There are two distinct components that go into making a solar power system - The panels, and the inverter. It is important to understand that the solar panels you install are what harnesses the sun’s energy to produce energy equivalents, while the inverter is the mechanism that converts the solar electricity to a usable form for your residential or commercial use. You can choose to purchase and install a monitoring meter, which will keep track of your solar power usage.
To choose the best solar panel (PV), you have to factor in the efficiency of the panel you wish to purchase as compared to the industry average, the warranties available in the brand of choice subject to market standards, and cost comparisons to the efficacy of the panels. You will find that the efficiency standard in the industry ranges between 16-18%. Most brands will also offer warranties ranging between 10-25 years.
When looking for the best solar panels, you will have to look into the budget you have set for yourself and choose from the range as appropriate. Your retailer will be able to help you make the choice. They will consider the power output you require, as well as the size of your property.
