Factors that Affect Solar Panel Costs in Rockville

The cost of installing a solar system in Rockville can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The largest one is your system size, and other factors include equipment choices, financing options and the solar company you choose.

Solar Equipment

System size is one of the largest factors that affects the overall cost of going solar. Because of that, it's crucial to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use. The brand of solar panels and equipment you want is another factor that will largely impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more expensive. Plus, solar equipment consists of more than just the solar panels themselves. You'll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking for a solar system that's in your budget.

Solar Financing Terms

Many homeowners find the average cost of solar in Rockville to be prohibitively expensive, even if the investment pays off over time. Fortunately, almost every solar company in the area provides financing options. Solar loans drastically decrease upfront costs for most homeowners, but they also lead to paying more over time because of interest. You'll have to consider the long-term cost of financing options, including the amount of interest you'll pay over the length of the loan. If you're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low APR could reduce your costs considerably.

Solar Panel Installation Company

The solar panel installer you select will influence your total cost to go solar. Different companies will bill different amounts for the equipment and labor. The company's size can sometimes play the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of more resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger companies.

How to Save on Solar Panels

There are a lot of companies available in Rockville, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be tough, so here are some tips to help you decide:

  • Contract: When reading through your solar company's contract, ask questions about any terms you're not sure of and be sure you understand what happens in scenarios such as a system component breaking or if the company goes out of business.
  • Reputation: Solar companies that have great reviews from their customers and that have been in business for many years likely offer high-quality solar panel installation and expertise.
  • Installation Process: One of the most important things to understand when going solar is the installation process itself. Be sure to clarify any details you need to know with your solar installer, such as what permits you should acquire and how long the project will take.
  • Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you opt for.

EcoWatch's Rockville, CT Solar Cost FAQs

What is the average cost of installing solar panels in Rockville?

This is a hard question to answer exactly, because the cost depends on many factors. Broadly speaking, it costs about $14,000 for a 5-kW system and $28,000 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 higher-than-average energy consumption. Conversely, you can spend less if you want a smaller solar panel system or less expensive solar panels.

Is cost the most important consideration 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.

How much can I save on electricity bills after installing solar panels?

It is possible to eliminate your electricity bills with solar panels, but for most homeowners in Rockville, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you'll want to check with a local solar installer to see how many panels can fit on your roof.

What solar power system size is right for my home?

To figure out how many solar panels you need, you need to know how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
