Basic solar panel constriction hasn’t changed much in recent decades. Like the arrays that first started showing up on houses decades ago, most modern solar panels are still constructed of a silicon matrix between a front glass plate and rear polymer sheet. Solar panels have to stand up to severe weather conditions over the course of their 25-plus year lifespan. The best solar panels are engineered to stand the test of time, which requires a few basic materials and meticulous manufacturing standards.

Two important factors are considered when designing solar systems: available space and energy demand. All the nuts and bolts of solar system design hinge on these two factors, so a thorough understanding of them is essential to a well-planned solar installation.

To get started, a solar designer will calculate daily energy needs, usually by taking a look at the location’s utility bill. Next, the designer will determine the ideal number of solar panels for the project and available space to accommodate them. With energy needs and available space determined, a designer can start shopping for components.

Designing a solar system can be complicated. A designer must determine space requirements, potential shade, optimal panel pitch/angle, necessary permits, and more. Software solutions can help estimate solar energy needs and plan the best solar system.
