LEADERS IN QUALITY Solar Installations
Grid-Tied is the most common way to install solar. It gives you the reliability of the grid and the financial stability of solar.
For those customers who cannot get electrical service to a property or want to be energy independent. Off-Grid systems let you take your power in your own hands.
Battery back-up systems can be paired with or without solar panels. We have a wide selection of products to choose form. These can be designed to back up anything from a single room to an entire house.
An Offline Solar system will provide decades of clean, secure energy while increasing your property's value. While some solar installers give you a system that sets you up as a landlord for 10 years, our systems are yours forever. Offline Solar, your best choice. Powered by the sun since 1982.
Brooke Hanner has been involved in the electrical industry for over 30 years, and he started his successful contracting firm in 1990 in Oceanside, California. Brooke shares his predecessor’s enthusiasm for solar living and energy independence, and five years ago he and his wife, Karen, returned to Mariposa County to begin living in the sun-powered home that Brooke designed and built with an off-grid PV system that Brooke designed and installed. “It’s a great feeling to know that we are producing our own power, that we are more energy efficient than ever,” says Karen.
One of the Hanner’s friends suggested that Brooke meet the local, solar company owner who had built her off-grid system. Consequently, several energetic and fruitful discussions ensued over at the North Fork offices of Offline Solar. As the result of those meetings, Brooke Hanner became the new owner of Offline Solar. He is continuing the company tradition of locally-owned and respected business leadership, where each grid-tie or offline project is designed to suit each customer’s unique needs. Brooke and Karen look forward to meeting old and new Offline Solar customers in our Mariposa office soon!
