Factors that Affect Solar Panel Costs in Derry
For many Derry homeowners, the decision to adopt solar energy depends on cost. However, the range of solar installation costs can be quite wide in Derry, with typical prices between $20,000 to $40,000. There are various factors that considerably influence the price you’ll pay, which we'll go over below.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. Because of that, it’s crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs.Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Derry, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or limited space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
If paying for a solar system out of pocket is difficult, solar loans are an affordable option because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.When estimating your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.
Solar Panel Installation Company
Finally, the company you opt for to install your solar panel system can affect your pricing. Derry’s solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Derry have more knowledge about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.
