Current Financial Incentives

Take Action!

Contact an Installer...

To spur demand for renewable energy in the state, Colorado and many of its counties have enacted a variety of incentives for residents and businesses to “go solar.” At the state and local level, you can find help through grants and rebates that can cut your initial installation costs by up to 50%.

Couple these rebates with federal incentives and you’ll find that installing solar in your home has never been more affordable.

Federal Tax Credits

Federal Tax Credits for your home system

Who is it for?

Residents in the United States

What is it about?

Under the Energy Policy Act of 2005, people who install residential solar energy systems are eligible for a federal tax credit. Taxpayers may claim a credit for 30% of expenditures for their home solar system through 2016.

Eligible expenditures include labor costs for on-site preparation, assembly and system installation, and wiring to connect the system throughout the house.

You can learn more about federal tax credits for going solar by exploring the EnergyStar website.

Business Energy Investment Tax Credit

Colorado Net Metering

For many consumers, the idea of creating enough energy to sell back to the utilities companies is a dream come true. Unfortunately, in many states, this process known as “net metering” is limited, and doesn’t provide a huge incentive for many people.

However, Colorado is rated one of the best states in the country for net metering, receiving an “A” rating from “Freeing the Grid,” a policy guide that tracks net metering legislation in the United States.

On a sunny day when you’re using little to no power in your house, you might go outside to see your electrical meter literally running backwards. This is because you’re generating more electricity than you’re using – electricity that is banked onto the grid in the form of kilowatt-hour (kWh) credits.

During periods when you pull power from the grid, that power is actually deducted from the credits you’ve accrued. This means that at the end of the month, any power you took from the grid is offset by the credits you’ve earned – lowering and sometimes even completely negating your bill for that month.

In Colorado, at the end of a 12-month period, if the energy you’ve generated exceeded your annual use, you can actually sell that energy to the utility company at a cost slightly lower than the retail value for the prior year.

Net metering does have limits – in Colorado, solar systems can only generate 120% of your annual energy needs for you to be eligible for net metering. This is to prevent consumers from installing oversized systems that take advantage of net metering policy.

What is a Renewable Energy Certificate (REC)?

Xcel Energy, one of the largest Investor-Owned Utility (IOU) companies in Colorado, offers incentives based on Renewable Energy Certificates (RECs) their customers earn by generating electricity.

A renewable energy certificate, also called renewable energy credit, is essentially a form of currency that takes into account the non-tangible aspects of renewable electricity. Based on federal and state law, a REC is composed of both the actual electricity, plus its green attributes, such as greenhouse gas emission offsets.

What does an REC tell you?

As companies seek to increase the amount of renewable energy they provide, RECs will become a hotly traded commodity in the future. While RECs might seem like a made-up and unnecessary creation, they actually provide important information about the energy you use, such as:

  • The type of renewable resource producing the energy
  • The date it was created
  • The date the generator, like a solar panel, was first set up (known as vintage)
  • The location of the generator
  • How much greenhouse gas the energy offsets

Each REC is created as the result of generating one megawatt-hour of electricity from renewable sources. These credits are growing in importance as regulations increase the amount of renewable energy utility companies must provide to customers. Essentially, utilities use RECs to prove that renewable energy sold to individuals or businesses came from a renewable source.

In Colorado, Investor-Owned Utilities like Xcel Energy must generate or purchase 10% of their electricity from renewable energy sources. This number is set to increase to 15% by 2015, and further to 30% in 2020.

In order to reach this goal, more utilities companies are looking to buy RECs from independent energy creators. For example, under the current Xcel Energy Rebate program, consumers enter into an up to 20-year contract to sell the REC’s they generate to Xcel energy, helping Xcel reach their required renewable energy goals.

In return, they are paid for the sale of the REC – earning $.11 per kWh of energy they sell to Xcel Energy.

Future Innovations in Solar Financing

In Europe, particularly Germany, massive growth in solar energy use has been linked to their policy of feed-in tariffs – a financial incentive designed to encourage the installation and use of renewable energy.

Feed-in tariff policies are somewhat similar to net metering policies, in that they allow renewable energy generators to earn money for their solar output. However, while net metering helps offset your energy bill, feed-in tariffs actually allow you to enter into contracts with utility companies who are obligated to buy all of the energy you create.

Under a feed-in tariff program, you receive a guaranteed payment from the utility for your energy production. Instead of simply offsetting your own energy use, you must sell all generated energy to the utility company. In the contract, the utility company is obligated to purchase all generated energy, while you’re obligated to sell all of the energy generated.

In Germany, feed-in tariff programs have driven the renewable energy industry toward a boom. Since introducing the program in 1991, renewable energy jumped from 5% to over 20% in 2011.

Over 63 countries, states, and provinces have created feed-in tariff programs, but the idea hasn’t caught on as strongly in North America. Some states have proposed their own programs, but many are currently stalled.

To get an idea of how much money you could earn through a feed-in tariff program, consider California, which has explored the concept. In the state’s research, the California Public Utilities Commission estimated starting prices for energy at $89.23 per megawatt hour.

As more states look toward new ways of generating interest in solar energy, feed-in tariff programs will continue to be considered. Most recently, in 2011, Colorado representatives introduced bills that would prompt the study of a feed-in tariff program in the state. Unfortunately, these bills did not pass, currently stalling the effort in the state.
