How to connect solar panel to our home electrical appliances

Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light into an electric current using the photovoltaic effect.

How to connect solar panel

it is very simple to connect solar panel to our home electrical appliances. before going to connection we have to know the main parts of this connection.

  1. solar panel
  2. controller
  3. battery
  4. inverter
  5. loads

the below connection diagram clearly show that how to make connection between solar panel and our electrical appliances. now we will see more details about this connections.

Solar Panels

Solar Panels make FREE electricity from the sun, have no moving parts to fail, and last over 25 years. They can be mounted on fixed, adjustable, or tracking type mounting systems. Getting power from the sun’s energy is not only Free , but it’s Fun to setup a solar energy system. Solar Panels come in different strengths… 5 Watts, 10 Watts, 20 Watts etc. For a typical hut at Carbeth, you’ll need at least 20 Watts worth of Solar Panels. You could have one 40 Watt Panel (ideal), or 2 x 20 Watt / four 10 Watt panels. Up to 100 Watts of Panels is suitable for huts.

Controllers

Most websites will tell you to install a Controller. These are used to ensure that your Batteries don’t over charge or over heat. For most of our systems at Carbeth, a Controller wont be necessary. As a guide, install a Controller for any system of 60 Watts or over. If you can afford it, you can buy a Controller that not only protects your Batteries from over charging, but it also has a built in Splitter – meaning that you can charge two Batteries (or “banks” of Batteries) from the same Solar Panel (or “array” of Panels).

Battery System

In the modern era, electrical energy is normally converted from mechanical energy, solar energy, and chemical energy etc. A battery is a device that converts chemical energy to electrical energy. Modern day solar kit batteries are capable of providing huge amounts of power and have a reasonably long life if looked after.

Inverters (for 230V appliances)

As indicated above, the small set ups that are suitable for hutting at Carbeth, are not really appropriate for using normal household (230V) gadgets and appliances. An Inverter lets you convert a 12V DC Supply (i.e. your Batteries), through the Inverter, into a 230V AC Supply, needed for normal domestic appliances. These are great for large scale 12V set ups – the kind that would be set up to power a normal house. These obviously have much more powerful Solar Panels and much more Battery capacity.

Loads

for loads we can consider low wattage loads something like that LED lamp, CFL lamp, fan, etc. whatever we feel important for our home loads we can connect it to our solar panels.
