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:
Installing solar panels can lower your electricity costs and help the environment by reducing your carbon footprint. When determining whether a solar provider is the best option for you, consider these key factors.
It's imperative that your solar installer has the proper licensing. This helps ensure that the work is done correctly using the most up-to-date installation methods. While electricians and plumbers in Colorado have state-issued licenses from the Colorado Electrical Board or Colorado State Plumbing Board, the state's unique home-rule structure means counties and cities can issue solar contracting licenses if they choose.
Check review sites like Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to see feedback from past customers about local solar companies. Detailed reviews can help you evaluate a company's dependability and level of service. Use caution with companies that have no reviews or mostly negative ones.
Call 3–5 solar companies for free, itemized quotes. The quotes should outline all costs and list the solar equipment included. Reviewing multiple quotes helps identify the best option that fits your budget.
Quality solar installations should have comprehensive workmanship and performance guarantees. The workmanship warranty covers any installation issues such as poor wiring, poor alignment, or cracks in the panels. The performance guarantee promises a specific energy output level. Strong guarantees indicate that a solar installer trusts its installations.
Going solar can help lower your electric bills over time. When evaluating the total price and value of solar panels, be sure to consider these factors.
The cost of home solar panels in Frederick depends on several factors, including the size of the system and the type of panels you'll use.

2015 Large RFP Program: Incentive Amount: Refrigerators/Freezers: $30 A solar photovoltaic (PV) system can generate power to run any electric appliance or system in your home. More specifically, you can install a solar heating system for your water. With home solar panels, you can save money on your energy bill, lower your home's carbon footprint, and be better prepared if there's an outage to the local grid. Yes, you can use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, meaning that you can reap the environmental benefits and savings that come from using solar energy without having to completely switch over. 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 Frederick amount to $1,078. Your payback period is the time to achieve an ROI on your solar panels. It will vary based on the average sunlight in your area, their rated capacity, and the rate your utility charges per kilowatt of power. Frederick has extremely high daily sunlight levels, so you could recoup your investment in as little as 13.5 years per 5 kW of rated capacity. Regarding taxes, the federal government offers a tax credit of up to 30% of the panels' cost. Depending on where you live, you could also claim or apply for state or property tax incentives. Regarding insurance, your monthly premium may be slightly higher because solar panels increase your property's value. You should talk with your accountant or insurance agent for information specific to your case. Solar energy is on par with other forms of renewable energy. They have low maintenance costs and today's systems can work in a variety of conditions.
