Solar power in Denver, Colorado

As a resident of Denver you are probably buying your power from Xcel Energy.

Excel Energy offers 1 for 1 net metering as a key incentive to support its customers to install solar power on their homes.

What this means is that in periods (usually during the middle of the day) when your solar system is producing more power than your home is using, you are credited for the excess solar energy you feed back into the grid at the full retail rate of power.

Because solar systems generate most power during the middle of the day, and most households use most of their power in the evening, net metering is a key reason why installing solar panels on your home in Denver can have a short payback period and offer excellent long term returns.

Why net metering in Denver is better than in some other places?

If in any given month your solar system exports to the Excel grid more electricity than what your home drew from the grid Excel will pay you for this excess.

The excess is valued at the retail per kWh rate. You can elect to be paid out this value in cash or roll the value forward for use as a credit against possible future electricity bills. In many other jurisdictions you are not paid cash for your excess export if it is above your usage from the grid or are paid out at a lower avoided cost rate for solar export. 

Are there also upfront incentives to install solar panels on my home in Denver?


Xcel Energy also offer a REC (Renewable Energy Credit) program however, unless your system is over 25kW the credit is only $5 per MW of solar energy. Even a 10kW solar system, which is larger than the typical sized resdential solar system installed on a home in Denver, only makes about $60 a year from REC's, but hey it's better than nothing.

The major up front incentive to help you cover the cost of installing solar panels on your home is the 30% solar tax credit. Whilst we refer to this as an upfront tax credit you do not receive the cash benefit of this until you do your taxes for the year in which you install the solar system. This means receipt of the tax credit can be up to 18 months after you install your system depending on when you install it and when you do your taxes for that year. Claiming the full value of the 30% tax credit requires you to have a tax liability against which this credit can be claimed.

Even if you are not convinced about solar we recommend that at the very least you use the solar panel calculator for Denver to find out:
