GREEN INNOVATIONS FOR CLEAN ENERGY
SmartFlow – Intelligent Energy Management
By combining solar, storage, and grid intelligence along with extracting multiple value streams, SkyElectric’s Smart Energy System can provide you with 10-30% more annual savings than a conventional solar energy system that lacks sophisticated energy management intelligence.
Our patented intelligent energy management software, SmartFlow, continuously receives solar, grid and load predictions from the SkyElectric cloud. It therefore has up-to-date knowledge of predicted solar irradiance levels, grid tariffs and outage schedules, and cloud machine learning based prediction of local load levels. Utilizing this cloud delivered knowledge, SmartFlow computes and updates optimal Power Management Plans. SmartFlow is integrated into your system to autonomously control when your battery charges, discharges or remains idle, when your loads are powered by solar or the grid, and when your system net-meters to the grid. SmartFlow always chooses your cheapest energy resource, giving you maximum savings possible from a solar and energy storage system. Moreover, your Smart Energy System provides you visibility into SmartFlow energy intelligence through your Console and SkyElectric mobile app.
SmartFlow Value Streams
Solar Production and Load Consumption
Here is an overlapping solar production and load consumption graph showing the typical household load patterns throughout the day as well as solar energy production in the daytime. There is little overlap between peak load consumption and peak solar energy production, which means the majority of solar energy, shaded yellow, will be wasted if it is not intelligently managed. SmartFlow extracts multiple value streams to more fully utilize all the available solar energy as well as reduce overall grid electricity usage.
Basic Solar Exporting
If net-metering is enabled at your home or business, SkyElectric systems have the ability to export excess solar energy back to the main grid. When the solar production peaks during the day, there is typically excess solar energy available which, if not sold back to the grid, will be wasted. In these situations, SmartFlow enables the Smart Energy System to export the excess solar energy back to the main grid. The system keeps tracks of all energy units sold as well as consumed from the main grid so you always have an accurate and up to date account of how your solar energy is being used and your net energy bill.
Intelligent Exporting During Aggressive
Even if net-metering is available at your home or business, there is no ability to export energy to the grid when the grid is turned off. Using knowledge of the grid outage schedule, SmartFlow intelligently exports the battery packs to the main grid prior to an outage, in order to ensure there is sufficient energy storage space available for the excess solar energy. SmartFlow then charges the battery pack using excess solar energy during the grid outage period, thereby ensuring all available solar energy is captured. Then after the outage and before the next outage, SmartFlow again exports the battery packs to the main grid to ensure there is sufficient energy storage space before the next outage. This process repeats for each outage period, and this approach ensures that minimal to no solar energy is wasted even though the local loads are low and there is no direct ability to export to the main grid during an outage period.
Increase In Solar Energy Self-Consumption
Maximum solar energy production occurs during the day when home load requirements are typically low. If there is no battery storage, then a lot of useful solar energy is wasted. In the evenings when load requirements increase, you will have to rely on the high tariff grid for electricity. By intelligently storing the solar energy into your battery during the day, and releasing this solar charged battery energy in the early to late evening time frame, you are able to consume the locally produced solar energy even when the sun is not shining. This translates into a direct economic benefit, even if local utility policies support net metering, as the rate paid by the utility to purchase excess solar energy via net metering is typically lower than the rate to purchase the grid electricity in the evening, due to high peak time-of-use tariff structures.
Time of Use (TOU) Energy Arbitrage
In simple terms TOU energy arbitrage means to fill up the battery with cheaper energy from the low tariff grid and use the battery to power home loads when the grid is on and the tariff rate goes up. This ‘energy arbitrage’ helps you to save money by reducing your electricity bill. For example, if the local utility provides TOU pricing models, then it is advantageous to consume power when the rate is low, and lower the power consumption when the rate is high. Since most residential consumption occurs during peak rate periods, over time the savings of such an economic value stream can be substantial. This allows SmartFlow to provide an economic value stream even in completely cloudy days where there is little to no solar irradiance, as grid TOU energy arbitrage can always be performed as long as there is a TOU tariff structure in effect for your premises.
