What to Consider When Choosing One of the Best Solar Companies in Virginia
There’s a lot of information to process when considering a solar panel installation project. Here are the most important factors to keep in mind when preparing for a solar panel installation and vetting a solar company.
Home Location and Roof Type
When a homeowner considers installing a solar panel system, the first thing they will want to think about is their house, specifically the orientation of their roof, its pitch, and its material. For maximum sunlight exposure throughout the year, it’s advisable to install solar panels on a south-facing roof in the northern hemisphere, as the sun follows a slightly southern path due to the earth’s tilt. Southeast and southwest orientations are also viable options since they still capture some of the sun’s southerly path. However, panels installed on other roof orientations may not generate power as efficiently.
The optimal angle for mounting solar panels is between 30 and 45 degrees, but for flat roofs, panels can be mounted on brackets that tilt them up to 30 degrees. While panels can be mounted on steep roofs, they may not generate enough power for a home to become energy independent. Any roof material can support a solar panel system, but certain types are easier to work with. Composite shingles are resilient and can withstand the installation process well, while standing seams on metal roofs reduce the need for drilling and modifications. Installing a solar panel system on a tile roof can be challenging due to the irregularities of each tile, and it may require more labor and cost.
Type of Panels and Efficiency
Solar panels that are commonly used for powering homes are either monocrystalline or polycrystalline. Monocrystalline panels are more efficient at converting sunlight into usable electricity but come with a higher price tag. On the other hand, polycrystalline panels are more affordable but less efficient at producing power. One can distinguish between the two types of panels by their color: monocrystalline panels are black, while polycrystalline panels are blue. Choosing the right panel will depend on a homeowner’s budget and power production goals. A skilled solar installer in Virginia can assist in making the best decision.
It is important to note that the efficiency of a solar cell is not equivalent to the efficiency of a panel. A solar cell is a component of a solar panel, and it can have an efficiency of over 40 percent. However, a panel’s efficiency is lower. Monocrystalline panels have a maximum efficiency of about 23 percent, while polycrystalline panels reach approximately 16 percent. Although researchers at the National Renewable Energy Laboratory have developed solar panels with an efficiency of almost 40 percent, this technology is not yet publicly available.
Thin-film solar panels are another type to consider. These panels are thin, lightweight, and flexible, but they are less efficient than polycrystalline panels. Thin-film panels also have a shorter lifespan of 10 to 20 years compared to the 25-year-plus lifespan of monocrystalline and polycrystalline panels. Because of their lower efficiency, more thin-film panels would be required to power a home fully, and most roofs do not have the necessary space. However, thin-film panels can be used as supplemental power sources and can be useful for homes with irregularly shaped roofs that may not be suitable for traditional panels.
On-Grid vs. Off-Grid
When installing a solar system, homeowners must decide whether to connect their home to the local power grid or not. A solar panel array connected to the municipal grid is called a grid-tied or on-grid home. Grid-tied homes can still draw power from the utility during times when the solar system is not producing enough electricity. However, the home will still lose power during a local power outage.
Off-grid homes, on the other hand, are entirely energy independent, generating enough energy for all the home’s power needs. These systems use solar batteries to store excess energy for use during the night or on cloudy days, and they rely on solar charge controllers to regulate energy flow. Off-grid homes are not affected by local outages but will experience a power outage if their batteries are depleted and the panels are not producing enough electricity. The suitability of off-grid solar systems varies by region and home, and a professional solar installer can assist homeowners in making a well-informed decision.
Financing, Rebates, and Tax Incentives
The average cost to install a solar system in Virginia is about $15,000, and not every homeowner has that lump sum of money readily available. The financing options available to a homeowner will, in part, depend on where they live. In Virginia, homeowners have three financing options: a solar loan, a solar lease, or a power purchase agreement (PPA).
- Solar loan: A homeowner borrows money from a lender or solar developer to purchase and install a solar system. In this situation, the homeowner owns the system, but it’s still subject to a lien or lender security interest. However, not every homeowner will be eligible for a loan, and the homeowner is totally responsible for any maintenance costs.
- Solar lease: A homeowner enters into a contract with a solar leasing company or developer. The homeowner makes regular payments and, in exchange, receives the energy the panels produce. Some contracts may require the homeowner to make a down payment. At first, the lease payments are often less than the value of the power being generated. However, payments for solar leases often escalate as time goes on. Eventually, the cost of the payment may be greater than the value of the power being produced. This option is attractive because there’s little to no up-front cost and the solar developer is in charge of any maintenance. However, homeowners may not be eligible for tax incentives, and there may be restrictions if a homeowner wants to add new construction (e.g., if the homeowner wanted to build a new addition that would block the panels from getting light).
- Power purchase agreement (PPA): A PPA is similar to a solar lease. The solar company buys and installs the solar system, and the homeowner pays the company per kilowatt-hour (kWh) for the energy that’s produced. A homeowner typically pays less for the solar energy than they would buying the equivalent amount from the utility. However, the PPA rate generally increases over time. The advantages and disadvantages are similar to those of a solar lease.
Solar panel installation in Virginia can be made even more affordable with federal and state tax incentives.
- Federal investment tax credit (ITC): For solar systems installed between 2023 and 2032, homeowners are eligible for a 30 percent tax credit. So, for example, if the solar system cost $10,000, the homeowner can obtain a $3,000 reduction on their federal income taxes. Solar leases and PPAs do not qualify for this credit.
- Solar sales tax exemption: Home solar systems are not subject to Virginia’s sales and use tax.
- Property tax exemption: As of January 1, 2023, the installation of solar panels does not raise a homeowner’s property taxes in Virginia.
- Virginia Clean Economy Act: Virginia has a program through the Virginia Clean Economy Act (VCEA) that helps homeowners get reimbursed for energy production. For each megawatt-hour of solar energy produced, a homeowner will receive a solar renewable energy certificate (SREC), which they can sell to utility companies.
Similar to other types of home improvement projects, labor warranties are commonly provided with solar panel installations to address any issues that result from the installation process. These warranties can typically range from 10 to 25 years. In addition to labor warranties, the solar panels will also come with a manufacturer warranty, which can usually last up to 25 years. Moreover, several solar companies operating in Virginia offer power-production guarantees, which ensure that the solar system will produce a certain level of energy for the entire guarantee term, often ranging from 20 to 25 years.
Solar companies that provide various customer support options typically receive higher satisfaction ratings, as customers find it easier to contact representatives with their questions and concerns. While phone support is the norm, some companies may have longer wait times to speak with a live person. For this reason, some customers prefer to email the company, which also provides a written record of the conversation.

Before You Work With One of the Best Solar Companies in Virginia
Before signing a contract with a solar power company, it’s important for Virginia homeowners to do their research and find a company that best fits their needs. While many customers are likely to find a good fit in this list of the best solar companies in Virginia, others may need to look outside this list to find the best fit for them.
Regardless of whether a homeowner goes with a company in this roundup or a different company, it’s important to make sure they fully understand the contract they are signing. They’ll want to review the contract to make sure the layout and number of panels will provide the power they need, the price fits within their budget, and the installation time works with their schedule. It’s also a good idea for a homeowner to ask questions about how the solar panels work, what happens if the system overproduces, and the best options for financing the system. The best solar companies will be more than willing to answer any questions a customer may have to the best of their ability.
Cost of Working With One of the Best Solar Companies in Virginia
While the exact cost of solar panels for homes will vary from customer to customer, Virginia homeowners can expect to pay an average of $3.03 per watt of power. This means a homeowner will pay around $15,150 to install a 5-kilowatt solar system on their home. That cost can rise to an average of $30,300 for a larger 10-kilowatt system. However, some of these costs can be offset by taking advantage of available tax credits and rebates. Customers can also look into the best solar panel loans if they need financing options beyond what their chosen company offers.
The federal government offers a residential clean-energy credit for homeowners who install solar panels. This can decrease the total cost of the system by up to 30 percent. With the full tax credit applied, this can decrease the cost of a 5-kilowatt system to $11,211 and the cost of a 10-kilowatt system to $22,422. Virginia residents can also take advantage of the Virginia Clean Economy Act (VCEA) program, which will earn them solar renewable energy certificates (SRECs) for each megawatt-hour of energy produced by their solar panels. Homeowners can sell their SRECs to utility companies, resulting in extra income simply for producing solar energy.
The Advantages of Working With One of the Best Solar Companies in Virginia
The best solar companies in Virginia offer many benefits to customers who choose to work with them.

Q. Does Virginia offer a tax credit for solar panels?
Yes; in addition to the federal residential clean-energy credit that can save homeowners up to 30 percent on solar panel installation costs, Virginia has a program through the Virginia Clean Economy Act (VCEA) that helps homeowners get reimbursed for energy production. For each megawatt-hour of solar energy produced, a homeowner will receive a solar renewable energy certificate (SREC), which they can sell to utility companies.
Q. Which solar power company is the most reputable?
There are many reputable solar power companies in the market today, including those mentioned in this roundup. Reputable companies typically install the best solar panels for their customers and offer lengthy warranties for equipment and installation.
Q. Is installing solar panels worth it in Virginia?
For many Virginia homeowners, installing solar panels is worth the cost. Solar panels can help decrease a homeowner’s reliance on fossil fuels, which can be a benefit in the eyes of many. To determine whether installing solar panels is worth it, Virginia residents will want to consider their home’s energy usage and the amount of sun exposure their roof gets; if they have high usage and a roof that sits in full sun most of the day, solar panels are likely a worthwhile investment. However, homeowners will want to keep in mind that, since energy prices are relatively low in Virginia, it can take a homeowner around 13 years to recoup their investment, which is slightly above the national average payback period of 12 years.
Q. How many solar companies are in VA?
There are currently more than 70 solar companies operating in the commonwealth of Virginia.
Q. How much does it cost to install solar panels in Virginia?
The average cost for residential or commercial solar panel installation in Virginia is $3.03 per watt of power. A 3-kilowatt system will cost around $9,090 to install, although tax rebates and incentives can decrease that cost to $6,727. On the high end, Virginia residents can expect to pay an average of $30,300 for a 10-kilowatt solar system, or $22,422 with the full federal tax credit amount applied.
Q. Can I install my own solar panels in Virginia?
While technically allowed, it’s generally not recommended for homeowners in Virginia to install their own solar panels. An improperly installed system can lead to major roof damage, which can add significant cost to the overall project. In addition, homeowners attempting to install solar panels themselves are at risk of injury from falling or electrocution, and they may find that their system underproduces energy. Finally, professional solar installers can ensure that the system will qualify for any available tax incentives, which will save the homeowner money on the overall project costs. Homeowners can search for professionals in their area with an online search such as “solar installers Northern Virginia.”
