Many markets require the deployment of small-profile, low-power-producing solar systems. Solar systems are usually deployed to power equipment such as sensors, telemetry radios, data loggers, process control equipment, video cameras, and so on. The high cost of delivering typical 110vac house power to a remote site is cost prohibitive.
The challenge is to provide uninterrupted power to remote critical sites, and balance the sizing of solar panels and the number of batteries to maintain power through various conditions. These conditions might include bad weather, sustained low-to-no sunlight,, and the changing dynamics of the user adding equipment over time.
Today, the practice of calculating or determining the size of a solar panel and the number of battery amp hours is a “paper exercise”, where a user determines the estimated power load on the system, geographical locations to determine weather patterns and solar exposure, and the desired and required days of autonomy. This process is static, is an estimate, and does not allow for dynamic changes such as aging solar panels, aging batteries, the adding of equipment over time, and the natural process of charging and discharging cycles.
The need is to overcome:
✓ UNPREDICTABLE UPTIME
✓ LACK OF SYSTEM PREFORMANCE AND VISIBILITY
✓ UNKNOWN POWER DISRUPTIONS
✓ UNKNOWN STATE OF CHARGE
✓ UNKNOWN HOURS OF AUTONOMY
✓ PREMATURE BATTERY FAILURE
✓ DAMAGING DEEP DISCHARGING OF BATTERIES
✓ STATIC SYSTEM DESIGNS FALURES BY DYNAMIC SYSTEM ATTRIBUTES
✓ TECHNICAL ROLLOUTS
