In Massachusetts, the cost of a solar power system can vary depending on several factors, such as the size of the system, its components, and the configuration. The typical 5-kilowatt system costs around $15,000 to $25,000 before federal and state tax credits and rebates.
A typical residential solar system’s break-even period is around six to nine years.
Solar panels for sale in Massachusetts
Solar panels in Massachusetts are reliable and cost-efficient energy generators for your home, business, RV or a boat. They work as long as there is daylight, aren’t afraid of winds, hail, snow or rain, and last for over 25 years.
The average size of a home PV installation in the US is 5-6 kW. A system of this capacity covers 80-100% energy needs of a medium house. Its cost may vary from $5,000 to $10,000, depending on the panels’ brand and incentives available. Since a solar system powers your appliances during the day, your energy bills reduce greatly. Overall, a PV installation brings in around $100 each month on average and thus pays for itself in 6-7 years.
Solar energy is a great solution for boondockers and sailors as well. Since panels work everywhere, don’t need fuel, don’t smell and are silent, they start to replace gas generators, which traditionally were used to charge house batteries. Sometimes even one panel is enough for everything you have on your boat or RV. Generally, panels go on a trailer roof, and when it comes to marine installation, modules are fixed on a stern rail, deck or canvas.

Solar inverters for sale in Massachusetts
Inverter is another necessary component of a solar panel system. The panels by nature produce direct current which can’t be used by most house appliances. That’s why an inverter converts DC to AC and sends it either into the grid or to your appliances.
Another functions that inverter perform include:
- Interaction with the grid;
- Arc fault prevention and protection;
- Optimization of the solar array production;
- System monitoring.
Inverters can be grid-tied, off-grid or hybrid. While the names of the first two are self-explanatory, a hybrid inverter can be used both as a grid-tie or an off-grid one. In other words, you can pair it with a battery, and if a blackout happens, the inverter switches your house to battery support instead of shutting down.
Inverter is the most complicated part of a solar installation and it requires proper maintenance. For Massachusetts residents, it is recommended to put an inverter in a cold dry place out of direct sunlight — the garage is the best option. To prolong its lifespan, wipe the dust off of it, clean air intake filters and check the screen for errors.

What solar panels should I install in Massachusetts?
With the ability to customize your solar panels and systems, property owners can now make their own decisions regarding the aesthetic and performance of their system. However, this customization can also make it important for consumers to understand the various factors that go into making a decision.
Depending on the size of the project, you might also need to consider the efficiency of the solar panels that will be installed on your property. Also, the type of warranty that will be offered will be important to determine if it’s right for your needs.
The history of solar power in Massachusetts
During the 1970s and 1980s, Massachusetts started exploring various green energy options. The state enacted various tax credits and incentives to encourage the use of renewable energy. Some of the bills that the state has passed over the years are the Electricity Restructuring Act and the Self-Generation Act.
In 2021, Massachusetts is regarded as one of the most prominent states in the country for solar energy generation. It has the highest concentration of solar energy in the nation and is responsible for over 18% of the state’s electricity. The industry has created over 10,000 jobs and is expected to generate over $10 billion in annual investment.
