Yes, a properly designed off grid system in a properly sited area can be very reliable and cost effective.
The PV array includes the solar modules, racking, grounding equipment, wiring, combiner box and whatever is needed to assemble and operate the PV modules.
SUNFIND inverter systems include charge regulators, inverters, load centres and the "tid bits" to make it an operable system.
There are inverter / inverter systems that are suitable for seasonal / light duty application and inverter systems suitable for full time / heavy duty operation. It is important the appropriate equipment is used for the appropriate application.
The battery bank is what allows energy to be stored for when production from the solar array does not meet the consumption. There are two type of technologies most used in the industry:
What is the best battery options? Here is a very quick and basic guide:
LOWEST UPFRONT COST
Wet lead acid batteries will offer the lowest upfront cost, but have a high life cycle cost. Plus, these batteries require venting and maintenance, such as equalization and watering.
LOWEST UPFRONT COST, MAINTENANCE FREE
AGM Technology offers the lowest upfront cost in a maintenance free format, but have a high life cycle cost.
HIGHEST UPFRONT COST, LOWEST LIFE CYCLE COST
Lithium Ion will have the highest upfront cost, but offer the lowest life cycle. A typical Lithium Ion battery bank will have 5,000-7000 cycle life, at a 100% discharge. By comparison, a lead acid battery will have a 400-1,500 cycle life at 100% discharge.
Full time solar systems are in Canada are equipped with fueled generators. Sunfind Solar Products recommends and only sells diesel generators. Our line of generators from Kubota offer excellent reliability and fuel economy when compared to propane, natural gas or gasoline options.
Since 2005, Sunfind Solar Products has been providing solar PV solutions across Canada and beyond. We are proud to say we hold the distinction of supplying our PV systems to every single province and territory in our great nation, giving us the unique experience that comes with operating systems in such a wide variety of climate conditions. Below is a brief overview of some of the systems we've provided.
Sunfind Solar Products designed, supplied and installed this system in Africa. The system powers entire village, bringing sustainability and economic development to the people.
