Solar Systems Work in the Rainy Seasons.

Solar Systems Work in the Rainy Seasons.


Going Solar is a major decision for most homeowners hence they consider a number of factors before paying for it. This article is from the perspective of a couple of customers who installed solar systems from Translight about five years ago.


A question usually asked is, solar has to do with the sun so what happens in cloudy conditions and rainy seasons? Will the solar system still generate electricity? The simple answer is yes, the solar system will work in cloudy and rainy conditions. 


Cells in the solar panels absorb solar radiation from sunlight and this can be from direct or indirect sunlight. In sunny seasons, panels have access to direct sunlight and hence can generate optimum power for the home based on the system designed. The doubts come with the wet season when there are fewer hours within the day with direct sunlight. It is important to note that solar panels work with radiation and light from the sun and that clouds do not fully block these from reaching the earth on cloudy days. 


To understand this better, there is still daylight when it is raining heavily. The earth does not go all black when it rains during the day. There is always some sort of light from the sun and the cells with the panels would react with this light to generate power for the home. Putting this in perspective, a typical solar system that generates 10kWh of power in sunny seasons will generate approximately 4-7kWh of power on a rainy day. 

Solar panels generate approximately 40%-60% of their optimum generation during cloudy weather and 20%-30% of optimum generation during heavy rain. 


Translight sells hybrid systems which are connected to the grid and to lithium-ion batteries. Hence the solar system will automatically get the extra needed power from energy stored in the batteries or from the grid. Particularly in off-grid areas, systems installed by Translight can be oversized per the customer’s request to cater to uncertainties and for cloudy seasons.
