If you're considering an off-grid solar system for your home, it's definitely a good decision to complement your electricity. To be sure, for small home systems, even if you are not a professional solar expert, you can install a solar system yourself.

Installing a solar system is not difficult and the tools required are not complicated, but there are many factors to consider when installing a solar inverter. So first let's talk about what it takes to install a solar system.

The things you need to install a solar system are PV modules, batteries, inverters, cables, PV combiner boxes, brackets, controllers, and some installation tools.

Before installing a solar system, just focus on the following questions, and everything will be done with less effort.

Here is a guide to the main factors on how to install a solar system in your home:

1. The situation of household appliances

First, you can list the main electrical loads, household appliances, and add up to its total power rating. The daily power consumption is then calculated based on each of its rated power and the number of hours of use in a day. At the same time, try to reserve a margin output rate on the basis of the maximum total power of the common household appliances you want to run.

E.g

Appliances: TV

Rated power: 100 watts

Quantity: 2 pieces

Usage time: 5 hours a day

Subtotal daily power consumption: 100Watts x 2pcs x 5Hrs = 1000Watts.

By knowing your daily or monthly electricity bill, you can further decide to use solar energy to offset some or all of your electricity. Of course, you can also get part of the supply from your city grid.

2. Solar panels and sunshine duration

In this section, you can further select a modest combination of solar panels based on the calculated total power consumption. Because most of the power will be supplied to your load through the PV panel modules. At the same time, the energy produced by the panels will depend on the amount of sunshine in your local area, the longer the amount of sunshine, the more energy is produced. Therefore, you can choose solar panels based on weather conditions and average sunshine hours. Then select your solar panel size, wattage, type and quantity.

3. Night backup time

The backup power supply is mainly provided by the local city power grid or the battery terminal.

If you encounter weak sun, rainy weather, or even no photovoltaic energy supply at night, you need to consider the corresponding battery backup time and capacity in the estimated power consumption and standby time. This is because most of the energy storage is supplied to your load by the battery at night, and the battery gets it from PV or the city grid during the day.

4. Installation layout and occasion

You can also pay attention to the layout of your home, regarding its square footage, wiring method, wiring length, and distance to install the solar system. Does the roof design or flat concrete floor have enough space for solar panels?

And make sure to connect your solar system (inverter, controller, batteries, solar panels, and other accessories) in the correct order following your supplier's instructions.
