The Cost of Installing a Residential Solar System:
A Comprehensive Guide

Understanding the Costs Associated with Solar System Installation

Solar energy is an excellent source of renewable energy that can be used to power homes and businesses. However, the cost of installing a solar system can vary significantly depending on various factors. In this article, we will provide a comprehensive guide to help you understand the costs associated with installing a residential solar system. We will also reference Sunergy Solutions LLC, a solar installation and service company servicing ME, NH, MA & RI, for more specific information on installation costs in those areas.

The cost of installing a residential solar system can be broken down into four main components: equipment, installation, permits, and incentives.


The cost of solar panels and other equipment is a significant factor in determining the overall cost of solar system installation. The number of solar panels needed depends on the size of your home, your energy consumption, and the amount of sunlight your property receives. Typically, solar panels cost around $2.50 to $3.50 per watt, which translates to approximately $12,500 to $17,500 for a 5-kilowatt system, the average size for a residential property.


The cost of installation can vary based on the complexity of the job and the type of roof you have. A professional solar installation company like Sunergy Solutions LLC will perform an on-site survey to determine the installation requirements, such as the type of mounting system and wiring necessary. Installation costs can range from $0.75 to $1.50 per watt, depending on various factors.


Permitting fees can vary depending on where you live. In general, the permit fee is approximately $500 to $1500. Solar installation companies like Sunergy Solutions LLC can take care of the permitting process for you, saving you time and hassle.


Incentives are available at the federal, state, and local levels to help offset the cost of solar system installation. The Federal Solar Tax Credit, also known as the Investment Tax Credit (ITC), offers a tax credit equal to 26% of the total cost of the solar system installation. In addition to the federal tax credit, there may be state and local incentives available to you. Solar installation companies like Sunergy Solutions LLC can help you navigate the incentives available in your area.

Understanding Solar System Financing Options

There are several financing options available for those who want to install a residential solar system. These include cash purchases, solar loans, leases, and power purchase agreements (PPAs).

Cash Purchases

Paying cash upfront is the most straightforward way to finance your solar system installation. However, this option may not be feasible for everyone.

Solar Loans

A solar loan is a great option for those who cannot afford to pay upfront but want to own their solar system eventually. The loan typically has a fixed interest rate and term length.


A solar lease allows you to use the solar system without owning it. You pay a monthly fee to the solar installation company, which owns and maintains the system. However, you will not be eligible for any tax incentives.


A PPA allows you to purchase the power generated by the solar system rather than the system itself. You pay a fixed rate per kilowatt-hour of electricity generated, which is typically lower than what you would pay for electricity from the grid.

Choosing the Right Solar Installation Company

Choosing the right solar installation company is critical to ensure that your solar system is installed correctly and efficiently. Sunergy Solutions LLC is an excellent choice for those in ME, NH, MA & RI, as they offer high-quality solar installations and excellent customer service.

In conclusion, the cost of installing a residential solar system can vary depending on various factors, such as the size of your home, energy consumption, location, and available incentives. However, with proper financing and the right solar installation company, solar system installation can be a smart investment that can save you money in the long run while reducing your carbon footprint.
