Factors that Affect Solar Panel Costs in National Harbor
There are a number of criteria that can influence your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.
Solar Equipment
One of the most important factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to pay about $3,540 per kilowatt in National Harbor.The brand and type of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
For some homeowners, paying for a solar system out of pocket can be financially overwhelming. Solar loans are offered by most installers in National Harbor, 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 increases your all-in costs, so it’s crucial to take that into consideration as well. You can always lower the total you pay in interest and in some cases even your APR by putting more money down.
Solar Panel Installation Company
The solar installer you go with to handle your switch to green energy can have an effect on your total costs. There are about 3 solar installation companies operating throughout National Harbor, and each can charge varying amounts for labor and equipment.Larger national companies usually have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric car charger installation, they might be cheaper overall.
