Factors that Affect Solar Panel Costs in Westminster
The cost of installing a solar system in Westminster can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The most significant one is your system size, and other factors include equipment choices, financing options and the solar installer you choose.
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 around $3,470. Some solar brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like Westminster, where sunlight is 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
For some homeowners, paying for a solar system out of pocket can be a challenge. Solar loans are available from most installers in Westminster, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more accessible.It’s wise to add the interest you’ll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and the amount of time it’ll take to pay back the loan.
Solar Panel Installation Company
The solar installer you choose will affect your total cost to go solar. Different companies will charge different amounts for the equipment and labor.The size of the company can sometimes play the most considerable role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower pricing because of more resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger names.

Can you get solar panels for free in Westminster?
You can’t get solar panels for free in Westminster. However, you may still be able to install them on a lower budget. You can lease solar panels for a low upfront cost or, if you’d rather own your solar panels, you can finance them with a solar loan.
Is making the switch to solar worth it?
Solar panels can be a good investment for a majority of homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your energy bills are already reasonably low, solar panels might not be for you.
How long do solar panels last in Westminster?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is how much energy they produce will have decreased significantly after that point. You can choose to replace them after having them for that long or you can keep using them at a lower efficiency.
