When choosing a solar panel, there are several factors to consider beyond just the wattage. These include efficiency ratings, warranty periods, and the availability of support and service from manufacturers. Additionally, one should consider the climate in which the panels will be used, as performance can vary significantly based on environmental conditions.
The price per solar panel is influenced by several key factors, which can vary widely based on geographic location, the type of solar panels selected, and market conditions. On average, the cost of solar panels has decreased dramatically over the last decade. In 2010, the price per watt of solar energy was about $4.50, whereas it has fallen to approximately $0.70 per watt by 2023. This reduction in price is largely attributed to advancements in technology, increased competition in the solar market, and economies of scale in manufacturing.
