Warranty is one of the three important criteria for choosing solar panels after efficiency and cost. Solar panels are not installed for a day or a month. These offer the most promising source of power in regions that receive a sufficient amount of sunlight. Thus, one should check the warranty period, which should be approximately 10 to 25 years.

Some people often assume that anything that is costly is always better. However, this is not always true. The industry is brimming with several types of solar panels that are quite costly but not primarily efficient. Hence, one should definitely choose an affordable alternative that is equally efficient in the long run.

Solar power, like other renewable energy resources, has many environmental and health benefits. Going solar reduces greenhouse gas emissions, which contribute to climate change, and also results in fewer air pollutants like sulfur dioxide and particulate matter, which can cause health problems.
