On Internet we can find free tools for basic or low complexity solar systems dimensioning and for certain components or accessories estimation.
Sopelia research team has carried out an exhaustive search and testing from which a new corporate website section called Free Solar Tools has been created.
Selected tools were classified into 4 categories.
Today we will analyze the second one: Consumption Calculation.
In first category we have already analyzed tools to obtain data about solar resource and other variables to consider in estimating energy solar system will provide in our location.
Now we are going to analyze tools to calculate the “load”, that is, the energy demand to be satisfied.
Tools order is not random. We have prioritized the most intuitive, the most universal and those that can be used online without download.
For this second category our selection is as follows:
1) Housing heating calculation
Approximate calculation tool developed by the Ministry of Industry, Energy and Mining of Uruguay.
Consider the variables surface, heating technology, materials, openings, insulation and roof.
Data that interests us to solar thermal system dimensioning is kcal / month.
2) Advanced Energy Efficiency Calculator
Tool to make detailed calculations of house energy consumption.
It includes a general table (all devices), a groups table (device families) and a configurable table (custom).
Last one is a version in which you can modify table data and know more accurately your particular case.
3) Hot water, heating and pool conditioning demand calculation
Spreadsheet for hot water, heating and swimming pool conditioning demand estimation.
Only Spain localizations are deployed, but can be used as template and adapt to any location by manually solar resource and other starting data entering.
Inputs: location, number of occupants and occupant’s consumption, temperature of use, collector’s number.
Outputs: collector surface, inclination, accumulation volume, yields and savings, demand and coverage calculation and comparative graphs.
4) Electrical consumption calculation
Only available for PC.
Cannot be viewed from mobile devices (Smartphone / Tablet).
Application developed by the Ministry of Energy and Mines of Peru to estimate electricity consumption based on each device power (W) and hours of use number.
5) Energy consumption calculator
Very easy operation online free basic calculator.
Different electrical devices, their power, and their daily use regime are added.
Accessing Free Solar Tools section of Sopelia’s corporate website you will find the links to have these tools and begin to configure your future solar system.
