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 depends on several factors. The most significant one is the size of the system your household needs, and other factors include the equipment you choose, financing options and the solar installer you choose.
Solar Equipment
When it comes to estimating the price of a solar system in Holliston, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy consumption, which you can determine by looking at past energy bills. Your overall cost can increase by about $2,940 for each additional kilowatt you need. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Holliston, where sunlight is relatively abundant, efficiency can quickly pay off. Also, 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
Many homeowners find the average cost of solar in Holliston to be too expensive, even if the investment pays off over time. Fortunately, nearly every solar company in the area provides financing options. Solar loans drastically decrease upfront costs in most cases, but they also result in higher prices over time due to interest. You'll have to consider the long-term cost of loans, 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
Finally, the company you get to install your solar system can play a part in determining the cost. Holliston's solar companies all have different labor costs and add varying upcharges to equipment. Companies that only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It's best to do some research and decide on the company that provides the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels
There are a large number of companies to choose from in Holliston, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be tough, so here are some tips to help you decide:
- Contract: Before you sign a contract with a solar company, make sure to read it through fully so you understand the terms. Also, ask questions if you're not certain about some of the terms, such as what to do if a component breaks or malfunctions and what services you can expect from them.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to get the job done well. Another way you can look into your installer's reputation is by reading reviews.
- Warranty: Warranties that provide coverage for panel repairs and maintenance over a couple decades are the best you can get in the business, and offering such a warranty is one mark of a quality company.
- Solar Panel Brands: The kind of solar panel you want to get plays a part in which installer you should go with, since different companies offer different panels.
