Factors that Affect Solar Panel Costs in Merrimack
While the average cost of a solar system in Merrimack is $14,627, your final cost may be higher or lower than that. There are quite a few factors that can have a sizable impact on the cost of a solar panel installation. Below are some of the more important things to take into consideration.
Solar Equipment
The size of the solar panel system you need for your household, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by about $4,220. The brand and type of equipment you choose for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Also, if you want extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
For some homeowners, paying for solar out of pocket can be a challenge. Solar loans are offered by most installers in Merrimack, which can reduce, or in some cases totally eliminate, your upfront costs to make solar more accessible.When estimating your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying more on your down payment can lower the total interest paid over time.
Solar Panel Installation Company
Lastly, the company you get to install your solar panel system can play a role in determining how much you pay. Merrimack’s solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Merrimack have more knowledge about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.
