How big should your Off-Grid system be?

If you are moving from a utility-connected home in the 'burbs' to an off-grid home in the boonies, you will have the opportunity (perhaps necessity) of downsizing your electricity usage. In order to calculate how large your home power system needs to be, run the calculator to check. Compare and adjust your plans according to your budget and lifestyle.
Please also refer to the daily sun hours in USA if you are USA customers, other customers from outside the coutries, please check the daily sun hours in your coutry. 

Run the System Sizing Calculator first with numbers from your current electricity usage. You can aslo refer to  the eletric appliance power consumption chart(PDF), The daily energy values listed in the PDF file are for the most efficient units in their class and the information was obtained from Consumer Guide to Home and the General Electric website. Use the power consumption to calculate the power you will need. 
These figures are approximate and do not take into account the variable efficiency ratings of solar panels and off grid inverters.

How do solar cells work?

Solar (or photovoltaic) cells convert the sun’s energy into electricity. they rely on the the photoelectric effect: the ability of matter to emit electrons when a light is shone on it. The solar cells are made of silicon and other materials which made up of at least 2 semi-conductor layers, one layer called P layer with extra electrons, another is called N layer missing equivalent electrons.  When the sun shines on the solar cells, free electrons from the P layer flow to N layer. Then it forms the electrons current. When the sun shines on the solar cells, the sun will realize photons, which contains sun energy. Many of the photons are reflected, pass right through, or absorbed by the solar cell. As these  hit the silicon atoms of the solar cell, they transfer their energy to loose electrons, knocking them clean off the atoms. The photons could be compared to the white ball in a game of pool, which passes on its energy to the coloured balls it strikes. E lectrons ar...

How to choose between a on-grid and a off-grid system

On Grid or off Grid Firstly, we should probably explain just what a grid is. A grid is a network that supplies electricity to consumers. Nothing is too complicated - it's the vehicle which supplies electricity to businesses and residences. But what’s the difference between on-grid and off-grid? Before you make decision, let’s take a closer look at the pros and cons. On grid Solar System On-grid solar systems allow you to connect your solar panel system to the electrical grid. Electricity generated by the solar panels is put into the grid during peak production. It is stored and then recovered whenever needed. On Grid systems do not require a battery, because the grid acts as the battery. With "net metering", the utility meter spins backwards and credits the solar system owner for their energy production to keep track of it.  Advantage Using renewable energy on the grid avoids most, if not all, the disadvantages of being off grid. The utility is like...
