When looking for the best solar panels for your home, there are many factors to consider. In this article we shall be discussing ten criteria for choosing best solar panel for home.
Types of Solar Panels
There are two major solar panels that dominates the market, namely:
Measurement of Solar Power
The ‘power’ of a solar panel is measured in watts (W) or kilowatts (KW). In a standard test condition, this figure represents the energy output of a solar panel system.
Efficiency of Solar Panel
Solar panel efficiency is measured by how much percentage of sunlight can be converted into electricity for use. Usually a regular solar panel has 15-20% efficiency.
Sometimes a solar system can deviate from its stated power (Watts) and go a little bit higher. This referred to as power tolerance. For instance: a 100W solar system can sometimes tolerate an extra 50W, thereby making it total expansion to be 150W. This deviation can be expressed in percentage. For example: +5% / -0%. This means the actual power can range from 100W – 105W.
This refers to the percentage decrease in power output when temperature increases. Usually, the average temperature is 25°C
Someone with a limited roof space would not find large panels appealing. Dimensions of solar panels are listed in L x W x H.
The weight of your solar panel is a very important factor to consider. Just in case you have a light rooftop, the best way would be to go for a light-weight solar panel or choose another location to place your solar panel.
The average years of a solar panel warranty ranges from 15 to 25 years. You must know the warranty period of your solar as given by the manufacturer.
Now you know the important factors to look forward to before deciding on which solar panel to purchase. If you need to talk to an engineer, simply call 09063063687 or email email@example.com
