More and more homeowners are considering solar power as an alternative to save energy, esp. in hot summer. So what are the main factors should be considered before making an investment in solar power energy?

Since solar energy is generated by the sun, check how many sunny days you get on average annually before the making the investment. Orientation can make difference. For example, in the northern hemisphere, it is best to install solar power plant to the south. When the solar panels face south, the power generation and solar radiation are also the best.

2.Shadows and occlusion
Not all south-facing roofs can be installed with solar modules. We have to consider that the surrounding trees and other buildings will not block the solar modules. Obstacles will cause a hot spot effect on solar panels, which will not only affect the overall power generation, but also cause fatal damage to the panels. It needs to be well considered before planning the solar panels layout.

3.Sufficient load-bearing capacity
The roof load-bearing capacity is an important factor that must be considered in the initial stage of the design of solar power plants. Generally speaking, installing a solar power station will increase the weight of the roof by 15kg/m2, that is to say, the total weight increase of the roof of a 3kw system is around 350kgs, and the total weight of the roof of a 5kw system is around 600kgs. It must be evaluated when adding solar plants on roof to see whether it is safe enough or not.

When the above all are well considered, it’s time to choose the solar systems providers that have proven track record in market, including solar racking, solar panels, solar inverters, etc. Art Sign is a professional designer and manufacturer of rooftop solar mounting, ground solar mounting, carport solar mounting, farmland solar mounting, also with more than 15 years production experience.
