Day 29 of #100daysofsolarnuggets

We have discussed about the basic components of a solar energy system and some important terms that we should be aware of, today we would be discussing what we need to do to implement a successful solar energy system.

What do we mean by Sizing?
     Sizing when used in solar systems designing, means calculating the requirements for setting up a solar energy system.

   We take a look at our homes, offices or wherever we plan on setting up the solar system and get the value for how much energy we consume.

  We ask questions like; the appliances we have, how much power do they consume? Are there similar appliances that consume less power? Getting answers to this questions would help you figure out the size of the solar system you need.

Once we have found out how much energy we use/need, we would need to find out the value of the photovoltaic modules (Solar Panels) that can sufficiently meet our energy needs and the Inverter capacity that would do the conversion form DC to AC.

Knowing how much energy we consume would also help us determine the capacity of the battery bank needed and the rating of the Charge controller  that would charge the batteries.

This is the first step in setting up a solar system and also one of the important.

Sizing must be done very carefully and as accurately as possible, care must be taken to avoid errors at this stage.

Any error made at this stage if not corrected would have serious consequence once we are done implementing our solar system.

There are six important stages
.1) Load Sizing
.2) Photo voltaic modules sizing (Solar Panels)
.3) Battery sizing
.4) Charge controller Sizing
.5) Inverter Sizing
.6) System wiring
