Polycrystalline solar panels cost a bit less, hovering around $0.9 to $1 per watt. However, it is essential to remember that these are raw panel price estimates and do not reflect the total solar installation cost.

Panel Performance and Efficiency Comparison

Efficiency matters. The higher the solar panel efficiency, the less space you'll need per each kW you acquire. For those with less space, monocrystalline panels, which typically deliver efficiencies of 15-20%, can be an excellent choice. Polycrystalline panels offer slightly less efficiency, typically in the range of 13-16%, but come at a lower cost.

How to Choose Between the Two?

When choosing between these two types of solar panels, consider your available space, your energy needs, and the solar electric panels cost. If you need a larger 7 kW setup and your roof space is limited, the higher-cost monocrystalline panels might be worth the investment. If you have ample space and are looking to spend less per each PV module, the lower-cost polycrystalline panels could be your ideal fit.

Comparison Results: PV Panel Cost

Taking everything into consideration, a 5 kw monocrystalline solar system installation cost is around $16,000. This price includes the panels at $1.25 per watt, labor, the electrical system, and the rest of the components. A 5 kW polycrystalline setup of the same size would cost approximately $14,500. Keep in mind that these are just estimates, and the best way to find out the precise solar installation cost that suits your specific needs is by contacting the company of choice directly.

Financing and Incentive Options

Going solar doesn't necessarily require a large upfront cost. Multiple financing and incentive options can significantly reduce your out-of-pocket solar installation cost.

Solar Loans and Financing Programs

Several banks and financial institutions offer solar loans per setup, essentially allowing you to swap your energy bill for a loan payment, often with no upfront cost. These loans enable you to own the solar setup, whether it’s a 3 kW residential system or a 50 kW commercial one, and reap the full benefits of solar power.

Federal and State Incentives

Government incentives can substantially lower the cost of solar installation. The federal government, for example, offers an Investment Tax Credit (ITC) of 30% of the system's cost. State incentives also exist, which can include additional tax credits, rebates, and performance payments.

Solar Renewable Energy Certificates and Clean Energy Purchase Contracts

SRECs are tradable commodities that you earn per each kilowatt-hour of solar energy your system produces and typically apply to 5 kW to 10 kW setups. In some states, utilities buy these certificates at a set cost to meet mandated renewable energy generation targets. Power Purchase Agreements or PPAs are agreements where a third party owns the system, and you pay for the energy it produces at a predetermined cost which is usually lower than the average electricity cost.

Solar Panel Payback Period and ROI: How Much Does it Save You?

A well-planned solar setup per se is not just an environmentally friendly choice but a smart financial investment as well. Let’s find out if the initial costs are worth it long-term.

Definition of Payback Period and ROI

The payback period refers to the length of time it takes for the savings from your PV setup to equal the total cost of the system. ROI is a measure of the profitability of your investment, calculated by dividing the net profit by the total system costs.

Factors Influencing the Payback Period

The payback period for a solar setup is determined by several factors: the system's cost, the amount of electricity it produces (and thus how much it reduces your energy costs), and any earnings from SRECs or other incentives.

Calculation Explanation of the Payback Period and ROI

To calculate the payback period, divide the total solar installation cost by the annual financial benefits (energy bill savings plus any incentive earnings). ROI can be calculated by dividing the net benefit (total benefit - total cost) over the lifetime of the system by the total costs and then multiplying by 100 to get a percentage.

Solar Numbers: How Much Does it Save?

A solar system can cover all your electricity needs and bring profit long-term if it is planned correctly. To illustrate, let’s get back to that 5 kW setup and analyze some details. First off, this 5 kW setup will cost you around $11,200 per system with the 30% ITC. Let’s say you consume around 9500 kWh per year and the system covers 6,500 kWh out of that which translates to roughly $1,500 of savings per year (23 cents per kWh). In that case, the estimated payback period will be around 7 years and the ROI will be 230% over the system’s lifespan of 25 years. Pretty impressive, isn’t it?\

Additional Cost Factors to Consider

Permitting and Inspection Fees per Setup

Permitting and inspection costs vary by location, but they typically range from $100 to $500 per setup. Be sure to check with your local city or county building department or permitting office to get more precise estimates.

Grid Connection and Net Metering

Most grid-tied solar systems require a fee to connect to the utility grid. In addition, some utilities offer net metering, where you can sell excess energy back to the grid, which can help offset the solar system costs.

Monitoring and Maintenance Costs

Solar panel systems require little maintenance, but monitoring systems can help ensure they are working correctly. These can range from $250 to $500 per system, but they can also be included with the inverter. Periodic cleaning and occasional inverter replacement (every 10-15 years) are the primary maintenance costs.

The cost of cleaning solar panels and batteries varies based on factors like size, accessibility, and frequency. Generally, it ranges from $100 to $500 per cleaning session.

Upgrading and Expanding the PV Panel Setup

Consider your future kW needs. If you expect to increase your energy usage in the future (for example, by buying an electric vehicle or expanding your home), you might want to add 1 or 2 kW for this increased usage, which will increase the total solar system installation cost, but will spare you the trouble later.

Tips to Reduce Solar Installation Cost

Reducing a solar installation cost may seem challenging per se, but it's not impossible. There are several strategies to keep in mind that can help bring down the costs significantly.

Choose the Right Solar Panel Setup Size

Choosing the right system size is critical to avoid unnecessary costs. For example, if your needs are modest, you might do fine with a small 3 kW system. However, if you have many energy-consuming appliances, a 5-7 kW setup would suit you better. Consulting with a professional can help you assess your energy needs accurately and avoid paying for more than you need.

Take Advantage of Incentives and Rebates

Federal, state, and local incentives can significantly reduce the overall solar panel system cost. Keep abreast of the latest programs to be able to take full advantage of these cost-saving opportunities.

Consider DIY Solar Mounting

For those with the required technical expertise, mounting the solar panels themselves can drop the solar installation cost altogether as there is no need to pay for labor, especially for small 1 – 2 kW systems. However, keep in mind that this is a complex task and is not recommended for everyone.

Shop Around

Getting multiple quotes from different solar companies allows you to compare prices and negotiate better deals. This competitive bidding process can help reduce your solar installation cost.
