As an important low-carbon technology, solar energy systems are becoming cheaper and more efficient. In many cases, the competitive advantage of solar energy over traditional power sources is becoming more apparent. More and more people want to install photovoltaic systems on their roofs, but at the same time they also have a question in their minds “Is my roof suitable for solar panels?”

Roof solar panel system can generate electricity even on cloudy days. Yes, it is possible to generate electricity, but the amount of electricity generated will be greatly reduced. In rainy weather, it is estimated that photovoltaic power generation will be reduced by 50% to 90%. So, , you first have to make sure where the solar panels are installed. So that they get more than four hours of sunlight. The panels don't have to be south-facing, in fact, new research has found that west-facing panels are better, not because they produce more power than south-facing panels, but because they can be used in the afternoon or evening. It is still generating electricity normally during peak hours of electricity consumption.

Whether it is suitable to install solar energy system for home

, in addition to considering the cost of the panels and the amount of electricity they can generate, you also have to think about the current retail price of electricity. If you live in an area where electricity bills are high, installing solar panels to use some of the solar energy can save you a lot of money.
