MANY peo­ple won’t want to buy a prod­uct if they don’t know how it works.

This can be the same case with so­lar en­ergy sys­tems.

For­tu­nately, it isn’t that hard to learn the gen­eral so­lar process.

Like many other prod­ucts, learn­ing how these sys­tems work of­ten comes down to know­ing what their main com­po­nents are.

So­lar pan­els are the first main com­po­nent of a so­lar en­ergy sys­tem, as they con­tain pho­to­voltaic (PV) cells.

En­ergy Ed­u­ca­tion writes that PV cells con­vert so­lar en­ergy into elec­tric­ity with the help of semi­con­duc­tors, and these con­duc­tors gen­er­ate Di­rect Cur­rents (DC) from the sun’s pho­tons.

How­ever, Ac­cord­ing to Sun Nova, most house­hold appliances run off an Al­ter­nat­ing Cur­rent (AC).

This means en­ergy sys­tems need an in­verter.

With an in­verter, DC en­ergy turns into AC.

The Grid ex­plains how so­lar sys­tems then re­quire a bat­tery bank, so that peo­ple can store en­ergy and con­tinue to use elec­tric­ity af­ter dark.

With so much elec­tric­ity run­ning, so that you can keep track of your en­ergy us­age, the last ma­jor com­po­nent is an elec­tric­ity me­ter.

Elec­tric­ity me­ters are used in homes even with­out so­lar en­ergy, so it’s not an un­fa­mil­iar process.

Your en­ergy provider will as­sess your elec­tric­ity us­age and com­pare it to how much so­lar en­ergy your home has pro­duced, and if there’s any ex­cess en­ergy sent back to the lo­cal grid, your ac­count will be cred­ited.
