Factors that Affect Solar Panel Costs in Waltham
There are many factors that can determine your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power production use better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,940. The brand of solar panels and equipment you get is another factor that will significantly influence costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Moreover, solar equipment is more than just the solar panels themselves. You'll also need to make decisions 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 researching a solar system that's in your budget.
Solar Financing Terms
Solar panels can save you money on utility bills over time, but they can also be a significant investment. That's why many Waltham homeowners decide to finance their solar panel systems to make going solar more affordable. However, the interest on solar loans also increases your overall costs, so it's vital to keep that in mind as well. You can always reduce the total you pay in interest and sometimes even your APR by putting more money down.
Solar Panel Installation Company
The last key cost factor you should take into consideration is the installer you choose. Given the booming popularity of green energy solutions in Waltham, you'll have plenty of options to choose from, but each comes at varying price points for labor and equipment. Larger national companies generally have lower costs, but some local companies keep up with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
The company that does your solar system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since selecting a company can be difficult, we have some tips to help you, such as:
- Installation Process: Homeowners should make sure they know how exactly the installation process will be carried out, as well as important factors like the project completion timeline.
- Solar Panel Brands: Homeowners will have different preferences for panels based on their locations and energy needs. While there are many options for which brand of solar panel you can get, not every company will have the exact one you may want or need, so be sure to peruse their list of offerings before deciding.
- Reputation: Make sure your solar company has a good reputation by confirming it has certifications and licenses, checking its number of years in business and reading reviews by previous customers and solar experts like EcoWatch.
- Contract: Before you sign a contract with a solar installer, make sure you look it over fully so you understand the terms. Also, ask questions if you aren't sure about some of the terms, such as what the warranty covers and what services you can expect from them.

EcoWatch's Waltham, MA Solar Cost FAQs
How much does it cost to install solar panels in Waltham?
The average cost of solar panels in Waltham is about $14,700 for a 5-kW system and $29,400 for a 10-kW system before the ITC, but the actual cost will depend on certain factors such as the kind of solar panels you want, what size system you need and how much energy you use.
Should I lease or buy solar panels in Waltham?
Leasing solar panels can be an attractive choice, as it typically comes with low or $0 upfront payments. The drawback is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better option if you want to get the most savings.
Can you sell solar power back to the grid in Waltham?
The majority of states offer net metering programs of some kind. Through these, you can receive compensation for the extra power your system produces or or receive credits to put toward future energy 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 Waltham?
On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
