Factors that Affect Solar Panel Costs in Holliston
The cost of installing a solar system in Holliston can vary by more than $10,000 from home to home. Your actual cost is determined by 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
One of the most significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household uses, the larger your system will likely need to be. You can expect to pay about $4,060 per kilowatt in Holliston.The type of solar panels and equipment you get is another factor that will significantly influence costs. Solar panels that are more efficient, like monocrystalline panels, tend to be more pricey. Furthermore, solar equipment goes beyond just the solar panels themselves. You’ll also need to think about 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 into a solar system that’s in your budget.
Solar Financing Terms
Solar panels can save you money on energy bills over many years, but they can also be a big investment. That’s why many Holliston homeowners opt to finance their solar panel systems to make paying for solar more affordable.It’s a good idea to factor the interest you’ll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and the amount of time it’ll take to pay back the loan.
Solar Panel Installation Company
The solar installer you hire to handle your switch to clean energy can play a part in your total costs. There are about 3 solar panel companies operating throughout Holliston, and each can charge different amounts for labor and equipment.Larger national companies usually have lower costs, but some local companies undercut them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or extra services like electric car charger installation, they might be cheaper overall.

The solar panel company you opt for will be a major factor in determining not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should keep in mind, such as:
- Installation Process: Make sure you’re on the same page with the installer in regard to how the installation process will go and what you need to do before your solar panels are installed, such as repairing your electrical system or roof.
- Reputation: Companies that have been operating for many years likely have a good reputation. This is important because it ensures that it will not only see your solar project through, but will also provide adequate aftercare and customer service, such as part repairs and replacements.
- Contract: When reading over your solar installer’s contract, ask questions about any terms you’re not sure of and be sure you understand what happens in scenarios like a system component breaking or if the company goes out of business.
- Solar Panel Brands: Each solar panel brand and type offers varying levels of quality, longevity and efficiency. They will come at different price points as well. The company you choose plays a role in which solar panel brands you have access to.
