Factors that Affect Solar Panel Costs in South Portland
There are several criteria that can determine your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the key factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power generation require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,830. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like South Portland, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, 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 South Portland to be prohibitively expensive, even if the investment pays off over time. Fortunately, almost every solar installer in the area provides financing options. Solar loans substantially decrease upfront costs in most cases, but they also result in a higher cost over time because of interest. However, the interest on solar loans also increases your all-in costs, so it's crucial to include that in your estimate as well. You can always lower the total you pay in interest and possibly even your APR by putting more money down.
Solar Panel Installation Company
Lastly, the company you choose to install your solar panel system can impact your pricing. South Portland's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in South Portland are more knowledgeable about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels
There are a large number of companies available in South Portland, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be difficult, so here are some tips to help you decide:
- Warranty: Companies typically offer different kinds of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
- Contract: When looking over your solar company's contract, ask for clarification about any terms you're not sure of and be sure you understand what happens in scenarios such as a system part breaking or the company going out of business.
- Installation Process: Make sure you're on the same page with the company with regard to how the installation process will go and what you need to do before your solar system is installed, such as repairing your electrical system or roof.
- Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you choose.

EcoWatch's South Portland, ME Solar Cost FAQs
How much does it cost to install solar panels in South Portland?
The average cost of solar panels in South Portland is about $14,150 for a 5-kW system and $28,300 for a 10-kW system before the ITC, but the real cost will depend on things such as the kind of solar panels you want, what size system you need and how much energy you consume.
Is it better to lease or buy solar panels in South Portland?
Leasing solar panels can be an appealing choice, as it commonly 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 maximize your savings.
Does South Portland have a net metering program?
Each state has some form of net metering programs except Tennessee, South Dakota and Alabama currently. Some states allow you to sell power back to the grid, but others just give you credit toward your future utility bills.
How often do you have to replace solar panels?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
