Factors that Affect Solar Panel Costs in Lake Grove

While the average cost of a solar system in Lake Grove is $8,033, your actual cost may be above or below the average. There are many factors that can have a sizable impact on the cost of a residential solar panel installation. Below are some of the more crucial things to consider.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. Because of that, it's important to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs. Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Lake Grove, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or limited space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Solar panels can save you money on energy bills over time, but they can also be a big investment. That's why many Lake Grove homeowners opt to finance their solar panel systems to offset upfront costs. It's a good idea to add the interest you'll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and how long it'll take to pay off the loan.

Solar Panel Installation Company

A final consideration when trying to figure out the cost of solar for your home or business in Lake Grove is the company you hire to install your solar panel system. As with choosing a company to renovate your kitchen, for example, there are plenty of solar installers that provide a range of services for different budgets. Larger national companies generally have lower costs, but some local companies compete with them by offering sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

Since the type of solar panels and the installer you choose has an impact on your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Contract: It's important to look over your solar installer's contract carefully to understand what services they will provide, what the warranty covers and what you can expect about the cost.
  • Solar Panel Brands: Each solar panel brand and kind has varying levels of quality, durability and energy efficiency. They will come at different costs as well. The company you choose has an impact on which solar panel brands you have access to.
  • Reputation: Your solar installer should have a sound reputation as a company and have demonstrated expertise in the field. Two ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from past customers.
  • Installation Process: Make sure you're aligned with the installer with regard to how the installation process will go and what you need to do before your solar panel system is installed, such as updating or replacing your electrical system or roof.

EcoWatch's Lake Grove, NY Solar Cost FAQs

What is the average cost of installing solar panels in Lake Grove?

This is a hard question to answer exactly, because the cost depends on a few different factors. Generally speaking, it costs about $14,750 for a 5-kW system and $29,500 for a 10-kW system after the ITC is applied. It will cost more if you want additional solar equipment or more efficient panels, or if you have higher-than-average energy needs. Conversely, you can spend less if you choose a smaller solar panel system or cheaper solar panels.

What other factors should I consider aside from cost when buying solar panels?

Cost is definitely one of the most important things to keep in mind when buying solar panels, but other important factors include efficiency, durability, and quality.

Does Lake Grove have a net metering program?

Most states have net metering programs of some kind. Through these, you can get paid for the extra power your system produces or or receive credits to put toward future electricity bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How long do solar panels last in Lake Grove?

Even though 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 decide to replace them once you've had them for that long or you can keep using them at a lower efficiency.
