What is SPAC ?
The Solar Panel Angle Calculator, or SPAC, is a web application.
application. Miroslav Mimic, a mechanical engineer, developed it.
The project started in 2021 as a theoretical solar calculator.
angle and sun irradiation. The first beta version was released in
August 2022,
The next version was:
- 1.0. Real-data calculations are added. A new algorithm is implemented.
- 1.1 Switching to MySQL
Possibility of choosing panels and inverters from the database - 1.2 The user interface has been changed. The database has been
extended. Add the possibility to the annual profit calculation. - 1.25 Bugs fixed, database extended. Released on March 27, 2023
- 1.29
More improvements to the UI have been made.
What can I use SPAC for?
SPAC can be used for any kind of solar investment estimation. SPAC is primarily intended for prosumers and aspiring prosumers. In other words, SPAC is intended for anyone who intends to invest in solar
energy.
For what angle calculations can I use SPAC?
SPAC can be used for fixed-angle applications
(roofs and power plants), one-axis trackers (mechanical or manual),
and two-axis trackers. In all cases, you will get results.
Is SPAC free?
Yes.
SPAC is free, has been free, and will remain free. It is written in
PHP, JavaScript, and MySQL, and it runs on the Apache2 web server.
What is the current version of SPAC?
The currently released version is 1.25 beta, published on March 27, 2023.
The currently released version is 1.29 beta, published on May 2024.
What advantages does SPAC give me over other similar applications?
SPAC is more oriented on angle setup optimizations. Rough assumptions are kept to a minimum.
SPAC does not calculate what you need, but the energy you can achieve with the
desired PV module configuration.
What makes SPAC innovative?
Unlike classic calculations that approximate the zenith of the sun and Liu Jordan’s formula, SPAC uses time irradiation for each hour, the incident angle, and all that depends on the statistical value of climate factors.
Is SPAC safe?
Yes.
SPAC is virus-free and type-safe software.SPAC does not use cookies or any technology to gather user privacy.
Can I use SPAC for project design?
No.
Although, with the help of the SPAC application, you can get all the relevant data from the desired PV module configuration (energy gain,annual money gain), SPAC is not yet intended for the creation of
ready-made projects.
What additional data requires SPAC?
In order to get the final estimate of the annual profit, you need to know the price of electricity in USD /kWh.
Is SPAC hard to use?
No.
Only three data points are required for the basic calculation:
latitude, tilt, and orientation to the south.
What is SPAC base
SPAC is written in PHP and uses a MySQL database for storage. At code, he
uses the maximum amount of object-oriented functionality that PHP can
give.
