Solar and Energy Storage System Configurations: Central TX
Each of the year-one case studies described in Scenarian’s articles are built on models including a solar array, an energy consumption profile, and an energy storage model (when applicable). All models that are linked to this page will share a…
Notes on Internal Rate of Return (IRR) Calculations
Introduction A solar + energy storage system (ESS) project can be thought of as an asset which produces a cash flow each month, typically offsetting the owner’s electricity bill. In order to determine the viability of such a long-term project,…
Other Factors to Consider
There are numerous variables that determine the viability of a solar energy project. Many of these variables were baked-into the year-one case studies presented on this website. Other factors involved—such as efficiency losses and system‑upkeep costs—act on a longer timescale…
Lithium-Iron-Phosphate Batteries
An improvement on previous generations of lithium-ion batteries, lithium-iron-phosphate batteries feature a lithium-iron-phosphate (LiFePO4) cathode material. This newer electrode material is known for its structural stability and relatively low cell voltage (compared with those of conventional layered-oxide materials). The combination…
Lithium-Ion Batteries
Lithium-ion batteries have revolutionized energy storage, allowing items such as laptops, cell phones, and electric vehicles to take their present forms. Known for their high power density and energy density, traditional lithium-ion batteries have a few particular drawbacks. These include…
Solar & Energy Storage with Time of Use Energy Plans
What are Time of Use Energy Plans? Time of use (TOU) plans charge customers for their energy usage according to a price that varies throughout the day. On-peak rates usually occur in the late afternoon and early evening when people…
Solar & Energy Storage with Real Time Energy Pricing
Introduction A lot of people become interested in solar as a way to make it through grid-down situations. Let’s follow-up on our real time pricing scenario and see how solar coupled to an energy storage system (ESS) compares to a…
Real Time Energy Pricing Solar Array Optimization
Introduction This article follows-up on our net metering case study. Oftentimes, people want to know what will happen if their net metering energy policy is replaced with something else. You might even have questions about a house with solar panels…
