! SAMA (Solar Alone Multi-objective Advisor)''' is an '''open-source (GNU GPL v3) energy system optimizer and analyzer mainly concentrated on stand-alone off-grid solar photovoltaic (PV)-based renewable energy systems (RES). SAMA allows for hybrid systems in locations that need a form of non-battery backup generation. Using SAMA, users can find the optimum size of a hybrid energy system for their property based on the electric load profile and meteorological data (irradiation, temperature and wind speed). Users are able to access economic data for their optimum energy system as the results of SAMA optimization and calculations. SAMA is developed inPython 3.9 using the ''NumPy, Numba, time, pandas, math, matplotlib and seaborn''.

The SETP technologies currently represented in SAM include [[concentrating solar power]] (CSP) parabolic trough and dish-Stirling systems and photovoltaic (PV) flat plate and concentrating technologies. SAM uses the total installed cost, which is the sum of direct and indirect costs, to calculate the levelized cost of energy. Because how costs are assigned to each category does not affect the total installed cost, you can either choose to distribute profit, overhead, shipping, and other costs among the component categories (module, inverter, BOS, Installation) or include them as a single value in the indirect category (miscellaneous).

| ESP-r is an integrated modeling tool for the simulation of the thermal, visual and acoustic performance of buildings and the assessment of the energy use and gaseous emissions associated with the environmental control systems and constructional materials. In undertaking its assessments, the system is equipped to model heat, air, moisture and electrical power flows at user-determined resolution.
| Building geometry can be defined via CAD tools, in-built CAD facilities or click-on-grid or image. ESP-r supports a building representation of arbitrary complexity (but most users work with models of 10-50 thermal zones. Models can be exported to other assessments tools such as EnergyPlus, Radiance (visual simulations) or VRML worlds.As required, component networks can be defined to represent, for example, HVAC systems, distributed fluid flow (for the building-side air or plant-side working fluids) and electrical distribution systems. Alternatively, users can use idealised environmental controls for early design-stage explorations.
| An interactive results analysis module is used to provide many different views of simulation results, undertake a variety of performance appraisals and explore the interactions between assessment domains. Tools are provided to enable the construction of an Integrated Performance View which summarises performance over a range of relevant criteria. The range of analyses are essentially unrestricted and data can be exported to other analysis and graphing tools (but many users find they rarely need to access spreadsheets).

* [http://www.homerenergy.com/software.asp HOMER] -- National Renewable Energy Laboratory's (NREL's) computer model HOMER will be distributed and supported by a new group, HOMER Energy. HOMER is a computer model that simplifies the task of evaluating design options for both [[Off-grid]] and Grid-connected [[Distributed generation]] (DG) applications. HOMER's optimization and sensitivity analysis algorithms allow you to evaluate the economic and technical feasibility of a large number of technology options and to account for variation in technology costs and energy resource availability.
