Instructions to convert a house with conventional electricity into a house with a solar power system

ATTENTION:

These instructions will require you to drastically change the electrical layout of your house. It will require you to order parts from a catalog that are not included in these instructions. Please make sure to familiarize yourself with your catalog and the electrical layout of your house before using these instructions.

Also, these instructions require you to calculate complex electrical equations. If you do not believe your knowledge, as an electrician, is adequate to complete these equations then you should consult a qualified electrician to complete these instructions. Do not attempt to complete these instructions if you are not an experienced electrician.

1.0- First Section: Adapt the house with conventional electricity so it is compatible with the solar power system

In this section, you must calculate the total electricity (named potency) consumed by the house, for example:

Potency consumption of the

house

Name Circuit Number Potency

Spotlights C1 18 1687.5w

Wall Socket 1 C2 15 1500w

Wall Socket 2 C7 14 1500w

Kitchen and oven C3 2 5400W

WasherDishwasher

C4 2 6901.32W

Aux. Wall Sockets C5 5 1500W

TOTAL x0.75 13866.6w

In most cases, the regular home total potency consumed is too high for solar panels to sustain. For this reason, you need to modify the electric installation present in the house to reduce the electricity consumed.

Tips to reduce your electricity:

1. Change your conventional light system to energy savers. A conventional system’s average consumption is 50W. Using the lights energy saver, the average consumption is lowered to 18W.

2. Change your electrical kitchen and the electrical oven to gas kitchen and gas oven, if applicable.

3. Set the washer to cold-water settings, this will reduce the washer electrical potency consumed to 75%.

4. The electrical wall sockets in the house should be set for low consumption.

2.0 - Second Section: The components for your solar power system

ATTENTION:

In this section you will be determining what solar panels and solar panel accessories to select according to your house’s electrical parameters. You will select these panels from a third party catalog that is not included in these instructions. Please familiarize yourself with the catalog before continuing.

2.1 - Converter:

To select the correct converter:

1. Calculate the maximum electricity (potency) used from section 1’s table. This potency will be the out converter potency.

2. Normally the equation equals 90% (represented with the ‘n’). Using the out converter potency and ‘n’ (90%), calculate for the input converter potency using this equation:

η= Out Converter PotencyInput Converter pot ency

With the potency values, you can find the correct converter to select from the solar panel catalog.

2.2 - Solar panels:

To select the correct number of panels and correct type of panels:

1. Calculate the number of hours you experience the most solar intensity (hours you are exposed to the sun) by using this equation:

h(ho urs)=Energy grenerated by the sun( Kjm2 · year) · 0.024 ·0.0116

2. Calculate the current for the hour and day with the next equation:

Cu rrent day (day)=Potency total consumedVoltage Service

Note: Voltage service is the input converter potency from the previous step. (Step 2.1)

3. Choose a type of panel from the 3rd party catalog.

4. Calculate the electrical current necessary to match the panels number using this equation:

I . n .( A)= Energy generated by the soonPanel current

The panel current is one characteristic by the panel selected in the catalog.

5. Calculate the number of panels that are parallel using this equation:

Number panels∥¿ Current dayI . n.

6. Calculate the number series of panels you need using this equation:

Number series=Voltage serviceVoltage panel

2.3 - Regulator:

To choose the correct regulator you must know the intensity current and the number of panels by using this equation:

I . regulator=I . pane·Panels∥¿

2.4 - Accumulators:

To choose the accumulators, first you must calculate the minimum load:

3

m .load ( Ah

)= I . day+10%I.day60%I.day

x autonomy days

Once you know the minimum load, you can choose the correct accumulators in the catalog.

2.5 - Conductors to use:

There are four different circuit conductors; all four circuits use the same equation that is listed below. The four circuits are named: 1) Section of solar panels to regulator, 2) section of regulator to accumulator, 3) section of regulator to converter and 4) section of converter to the general control.

Use this equation to find the correct conductor to select from the catalog.

Section= 2 · Potency·LengthVoltage·Conductivity·voltage drop

2.6- Installation:

Panels should be oriented towards the spot where the sun rises, usually on the roof of your house. There will be varying ideal locations for each country. The panels should be placed above an iron structure, produced especially for solar panel support. The batteries, converter and regulator should be installed in a place that is weather protected.
