Whether residential or commercial, grid-tie or off-grid we have a green solution for you.
There are a variety of reasons that people choose to live off-grid, for some it make sense economically, others like the independence it provides, others prefer it for the reduced environmental impact. Whatever your reasons Dandelion Renewables can design and install a off-grid solar system to suit your needs in Alberta, Saskatchewan, British Columbia.
An off-grid solar system is a solar system that is not connected to the electric grid, these solar systems are most commonly used in remote locations but works well anywhere. Off-grid solar systems have a few more components than grid-tie solar systems, such as a charge controller or solar inverter, a battery bank, battery-based inverter, as well as optional monitoring and automation equipment.
As there is only as much power available as what has been generated by the off-grid solar system, once the battery bank has been depleted, if there is no back-up power source then there will be no power.
An off-grid solar PV systems design differs substantially from the design of a grid-tie solar system. Each project has to be carefully planned around the home’s daily and seasonal electrical usage, as well as daily and seasonal availability of the sun. The off-grid solar PV system must be able to keep the battery bank charged, we also frequently recommend having a back-up generator.
Dandelion Renewables always takes time to plan and design an off-grid solar system prior to construction. We have seen and fixed too many off-grid solar systems that poorly performed over the years due to design flaws. Our design includes decomposition of AC and DC power loads, balancing solar PV system and the battery bank capacity to a given days of autonomy, sizing battery-based and generator. In the end of this design process, we issue a 15-page report summarizing all projected loads, electrical design of the recommended system as well as options to consider.
Since 2012 our company has designed and installed many off-grid systems, using different components and new concepts, including installing li-ion battery banks, designing and building AC-Coupled systems and trackers.
Living with an off-grid solar system will likely impact how and when you use electricity and will perhaps help your life-style to become more sustainable. Our recommended operations and maintenance services for off-grid projects will provide on going support and piece of mind. Going off grid is a long-term investment and we are here on the journey with you.
