Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Putting solar panels on your roof could lower your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.
It's imperative that your solar installer has the proper licensing. This ensures that the work is done properly using current best installation practices. While electricians and plumbers in Colorado have state-issued licenses from the Colorado Electrical Board or Colorado State Plumbing Board, it's up to counties and cities to issue solar contracting licenses if they choose.
Check the Better Business Bureau (BBB), Google Reviews, TrustPilot, and other review sites to see what past customers are saying about local solar companies. Detailed reviews on these platforms can help you evaluate a provider's integrity and customer service. Be wary of companies with few or mainly poor reviews.
To find a solar installer that fits your budget, get free, detailed quotes from at least three providers. The quotes should outline all costs and list the solar equipment included. Comparing several quotes helps you identify the option that best fits your budget.
Top-notch solar installations should have strong workmanship and performance warranties. A workmanship warranty covers installation issues, such as cracks in the panels, poor wiring, or poor alignment. A performance warranty guarantees a minimum energy output. Comprehensive guarantees indicate that a solar company believes in its work.
Solar is great for helping you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.
The average Castle Rock homeowner will spend around $14,333 on a home solar system after federal tax refunds. Solar arrays in Castle Rock cost approximately $3,980 per kilowatt, with the average residential solar system being 5.1 kilowatts. A personalized estimate from a local solar provider will include costs for preliminary work, permit fees, and labor, and will account for your system's size, panel type, and capacity. Some homeowners prefer to lease solar panels in order to reduce upfront costs.

2015 Large RFP Program: Incentive Amount: Air Sealing: $300-$500 Incentive Type: Property Tax Incentive Incentive Amount: Varies (local option) Generally speaking, a solar photovoltaic (PV) system can be used to power any household system or appliance that uses electricity. In the simplest case, you can use a solar water heating system. With home solar PV, you can recoup the cost of the system over time, lower your property's emissions, and gain additional energy independence. It depends on where you live and what type of panels you're installing. Castle Rock can experience long, hard winters, so we recommend installing your system in the springtime to maximize your generation for the year. Your installer can give you an estimate of what your energy bills will look like after you install solar panels. Generally, your energy bills will decrease significantly because you'll be using energy from the sun for free, instead of buying energy from the utility company. The average annual savings in Castle Rock amount to $1,147. The specific types of maintenance you need will depend on the type of panels you're using. Regardless of type, you should clean your panels regularly and inspect them for damage. Many solar contractors in the Castle Rock area offer comprehensive maintenance plans to help you make the most of your panels and keep them healthy for as long as possible. Net metering is a type of "power purchase agreement." If your state or utility offers net metering, you can send the solar energy you don't use to the grid. In return, they'll give you a credit on your power bill. Loading map...
