Hi guys  today i will show you how to size  the battery for your photovoltaic system. This aspect is one of  the most important part of the solar system design. the link will demonstrate how to obtain the load capacity of the home also the second image to the right is an example for the blog the link will explain the necessary information  requires  https://youtu.be/iGTTUzN5Jjs .

                                                                                                                                                         

Sizing the major components in a photovoltaics system

Hi Guys  the components below shows the  images of a charge  controller and a invert-er the functions of those device   differ from each other.  while one device regulate the unstable voltage coming from the solar panels the other convert DC to AC.They are consider the heart of a solar system  here is a link that explain the various type of controllers  https://youtu.be/KPZhtGLfGn4 and this link explain the different types of invert-er  https://youtu.be/75NMRgom-6w use in a solar system. my next post would be the sizing the battery bank for the solar system also 

Photovoltaics system installation and house wiring

In Trinidad and Tobago there are many rural communities which has no electricity or they are so far way from the electrical grid that it is not cost effective for them to be connect and the only alternative is to use standby generators or photovoltaics system (PV). 

Noel's Electrical services specializes in Domestic, Commercial and Industrial installation also the installation of PV systems for the home. This blog will show case some of my resent jobs which was done in Trinidad and highlight the various components of a PV system the following parts are as follows : 

1. Solar panels 
2. Electrical wires
3. Main disconnection breakers 
4. Electrical inverters 
5. Combiner box
6. Charge Controller
7. Batteries fuses
8. Lugs 

The image above shows a topical rural house comprising of a kitchen, bath, 3 bed room and a work shop area. This client was approximately 1000 meters form the closest electrical pole.The electrical commission was charging the customer a large sum of money to obtain a electrical connection to the house. The client was able to purchase a generator but that was to loud at night and the unit could not be store in the house due to the noise, a permanent solution was derived the solar system no noise do not require refueling it only need the sun light to fuel this system.

Here in the Caribbean we are bless with this natural resource the solar system is designed with nine solar panels, and each penal came configured to output 24 volts DC at approximately 5 amps per. panel
