Boston solar system installation costs


There are things to consider when it comes to planning and finally purchasing solar panels in Boston. You have to look at many points, including price, budget, capacity, environment, etcetera. It can be quite a process and sometimes a hassle, but a good purchase starts with an assessment.

Installation of Solar panels can range from $9,225 up to $28,000 depending on the panel’s capacity and quality. Specifically, your costs can be divided and categorized into three significant aspects for better breakdown and understanding in Boston. The breakdown can be divided into the following.

  1. System size
  2. System cost
  3. System cost after ITC.

In this case, the solar panel installation cost is calculated by system size. The average price of a solar panel in Boston is about $2.86 to $3.10/W. Given this rate, purchasing a solar panel system with a capacity of 5 kW can cost you about $15,198.


As the system size increases, the system cost also increases. This means installing a solar panel with a system size of 6kW will cost twice the price of a panel with a system size of 3kW.


After the system cost, the next thing to think about is the installation cost. In installing a solar panel, the price can vary from state to state and area to area. Price can start from $0.59 per Watt, at most 10% of the total system cost. The total of your expense is inclusive of the labor costs for an electrician and non-electrician aspects.

Installation, aesthetics, and positioning can be customizable. This is to further cater to the customer’s wants and needs considering all the other factors presented to them.

Nevertheless, the installation cost can vary from area to area and the amount of kW you want for your home or establishment. Therefore, if you install a solar energy system of 1 kW to 10 kW, you can expect the installation cost to start from $3,000 to $30,000.

What to Look for When Installing Solar Panels in Boston


Before installing your solar panels, aside from knowing where your money should go, you should also consider checking some other things like the climate, peak hours, angles and directions and etcetera.

As for Boston, the climate can be colder than expected. It could be getting colder, especially as winter is approaching. This could lead to the thought that installing a solar energy system would be pretty useless.

However, to debunk that thought, it’s good to remember that it isn’t exactly the heat that makes the panels work. The process occurs when sunlight hits the reactive solar cells.

In short, even when you don’t feel the heat, as long as sunlight is present, the panels are still doing their work. Despite the cold air and the winter times approaching, as long as there is sunlight, your panels will work just as fine.

This does not mean the temperature does not have an effect, though. The temperature can still have an impact on the panels. Note that it can only affect efficiency and not destroy the whole process at all. Both overly hot and overly cold temperatures can affect the panels.

A temperature exceeding 77°F will cause the panel efficiency to decline. This information can prove that colder temperatures are better for solar panels. A good quality panel is at 25% and more efficient.

The angle and direction of the panels also matter upon installment and in the planning process. In the northeast, the best angle for your solar energy system is facing south. This does not mean that panels facing north are useless. It’s just that panels facing south have an advantage in terms of maximizing their energy production for the whole day.

If you chose a fixed tilt for your panel, the best angle is 35.3°. However, when you choose to have the option of tilting two or four times a year, here are the recommended angles for the following:

For two-season tilt

  • Summer – 18.4°
  • Winter – 56.2°

For four-season tilt

  • Summer – 14.6°
  • Winter – 61.7°
  • Autumn & Spring – 39.2°

As you plan for installment and purchase, it’s good to consider these things to know how to address minor and significant obstructions and barriers.


Now, with ample knowledge through research, you will be able to choose the best choice for your solar project. This article has provided basic information and perhaps, an introduction to the whole solar energy system installation process.
