Factors that Affect Solar Panel Costs in Annandale
The cost of installing a solar system in Annandale can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The biggest one is your system size, and other factors include the equipment you choose, financing options and the solar installer you choose.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. That’s why it’s a priority to accurately gauge the size of the solar energy system needed for your home by figuring out your typical energy use.Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Annandale, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
For some homeowners, paying for solar out of pocket can be a challenge. Solar loans are offered by most installers in Annandale, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more affordable.However, the interest on solar loans also adds to your all-in costs, so it’s important to take that into consideration as well. You can always bring down the total you pay in interest and sometimes even your APR by putting more money down.
Solar Panel Installation Company
Finally, the company you opt for to install your solar system can impact the cost. Annandale’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or additional services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you select the right company for you, here are some tips to keep in mind:
- Warranty: A high-quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
- Reputation: Your solar installer should have a sound reputation as a company and have proven expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from previous customers.
- Contract: Review the contract terms thoroughly to make sure you understand how much it will cost, project timeline incentives and warranties.
- Installation Process: When going solar, it’s essential to maintain an open line of communication with your solar panel installer. See to it that you understand how the installation process will go and the project timeline.

EcoWatch's Annandale, VA Solar Cost FAQs
How much does it cost to install solar panels in Annandale?
This is a hard question to answer exactly, because the cost depends on a few different factors. Generally speaking, it costs about $17,950 for a 5-kW system and $35,900 for a 10-kW system after the ITC is applied. It will cost more if you want extra solar equipment or more efficient panels, or if you have above-average energy needs. On the flip side, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.
What other factors should I consider apart from cost when buying solar panels?
Cost is without a doubt one of the most important things to keep in mind when buying solar panels, but other important factors include efficiency, durability, and quality.
Is making the switch to solar worth it?
Solar panels can be a good investment for most homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your power bills are already pretty low, solar panels might not be for you.
How long do solar panels last in Annandale?
Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is their energy production will have decreased significantly after that point. You can choose to replace them after having them for that long or you can continue to use them at a lower efficiency.
