How Much Energy Do You Need?

Before starting the process of powering their homes with solar energy, homeowners should research their energy use and consider possible efficiency improvements. Homeowners should have a good understanding of their total electricity use and consider inexpensive and easy-to-implement efficiency measures before choosing solar power. The best way to determine the correct energy requirement, a commercial or home energy audit can help you understand where your home is losing energy and what steps to take to improve your home’s efficiency.

Quality Of Solar Panels

The first thing to consider when choosing solar panels is quality. This takes into account how the panel is made and the quality of the resources and material used to construct the solar panel. There are different types of manufacturers who produce panels that differ in quality, price, and efficiency. There are vertically integrated solar panel manufacturers who control every step of the production process. They attach great importance to quality and invest heavily in research and development.

What Size Solar Panel System Do You Need?

To size your solar panel system, you need to calculate how much electricity you are using and when you are using it. As a guide, a typical house consumes 20 kWh of energy per day. A five kW solar system would cover most of the daytime energy needs of such a house. Solar panels are available in two different sizes for instance, sixty cells and seventy-two cells. This refers to the number of cells of the tiny wafer of crystalline silicon in the solar panel. Their larger size makes the 72-cell panels more suitable for large open spaces such as commercial ceilings and floor mounting systems. The 60 cells are generally better suited to fit into smaller spaces, such as the attic of a house roof. To find out how much Solar Panels For Home you need, you can talk to a solar professional in your area.

How Much Will It Cost?

This is probably the factor that people take into account when comparing solar panels. The good news is that the cost of solar power has continued to drop over the years and is now 70% cheaper than just 10 years ago. But you can still determine the cost by different variables such as size in Watts, physical size, brand, quality of materials, durability or warranty period, and any certification the solar panel may have.
