Photovoltaic cells in the panels absorb sunlight and generate direct current (DC) electricity. An inverter then converts this DC electricity into alternating current (AC), which is used to power homes.
Learn how to install solar panels yourself with this detailed, step-by-step guide. Discover tools, permits, common mistakes, and pro tips for a smooth DIY solar setup.

The short answer is yes—but it requires careful planning and the right installation technique to ensure your roof remains intact and your solar system lasts for decades.
The gap between solar panel rows should be around five to six inches, but it is also recommended that you leave one to three feet of space between every second or third row. This is because maintenance workers need enough room to get on the roof and make repairs whenever necessary.
When solar aluminum is utilized within a panel frame or backing, it reflects sunlight that would otherwise be lost, directing it back towards the solar cells. This enhances the amount of light that the cells can convert into electricity, ultimately leading to higher energy yields.
Hanergy's operations encompass R&D, high-end equipment manufacturing, thin-film solar module production and construction of solar power plants investing in construction of thin-film solar R&D and manufacturing bases in China, EU and United States.
Solar power plants use one of two technologies: Photovoltaic (PV) systems use solar panels, either on rooftops or in ground-mounted solar farms, converting sunlight directly into electric power.
Most residential panels convert about 20–23% of sunlight into usable electricity. Although that number may seem modest, it is enough to power homes efficiently when weather conditions cooperate.
With solar panel costs dropping by approximately 50% since 2010 and the federal tax credit currently at 30% (though under threat of elimination by December 2025), homeowners are increasingly asking: is solar a good investment? The short answer is yes, for most homeowners.
As Vietnam accelerates its transition to renewable energy, Hanoi has emerged as a hotspot for solar photovoltaic (PV) adoption. But how reliable are these systems in a city known for its tropical climate and rapid urbanization? Let's unpack the facts.
