Off Grid Solar Power System for Crested Butte Cabin

Our solar power project for the week features Mitchell from Crested Butte, Colorado. Crested Butte, a former coal mining town has been referenced as being "the last great Colorado ski town". It’s known as a destination for skiing, mountain biking and other outdoor activities. Mitchell served this area by being a paramedic, firefighter and part of the ski patrol. He also is a real estate entrepreneur and has been restoring historic buildings in Crested Butte for the last 40 years. His love for the outdoors kept him in the area and prompted him to purchase his own remote property.

Mitchell’s getaway is a cabin built in 1980 located on a remote 40 acres. His property is not near power or utilities, so it is considered “off-grid”. The cabin’s only light source is powered by propane, not electricity. Mitchell drilled a water well on the property that needed power to pump water to the cabin. He also needed electricity to use his satellite Internet connection in order to manage his business remotely. Since his property is considered remote, solar electricity was the obvious choice.

Our team member, Luis consulted with Mitchell about his power requirements. Luis designed a tailored solar system for Mitchell that included an inverter, a charge controller, solar panels and lithium batteries. The solar system was perfect for his power needs and he was able to install the system itself.

Actual specifications of Mitchell’s system are mentioned further down the page.

Competitive pricing!

Do you think the free consultation provided value to you?

It made the difference.

How are our customized solar systems more beneficial than out of the box solutions?

I was able to adapt the system to the cabins orientation and preexisting propane set up.

My expectations were exceeded!

Our Take

Mitchell was looking for an easy plug and play system and long lasting batteries. For the solar panel array, he wanted to start with approximately 2500 watts of solar with the ability to expand in the near future. I suggested to him the Outback FlexPower Radian (FPR-4048-300VDC). This prewired power panel comes with a very efficient 100A, 300VDC charge controller that allows you to connect panels in a higher voltage configuration which makes the installation easier. It also comes with a split phase 120/240VAC inverter/charger with an output power rating of 4000 watts that supplies enough power to run basic household appliances. Lithium batteries were also part of the design. Mitchell wanted a very efficient, reliable battery bank that can handle deeper discharges. His battery bank consisted of two Lithium Iron Phosphate Batteries with a total of 7.6kWhrs of storage capacity at 48VDC.
