Before you go green by installing a solar panel in your home, there are various aspects about this form of energy that you should be familiar with. This information will sure that you invest wisely and in the right thing, and that all your energy requirements are taken care of.

The first thing to do before you start using the solar energy is to determine your energy needs. You need to calculate the amount of energy required by your house on a daily basis. This will help you with your purchase of solar panel system, as different solar panels provide different levels of power output. Here, you will need to take into account the increased energy consumption during the winter season and the consumption during the summer months as well.

When you go out to purchase your solar panel, it will help if you do some research beforehand on the kinds of panels available in the market, their efficiencies, as well as their warranties. Ask your retailer or the manufacturer about the difference in various models of solar panels, and the power outputs they provide. You will have to decide whether to give more emphasis to the efficiency of the solar panel or to its warranty period. Also, check the power efficiency ratings of the product you are going to buy.

The second crucial decision you will have to make is about the kind of system that will supply the solar energy into your home. There are primarily three kinds of systems available in the market:

i.    Grid-tied system
ii.    Grid-tie with battery backup system
iii.    Stand-alone system

The grid-tied system is where the solar panels are tied into your current power meter. In this case, you will be using the electricity generated from the solar panels while the electricity supplied by your power company will act as a back up. In the grid-tie with battery back-up system, you will use the electricity generated by the solar panels. These panels will also charge the batteries kept for power emergencies, and any excess power will be returned to the power company through the power meter. The stand-alone system is similar to the grid-tie system except that here; there will be no batteries in case of an emergency.
